PSU not for the Carputer

**84RegalRider** · 07-21-2005, 12:57 PM

Hey i was wondering if anyone could be point me in the direction of how can i hook up a psu so that i can use the 12v/5v rails without it running a computer as well. I know switching power supplys have to be used under load, but does that mean i just need "something" hooked up or do i need to like add a resistor or 2 to a few wires???

Thanks

Connect green to black on the ATX connector (use a paperclip).
And put a couple fans on a power lead.

Should start right up for you!

Thanks, but with the green and black, just for a moment or is that always connected and then take it off to turn it off?

thanks

Alot of regulators are switching regulators and need some sort of load.Sometimes the fan acts as a load. I always put a 10ohm, 10 watt resistor on the 5v line, and put it on a heatsink with some thermal compound.
