Hi

Amazing that a system which idles at 50 watts and always uses less than 100 watts can't start up with a 355 watt power supply. Apparently SATA drives hit the 12 volt rail harder than IDE drives used to.
Really? How? Why? I seem to remember reading that my Western Digital 500GB 7200rpm SATA drives use 6W each. And this AFAIK was from the datasheet/specs from WDC.
Correction. 9.5W
Mode 12 V 5 V Power Read/Write 450 mA 800 mA 9.5 W
Is 6W really that much of a difference to cause this problem?
Surely it's probably due to a rubbish unbranded PSU with badly rated/cheap components? What make is it?
I seem to remember reading/being told (before I bought my PSU) that the generic PSUs one gets free with cases usually are quite rubbish, not stable and generally can't provide enough current on the power rails. Perhaps this is the problem?
