I'm building my first computer in a long time, and I'm wondering which PSU I should purchase. I was initially thinking that I should purchase a psu with a wattage over what I would use for the gtx 470 sli (for whatever gpus I buy in the future), but it seems that new gpus need less and less power and are more and more efficient.

I do plan on overclocking to ~4.3 with my hyper 212, so I'd like decent voltage regulation, but it seems that the highly regarded corsairs and seasonics are just so damn expensive - I don't feel like spending half the money on a build on the psu.

Any hints on a good psu for me?

Thanks!

Don't buy that Antec. I have had a few people coming through here and know others with Antec power supplies that have multi 12v rails and have nothing but issues with their rigs.. If you want a good Power Supply don't see how cheap you can go.. Actually a power supply is like your computer insurance policy. The better the power supply is the better your rig is powered or holds up.

You beat me :kaola: I was about to recommend the same psu.
 
Well i didn't know you had a microcenter near by, but that psu won't be better than those 2, it has the same amps.
You won't find any cheaper than those suggested, only if you want raidmax or crappy brands alike that will shutdow or throttle the system.

Well SLI 470 needs ~400W

So

~400W GPU
~16W Ram
~77W CPU
~15W Hdd
~25W DVD

~533W

So add some oc and the 650W will suffice you.

Lets say you go crazy :p and add another 470

That will need ~580W (3x)

533+180=713W A good 750 W will suffice you.

XFX 650W Pro Core delivering up to 815W if you want only 2 way.

XFX 750 W Pro Core delivering up to 930W if you want 3 way.

IMO that 650W would do the job.
