As the title says, I am currently selecting a PSU to use for my new build. You can see the details for this build here: Budget AM3+ for Office and Light Gaming
I designed by rig so that it's inexpensive now, but can have more components added as time goes on. Starting out, I will have use a HD 7750 GPU, 8 GB of RAM, and a 965 BE CPU. I plan to have a final build using a 7770 or 7750 crossfired with the original GPU, 16 GB of RAM, and a late model Bulldozer/FX CPU.
Entering the info into the OuterVision and NewEgg PSU calculators yielded the following information:
New Build:
OuterVision minimum: 334 watts
NewEgg recommended: 354 watts
OuterVision recommended: 384 watts
Final Build:
OuterVision minimum: 445 watts
NewEgg recommended: 491 watts
OuterVision recommended: 495 watts
So assuming the margin of error used in the recommended values is sufficient, looks like I should be good to go with a 500 watt unit, eh?
Obviously everyone wants a reliable unit for the best price, but I'm also interested on saving on the electricity bill, so 80 PLUS certification is a requirement, though it seems most are nowadays, anyway. As far as particular PSU models are concerned, I discovered this list of recommended units: A list of recommended PSUs
So here are the three primary contenders, in $$$ order:
1) Rosewill RG530 S12
ATNG made. 41 amps 12V. $49.99 and 2 year warranty ($25.00/year). (Regular) 80 PLUS.
2) Antec Neo Eco 520C
Seasonic made. 40 amps 12V power. $54.99 and 3 yr warranty ($18.33/year). (Regular) 80 PLUS.
3) Seasonic 520W S12II
Seasonic. 40A. $67.99 and 5 year warranty ($13.60/year). 80 PLUS Bronze.
So is there that much difference between regular 80 PLUS and Bronze, in terms of utility bill savings? From what I've read (briefly), it seems there isn't; the power savings is mostly seen in a large-scale corporate setting. I think the primary benefit of the increasingly expensive units is the extension of warranty, especially the 5-year on the Seasonic. In terms of per-year warranty value, the Seasonic is actually the cheapest!
Any comments/suggestions? This is my first build and I'd like to do it right the first time. Thanks!
