Need Help to Build a 50W Load for PSU Load Test

[shovenose]

Old CPU Heatsinks would be fine.

There is no 80%. It's simply Voltage x Amperage = Wattage

As shovenose said, old CPU heat sinks would be great.

You could also use PSU heat sinks, but don't attach more than 1 resistor per heat sink (and if possible, use 2 heat sinks, one on each side).

OK, thanks c_hegge .
