Hello, I'm building a computer for gaming (Not high end, just decent) on a budget of approximately $1000. This is the first computer I'm building so I'm quite new to this. I have selected most of the parts online, but have not ordered any of them yet, so nothing is set in stone. I was wondering if anyone had some suggestions for a power supply to fit my current build. I used an online calculator (http://support.asus.com/PowerSupply.aspx?SLanguage=en) and it said I would need roughly 500W.
Parts I want to get so far:
Mobo: Asus M5A99X EVO R2.0 AM3+ Motherboard
CPU: AMD FX-6300 Six-Core (or possibly the FX-4300)
GPU: Radeon HD 7850 Core Edition 2GB
Memory: 8GB DDR3 (2x 4GB) Crucial Ballistix
Hard Drive: WD Blue 500GB 7200RPM
and a cheap samsung DvD drive.
So far I've read that I should buy a good brand PSU like Corsair, but idk which one. Also I've heard that I should go for a good efficiency rating of at least 80+ silver, is that necessary?
Also, any critiques or advice on my chosen parts is very welcome. I would like to have some second or third opinions on my parts as, like I said ,I am new to building a computer. Thank you a lot!
(P.S I live in canada so I do most of my online shopping from tigerdirect, newegg, etc.)
