I just got an RMA’d P5P800 and I bought a new power supply, an antec 400w smartpower 2. I’ve hooked the hole thing up but when it boots it shuts off after a few seconds. I watched the interior lights on the mobo and the LED stays lite the hole time and doesn’t flicker. Any ideas? Tomorrow morning I’m going to install my old PSU and try that.
P5P800
Intel 3.0GHZ HT
1GB corsair
eVGA 6800
Many many HDD’s (tried with only 2 and still did same)
1.2 TB HDD Space on 6 drives. All detected fine by Promise ATA controller add-on card before power-down.
After reading other posts with this situation I decided that tomorrow I will try to hook it up on my countertop and see what results I get.
Here is more of the story:
I just got the MoBO back after RMA’ing for a AGP that slot that killed 2 cards that when in it. I just the the EVGA card today new. The asus rep who was not very knowledgable only say that some MM transistor had been replaced. I have to really assume this PSU is good, but I will try with older PSU known to work fine. Chip was fine when I took it out of the Mobo before. Mobo was working fine with PCI video card before I sent it back.
Could the fact that I didn’t redo the thermal compound between the CPU and heatsink cause this quick shutoff? I’m just trying to think of all possibilities. Could it be a faulty ground in my case, and if so, what is the best way to remedy that? Is that the fault of a screw into the case ect? I didn’t have this problem before I sent it in.
Well I changed the IDE cable and got all the HDD’s properly detected, and the mobo detected the ram fine and the proc fine. The video seems to be fine as well. Am I left with it being a problem with the mobo or the psu?
PLEASE HELP!
