My GTX 480 using too much watts?

post #1 of 23
Thread Starter 
I have my GTX 480 overclocked @ 1.114V, So I just ran Furmark with all the setting's high, and the watt monitor which I have my computer plugged into was using about 587 watts,

I then started up Prime 95 as well.... then it shot all the way upto 787 watts with furmark and Prime95 running together... And I only have a 700 Watt PSU lol.

If I remove the overvolt, it will be fine becuase it will only take up around 600 watts.... around by that with the same setting's

787 x 0.80 = 630

You're computers using 630w while pulling 787w from the wall, you should be fine.

What's your 480 clocked at?

My 480 running at 960 when running furmark in windowed mode pulls around 600-650W from the wall.

Try running furmark in windowed mode for some reason it pulls more power. Don't be suprised if you PSU trips on OC

Indeed, if you assume your PSU is 80% efficient and you are drawing 787W from the wall then as rocstar points out the PSU is providing around 630W for your components.

Bear in mind that Silent Pro 700W is actually more like a 600W so you're probably right there around the limit of where you want to be.

It was a 840/1680/1904 @ 1.114V, I just reverted the voltage back to stock and put the clocks back too 800MHz, and it cuts about 60 watts off.

The watt monitor which I have my computer plugged in to says that my computer is idleing at 154Watts, and with furmark at the highest settings + Prime 95 streesing my CPU out and memory, it uses about 697 watts, but If I overvolt my GPU it will use about 767 watts.

And I only have a 700W PSU

Thats about right then. It's the worst possible scenario though. You won't see that during normal gaming i wouldn't of thought!

Nope, v'e tried out a few games now, and my watt monitor only shows that I'm using around 300-330 watts, even in Crysis maxed out as well.
