I don't know how you measured the load, but it is important to measure very short power surges. In particular, I'm suspicious of that load during raid1 resync. Could your technique catch a 10 msec spike etc?
Even the cheapest of the cheap powersupplies can handle spikes of the duration you mention. In fact these are designed to supply of capacity tp park heads on disk drives in the event of a total power failure, and this extra capacity is available to handle spikes. The power supply the OP mentioned was adequate for everything mentioned, and the only scenario that might draw more would be burning a DVD while doing all those other tasks at the same time as stressing the GPU. The fact that the OP's problem persists suggests that the power supply was not an issue. I've often uses a stip chart recorder for measuring total power consumption and power monitoring of problem computers. I've never seen a machine draw anywhere NEAR what the psu was rated. Doubling the capacity does not necessarily by better protection as the machine may be drawing power in the crappy portion of the PSU's output. You can see this if you look at a detailed output characteristics chart for the PSU. (something you have to dig for, as its not always published). I would suggest the OP put on a UPS capable of running the machine for 10 minutes at least. Also, be careful about running the Voltcraft device when plugged into a UPS. Lots of these cheap units are not designed to handle the near square wave produced by the typical UPS. I'd also start digitally measuring temperature of surface mounted components on the mobo. (Digitally as with a finger). The fact that a fan helps but a PSU does not suggests something is poorly heat sinked. -- ----------JSA--------- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
