The DPS600 is very popular, and there is plenty of info on conversion.

It is rated at 500 Watts which will manage a bit under 30 Amps when charging a 4S.

I have been looking at the DPS 1200FB but here in Germany the cheapest I have found is for 70 euros. Are there others that are recommended?

power up HP ML530 570 POWER SUPPLY

Grounding the short pin and the pwr on pins gets the fan roaring like a 747! It also produces blade voltages as follows:-

Blade 1 - chassis gnd
Blade 2 - +3.7V (3.3V)
Blade 3 - +12.82 (12V)
Blades 4,5,6 - gnd
Blade 7,8 - +5.48V (5V)

I still have two concerns. According to a sticker on a supply on a web site (it is not on mine) the Status LED is supposed to be steady green if all is well. Mine is not lit. There is only a green AC pwr LED.

Considering that there is only one blade for 12V, I wonder about its current capacity. There is nothing on the PSU to show what the current capability is and I couldn't find anything by googling. It is a 750W supply so it has to be capable of a lot of current from somewhere!

Anyway, some progress has been made. Next step is to test it with a load. I will report back.
With this pin connection the PSU works very well.... thank you

Actually, I was a bit cryptic there. The PS rating is higher but the effective charger output is 500Watts.

The DPS600 does 47Amps at 12.15V. That's just over 570 Watts. However charger efficiency of say 90% pulls that down to about 500 watts output from the charger.
