RE: Need Help to Build a 50W Load for PSU Load Test
Posted: September 10th, 2011, 7:49 amOld 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).
