Hello guys,
I found an old ATX power supply which I would like to use as cheap power source of 5V and 12 V.
It has been working fine after I short green-black wires to start up it and plug 10 ohm/5W resistor as load to 5V/26A rail (red-black wires).
However after a minute this resistor became hot.
Without the resistor the power supply will not start.
I havent found a datasheet for this power supply.
Could you advise me a resonable resistor load and tell me how to estimate the value ?

Thank you.
