a quality 550w+ (43a+ on the 12v rail) will be more then enough, you will be around 350w total system power while gaming

Core i7 Test System Specs
- Intel Core i7-3960X Extreme Edition (3.30GHz)
- x4 2GB G.Skill DDR3-1600(CAS 8-8-8-20)
- Gigabyte G1.Assassin2 (Intel X79)

First, newer components take less power than older ones, so you don't need as much power as you might think.

Second, by quality brand ct meant something like corsair, seasonic, or antec. Alpine is not a quality brand. Look for a powers supply that is 80plus (bronze, silver, gold, or platinum) certified.

550w should be enough, but you could get a little more if you're overclocking.

because a quality 550w PSU will offer 550w continuously and peak above that mark and a cheap 550w unit will basically call it quits at 325w like yours did since with those specs, your probably never broke 325w.


for $50, you won't find a better PSU

AX is most efficient, then HX, then TX. After that, probably GS and CX.
