Enough wattage?!

post #1 of 8
Thread Starter 
Alright, so third GTX580 3072 coming in. i7 2600, basically the rig below.

So I just tried a basic wattage calculator, and right now my corsair AX1200 can only do 1200. Do I need a second PSU, since the calculator says 1258 for 3 GTX's and the rest... And if I want to buy a dedicated Physx card, will I really need another PSU?!

My brother got almost the same rig as you. He's pulling 3x 580s and his cpu is oc to 4.8 running on the Ax 1200w without a problem. You don't need a physx card. The 580s crush anything in their path. Only way you'll get something with a physx card maybe if you go with a 570 as one which equals waste. All that extra power and heat for a couple of fps? Nah that's not worth it

You could run that setup on a solid 1000w unit, so don't worry about it.

Hell even a solid 850w correct? Like a seasonic x850?

Nah, you're good. You have a solid PSU, predicted wattage accounts for low-end units. You could probably handle that setup with a nice 1000W, I wouldn't worry about it.

For tripple SLi + some heavy overclocks, you'd want a 950w-1000w unit.

For the most part, there's only a handful of good 900-999w units. So a 1000w is just a better option. More so since most 900-950w units are not modular.
