Well, thanks for the correction...I knew I stated the facts incorrectly. lol.

Like Phaedrus has pointed out - a 1200W PSU should be enough.

But ....

with the kind of power you have in this system, 1200 is cutting it a bit close and with the temptation (for me anyway) to continue upgrading, a 1500 watt PSU makes more and more sense.

Take a look at the Silverstone 1500 watt PSU - it is very close in cost to the best 1200 watt PSUs and it is of good quality as well.

Hey man I know you have posted in here already but What do you personally think, like would you use just my one PSU or would you get two?

I am sure some members had posted 3/4 ways GTX580 SLI already. Here is one of them shown the scaling of 2/3/4 ways 580 SLI
post #35 of 39
This is what i call spending money... why you need 4 GTX 580? 2 in SLI is more then enough... with the rest of the money get a 980x and sell your w3520 and you would still have money to spare...

Either way on topic, get a Silverstone Strider 1500w or a Antec HCP1200

Don't bother using two power supplies. Just not worth the hassle.

The TPQ-1200OC should *probably* handle your needs. If it can't quite do it it will just shut down, no harm done. If you want to upgrade, the HCP-1200 should be capable of doing what you need.

Thanks mate, Whats better about that PSU?

I though that at the start of this review(second paragraph) they were saying the TPQ was more powerful then the HCP?

The second paragraph is talking about something completely different; and besides, the +12V OCP trip points actually turned out higher than the TPQ's anyway.

What makes it better is that the HCP-1200 can do 1500WDC+ without modification, while the TPQ-1200OC can do about 1350WDC without modification. Plus the HCP is a better performer and has higher efficiency.
