Load on PSU Maybe too Little ?
Posted: Wed Oct 19, 2011 2:38 pm
I have been using the Intel D510MO motherboard partnered with the Winmate DD-24AX PSU in a home brew case for about 6 months now. I have fitted a fan to the case so it runs cool. I run Win XP as a Skype server 24/7.
My problem is that this system blue-screens (F4 usually & 7A once) at intervals that can vary between 3 days and 20 days. The average runtime between failures is probably around 7 to 10 days. The failure always occurs when idling. I have run a Prime 95 test for 36 hours without encountering error. I have introduced a UPS to try to eliminate potential mains influences.
My diagnostics is beginning to think that maybe the fact that power supply is very lightly loaded is a factor. The Nominal power output of the Winmate PSU is 130 watts whereas the overall load of the system is about 25 watts while idling. Has anyone encountered a similar failure rate in a setup such as mine?
I am considering placing an additional (dummy) load on the 12 volt rail to test my hypothesis. If the system runs for say 30 days without failure under this heavier load, then I might be on the right track. Unfortunately it is a long time frame that I am caught up in.
Any suggestions would be most welcome.
