Powering a 12V Charger via Computer PSU???

Hi Guys,

First, I'd like to say this is a great forum!!

Im just about to get into RC's, and I am wondering if this is possible?

Someone suggested to me that I should be able to power a 12V Charger using the Power Supply Unit from a Computer.

Would anyone here be able to shed some light on this matter??
Is it possible, and if it is, does anyone have any links/URL's that show the process.


Thanks in advance




Coney

all you need to do is use a 10W 30ohms resistor to short the 5V wires with ground (all the 5V with same number of ground), joint all the 12V+ wires and ground wires as the power output you connect your charger to, then short the power on wire with a ground if you are using ATX power supply

i have done a couple of those but i found that their output voltage is a tad low (11.8x volt) and considering buying a decent 13 - 15volt unit

hope this help

the link is the full monty if u want to do a conversion.
what i(lazy bum) do is just load the 5V output with 10 Ohms 20-50W resistance BEFORE i plug in the charger.
yes,as mentioned mine is also a tad low on voltage,and charging transmitter packs are problematic.

I did it this way, and it've worked well for a year by now.

I've found that running a fan off of the 5v side will bring the voltage up a bit. Bonus with the fan is you get to cool your batteries too.

Hi sands,

Is that with an ATX or an AT PSU?

Here is the PSU I want to use:

APEVIA See-Through ATX-AS500W-BK 500W ATX12V Power Supply

This is the Charger I am going to be getting soon:

Venom Medion Dual 10 Amp LiPO Battery Charger with Audio Speakers

I am wondering if someone has a parts list that I need to do this conversion?

If so please pm me.

do you already own this power supply and did you have to bump so many threads?
