I'm currently building a gaming PC and I don't really know how much power I need. I would love the help. Also if you had comments on any part of my build (a gpu that is cheaper but is very similar or if the parts wouldn't work together) Thanks!

CPU: AMD FD8320FRHKBOX FX-8320 FX-Series 8-Core Black Edition

GPU: XFXAMD Radeon HD 7870 2GB

Memory: Corsair Vengeance 8 GB

Hard Drive: Western Digital 1TB WD Caviar Blue 3.5" SATA Desktop Internal Hard Drive

Mother Board: MSI LGA1155/Intel B75/DDR3/SATA3 USB 3.0/A&GbE/MicroATX Motherboard B75MA-P45

Tell me which one is better for my current build for the cases.

Thanks!

For me, I always go with more than I actually need, I have a 800w PSU, but my PC even at load probably uses about 400-500, if that. For that specific system, id personally go with 550-650.

Here's a couple to choose from.

Corsair CX600 15% off:

Corsair CX600 (Modular) 15% off:

OCZ ModXStream 700W 15% off and $30 rebate:
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

And as far as cases, I'd go with the NZXT one. Personally because it will have more room. If thats your price limit, id look into the Antec 300. IMO I love antec cases, all I've ever owned.

Hi
A decent, branded (like Corsair) 500W PSU should be fine. Make sure it has at least a bronze efficiency rating. I wouldn't spend less than £45 on a PSU.
Hope this helps :)
