+3.3V 30A
+5V 38A
+12V1 22A
+12V2 22A
-5V -
-12V 0.6A
+5VSB 3A

you have 22A on both 12v rails you should be fine on juice

I'm about out of ideas other than, like I said at the beginning, Heat causing it

its just very odd since the card should alert me if its getting too hot, hmmm. well thanks for all the help.

assuming for a second that the card is broken which out of these 2 do you think would be a decent replacement (which is better and are they better then my current card?) thanks alot

Look under the nVidia settings

Display Props>settings>advanced>nvidia>temps

yeah ive been doing that, at the moment its at 65C but says it should not experience any slowdown untill 115C

it also has a checked box for "notify me when this temp exceeds this threshold"
which it NEVER has making me think it has never got that hot?

 

[Blind Dragon]

When you put in under full load though the Temp will go up, i was curious how high it gets -> since your problem happens after gaming for a bit

 

[Narey]

ill play a game and as soon as the message comes up ill check the temperature, hold on..

 

[Narey]

ok i went on world of warcraft and ran about like a maniac, the temperature kept going up, last time i checked it was at 91 then the power problems popped up

 

[Narey]

i have just found that i have a molex to 6 pin gpu plug in my psu box, ive plugged this into a completely free chain which now only plowers the GPU, before 1 of the molexs connected was also powering everything else (althoguh the GPU was at the top)

 

[Narey]

if anything that made it worse, sorry for the huge line of posts

 

[Blind Dragon]

Does your case have a lot of fans on it?

 

[Narey]

i have no fans apart from the ones in the psu, gpu and ofcourse cpu
(i do have what is supposed to be the best cpu fan, Zalman 9700LED)

 

[Blind Dragon]

I would try removing the case cover and gaming to see if it still faults, if not you may just need a new case that can dissipate the heat

 

[Narey]

i uninstalled all drivers and installed some differnt drivers i havent used before from the nvidia site, i then found some updates for my motherboard

ran the nvidia stress test on the card for 10 mins, was fine. played WoW for about 40 mins and it was fine. however the card was reaching about 90C but there were no complaints

for the first time in about a month i wasnt inturrupted by that power indicator message. is the problem solved? is 90C to hot?

 

[Blind Dragon]

you shouldn't see problems until 110-115

 

[Narey]

ah ok cool ill see what happens, out of intrest is it possible to remove/clean/apply new termal greece the fan?
