Options:
a. try to fit a second PSU to bottom of your PC-P80

b. sell your 1200W and buy a 1500W

c. keep the 1200W to power 3 GTX580s and buy Thermaltake Power Express 650W to power the 4th GTX580. This will occupy two 5.25'' drive bays.

This unit is perhaps only a slightly above average unit but it will get the job done.

Runs fine without any problems.

My current cpu cooling on its own, draws 100w.
You got any idea how much power that is using?
Im really confused from the mix of awnsers, from what I have read its enough but not if im Overclocking everything. So I should use the 1200W for the cards and Another for the system? what would I need for just the system but with a 990X/980X?

A good 1200w+ PSU will be enough with OCing room.

Mine, without OCing the 580s, draws about 1000w from the wall (give or take, peak was about 1100w) while doing some benchmarks.

This means that the system is taking about 850-900w (give or take).

Furmark / OCCT will require another 40-50w per card over that.

So there is plenty of room.


I'm going to use a second PSU in my current build, mainly because it has 14 fans, 2 pumps and lots of other stuff in the system, and since I'm having another gtx 470 for physx on that system.

So do you think mine is good enough? I did plan on using my current VGA card as a physx card as well. Oh and a 980X/990X at high volts instead of my current chip. I have a Swiftech MCP655 Pump as well if that helps.

The 430 barely takes any power from the system, even when at work as a physx card. There will be no reason to overclock it, and it will barely go 40-50% usage.

So in my opinion, you should be fine.

I have seen reviews of the antec 1200w you have, and its a great PSU. So you should be fine.

1500W I would say only if you plan going nuts with OCing and trying to break some records under water. But even than, I think the antec can handle it. Its a tough bastered.

When are you looking at doing this? What case ate you using? I'm very curious. I must say that I LOVE this forum. I can find others that share my complete disregard to rational behavior as well

Try your Antec first. With AMD the consumption should be a little less than the 580s. You also only have two HDDs, so that's allowing for more room for another GPU.

Doesn't the HCP-1200 PSU have the ability to output 1700~ watts?
I would say go for that.
