I plan on purchasing a case and PSU for christmas (I figure it's a good idea to wait to purchase the rest of the system at once, so the hardware is all up to date). I've decided on the HAF 912 for the case, but I am a little confused on just how many watts are going to be enough for the PSU. I think there are going to be some cpu/gpu refreshes early next year, so obviously the hardware will change, but the type of stuff I'm looking at now is the AMD Phenom II X4 955/965 and probably a Geforce GTX 460. Again, hardware will change, but that's the level that I'm looking at. I also don't plan on SLI/Crossfire in the future. The specific 520W PSU I was looking at was this one: http://www.newegg.com/Product/Product.aspx?Item=N82E168... Since this will be a gift, I don't want to ask for way more than I'll ever need.
