I know its been done so many times before, what i plan on doing is using an atx power supply to drive a 200 watt linear RF amplifier, the supply is 370 watts total output.
Ive modded these supplys before, but not with a load as large as 200 watts, i plan the usual approach, a power resistor to the 5+ volt rail, normally 10 watts 10 ohms does the trick, on a couple of supplys ive had to go to 5 ohms at 10 watts, to get + 12 volts output.
Can or has any one else loaded an atx power supply this heavy, i must state the power consumption will be on about a 50% duty cycle.
Any ideas as to thoughts appreciated.
