Modern-ish ones seem to run to about 12W for 7,200RPM, 20W for 15,000RPM. Quote: Running three IDE drives, the drives would power off and crash under disk load. One drive eventually died from the abuse. Running two IDE drives, I had occasional power cycling. I am now running one IDE drive and the system is stable. It sounds more like your power supply isn't really supplying 350W, or is failing and no longer supplying it, or isn't able to supply it on the right voltage rails. (That is, it's no use having a 350W PSU that can supply, say, 200W at 3.3V, plus 100W at 5V, plus 50W at 12V -- and that is how these things are measured -- if what your PC needs is 100W at 3.3V plus 100W at 12V.)
