I'm interested in overclocking my Q6600 to around 3.0Ghz, but I don't know much about the power consumption of my hardware, nor how accurate those PSU calculators are....so I'm basically concerned about whether or not my PSU will provide enough power to support my current hardware once my CPU is overclocked.
Currently, I'm using:
CPU: Q6600 with a Noctua NH-U9B heatsink
GPU: Gigabyte 4850 1Gb, factory overclocked to 700Mhz
RAM: 2x2Gb DDR2 RAM
Fans: 3x120mm fan, 1x140mm LED Fan, 1x80mm CPU heatsink fan, 1x210mm LED fan
HDD: 1xIDE, 2xSATA
I see where you would be apprehensive. But IME, gigabyte products OC very well. I have a GA-P35-DS3L with a Q6600 (Acrtic Freezer Pro 7), 4 x 1 GB of g.skill 800, and a 600W PSU @ 3.6ghz, 400 x 9. 1.4V, 1600FSB. Ram is at 1000mhz from 800 stock 5-5-5-15. Only thing I need is a friggin gtx280, to upgrade my 8800gts640.
