I'm all over it. My current [NPI] 200W PC PS conversion is starting to sound a bit wheezy.


Thanks for the heads-up, good sir. I just ordered one. Now to dig up that box of sandbar resistors....

are these what are used to convert field chargers to ac power?

Yes your right here is a link on how to do it, Its not hard to do, I made one from a old comp power supply, Take care, Chellie

Ordered mine today. Thanks Chellie!!!

Just ordered one, my PC power supply just started acting up. Needed this.

A Little more info on converting a comp power supply and My Power supply conversion I cleaned up all those extra wires since that pic was taken

Thanks Chellie. I was worried. Didn't want to loose you in an electrical accident

My Family members would not mind, Then They can collect on my Life Insurance Policy LOL Take care, Chellie

I see an abundance of wires going into your plug-in box. That leads me to believe you parallel all 12v leads to feed the charger. I had thought any one lead for 12v +and- would do it but perhaps you only get the maximum watts out by paralleling all 12v leads???

Cute little light on top, looks really space age.

FWIW I only run one set of wires out of the PS and it powers my chargers fine. I have a Triton and 2 of these that I run all at the same time.

Hi av8djc yes I paralled the yellow wires and the black wires as per the instructions, to make sure i would get the full amps from the power supply, and i belive the green wire is the load wire going to the lic plate light, to make the power supply work, I power up 2 Astro 109 chargers and 1 electrifly charger all at the same time, works great for me, and it was FREE Take Care, Chellie

[CHELLIE]

Please Someone thank me its showing 666 on my thanks and i want to get passed that Take care, Chellie

[Rolling Thunder]

lol,oops chellie my bad.I always forget to do that

Hi RT I needed to get passed that terrible number Take care and have fun, Chellie

[Rolling Thunder]

I got my power supplier today.Now I just have to figure out how to hook it up-yikes

Anybody else got theirs & any pics of how they converted it

I was thinking cant I just use the alligator clips on my field charger & splice into the 12v DC line to power it.Along with a resistor

[dbcisco]

Should be here by Weds.
FedEx is taking longer to get it out of California than the post office can get parcels to me from China! Tracking info says it took three days to get from Anaheim to Bloomington, about 45 miles (45 min. drive). And then it sat at Bloomington from Fri. to Mon.

You need to have a multimeter so you can isolate all the voltage rails. Put the 10ohm/10W resistor on one of the 5V rails, and mount it flush against the side of the case so it will conduct as much heat out as possible.

Heck, here's the best HOWTO I've found on this so far.

You can eliminate the other rails he uses if you just want one or two 12V supplies. I will build in the 5V so I can power my servo tester or receivers.

so you have to use the wires inside the box.you cant just splice into the wires that are outside the box.and i do have a multimeter,thanks-RT

Here you go RT http://www.marcee.org/Articles/PCPowerSupply.htm

[Rolling Thunder]

well I plugged in my power unit today and nothing.No power.its a piece of junk.good luck with yours

[dbcisco]

A PC pwer supply will not turn on just by plugging it in. An on/off switch needs to be installed. Normally the power supply is "activated" when connected to the motherboard and not by itself. Pin #14 "green wire"

14 /PS_ON Green Power Supply On (active low). Short this pin to GND to switch power supply ON, disconnect from GND to switch OFF.

See this site for details: HERE

thanks I'll try it.it does have an on off power switch on the front

Hi RT you need a small load on the power supply before it will start to work, i used a LIC. Plate Light assy. and i did not need to use a resistor using that light, a 1157 or 1156 or 1155 Light bulb will work well.

http://www.marcee.org/Articles/PCPowerSupply.htm

[Next choose a location on the PS case to mount the automotive light socket. Mount the light and connect it to a "Common" wire and to a +5 volt (yes plus five volts) wire. You need a small "load" on the +5 volt side of the PS in order for it to put out it's maximum voltage on the +12 volt lines. Some folks use a 1 ohm 25 watt resistor. E-zone is full of opinions on this but I find a small load works fine. If you are not getting slightly over 12 volts of output on the "posts" you can add a second light by connecting it to a "common" and a +5 volt wire. ]

[Rolling Thunder]

it works!!
thanks dbcisco,I had the lightbulb hooked up the first time but there was nothing.Then when I shorted the green wire the light came on.Thanks all-RT
so I guess I have to leave the green wire shorted the whole time then
