PSU recommendation for this build.

post #1 of 12
Thread Starter 
I'm building a computer for a friend and I've used 2 different power supply calculators online and I'm getting a 700 watt result as well as a 480 watt result from those 2 sites....so I'm naturally confused. here is what the build will look like:

i5 750
EVGA P55 SLI E655
2x Corsair 4GB DDR3 1600Mhz (CMX4GX3M2A1600C9)
2x SLI GALAXY GeForce GTX 460 GC
500GB 7200 rpm HD
Creative X Fi Gamer
DVD RW optical
Cooler Master Elite 310 RC-310-BWN1-GP case.

I'm in love with my Corsair HX750.
I've been using it about a year now. I have loads of USB devices 12 ports normally full and never an issue. as well as 4 HDD's and an SSD, I also had 2x 5850's and 8gb of ram and 2x64gb SSD's when I initially built this system...never an issue.

Its not what I have now, had to downgrade last summer for a trip I wanted to go on lol

At least the calculators didn't say 2.21GW.

Well, I think it's safe to say that ~700W is better when going SLI than 480W. I would aim for 600+ watt for sure.

A good 650W would be perfectly adequate for that system.

You can ignore calculators as they generally overrate the amount of watts you need. 600-650w is fine for two GTX 460's.

My budget is spoiled! I saw someone sell their 620HX for $50 and I'm expecting the same deal lol...but I'm looking for a good quality PSU ranging from $40-$75.

You can buy from people by PMing them.
You only need rep to sell.
I wouldn't recommend used PSU's though, makes me feel iffy.
But that's just me.
