Looking for power supply core its lcd2000 12 volts 62 watts need fast

It doesn't work that way.
Watts are a form of measurement of power flow.
For example, a 40 watt bulb uses power at a rate of 40 watts. The amount of power could be 5 volts, 110 volts, or 500 volts.
Its like measuring how fast water flows thru a hose, not how much water.

First thing to check with a desktop computer problem, is the Power Supply.

No sir,....cannot ASSUME power supply is good, because LED's light up, and fans spin.

1) If ALL the LED's were lit up at once, they would use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor (CPU) can use 51 to 125 Watts of power.
Just depends on what Processor it is.

Intel Core i7, model 950?

http://en.wikipedia.org/wiki/List_of_Intel_Core_i7_microprocessors#.22Bloomfield.22_.2845_nm.29

Up To 130 Watts. (TDP. Thermal Design Power, or Thermal Design Point. Whichever you prefer )

Exceeded the spec's I stated.

Power Supply with a weak voltage rail, will have enough power to turn the wimpy little LED's on, and spin fans; but will NOT have enough power to turn the Processor on.

How to know?

Test the 3 main voltages coming out of the Power Supply, with a multimeter set to DC Voltage;

Or,

Temporarily substitute the Power Supply, with a KNOWN to be good, Compatible one.

Borrow from a working computer. Then you can diagnose if this is the problem; and can put it back in the working computer.

The motherboard you have needs at least 150 Watts.
CPU = 130 Watts
Each ram memory module = 15 Watts (DDR3 Sdram)
Harddrive and optical drives around 25 Watts each.
Fans 2 to 3 Watts each.

Your CPU requires 3 ram memory modules at least. 6 can be used.
So........
150 + 130 + 45 + 50 + 6 = 381 Watts.

Bare minimum is 400 Watts, and you should have a 500 Watt power supply. Need at least 10 percent over what is needed; but why play around? 500 Watts.

Have a multimeter?
(An economical model can be purchased for as little as $5 to $12)

1) ALL Orange wires are 3.3 Volts
2) ALL Red wires are 5 Volts
3) ALL Yellow wires are 12 Volts.
ALL are DC Voltage.

In comparison two D cell flashlight batteries produce 3 Volts DC.

ALL Black wires are Ground wires,

http://en.wikipedia.org/wiki/Computer_power_supply#Wiring_diagrams

(Your SMPS is of the ATX technology)

Need guidance in performing this? Post back in a Comment.

Also:
When checking a desktop computer, after checking power; and this does no good;

Have ONLY the Processor, processor fan hooked up, and Ram Memory.
That means disconnect EVERYTHING else.

Harddrive, (Power and data cable), optical drive, (Power and data cable), computer case fans, (NOT processor), Card Reader cables, Front Panel USB cables, etc.

All you are trying to do at this point, is see if you can pull the BIOS Setup screen up.
If so then add Harddrive, and computer case fans.

[ Note* This is a fast test. BIOS Setup screen comes up, turn the computer off.
CTRL key, ALT key, and Delete key AT SAME TIME.

You don't want to overheat the motherboard. Primarily the Northbridge chip, and Southbridge chip; of the motherboard chipset.

You're just performing a fairly fast test ]

Intel Core i7 requires THREE ram memory modules, at least.
People have used two, but do not apparently understand the Nehalem technology, and using an Intel Core i7.

[ By the way,............if your computer comes to life..........RUN!

It's an inanimate object! lol!

What evil lurks in a desktop computer's mind? (Processor)

http://www.youtube.com/watch?v=2rqd8Oa-sA4

Probably not the jumper settings Nethen.

Check the Power Supply's three main voltages, with a multimeter set to DC Voltage.
3.3 Volts, 5 Volts, and 12 Volts.

No, don't guess. You could have a Power Supply with a weak voltage power rail, and have fans spinning, and LED's lighting up.
Why?

1) If ALL of the LED's were on at once, they would use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor can use 51 to 125 Watts of power.
Just depends on what Processor it is.


Hmmm, lemme see...

Socket 478 processor socket, and Intel 865G motherboard chipset;
Supports Intel Celeron, Celeron D, and Pentium 4.
Prescott, Northwood, and Willamette Cores,

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_4_microprocessors

http://en.wikipedia.org/wiki/List_of_Intel_Celeron_microprocessors#Celeron_D_.28single-core.29

I'm going to say 55 to 89 Watts. Again, it depends on what Processor.

This means you would have enough power to turn those simply LED lights on, and fans; but NOT enough power to TURN the Processor on; with a Power Supply that has a weak voltage power rail.

OR,
Use a KNOWN to be good, Compatible power supply, for a temporary test unit.

Before you start though, take a CLOSE L@@K at those Electrolytic Capacitors on the motherboard.

1) HP xw6200 Workstation desktop computer,

http://h18000.www1.hp.com/products/quickspecs/11975_div/11975_div.HTML

Power Supply: Maximum rated Wattage - 500 Watts.

XFX ATI Radeon HD5750 graphics card,

http://www.ebay.co.uk/itm/2GB-ATI-Radeon-HD-5750-1GB-HDMI-1080p-BluRay-EyeFinity-Gaming-Graphics-Card-/120973408169?pt=UK_Computing_Computer_Components_Graphics_Video_TV_Cards_TW&hash=item1c2a93b7a9&_uhb=1#ht_4735wt_1080

Yes.


1) Install the software F-I-R-S-T, then physically install the graphics card.
Windows running, put the Installation disk that comes with the graphics card, into the CD/DVD drive.
Load all software. The drivers, and Catalyst Control Panel.

Windows will NOT use the software until the graphics card is installed, so don't worry about not having graphics in the meantime.

2) Computer unplugged from power FOLLOW Anti-Static Precautions.

Anti-Static Precautions:
Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.

Relieve your body of Static BEFORE reaching inside your computer, AND before removing any parts out of their anti-static bags, or cartons.

Computer on a table, computer unplugged from power, computer case open;
TOUCH an unpainted surface, of the metal frame of the open computer case.
This action will relieve your body of Static.

IF you leave your computer in the middle of working on it, be SURE to Touch the metal frame again upon your return.

3) Physically install the graphics card.
(The Lock Lever on the PCI-Express x16 slot, goes UP to install a graphics card, or to remove a graphics card. It looks as though you should push down on it)

http://www.txcesssurplus.com/servlet/the-9225/HP-408544-dsh-001-xw6200-WorkStation/Detail

Looking at the black PCI-Express x16 slot, with it's green Lock Lever, it looks as though there should be room for the graphics card.

Looking to the right of the green Lock Lever, look at the 4 gold colored Choke Coils. It may be tight, but the graphics card should clear the first two.

Areas of concern, though;

1) Power Supply:
The XFX Radeon HD5750 graphics card, requires a minimum of a 400 Watt Power Supply.

The graphics card doesn't use 400 Watts, of course. This is the minimum power requirement by the graphics card manufacturer, and based on the power the card needs, and the rest of the computer.

XFX, just like all graphics card manufacturers, uses a computer system set up to the maximum, for a test unit.

Gamer style motherboard.
Powerful Processor, that is probably a dual core, or quad core.
Maximum amount of ram memory.
Two optical drives
Two or more computer case fans.
Two or more harddrives.

You get the picture.

Power consumption has to be based upon what each individual hardware component will use, AND the graphics card.

Power Supply:
Problem is, the computer has some age on it. From searching it seems to have been made in 2004. Makes it 8 years old now.
Makes that Power Supply 8 years old now too.

A) Pre-built computer manufacturers, such as HP, Gateway, Lenovo, Toshiba, etc., have their components made by someone else.
The Power Supply is one such component.

Usually a generic Power Supply manufacturer, such as Bestec, or HiPro, or Delta, for HP computers.
Low quality electronic components are used in these power supply's.

Isn't a big deal usually, until you start to tax the limit on the Power Supply, such as installing a powerful graphics card.

Power Supply manufacturers also had a great tendency, to overate their Power Supply's back in the day. Made the Power Supply sell better, 'fudging' the actual Wattage rating.

Wattage was actually more like 60 to 70 percent, of what was stated.
300 Watts (60 percent) to 350 Watts (70 percent) is more actual.

The XFX ATI Radeon HD5750 also requires a 6-pin PCI-Express power cable, coming from the Power Supply, and connected to it.

The maximum amount of Wattage a PCI-Express x16 slot can deliver, is 75 Watts.
The 6-pin PCI-Express power cable delivers an additional 75 Watts,

http://www.playtool.com/pages/psuconnectors/connectors.html#pciexpress

"This cable is used to provide extra 12 volt power to PCI Express expansion cards.
PCI Express motherboard slots can provide a maximum of 75 watts.

Many video cards draw significantly more than 75 watts, so the 6 pin PCI Express power cable was created.
These high-power cards draw most of their power from the 12 volt rail so this cable provides only 12 volts."

(Yellow wires are 12 Volt wires. Red wires are 5 Volt wires, Orange wires are 3.3 Volts. All are DC voltage. Black wires are Ground wires)

Will your Power Supply have a 6-pin PCI-Express power cable?
I doubt it.
In the Playtool link, see the 6-pin PCI-Express adapter power cable, shown on the right?

Takes TWO 4-pin Peripheral power cables,
(Commonly misnomered as a 'Molex' power cable),

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

If you are going to use one of these power adapter cables, you NEED TWO 4-pin Peripheral power cables!

HAS to have TWO Yellow 12 Volt wires going to it.

Will using a 6-pin PCI-Express adapter power cable, and One 4-pin Peripheral power cable work?
Most of the time yes.

PROBLEM is,
Over time the;

1) PCI-Express x16 slot contact pins -> BURN

2) Gold plated contact pins on the bottom of the graphics card -> BURNS

3) Connection on graphics card for the 6-pin PCI-Express power cable - BURNS

4) 6-pin PCI-Express power cable's connector -> BURNS

No if's, and's, or but's; it WILL happen.
Result is usually throw the motherboard away, and the graphics card.

So you may be looking at getting a better Power Supply.
Here is one example that will work,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=899124&CatId=1483

A) 600 Watts. Gives you an additional 100 Watts of power. Less strain on the Power Supply.

B) 120mm fan. A larger fan turns slower, therefore makes less noise.
Puts out more air flow than an 80mm fan, even though it turns slower.

C) Has all the power cables required, plus more.

D) Has TWO 12 Volt power rails.
12 Volt 1 is capable of 23 Amp's.
12 Volt 2 is capable of 20 Amp's.
Total combined Amperage for the two 12 volt power rails is 43 Amp's.

Gamer computer?
Not IMHO. Uses ECC ram memory.

That is Error Correcting Control ram memory. The ram memory runs the data through it twice, in order to make sure everything is correct, before using the data.
This is the type of ram memory a Server computer uses.

Could be wrong, and it could be used as a gamer computer, though. We will see when you are done, IF this is the intent.

[ http://en.wikipedia.org/wiki/ECC_memory

Reasons for not using ECC:
"A performance decrease of around 2-3 percent, depending on application, due to the additional time needed for ECC memory controllers to perform error checking;"

HP Compaq dx2300 Desktop PC?

http://h20000.www2.hp.com/bizsupport/TechSupport/Home.jsp?lang=en&cc=us&prodTypeId=12454&prodSeriesId=3352967&lang=en&cc=us

90 percent of desktop computer failure, cab be attributed to;

A) The computer is dirty inside, to include the Power Supply.

B) The Power Supply is bad

Suggest you start with cleaning the inside of the computer out, but suspect the real problem is the Power Supply.

Why?

Because the CD-ROM is not working.

Primer:

Your Power Supply converts your household/business AC electricity, into 3 low main DC Voltages.

Depending on your country;
USA = 120 Volts AC
Europe = 220 Volts AC
Australia = 220 Volts AC
Japan = 100 Volts AC

This is converted into 3 low DC Voltages for the computer;

A) 3.3 Volts (DC)
B) 5 Volts (DC)
C) 12 Volts DC

Each of the above is a voltage power rail.
The amperage for each power rail is stated on a label, on the Power Supply.

Voltage times Amperage = Wattage

Again, Voltage x Amperage = Wattage

All of the amperage of the voltage power rails are combined, (Added together), to equal the maximum Wattage, the Power Supply will deliver.
This should be stated on the Power Supply label also.

A) IF, all of the LED lights were on at once, they would use less than 1 Watt of power.

B) EACH fan uses 2 to 3 Watts of power.

C) A typical Processor can use 51 to 125 Watts of power.

[ Intel Pentium Dual Core E2160? Can use up to 65 Watts,

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_Dual-Core_microprocessors#.22Allendale.22.2C_.22Conroe.22_.2865_nm.29 ]

You press the Power On button. This in turn presses against a Power On switch,

http://www.directron.com/atxswitch.html

This in turn, activates the Soft Power On feature of the Power Supply, and turns it on.

The first chipset to receive power is the BIOS chipset.

The BIOS program looks to see what devices are connected, does a Ram Memory count, turns the Processor on, then hands the computer over to the Operating System.

[ Windows XP and Windows 7, are two examples of an O/S ]

Primer over.

Your Power Supply provides enough power to turn the Processor on, then falls to it's knees. Doesn't have enough power to keep the Processor on.

[ A typical CD/DVD drive requires 15 Watts of power. It isn't there when all of the other hardware needs power first ]

Suggest you find a Power Supply that is KNOWN to be good, and COMPATIBLE, for a test unit.

Or you can test the 3 main voltage's coming out of the Power Supply, with a Multimeter set to DC Voltage.

Or you can just replace the Power Supply.

I would prefer you test with another unit, or test the voltages, before you spend your hard earned money.
It's up to you.

Diagnose the problem first. I could be wrong with the above, but if you diagnose using a test unit, or test the voltages, we will know whether the Power Supply is the problem.

Always start with the power First.

Perhaps there is an unused computer you may have access to, and can borrow it's Power Supply for a test unit. Has to be KNOWN to be good, and has to be COMPATIBLE.

What is Compatible? Means it has to have at least the minimum power cables, and the Power Supply must fit in the computer case.

(It is an ATX power supply)

Need recommendations for a Power Supply, post in a Comment.
Also will step by step guide you in replacing.

Regards,
joecoolvette

pls replace your power supply to 500 watts. . . thats all you need..

thanks. . .

Bad Power Supply. Weak Voltage power rail.

Not enough power to turn the Processor on, and keep it on.

1) ALL those LED lights together, use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts

3) A typical Processor can use 51 to 125 Watts. Depends on what Processor it is. (Older Processors use less Wattage)

When you press the plastic Power On button, you are contacting a Power On switch inside it.
(Typical ATX Power On switch,

http://www.directron.com/atxswitch.html )

When an ATX power supply is plugged into power, there is a 5 Volt Standby power, present inside the power supply.

Pressing the momentary contact power on switch, closes a circuit that directs the 5 Volt Standby power to 'excite' the power supply, and turn it on.

The first chip to receive power is the BIOS chip.
[Chip and Chipset are slang terms for I.C.
Integrated Circuit.
BIOS stands for Basic Input/Output System]

BIOS,

http://en.wikipedia.org/wiki/BIOS ]

BIOS looks to see what devices are installed, does a Ram Memory count, TURNS the Processor on, and hands the computer over to the Operating System.
(Windows XP is one example of an O/S. Operating System)

The LED lights receive power, so do the fans, and the Harddrive. When it's time for the Processor to kick on, there isn't enough power, and the Power Supply 'falls to it's knees'.

Replace the Power Supply.
It's just one of the basic ATX power supply's that are readily available in a multitude of places.
The Wattage is 300 Watts.

The ATX form factor for this power supply, (Size and shape), is approximately 6 inches Long, 6 inches Wide, and 3-1/2 inches Tall.

Power cables needed:
(Continued in a Comment)

If you can provide the Make

1) So you tested the monitor on a working computer? Reason I ask, is that you will be testing the monitor cable also.

If it is a monitor with a detachable monitor cable, suggest you test the cable also.

2) Each graphics (Video) adapter card has it's own specific driver.
The driver should be installed Before, the graphics card is installed.

Otherwise Windows will 'break it's neck', to find a compatible driver, from it's thousands of generic drivers.
Won't do. You will get a driver conflict.

Windows: 'Which driver do I use? These or THESE?"

Kinda' hard to do, since you can't see graphics on the monitor.

I would like to suggest you diagnose the Power Supply to start with. (After checking the monitor cable)

It may seem that the Power Supply is okay, but it could have a weak Voltage power rail.

Enough power to light LED lights, and spin fan's, but not enough power to turn the Processor on.

1) ALL the LED's use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts.

3) A typical Processor can use 51 to 125 Watts.

2) Information on the AMD Athlon 64 3500+,

http://en.wikipedia.org/wiki/List_of_AMD_Athlon_64_microprocessors#Athlon_64

Can use up to 67 Watts, or up to 89 Watts. Depends on what Core it is.
(Clawhammer Core, Newcastle Core, Winchester Core, Venice Core, Manchester Core, or San Diego Core)

(Also uses an MSI K8NGM-L motherboard. Below for specifications only,

http://www.newegg.com/product/product.aspx?Item=N82E16813130041 )

A) Not to down eMachines, (I have an old T1090 in my shop that works great), but they are budget computers, and use budget parts.
One being the generic Power Supply that is used.

B) The computer could be dirty inside, as well as inside the Power Supply.

The cooling components for the SMPS, (Switched-Mode Power Supply,) are it's Fan, and Heatsink's used inside.

Once a layer of 'Gunk' covers these cooling components, the cooling capacity drops tremendously.

Heat = Wasted Energy

The more heat, the more the Power Supply strains to keep up with the call for power.
Eventually hardware components inside the Power Supply fail, and the Power Supply is toast.

You can test the Power Supply voltages.
You can use a multimeter if available, or an economical unit can be purchased for around $5 to $12, that will suffice for testing.

You can also use a power supply tester.
One example:

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=5250576&CatId=5471

Voltages produced by the SMPS used in a T6528 are,
A) 3.3 Volts (DC)
B) 5 Volts (DC)
C) 12 Volts (DC)

Testing should be done on the 12 Volt power rail.
11 to 13 Volts indicates a good Power Supply.
Less than 11 Volts means it's time to replace.

Orange wires are 3.3 Volts
Red wires are 5 Volts
Yellow wires are 12 Volts.

All the color coded Voltage wires, lead back to one individual power rail, for each Voltage produced by the Power Supply.

You can test any Yellow wire to test the 12 Volt power rail.

With a multimeter, the Positive (Red) probe lead connects to the power wire to be tested.

The Negative (Black) lead connects to ANY Ground wire.

ALL Black wires are Ground wires.
They all go back to one central Ground source inside the Power Supply.

[Power Supply unplugged from power before attaching probe leads. After connecting, the power supply is plugged back into power, and the Power On button is pushed ]

(Two C cell flashlight batteries produce 3 Volts DC)

Power supply failure, or the Power On switch. (Behind the Power On button)

My money's on the power supply failure.

Why?
It's the leading case of computer failure. The power supply is the 'Heart' of a computer. (Processor is the 'Brain', Motherboard is the 'Building Block')

Computer was on for an extended length of time? Was the computer ever turned off, and the inside of the computer cleaned out on a regular basis?
(Power supply also)

Normal procedure is to unplug the computer from power, open the computer case, and use a can of compressed air for computers.

Power supply light is on?
This is what is going on.

Computer power supply's are rated in Wattage, for power.
Voltage times Amperage = Wattage

The HP 5188-2627 power supply, supplies three main voltages. It has three main voltage power rails.

1) The 3.3 Volt rail
2) The 5 Volt rail
3) The 12 Volt rail

Your power supply has a weak voltage rail.

A) ALL the lights use less than 1 Watt of power.
B) EACH fan uses 2 to 3 Watts
C) A typical Processor uses 55 to 125 Watts.

There isn't enough power from the power supply to turn the Processor on.

Solution is to replace the power supply.
It may seem a little daunting for someone replacing a computer power supply, the first time.

After you have replaced one, it becomes easier.
Essentially you are just opening the computer case, unplugging the power cables from the power supply to the various hardware components, and removing the power supply.

To install just reverse these steps.

The power supply in your computer is a 300 Watt power supply. (Maximum wattage)

The size, and shape of the power supply, is one that is used in over 90% of personal computers.
ATX

What I would I recommend for a replacement?
Not one of the cheap quailty Hi-Pro's that HP used, that's for sure!

An OCZ StealthXStream 400 Watt is what I would recommend.
Why?

1) It will fit
2) It has a 140 Millimeter fan compared, to the 80mm fan that your old power supply has.

A larger fan means it will run quieter, due to the fact that it won't have to turn as fast, in order to put out as much air.
Will actually put out more air than that 80mm fan, and will spin slower.

3) Has two 12 Volt power rails.
One 12 Volt rail can deliver 17 Amps.
The other 12 Volt rail can deliver 14 Amps.

You can add the two 12 Volt power rail Amp's together, for 31 Amps.

Means less strain for the power supply, to keep up with the tasks.
(Your old power supply probably has an 18 Amp, 12 Volt power rail)

4) Has all the power cables you'll need.

5) Price, and reliable quality.

This is one place that carries them,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4675269&CatId=1078

There are other places also. Not advertising for the above website, nor the power supply manufacturer.
Just my personal preference, based on experience with both.

A computer only uses the power it needs, and NO more.
If you install a 1000 Watt power supply in your computer, and the computer only needs 100 Watts, it only uses 100 Watts.

(Surfing the internet typically uses 100 Watts of power. Like a 100 Watt light bulb)

This may help guide you in replacing the power supply,
