So here is the build I am going to make:
Seagate Barracuda 1TB 64MB Cache: 67.99
Corsair Vengeance 4GB(1x4)DDR3 1600mhz RAM: 44.99
GIGABYTE GA-B85M-D3H LGA 1150 Intel B85 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard: 89.99
Intel i5 4670 3.4ghz: 229.99
Cougar Spike Micro-ATX Case: 39.99

467 dollars overall.
I need recommendations on a stable, good quality PSU for under 80 dollars. I will eventually be adding a GTX 660 and another 4GB of RAM, and don't want to have to upgrade to another PSU

Thank you!
PS. Any other suggestions you can make that will lower the price but keep the performance would be very helpful, but please don't increase the price.
I need to keep the build under 630 dollars. I will be playing games like Skyrim and Far Cry 3, and Maybe some Planetside 2.
