Help with buying PSU.

Sir Lance15 · 07-08-2009, 02:06 PM

Hi I'm throwing out my older system and rebuilding a new one. I'm keeping the case, the old motherboard was a mATX and the one I'm going to buy is also an mATX (http://www.tigerdirect.com/applicati...4&sku=B69-2101). I know it will fit into my case, but my question is, what kind of power supply do I purchase? Do I purchase a mATX power supply or will a ATX power supply do? I don't seem to find much mATX power supply. And will a 450 watt power supply power up that board?

Thanks for your help.

P.S: BTW This is my first build

The biggest consideration will be the video card. Which one are you planning to install?

If your case is ATX/mAtx the you need a AtX PSU the mATX PSU is smaller in size to fit in slim cases.
