I've had pretty good luck with the corsair power supplies. i've bought...about 20 of em...none failed (unless struck by lightening). ASRock is ok, but i also like gigabyte mb's and noticed at least one for a similar price.

I'm using a cx600 corsair...cheap basic but reliable; there is also a cheap 600w evga that has good reviews. I like the processor (but get an i5 if you can afford it).
If you want a cheap/free idea for win7, send me a message. That ssd really can make a difference.
I have a similar build but with an older i7 2600, ati sapphire 380 4gb, HAF 912 coolermaster case, 8gb ddr3 gskill ram and 240gb ssd, 1tb storage, 600w cx600 psu and a asus P8B75-M/CSM
motherboard.
