I am building a new computer and would like to double check on the power supply. I am using Building a PC, Part VI: Rebuilding as a guideline, updating parts to newer ones available, but am staying within the lines so to speak (aside from the GPUs).
Overall this will be a gaming rig with 2 x 6870s in crossfire, 4x2 DDR3 DIMMS, i7, etc. (I am still looking into water cooling units and don't know how that will impact psu requirements.)
I have churned the expected setup though the psu calcs on newegg, outervision, and used ibuypower as a reference point. These break down as:
- outervision - 501W
- newegg - 780W
- ibuypower - 850W
I understand these are approximations/best guesses. Based on the Jeff's article above and the reviews on newegg I believe I am going to go with the CORSAIR HX Series (approximate current prices):
- 650W - $120
- 750W - $140
- 850W - $170
- 1000W - $230
It's probably silly to even be concerned about going up to the 850W at this point based on what I want to do with the box. Should I even be looking at the 1000W or is that just totally unnecessary? (not that that's a bad thing)
I am really enjoying this process and appreciate input, thanks.
