Right, but your box is overloaded with SLI this and watercooling that. 1k PSU's are being advised for single GTX boxes on air.
Besides, you run 580 max. Peaking at what? Anywhere near 1k?
Edit: Don't mean to argue, but I'm now understanding the need for 1k, and your response didn't straighten anything out. Just the opposite infact. Unless wattage usage in our PC's are akin to AVR's and speaker loads?
580watts is the max my PC ever used under any circumstances, even startup. Anyone advising 1kw PSUs for single 8800GTX boxes and dual core CPUs on air cooling is a fool. I bought my power supply mainly because it was a quality unit and I knew it would be capable of handling any expansion needs over the next couple of years. Mainly though I bought it because it was a quality, part. Needing that much power had nothing to do with it.
