In order to try and solve a problem on a family members PC, I've come to the conclusion that I should try to replace the power supply. The problem that I'm trying to resolve is quite odd, but I'll deliberately avoid complicating the thread with those details at least for now.
The problem I've encountered is that the replacement PSU that I bought is too physically big for the case, and I'm not sure what type of PSU I should be ordering instead. I didn't think for a minute what was installed was non-standard so consequently I didn't think twice when buying a replacement, which I've since returned.
So the part that I've swapped out is a Q-TEC ADT-300. On speaking to the guy in the local shop he suggested that a replacement would be expensive and that I'd be better off buying a new case to go with the power supply that I'd previously bought, but this seems a bit much for something that I'm not even 100% sure is the root cause of the problem. If I'm honest, he wasn't able to tell me the model type of PSU I currently had and suggested it was a unique type of mass manufacturers unit, which I very much doubt.
What now seems most likely to me is that this is a micro-ATX power supply but with this or any other identifier being absent from the original Q-tec model (at least as far as I can ascertain), I'm not certain. Here's a picture of the old PSU in case that gives anything away.
I suppose the short question is, what type of PSU should I be buying to replace this one.
