Hi
After a minor bang my HP Z200 workstation stays dead. Investigating the PSU, a DPS-320KB-1 A, shows a blasted resistor (R901) near a powerswitch IC (TNY279PN). I cut out what was left of the resistor to be able to read it but I'am not 100% sure reading the first color code. It looks like braun. So its probably a 1 Ohm with 5% tolerance. But how many Watt could it be. It looks like a safety resistor. I cannot find any scheme of this PSU. On Youtube is only one repair video without comment in which they change the power-IC. Any suggestions to make this PSU a life again? Could it be only the IC with resistor R901 or is it mostly more severe. And which wattage should I use for this resistor.
ps: switching to a another standard ATX PSU is not possible because its custom built for HP with different pin layout. So Nice HP :-\
Hope to hear from you guys!
