Could it be that it has a 20 pin power connector so it cannot be used on DDR2 or DDR3 systems which require a 24 pin power connector? I came across this in the amazon user reviews but that doesn't seem right.http://www.amazon.com/Antec-BP350-Basiq-Power-Supply/dp/B000H9J3ZC

I don't recall any problems with the pins when installing (I could have sworn it was 20+4) and don't have access to the machine right now to check it by eye.
After checking the specs with Antec and Intel, the Antec supports 20+4 which is what the Intel mobo requires.http://www.ehow.com/info_8125204_antec-bp350-specifications.htmlhttp://downloadmirror.intel.com/17250/eng/DG41RQ_ProductGuide01_English.pdf
Anything to this?
