The whole "Wattage" craze is ridiculous. Unless you're rocking SLI setups with two GTX690s (or the Radeon equivalent) that require two 6 pin connectors each, and have 9 drives running besides, you will never need more than 500/550 W in your PSU.

My current rig has a 500W PSU and it runs just fine. 2 SSDs, one data drive, one DVD drive, GTX660ti, i-2500K.

Well, it is an old one from my former Windows XP Pro. SP3 machine. I decided to get a new one since my old Debian/Linux's PSU was crap (Antec) -- making noises already within a year. for my current computer setups.

Yeah, it's true you usually don't need more than 500 watts, especially if you get a high-end PS. Also, newer procs on smaller processes use less power than before. But for cheap power supplies, the rating can be exaggerated, or with cheap components can lose its ability to handle higher wattages as it heats up. I picked up 800 or so b/c I was anticipating 8800 Ultras in SLI with an overclocked core 2 quad proc, which was 500 watts for those parts alone. I agree that you don't need it, but it's good to have overhead if you're planning on going SLI.

And don't forget that an 800 watt PS doesn't use any more power than a 500 watt PS with the same PC parts.
