Many people skimp on computer PSUs, forgetting its the heart of the system, till one fails catastrophically, and takes out their expensive CPU's, GPUs, SSDs and HDDs with it. I second the motion to just replace it, with a good quality PSU. It seems to me this is a matter of a component in my power supply on its way to total failure. If I can save myself the money of buying a new power supply off eBay that may or may not work properly by replacing simple components I would like to. The +5v has a good resistance on the motherboard itself. I have checked this resistance with my leads in both directions and tested the power supply when disconnected from the computer completely. My questions are: Should the resistance be that low?Īnd without a schematic is there any way to trace the +5v back without using my meter in continuity mode and trying to follow traces to get to the issue? The supply itself is a mess of silastic and very difficult to see on the top. The computer works but randomly restarts with no blue screen message. To the best of my knowledge the resistance shouldn't be that low.ĮGD IT EQUIPMENT DESCRIPTION YOU ARE BUYING A NEW x 1 HP 300w 24 Pin ATX Power Bestec ATX 0300 D 5 WC REV:B585008-001 EGD30 SHIPPING NO COLLECTIONSDELIVERED VIA.
