I was wondering how much watts my power supply will need to fire up 2 gtx 460's in sli

do you think this PSU will do it?

@noorerino, that's really a very poor choice of PSU, which is the most important part of a PC.

I would personally go with one of these for the same price.

these units would need to use adapters (only two power connections with the unit) but will still work

I would personally go with the XFX unless you don't like the green.


here is a review of the Kingwin 1000w PSU, I would expect a similar performance from the 700w (both are made by Superflower). I found a review of the older Kingwin 700w and they stated solid power but inefficient past a certain point. Looks like the new versions fixed some of those issues. In short, yes the Kingwin will work. If it was my choice, I would still go with the XFX or Antec from above.

Summary

Kingwin's first attempt at an 80 Plus Gold unit is a pretty good effort. However, it seems that Kingwin has once again gone and let a few performance related items slip and slide in order to get those wonderful Gold numbers. As it stands now, this unit is an improvement on the previous generation Lazer model. I just wish that improvement had been more substantial. Another good, but not great, unit from Kingwin.

The Good:

* more efficient than the last Lazer
* gobs of 12V power
* managed full power at 6 degrees over rated operating temperature
* good voltage regulation
* quiet

The Bad:

* minor rails a little rippletastic... again...

The Mediocre:

* gets a little warm for an 80 Plus Gold unit

Why is everyone hating on Kingwin? I got a Kingwin Lazer 850W for a hot hundred and it runs perfectly fine. Personally, I'll put it above XFX and Seasonic and under Antec. Corsair is on a level of their own. I think that Kingwin you picked out will be completely fine and more than enough like CT said. If you wanna play it safe, look at nothing else but Corsair PSUs and don't even consider anything else.

Check out this power supply diagnostics.

It shines a whole new light on the subject. The high end computer he used didn't have dual graphics, but one more gpu isn't going to drop another 150w+ on top of the 500w he showed. So a 650w PSU should be plenty as long as it's not a cheap POS.

These guys selling 1000W PSUs just want you to think you need em, so you'll pay the extra cash
