Power supply?

Hi How can I build a 45 amp power supply to power a linear amp out of computer power supplys

It's difficult to modify an existing supply to supply different voltages and currents. In many cases impossible.

First find out what you need, volts and amps. Is it really 45 amps? At what voltage? Then look at what the computer supply puts out. Probably 5 volts at 10 amps or so. Are they the same or close?

The existing current can be higher, and if the voltage is too high, you may be able to reduce it with an added regulator.

If not, you need to buy/build a new supply.
