MSI X58 Platinum will not post - yellow LED near JUSB1/JUSB2

[wgoulet]

Hi all,

I suspect I have a faulty motherboard but I wanted to get ideas before trying to return it.

I have a MSI X58 Platinum motherboard with an Intel I7 920 CPU. I am currently testing the board out of the case and have 1 stick of Corsair DDR3 2 Gb 1600 Mhz RAM, a Nvidea GeForce 9500 GT video card, and a 680 watt power supply connected. When I power on the motherboard, I see 2 LEDs light up, a blue one near the memory bank (which indicates memory is installed correctly according the manual) and a small yellow LED located about 1cm from JUSB1/JUSB2 connectors on the motherboard. The CPU fan and video card fan spin for maybe 1 second, then immediately shut off. The LEDs however stay lit until I physically power off the power supply.

I originally suspected a short of some kind which is why I repeated my test out of the case, but I'm getting the same results.

Any suggestions? Otherwise, I'll take a shot at returning it to Microcenter.

Thanks for any help!
Walter

Do you have another power supply to test out?

Actually I do; I'll give it a shot. It's only a 450 w PSU, but that should be enough to at least try to see if I can POST. Will report back shortly.

Yes, it should be enough with the system in barebone conditions.

Sure enough; the board POSTed with my 450 w PSU. This is a brand new BFG LS power supply, ATX12V 2.2 at 680 W so I figured that PSU would be perfectly compatible. I suppose it's possible that the PSU is bad. In any case, it's a lot easier to deal with returning a PSU as opposed to a motherboard.

I don't think I would have ever considered the PSU in this case; I guess I have another step to add to my standard troubleshooting.

Thanks for the help.

No worries.

I hope your next PSU will run without issues .
