Performa 450 dead

[toples50]

I have a Performa 450 but seems completely dead.I have added a working battery but nothing.Does not start up or any sound from power supply...

what can I do?

Probably a bad PSU (pretty common) you can have a look at outputs with a multimeter.

Capacitors should be replaced as a matter of fact on both the PSU and Logic Board.

Switch on the PSU and test for power on the power plug - I bet you money the PSU is dead/needs recap.

Cheers

Its the power supply we had a power macintosh in 2010 that we had to throw out cuz the power supply was dead. Needs recapping
