Hey guys,

One of my friends at work is upgrading his gaming system (he was previously running 3 GeForce 9800 GTX+) and he decided to give me two of them. My current system is very antiquated (got it about 6 years ago) so I'm completely building a new system. I'll list the components that I have priced right now (and if anyone has any comments on any of them, feel free to let me know) but my biggest question is how much power do I need? I read somewhere that to run two 9800 GTX+ in SLI, the minimum is 750W but I wanted to know for this particular system: (Sorry, just felt like copy/paste from Newegg)

Case: XCLIO A380BK Fully Black SECC 1.0mm thickness ATX Full Tower Computer Case
Mobo: MSI NF750-G55 AM3 NVIDIA nForce 750a SLI HDMI ATX AMD Motherboard
CPU: AMD Phenom II X4 955 Black Edition Deneb 3.2GHz Socket AM3 125W Quad-Core Processor
RAM: A-DATA 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Dual Channel Kit Desktop Memory
GPU: 2 nVidia GeForce 9800 GTX+ (SLI)
PSU: Antec EarthWatts EA750 750W Continuous Power ATX12V version 2.3 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC ...

If anyone can help with this, it would be greatly appreciated.

That Antec Earthwatts PSU will be perfect, its a great PSU and gives you the headroom for an OC and GPU upgrade in the future.

In this same system, I was wondering what would be a good CPU fan/heatsink, or if I need one (I don't ever overclock)? I've homebuilt systems before, but have always got my performance-intensive machines prebuilt (Cyberpower) but thought I'd try this time

You don't need an aftermarket cooler if you're not overclocking. The stock cooler works just fine with a stock speed CPU. That's what the cooler was designed to do. :)
