Hi All
My ATX power supply is dying.
Can someone tell me, if I buy another (300 w) off TradeMe will it just slot in with the mounting holes lined up - or are there different dimensions?
Thanks

It should be fine. I've yet to come across a PSU that doesn't line up properly. (Unless you're using one of those ultra-thin/HTPC type cabinets..)

Also, you need not get only the 300W ones- if you're getting a better deal for 350/400 etc go for it.

One thing to watch out for is to check if the PSU has SATA power connectors. Also see if you can get info on how many regular connectors are present (molex) so that you know it'll cover all your fans/components.

There are still plenty more things to watch out for while buying a PSU, like the rail ratings/load-handling factors, modularity, rounded (tubed) power cords and some other technical stuff but unless you're into overclocking or on a mission-critical production machine, don't worry about it.

Thanks for that reply. In the meantime I discovered that the PSU I needed to replace was an older type (6 years), with a 20 pin MOBO connection (which apparently they no longer make) so I bought a second-hand one which has slotted in nicely - and had all the right (and long enough) connections - including 2xSATA!
The real test will be when I start it up tomorrow morning in the cold - that when my old one was failing, needing to be coaxed into life by a hot blast from a hair-drier.
Thanks again.
