Hi there, just a quick question are all the power supplies the same size dimension wise?

[Carbon]

Depends. If the computer is a Dell or other prebuilt, it may have a custom kind. Usually these are found in slimline cases or such.

A vast majority use the ATX spec, though, which means they'll all fit.

Like Carbon said, some prebuilt machines have different sized power supplies. Also there are larger retail ATX power supplies, however these tend to be the PSU's that provide 1KW+

Completely wrong advice

Original poster is from the US (see flag), so Maplin UK wont help him .... also that is not a PSU for a PC.

Also post is 4 months old !!

Please only give advice if you know what you are talking about !

It's being dealt with.

It all depends on the computer;s company so, you have to contact to the vendor because computer expert can check with different power supply.
