Hey.

I bought a picoPSU-160xt for my new rig, and it can not seem to boot the PC. I've booted to BIOS with another PSU (RM750) for testing purposes.

The pico is being powered by a 19V 6.3A charger, which should be sufficient in my eyes. Nothing seems to happen when booting. The motherboard does seem to get power as the LED can be turned on, aswell as keyboard LEDs light up when it receives power. Any ideas?

The unit has been tested thoroughly with a voltmeter, and stays at 19V when trying to boot, if that has any significance.
 
Also, have a look at the table here:

Volts (V) Max Load (A) Peak Load (A) Regulation %
5V 8A* 10A +/- 1.5%
5VSB 1.5A 2A +/- 1.5%
3.3V 8A* 10A +/- 1.5%
-12V 0.05A 0.1A +/- 5%
12V 8A 15A Switched input
(sorry - formatting got a bit messed up)

Are any of your components drawing more than this on their respective rails?

I am not sure how the paperclip test will work on a fanless PSU?. Either way, the power button and LED both pulled 5V, There were 12V in some of the 24 pin and the CPU 4-pin was completely dead.

An Athlon-5350, and yes, I think you are right about that. Thanks. I will see if I can find a 12V power supply.
