Before you pay for a new power supply you might just want to fix it if possible. Most of the time the capacitors go bad but are easy to replace.

For the ram I used the komputerbay on my 486 without any problems but other people have. Its a roll of the dice I guess. Expensive but haven't found anything cheaper.

Here is the memory that my EX490 has been running.

Looks to be still available:
