With a nice single 12v rail you dont have to worry about splitting the load and wasting an entire rail on the CPU, instead with a single 12v rail psu all the power goes to the components that need it the most.



I just got home and tested my box with a Kill-A-Watt,

Total system power: 140w -160w idle, and 250w-300w in game.

After doing more research on power supplies, I have to agree with you that a single 12v with 40+ amps would be ideal, but doesn't my current power usage seem a bit on the low side?

If it is really necessary, I would certainly buy another PSU, however I wanted to keep this upgrade cheap as possible since my next upgrade will be an entirely new system.


Here are my real system specifications:

Core 2 Duo E6420 (65w) @ 2.6 ghz
4GB XMMS2 DDR2 800
2x 7200 RPM drives
1x DVD-RW

gtx 260 55nm 216core @stock.oc

2x92mm fan
1x80mm fan
(I'm guessing these fans are between 5w-15w each?)
