Graphics card PSU problem?

Hi guys, wondered if you could help troubleshoot an issue I've been having recently.

I play a lot of Tf2 and recently my game has started stuttering then I'd get a black screen and returned to my desktop.

I initially thought it was just a bug in the game, it has happened before but now i cant play the game (or any other to that matter) without it happening.

I then noticed a red led on my Graphics card which i was sure wasn't there before.



So after doing some research i found what the codes for the led's represent:


•D14 (R753) 6 Pin power unplugged
•D13 (R724) 8 Pin power unplugged
•D15 (R819) Overheating (Thermal issue)
•D5 (R323) GPU-1 (Master) No power
•D7 (R570) GPU-2 (Slave) No power

So it would appear that GPU-1 has no power.

After discovering this I reseated the graphics card and cables, rebooted and the led was longer on (great i thought) but this only lasted for a couple days until i started playing some GTA and low and behold 10 minutes into the game it happened again.

So do you think this might be a direct issue with the graphics card or maybe an issue with the ageing PSU starting to deteriorate and not supplying enough power?

Sorry for the lengthy post, any advice would be much appreciated.

System specs:

GPU: Power Color Radeon HD 4780 X2
CPU: Q6600 @3.02GHz
RAM: 2x2GB Corsair Dominator XMS2 DDR2 PC2-8500C5
HDD:Western Digital Black 1TB
OS:Windows 7 Service Pack 1
Motherboard: Abit IP35 Pro XE Intel P35
PSU: Corsair TX 650W ATX2.2 SLi Compliant PSU

Bought from Overclockers back in 2008.
 
That's some good research there...

You don't happen to have a spare PSU or GPU you can try do you? This should give you an answer...

I don't think there is an easy way. Software that monitors VRM temps may show some voltage info, but what you really need is to monitor the actual 12v input into the graphics card.

I would just get another PSU. You should know that if and when a PSU fails completely it can take out components in the computer. My point is you should change it ASAP. Modern PSU's are more power efficient and quieter than the old ones anyway.

One more thing don't consider anything less than 700 watts IMHO (even for one card). Its worth the extra £10 to not over stress the PSU.

You can buy a PSU tester. I bought one ages ago from Muppetlins for about a tenner and its proved invaluable for testing PSU's and for watercooling to plug the ATX cable into when testing the loop for leaks. Several times tested a PSU to find its okay and it was the motherboard at fault.
 
Thank's for the replies, I think I'll just get a new PSU then for the time being as I'm actually planning on building a whole new system once Haswell arrives.

Any recommendations what PSU to get for my system?
