So I'm currently in the process of upgrading my GPU and Ram and bought a Radeon 7870 and 8Gb's of ddr3. I didn't think I would need a new PSU but using this ASUS PSU calculator on their website they estimated that I need like 550W+ So being that I have about $100 or so to spend I thought I'd just upgrade it as well.
So looking for suggestions on good PSU's around the $100 range can go a bit higher $130 if it's really worth it. 600W-750W is what I'm interested in. Thanks.
