What Power Supply Should I Buy?

Ok so I'm building a computer for my school, basically just for things like browsing the web, using Microsoft Office, and doing research and what not. I've got basically everything except the power supply. Here's what I've got
1. Gigabyte 880GMA-UD2H Motherboard
2. AMD Athlon II X2 255 Regor 3.1GHz 2 x 1MB L2 Cache Socket AM3 65W Dual-Core Desktop Processor
3. Western Digital 500 GB SATA OEM Desktop Hard Drive WD5000AADS (Caviar Green)
4. CORSAIR XMS3 DHX 4GB ( 2 X 2GB ) PC3-10666 1333MHz 240-pin DDR3 CL9 Dual Channel Desktop Memory Kit
5. NZXT Alpha Black Steel ATX Mid Tower Computer Case

Would all these put together work ok? What power supply should I buy for this?

To take from my previous post in your other thread:

I would suggest this: Newegg.com - Thermaltake TR2 W0070RUC 430W ATX12V V2.2 Intel Core i7 Compliant Dual 80mm Fans Full Cable Sleevings Power Supply. If you're just going to use the onboard video with the onboard audio, a hard drive and DVD Drive, then this should suffice. It runs decently, I've installed it on many PCs and it definitely lasts quite a good while. Still haven't had one go out on me in over 3 years, which is not bad.

If you plan to upgrade to higher end components some time, you might look into getting a higher end power supply such as: http://www.newegg.com/Product/Produc...82E16817182070

This is a cool little tool and you can load up some mods to see if your purchase will hold up over time !
I just moved from a 600w to 1050 for making the too little mistake !

If you are on a budget:

Newegg.com - Antec earthwatts EA430 430W Continuous Power ATX12V v2.0 80 PLUS Certified Active PFC Power Supply

Newegg.com - CORSAIR Builder Series CX430 CMPSU-430CX 430W ATX12V Active PFC Power Supply

Newegg.com - Thermaltake TR2 W0070RUC 430W ATX12V V2.2 Intel Core i7 Compliant Dual 80mm Fans Full Cable Sleevings Power Supply

If you are free to spend some money on a higher rated supply to give yourself room for upgrades in the future:

Newegg.com - Antec EarthWatts EA650 650W Continuous Power ATX12V Ver.2.2 / EPS12V version 2.91 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC "compatible with Core i7/Core i5" Power Supply

Newegg.com - CORSAIR Builder Series CMPSU-600CX 600W ATX12V v2.3 Active PFC Power Supply

Newegg.com - SIGMA MONSTER SP650C 650W Continuous @ 40°C ATX12V 2.2V / EPS12V 2.91 SLI Ready CrossFire Ready Modular Active PFC Power Supply


To answer your other question, those components should work fine together. There should be a compatibility list available for the motherboard, if you want to be super sure that your components will mesh.
