I'm soon about to upgrade certain parts of my computer, CPU, Motherboard, Memory.. those parts are from 2009, and have served me well through countless hours of programming and gaming.

my PSU is from 2010.. its a Cooler Master Silent Pro M 1000W.. and as far as I remember it wasn't cheap.

I have a problem where I will once in a while lose connection to some of my drives, they will simply dissapear. I have another problem where sometimes my computer won't start my processor and drives. it will simply start the fans and nothing else.. if I wait 10-15 minutes and try again it works.

Now I have no idea if this is just my old 'now unsupported' motherboard thats causing problem.. if its the wires.. if its the 2009 Hard Drive.

Or its my PSU.. but the other things I'm gonna change anyway. What I want to know for sure, is if I need to change my PSU. Can I check somehow if it has any errors?.. any diagnostic tools or tests?

  • find a repair facility that has a PSU tester. It's a hardware device designed to test the unit under full load. You can also just try a replacement, it's not a high dollar item but don't buy the cheapest-- get a reliable middle line PSU from a well know manufacturer. – Tyson Jul 19 '14 at 12:33
  • You can use a software program like speedfan or one from the manufacturers website. If the voltage is more than 5% above or below the rated voltage your PSU has an issue. I would suspect the motherboard. – cybernard Jul 19 '14 at 15:49
