LOL, I was just going to make a post about converting this very power supply. There is another seller I got one from that sells them for $16.95 shipped via fedex 3 day. Cant beat that with a stick. http://www.ebay.com/itm/HSTNS-PA01-H...E:L:OU:US:3160

The power cord needed is C19, they can be bought on amazon, cost me more than the power supply did but still Im far under the cost of a 60 amp power supply. http://www.amazon.com/dp/B0012EK2RE/...0_M3T1_SC_dp_1

I bought the Hitech X2 400W, basically the same charger you have.

I will give you this warning though. When the small high rpm fans in this puppy lite off it sounds like a 747 on the approach! There are ways to work around that though and to modify the output volatge up to 13.1V. Takes a little soldering skill and a few resistors.

I went pretty elaborate on mine placing switches in the rear with varied ohmic values for variable speed on the fans and installed bi metal switches for an over ride. If it starts getting too hot the fans kick to high speed no matter the switch position.

I mounted a biding post through the rear of the supply as well.

There is a pretty darn good read and lessons to be learned in modding this and a few other PSU's

A total of about $50 (cord being the most of it) invested and a little of my time was a lot cheaper than the $200 a commerically made RC specific power supplies that are large enough for the load. Whats even worse is some of the sites selling these chargers dont sell power supplies capable of handling the current. I ran the charger full tilt charging 2 packs at 20 amps each and didnt come close to putting a full load on this power supply, had the fans on medium. The resistor network I put in feeds the fans 5v, 8v or all 12V if the thermal switch kicks in. Normal balance charging at 5-10 amps the slowest fan speed is sufficent and sounds like the average ATX power supply, fairly quiet, quite simply once the fans on the charger spin up you cant hear the power supply fans on low at all and can tell there are more fans running on medium speed but the dB level isnt much higher.


I agree about the Max amp power supplies. I saw it and about puked when it was so obvious that its two server power supplies with a wrap around them, very cheesy looking and at a premium price!
