Kind of hard to give you a cable diagram, Roslyn, when you haven't stated what motherboard manufacturer and model number.

Or computer manufacturer and model number.
(Back of computer next to Windows product key; or up on side of computer tower )

So we'll wing it..............

Widetech the Max. A modular line of Power Supplies.

1) Main power cable;
It will be either a 20-pin ATX main power cable, or a 24-pin ATX main power cable.

The WTM (Widetech the Max) will have a braided thick cable, that will have a 20-pin connector, and a 4-pin connector.
Looks like this,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20plus4

The 20-pin connector, and the 4-pin connector, should have a white arrow on the side. The arrows point to each other, when the two connectors are properly aligned with each other.

So, ATX main power cable plugs into Power Supply, (If removable), and 20 + 4-pin connector plugs into motherboard.

When the hooked end of the Lock, on the side of the power cable's connector; is over the Tab on the motherboard connector; the power cable is deemed to be plugged in properly, and tightly.

Note*
Orange wires are 3.3 Volts
Red wires are 5 Volts
Yellow wires are 12 Volts.
Black wires are Ground wires. (Also are Negative)

Note that the extra 4-pin power cable, that attaches with the 20-pin ATX power cable; has TWO Yellow wires, a Red wire, and a Black wire.
This way you don't accidentally somehow, plug the following power cable, in with the 20-pin ATX main power cable,


2) 4-pin ATX +12 Volt power cable:

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

When Processors started using more power, than just the processor socket (Motherboard) could deliver, this power cable was brought out to help carry the load.

Note*
TWO Yellow 12 volt wires, and TWO Black ground wires.

3) 8-pin EPS +12 Volt power cable:

http://www.playtool.com/pages/psuconnectors/connectors.html#eps8

Brought out for motherboards supporting multiple Processors, (CPU's), such as a server computer; but with processors needing more, and more power; is used quite frequently by motherboard manufacturers now.

NOTICE the power wires. The color code of the insulation of the wires.
FOUR Yellow wires (12 Volt), and FOUR Black wires. (Ground)
NOT to be mixed up with the following power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#pciexpress8

This baby plugs into a GRAPHICS CARD (Video Card. Same/same)
A PCI Express graphics card, IF it uses one.

The PCI-Express x16 slot on the motherboard, is only capable of delivering 75 Watts.
This power cable can deliver UP TO an additional 150 Watts.

It is an upgrade of this power cable,

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

The 6-pin PCI Express power cable was brought out, to provide more power for a graphics card.

75 Watts.

So now you have the PCI-Express x16 slot on the motherboard capable of 75 Watts, and the 6-pin PCI Express power cable capable of 75 Watts; for a total of 150 Watts available for a graphics card.

PCI-Express x16 slot on motherboard, and 8-pin PCI Express power cable?

225 Watts.

This power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#eps4plus4

Is for a motherboard that uses a 4-pin ATX +12 Volt power cable, OR an 8-pin EPS +12 Volt power cable.
Is a combined power cable if needed, just like the 20 + 4-pin ATX main power cable.

This power cable is a SATA power cable,

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

Used to plug into a Harddrive, or Optical Drive. (CD/DVD drive)

NOTE*
IF your SATA harddrive has a provision on the back; to plug in EITHER a SATA power cable, AND a 4-pin Peripheral power cable; ONLY use the SATA power cable.

Using BOTH power cables will burn up the harddrive. May not happen immediately, but I ASSURE you it will happen.

4-pin Peripheral power cable, is also erroneously known as a 'Molex' power cable.
Molex was the first company with the CONNECTOR design. The name stuck. Kind of like calling an adjustable open-end wrench, a Crescent wrench,

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

[ IDE (PATA) harddrive shown in photo. Not a SATA harddrive ]

Note that between a SATA power cable, and a SATA data cable; the SATA power cable's connector is longer.
SATA power cable connector has 15-pins.
SATA data cable's connector has 7-pins,

http://en.wikipedia.org/wiki/File:SATA_ports.jpg

Note the L-shaped opening of the SATA data cable's connector; and the L-shape of the motherboard connector.
The SATA power cable has the same L-shaped opening.

NOTE that color of connectors does NOT matter.
Could be green with pink polka dots.
It is the wire color code, and connector SHAPE, that matters.

[Applies to ALL cables, and connectors}

Sometimes the SATA power cable, and SATA data cable connectors; have a lock on them.
May not see it very well. It is usually a slightly raised bump on the connector. This is depressed with a thumb nail to unlock.

Unlock WHEN installing, and removing.

ALWAYS use the connector when plugging in, or unplugging a cable.
DO NOT pull on the wires.
(Even if you have to stand on your head, and whistle 'Dixie')

I lay the computer opening side UP, on a static free towel, on a table. Much easier to get to the cabling.

ONLY plug in the cables you need, to the Power Supply.
That's what Modular cabling is all about.
Gives more room when not using unnecessary cables, and more air flow through the computer case; for cooling.

I just installed a ThermalTake TR2 600 power supply. It is Modular Cabling also.

I'm willing to bet you didn't plug the Processor (CPU) power cable in.
Either a 4-pin ATX +12 Volt power cable, OR an 8-pin EPS +12 Volt power cable.

Make sure the Ram Memory is seated tightly also.
It get's bumped loose when installing a Power Supply.
No,.....you CANNOT just visually inspect, and let it go at that.

You HAVE to remove ALL ram memory modules ('Stick'), and plug them back in again; to be ASSURED that they/it are seated tightly, and correctly.

Well that about does it for me kid, post back in a Comment if you have additional questions.

Regards,
joecoolvette

Black screen after updateing the bios


If you did a backup before you upgraded the graphics driver then I would restore this. I would then do upgrades one step at a time with a full backup between upgrades.

If you don't have a backup then I would take the opportunity to rebuild the system and take backups at various stages.

By doing the backups regularly you wont get caught out by so called upgrades which actually do the opposite.

If there is noise "beep" then it has RAM issue/RAM port. If is not noising then it has motherboard issue. I guess you need to take it to the technician and ask him to fix or replace it.

I want to upgrade the mother board in my Vaio PCV-RZ44G Desktop so that I can run Windows 8. What board forms are compatible and is an Intel I3 or I5 CPU better?


You would be better off applying the money to a new computer. You are opening "Pandora's Box" . You will end up with a old case with ALL new components. That may or may not work, A.K.A., "pain and heartache".

I want to upgrade my power supply for the dell gx280 small desktop


Sorry to say that a 260w PSU is the largest PSU you will get for this system as that is all the M/B is safely rated to any higher than that and it may cause a fire or worse. I run a Dell GX270 and this is maxed out on a 260w PSU. This system will only be upgradeable to these specs :

3.2Ghz CPU ( Note they must match existing letters on CPU.
3Gb Ram under XP, 4 Gb under Vista or Win 7. ( Note win 7 will run very slowly )
256Mb PCI Card or 512Mb AGP (4X or 8X )
500Gb IDE or SATA HDD
DVD Burner max ( Blu-Ray will not work as it is too advanced ).

Even the tower model of these systems only have a 260w PSU max due to limited power rating for the M/B. Tower PSU is able to be swapped out just like any other tower but the fact remains that the M/B is only rated to 260w and if you use a larger PSU it may cause a fire or worse. I hope this helps.

Monitor comes on momentarilly, then screen turns black. when power is turned off and back on again, screen comes on for a second, then goes black again. Is this a bad monitor?


The only problem that causes the power on and off is a bad power supply. Go onto http://www.ebay.com and search for the monitor (power supply). My dad's old LCD screen had a bad power supply, but I found my old printer power cable (HP PSC 750 All-in-One Printer), and the monitor turned on successfully. It's not a bad monitor, unless the PSU hookup is like the PC ATX/Baby-AT PSU cable, then it might be the issue. Monitors before 2004 or 2005 have the ones, like the HP PSC 750 uses. The monitor is either defective, or the power supply is dead.

p.s.: check the voltage, amp usage, etc. on the PSU for the monitor for better results.

Black screen,then test screen.Did the mobo or vid card fry?


Hi,

if you fried a psu, it was probably caused by a motherboard fault.
You could try removing the geforce card, and try plugging the monitor into the onboard graphics port if it has One. These boards also suffer from bios chip problems, so a replacement bios chip may be another suggestion. failing any of this the motherboard is faulty and should be replaced.

Black screen with AGP video card update


you really didn't need a new psu for that videocard, but it can either be a burned videocard or the monitor can't support the refresh rate the videocard is outputting.  although, the card really should default to its lowest setting upon installing in a new system, try connecting another monitor.  if you get a screen, thats good, if not, try booting into safe mode holding f8 right before the windows loading screen appears.

1inch black line down right hand of screen


Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!
