A good quality 850 watts psu would do it.
SLI with GTX 480 is insane. Sell them and buy a GTX 690 or two GTX 670's.
At the very least, assuming you don't have 8 hdds with 6 fans or something. I would prefer a solid 1000 watts to give some room. And if you wish to do record oc on all 3 components then even a 1000w will be used up fully.
Well my current 630w psu is not enough so do I sell it and get an 850w psu or do I sell both my 480s and my spare 460 to buy a 670?
no, YOU are giving some bad advice. just stock gtx480 sli can pull 500 watts or more just for the cards alone. a 650 watt psu is not very sufficient to power 480 sli at all. a 750 watt is not sufficient to power that system overclocked unless you want the psu working extremely hard when gaming. every review out there will recommend an 850 watt psu for a system like that to have plenty of room.Thats extremely false information. I have a 2500K which uses more power and SLI GTX 470 which uses 35 less watts than a GTX 480 per card and I can OC everything to its maximum and over volt it to the limit with 6 HDD's (4 being Vraptors) and still have room left over.
@OP A nice 750w will be great for OCing, and a 650w will be fine for stock/mild OCing. Just make sure to get high quality units.
If you are out right buying a new PSU to accommodate the 480 SLI, get something with some headroom.
I would get at a minimum a 1000W or 1200W PSU. You can run it on an 850W, but your PSU will be operating near its capacity. That is not good for your PSU's longevity, noise levels of the PSU's fan or your system in general and its future upgrades. The price difference between an 800W and 1000W is minimal, better to get something big now that will be able to attend to something you might run in the future as well. PSU is like your monitor where you can buy something nice and not have a need to upgrade it again.
Get a 1K or 1.2K PSU now and don't worry about PSU issues or operating your PSU near its threshold again in the future.
Just my 2c. I used to run 480 tri-sli and got the PSU I have now for the same reason. Now I think I am probably using a little over a 1/3 of its capacity though

GTX480s in SLI?
You might want to consider getting some solar panels for your house...^_^
How much power do I need to run two gtx 480s in SLI with an i5-3570k? I also have two hard drives connected.
My current PSU is 630w.
Alright so I think I will keep the 480s and do SLI then pick up a PSU somewhere in the 800-1000w range. Thanks for all the advice!
Edit: Budget for PSU is around $150.
