I seem to be having a strange issue with my PSU that I use for my computer.
Long story short, I built my own computer about 1-2 months ago, and was having no trouble with it for about the first month.
About that point in time, my computer suddenly just stopped turning on. I tried a different PSU cable and suprisingly it worked for about another fortnight, where it happened again. Swap it out, works fine.

My PSU is a Thermaltake 500W W0410 and I bought all of my parts brand new. I tried connecting my "faulty" cable straight into the powerpoint/wall socket instead of a powerboard, but the same issue persists. Could this possibly be a computer issue? PSU issue? If more specs are required, I'm happy to provide them.

What could possibly be causing this "faultiness" in the cables? I'm swapping the new ones out for the old ones that were previously "broken" yet they work fine.

  • @Ramhound :O Well then, I guess for my whole life I've been using Australian slang. What I mean is, a "wall socket".

Well, after all this time, it turns out I solved the issue.
Whatever the issue was, the PSU was not the fault.

To begin, the cable changes were strange, and my PSU almost had some sort of ghostly "memory", where it wouldn't let the computer turn on if I swapped between two cords. I had to use three or more, in a set order. If I went back and forth in the ordering of my cable swaps, it wouldn't work.

Then it stopped working completely, so I opened it up and looked online.
Turns out the only issue was that I had to replace the tiny button battery in the motherboard, as the shop I bought it off obviously had it sitting there long enough to kill the thing.

The power cable issues must have just been zapping the battery giving it a tiny bit of life. As to why I needed specific ordering, maybe the house is haunted. :/

Problem solved.
