Dell DPS-670 power supply

This is adapter for standalone server power supply Dell DPS-670. This one need some cooling so I added 80mm fan that is connected to 12V output. To make it running you need to short pin 4 and 23 to the ground (pins 9-12).
Pins go like this:
1 5 9 13 17 21
2 6 10 14 18 22
3 7 11 15 19 23
4 8 12 16 20 24

Copper blades next to the pins (1-3) are GND and 4-6 are 12V.

Works great for my RC charger :)
