jthor1 Posted January 22, 2007 Share Posted January 22, 2007 Specs, ASUS M2N-SLI Deluxe, AMD 5200+ (89w), Corsair XMS 240 DDR2, 2x1GB. Corsair HX620 PSU. WD raptor 150GB HD. evga 7950 GT KO Video card and two optical (DVD) drives. I put this system together, installed windows, ran Prime95 and Sandra software for over 20 hours burn-in. No problems or errors. I shut the machine off, pack it up deliver it to the customer, nothing. When I flipped the toggle switch on the power supply all of the fans (PSU, case fans and video card fan) spin for 3 seconds and then shut off to never come back on once the power switch on the case is pressed. I thought it was a bad PSU. I replaced it with a known good supply from my computer, Enermax 535W. Same thing. I reset the CMOS, same results. I reassembled the motherboard outside of the case with the video card, cpu and ram. Same results. I have tried without the video card and RAM installed, same results. I RMA'd the motherboard and CPU since I didn't know which was bad and I can put the PSU in another machine and it boots it up. I noticed the whole time the Standby light on the motherboard was on. I received the new MB and CPU, after reinstalling the new Motherboard and CPU I proceeded to do the burn-in process again. One and a half days later I pack up the system and deliver it to the customer, all is well. Two days later he calls me and says it is doing the same thing. I am now suspecting the PSU and suggesting that the customer RMA the PSU, CPU and motherboard. I have read that ASUS recommends 600W PSU for a "full configuration." What are they considering a full configuration? Two video cards or just a "complete computer system?" That seems awfully high. I am asking; I am way off base on diagnosis or has the PSU has just wiped out two motherboards now? Remember, I am not even pressing the power button on the case, this is just flipping the power switch on the PSU to "on." Jeff Link to comment Share on other sites More sharing options...
