[SOLVED] dummy load on old computer power supply

[Vraj]

hello,

i have old psu, which has more apms on 5v rail.
i want to use it as 12v power source.
there is some ppl telling that dummy load is required for constant power supply.
all puts different values of dummy load.

i want to know how their value approaches.

thank you,
vraj

Hi,

Dummy load ... often call as "minimum load"
Depends on the type of power supply.
I can't think of another way as to look for the manufacturer's datasheet.
(Some supplies need a minimum load, some not)

In my experience you just need to take the green and black wires and tie them together, as they are the "On Switch" wires, and it should fire up just fine.
Yes, some switching power supplies do have a minimum load, but all the computer supplys I've checked just need to be switched on with the afore mentioned wires,
use them to connect to your on / off switch.
