Intel DG41RQ Mobo & Antec BP350 PSU Compatibility?

Last response: in Motherboards

A tech told me that I blew the mobo by installing the wrong PSU. Is this true? Is the Antec BP350 PSU the wrong PSU for an Intel DG41RQ Mobo?

Problem: No display. No beep on boot. (With or without external speakers connected.) Mobo green lights, case and cpu fans spin. PSU connections look ok

Removed RAM - no beeps (should be 3)
Tried booting with either stick – no beeps

Removed CMOS Battery for >1min and replaced. No effect

Might be BIOS issue?
-Full CMOS Clearance (out for >1hr) then BIOS recovery?
Possible bad mobo, CPU or memory? (likely)
Mobo shorting on case? (doubtful)
Meter test PSU? (PSU should be fine for requirements of PC)

A bad PSU can damage a motherboard but the Antec BP 350 meets the required ATX std for that motherboard.
No beeps (with case speaker installed) points to bad board.

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. see 1st review

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.

Anything to this?

Looking at the 20pin and the 20+4 pin connectors many boards run on the 20pin even if they have 24 pin connector regardless, just as long as the 20 pin is inserted correctly..
