Unlike newer hardware, you're going to be pushing that 800w psu, the 480's are power hungry. That being said, at stock settings a quality 800w PSU will be fine.

I think it's going to be enough, but this isn't that great of a PSU.

Regarding the power consumption: http://www.guru3d.com/articles_pages/geforce_gtx_480_3_way_sli_review,25.html

With two GTX 480s under full load in their system, their PSU pulled 702W from the wall outlet. Their CPU was idling, so I have to add about 100-150W for your CPU under full load which make the PSU pulling 852W. This means that if the PSU is 85% efficient while pulling 852W from the wall outlet, then the computer is pulling 725W from the PSU. The gaming power draw will be even lower at around 600-700W.

Now, this PSU is really just a fairly decent 750W PSU because its +12V capacity is only 720W. So, you're getting the right capacity, but you're able to do a lot better in terms of quality. What store are you ordering this from?

I'm trying to keep mine alive as well, best of luck!

My 470s were so power hungry, I just decided to get rid of them (3 year warranty was almost done) and got 660s in return; I was surprised they take up half the power consumption of the 470s.

In your situation, it seems like your PSU will be "alright" for the task. Best of luck!

Oh, ok cool. Just don't overclock the 480s, and I'd even keep the overclocking a bit light on the CPU. I don't know how good this PSU is nor do I know how good the quality of its power delivery is. Although, it should have enough power even though your gaming power draw will be around 600-700W depending on the game.

800mhz core with 2000 memory at 1024mv or 1037mv will be a great boost to FPS in all games, and will not overburden your PSU (so long as the cards can OC normally)

Never had a 480 not do the above OC with one of the 2 voltages i mentioned, and i have owned 3.

@TwoCables, thanks for all the info, greatly appreciated.

@amd655, cool, I'll might give it a try

Both cards are reference cards by ASUS.

You're welcome.

I'm still not sure if this PSU should be trusted with overclocking. It's not the capacity I'm worried about (although, we're already looking at 600-700W while gaming with the 480s at stock), but it's the PSUs general quality. The Newton R2 isn't even on OCN's list of recommended PSUs: http://www.overclock.net/t/183810/faq-recommended-power-supplies The Newton R3 and the Tesla R2 series PSUs are, but not the Newton R2. To me, that says "don't trust this PSU with overclocking or even with a high-end system". That's just my take on it.

The Newton R2 is an older ATNG made unit thats been discontinued think its not on the list as its both old and rare

But if i recall right it was not all that bad

Oh, that explains its plain 80+ Certification. Back then, there were some pretty decent PSUs that had that rating. Although, I would guess that they're not as good by today's standards.
