Ok it's good to know that PSU would work without a dedicated GPU card. What if I want to add ATI Radeon HD 4830 later on? would I then have to move up? What would be the desired PSU wattage in that case?
You guys are all giving some great advice to a noob here. I read somewhere that number of rails can make a difference. With my set up (including the future purchase, ATI Radeon HD 4830), am I better off going with single rail 12V or multiple rails? I am confused even after I read it. There doesn't seem to be a "set" way to tell which way to go... Specifically, I am looking to replace the stock 420W PSU with this one.
A 300 will be fine. With no graphics card you really could get by with about 250 but 300 would be better. Though if you are planning on adding a video card you need to get a bigger PSU to prepare your system.
None of those look very good though. IIRC, Seasonic makes some PSUs that fit microATX.
From what I can see their max Watt is around 300W. If I were to play 3D games in the future, wouldn't I need something bigger? I was looking at the recommended PSU for ATI Radeon HD 4830, it says 550W in crossfire, 450W single. I can probably get by with 420W in Apevia QPACK, but just want to address these issues before I jump in and buy it.
I just don't want any trouble that I have had in the past with a PSU that took my hard drives and everything else with it when it went.
