^This is really nice RAM for your system, but the low latency will go to waste if you can't configure the timings in the BIOS. I'd check the BIOS for any mention of memory timings or XMP, and if those settings are absent, go for this: http://www.newegg.com/Product/Product.aspx?Item=N82E16820226404
Regarding the PSU, you'll need a 430W PSU at the ABSOLUTE MINIMUM, and I'd go 500W just to be safe. Something like this will make your system efficient and clean-looking: http://pcpartpicker.com/mr/newegg/rosewill-power-supply-quark550 If that's too much money, this one's a lot cheaper: http://pcpartpicker.com/mr/newegg/corsair-power-supply-cx600m
