Psu broken or not enough power? Tags: Homebuilt Systems Last response: October 15, 2011 12:20 PM in Systems Share kieros October 13, 2011 9:37:21 PM Hello. I recently bought Silverstone nightjar 400w passive psu. I have problems running system stable with it. Pc just randomly shuts down and fails to power up again. Computer shuts down randomly, from 2 minutes to 30 minutes. It's not about cooling, I've tried open case + fan attached to PSU, same result, random shutting down. I'm unsure, if the PSU is not powerful enough for my system, or is it simply broken. System specs; Q8200 core2quad, (TDM 95w) Nvidia G210 (appr.30w) 2 sticks of DDR2 ram 3 7200rpm sata drives 3 usb devices taking power from usb-port 1 soundcard + addon card for it. keyboard+mouse System runs fine with 600w PSU and has run with 500w PSU, so the motherboard works fine. Any suggestions, please?

Yeah, that what I do, use different PSU. Please, what do you think about the wattage ? Is the PSU insufficient ? The Silverstone gives 324w on 12v rail. I ask this because I don't know if I should send the PSU for repair.

I think it could be sent to repair, but, do a noiseless psu required? if not, could u upgrade it to a powerful psu with fan? vitornob October 14, 2011 12:56:59 PM Ur PSU review: http://www.hardwaresecrets.com/article/SilverStone-Nigh... by this test the PSU should be working nicely with ur system kieros October 15, 2011 12:20:32 PM vitornob said:Ur PSU review: http://www.hardwaresecrets.com/article/SilverStone-Nigh... by this test the PSU should be working nicely with ur system Yeah, that's what I calculated too, it should work nicely. I'll send the PSU to repair. I'll be using the computer in small room, which I use for audio recording, so silence is needed. The current psu does well though, but it's just that I know that there is silent psu... Can't find your answer ? Ask !
