Re: Power Supply

I'd buy or build a Mini-ITX system. the mini-ITX boards run six volts and very low wattage. It can run off an internal M2 power supply directly off your battery. I'm running one in my car, right off the vehicles 12 volt power system. I'm using a 2.1Ghz processor with 1 Gig of RAM and 80 Gig laptop drive. By using a laptop drive, the computer runs completely off the 6 volt rail.

If you don't want to go with a laptop, Mini-ITX is probably the best way to go. You could try a Mac-mini if you want to go that route, it costs about the same and is about the same size. I preferred building my own though, cost me about $500 total with case and everything but display.

Nothing special about that Power Supply except for the PRICE!

It's just a regular ATX SMPS with a 575 Watt maximum rate wattage, and an 8-pin EPS +12 Volt power cable.

The HP part number is HP 405349-001
I just THOUGHT the above model was expensive,

Uses one 24-pin ATX main power cable,

One 8-pin EPS +12 Volt power cable,

NOT to be confused with the 8-pin PCI Express power cable,

Yellow wires are 12 Volt wires. Black wires are Ground (Negative) wires.
The 8-pin EPS +12 Volt power cable has FOUR 12 Volt wires.
The 8-pin PCI Express power cable has THREE 12 Volt wires ]

I believe 4 SATA power cables,

,and a few 4-pin Peripheral power cables, ('Molex'),

Power Supply case dimensions are approximately
6 Inches Wide, 5.5 Inches Long, and 3.5 Inches in Height.
(152.40mm Wide, 139.70 Long, and 88.89mm in Height )

36 Amps combined for the two 12 Volt power rails.
(12V1 = 18 Amps, 12V2 = 18 Amps)

This is an example of a replacement SMPS,

I'm running one of these right now in a Dell Optiplex 745
Yes, even though the power cabling noted on the Tigerdirect ad is erroneous, it DOES have an 8-pin EPS +12 Volt power cable.

One 24-pin ATX main power cable
Four 4-pin Peripheral power cables
Six SATA power cables
One Small 4-pin Peripheral power cable. (Used for a Floppy Drive, or a Card Reader)

Two 12 Volt power rails. 12V1 = 23 Amps, 12V2 = 20 Amps
Combined = 43 Amps on the 12 Volt power rail.

Due to the possible electrocution hazard, I don't post info on repair.
I will state;
The capacitors need to be PROPERLY discharged, before attempting to work on the unit.
The Radial Aluminum Electrolytic Capacitors are the weakest link.

For additional questions please post in a Comment.

Gateway lx6810-01 will not boot up. Power to machine is good. Fans turn on. No post beeps. Help!

If you can open and get to the power supply look for any bad filter caps there, a outage and then power returns may have got one or more of them and if so you will be able to "see" this.

PC was caught in a lightning storm, and now will not boot (only at random). It seems like it's not getting power, when it does it'll boot normally. But when the storm hit my LAN was disabled and I had to...

Test whether it is the Power On switch, or the Power Supply. Since the LAN card bit the dust, you may be looking at a worse problem, though.

Bypass the Power On switch.

If the Power Supply comes on, the problem is the switch.
[One generic ATX Power On switch, that I have found fits many computers,

If the Power Supply does not readily come on, the problem is the Power Supply.

To bypass the Power On switch, you will be using a jumper wire on the
24-pin ATX main power cable connector.

Looks like this,

(Not necessarily the same color, and isn't located in the same position on your motherboard, as shown in the link)

Motherboard orientation:
Processor to the top, Ram Memory slots to the right.

The 24-pin ATX main power cable connector on the motherboard, is to the near right, of the number 4 Ram Memory slot.

In case you do not have the Owner's Manual, for your Inspiron 530 desktop computer,

On this page left-click on -
Owner's Manual - View - Download - (HTML 3.44MB)

Left-click on - Removing and Installing Parts
Left-click on - System Board Components
(System Board = Motherboard)

Number 7 - main power connector (ATX_POWER), is the
24-pin ATX main power cable connector, on your motherboard.

Referring back to the Playtool link, you will see a wire with Green insulation on it.
This is the Soft Power On wire. (PS_ON)

A jumper wire is used to connect it to ANY Black wire.
ALL Black wires are Ground wires.

[This is a DC circuit. There is a Positive, and a Negative.
A Ground wire is a Negative wire.

The green Soft Power On wire, is a positive wire containing 5 Volts.
You are completing a circuit.
The Soft Power On circuit.
You are bypassing the Power On switch]

There is no splicing of the wires to connect the jumper wire.
The jumper wire will go down into the socket holes, of the 24-pin ATX main power cable connector.

One end of the jumper wire goes down into the socket hole, containing the green Soft Power On wire.
The other end of the jumper wire goes down into a socket hole, with ANY Black wire.

The 24-pin ATX main power cable, is connected to the 24-pin ATX main power cable connector, on the motherboard.
Just as shown in the photo to the far right on the Playtool link.

The back of the 24-pin ATX main power cable's connector, is where the wires come in.
(The front of the power cable's connector is plugged into the motherboard)

I use a jumper wire that is approximately 3 inches long. (7.62cm)
An insulated wire. Both ends of the insulated wire are stripped of insulation, approximately 1/2 inch. (1.27cm)

One bare end of the jumper wire, goes down into the socket hole of the Green wire. Right next to the wire.
It has to go pretty far down in there.

At the end of each power wire, going into the 24-pin ATX main power cable connector, is a metal terminal pin. (Actually is a round hollow metal pin)
The jumper wire's bare end Must touch that metal pin.

The other end of the jumper wire, goes down into ANY socket hole with a Black wire.
(ALL Black wires are Ground wires)

Power Supply (Computer) plugged into power, the jumper wire is inserted.
The contact is a very BRIEF one. No more than 2 seconds.
(The Power On switch is a Momentary Contact Switch)

I suggest you also check the 12 Volt power rail. Check it with everything plugged in, inside the computer, and the computer on.
You need the Power Supply to have a load to get an accurate test.

There are 3 Voltage power rails in the Inspiron SMPS.
(Switched-Mode Power Supply, or just Power Supply for short)

A) The 3.3 Volt power rail
B) The 5 Volt power rail
C) The 12 Volt power rail.

The main one to check is the 12 Volt power rail.
[Orange wires are 3.3 Volt.
Red wires are 5 Volt.
Yellow wires are 12 Volt ]

The Positive (Red probe lead of the multimeter, is connected to any Yellow wire, coming out of the Power Supply.
The Negative (Black) probe lead of the multimeter, is connected to any Black (Ground) wire.

See if there is an unused standard 4-pin Peripheral power cable.
It has 1 Red wire, 1 Yellow wire, and two Black wires.
Connect to the Yellow wire, and to one of the Black wires.

[Multimeter function set to DC Volts. If it has it, set it to the 0 to 50 Volt scale]

11 to 13 Volts is Okay, but I prefer the voltage to closer to 12.
11 Volts indicates it's time for a new Power Supply.

My computer just stoped working. It wont power on and when I hold the power button there is just a blue flashing light

Bad Power Supply.
Weak Voltage power rail.

The Pavilion a6000n desktop computer uses an ATX style of power supply, and is rated at 300 Watts.
(Probably made by Delta Electronics)

The ATX style of Power Supply is used in over 85 percent of PC's. Very common unit.

[Case size is approximately 6 inches Long, 6 inches Wide, and 3-1/2 inches Tall ]

What you are looking for is an ATX power supply with at Least 300 Watts, and the correct power cables.

Note that a computer only uses the power it needs, and No more.

Wouldn't matter if you had a 10,000 Watt Power Supply, (Exaggeration), and the computer only needed 100 Watts, it will only use 100 Watts.

(Surfing the internet typically uses 100 Watts.
Computer. Monitor uses it's own power, and is separate from this figure)

This is HP Support > Pavilion a6000n desktop computer > Specifications,

This is HP Support > Pavilion a6000 desktop computer > Motherboard Specifications,

1) Scrolling down the page, and looking at the photo of the motherboard, you can tell the Power Supply must have a 24-pin ATX main power cable.

To the right of the Blue, and Black ram memory slots is the 24-pin ATX main power cable connector, on the motherboard.

It is White in color, and consists of 2 rows of 12 socket holes.
24 total.

On the illustration it is marked as - ATXPOWER.

This is a closer look at a typical 24-pin ATX main power cable, and it's respective connector,

Note the Lock on the side of the connector. The Lock is hinged in the middle, (Plastic), and operates like a see-saw on a playground.

Squeeze the top of the Lock in to remove the 24-pin ATX main power cable.
ONLY gently pull up on the connector, and NOT the wires.

[This action brings the hooked end of the Lock away from a 'Bump', or protrusion, that is present on the female connector, on the motherboard ]

2) The Power Supply must also have a 4-pin ATX +12 Volt power cable.

On the illustration where it states Socket AM2 is the Processor socket.

To the left, and down a little of the Processor socket, is a blank square.
The writing under it is illegible.

This is where the 4-pin ATX +12 Volt power cable plugs in.

On the motherboard photo it is to the left of the white Processor socket, and is square in shape, with four socket holes.

This is a better look at a 4-pin ATX +12 Volt power cable, and it's respective connector,

Color of the plastic used in the connectors, does not matter.

3) Looking at the Specifications page, you will see that the Power Supply must have at least 1 SATA power cable.
It's used for the 250GB SATA harddrive.

Closer look at a SATA power cable, and it's respective connector,

If the SATA harddrive in your computer has a place for a SATA power cable, and a 4-pin Peripheral power cable, ONLY use the SATA power cable.
DO NOT use both.

4) Again looking at the Specifications page, the Power Supply must have at least two, 4-pin Peripheral power cables.
Used for the optical drives.
(DVD drives)

A closer look at a 4-pin Peripheral power cable, and it's respective connector,

There may be more 4-pin Peripheral power cables needed, to run any computer case fans.

[The Processor fan plugs into the motherboard ]

An example of an ATX power supply that is 500 Watt rated, and has the correct amount of power cables, plus the correct type of power cables,
