Default Fun load tester

Got this fun load tester, but it gets hot quite quickly so can't be used for extended burn-in after a repair

Could probably be useful (with a suitable adapter) along with those horrid "power supply testers" to maybe get slightly more accurate results.

Put a fan over those resistors for longer testing.

There are pads for measuring the voltage with a meter.

That works, but I'd still not risk leaving it overnight unattended.


Such a disappointment; the unit should consume about 28W

5 Ohm on the 5 V standby line,
24 Ohm on each 12 V line,
3.3 Ohm on the 5 V line and
3.3 Ohm on the 3.3 V line

I measured 48W into a power supply with a Kill-A-Watt unit; that puts the power supply efficiency at around 60% (at about 10% load)
