I've got a new rig coming up, and I was wondering what a good size PSU would be. I'm two-way SLI-ing the GPU, and I think I want enough headroom that I could go back and put in a third if I ever got to that point. Here's the build thus far:
COOLER MASTER HAF X RC-942-KKN1 Black Steel/ Plastic ATX Full Tower Computer Case
ASUS P8Z68-V PRO LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard
EVGA 012-P3-1571-KR GeForce GTX 570 HD w/Display-Port (Fermi) 1280MB 320-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card
Intel Core i7-2600K Sandy Bridge 3.4GHz (3.8GHz Turbo Boost) LGA 1155 95W Quad-Core Desktop Processor
Intel 510 Series (Elm Crest) SSDSC2MH120A2K5 2.5" 120GB SATA III MLC Internal Solid State Drive (SSD)
G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
Seagate Barracuda ST31000524AS 1TB 7200 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive
I'm still missing (in addition to the PSU, obviously), a keyboard/mouse, a monitor, and a DVD drive, but that last one's cheap and easy to pick up in person at the local Frys, and I'd rather shop for the peripherals in person anyways (unless I see a good deal on newegg or something).
This is my first build, though, so if there's any glaring mistakes like parts not being compatible or some crap, please for the love of circuitry, point them out. Feel free to be as condescending and mightier-than-thou as you want, as long as I can learn from it. :D
