Graphics card PSU problem?

[dorgoo]

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.

Unfortunately i don't, is there a way i can test to see if my PSU is working correctly do you think?

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?
