PC Power Supply for DC Charger?

[Mad Armour]

Hi,

I'm thinking of getting the Great Planes ElectriFly Triton DC Comp Peak Charger but it's only accepts DC. Towers recommends a 12V power supply with a minimum 13A current delivery.

I'm thinking of using the CPU ATX power supply (12V at 12 - 18A, depending on models).

Will there be a problem? I've read about ppl using it but some mentioned about 'regulated' current modifications. Anyone has any experience in this?

My current batts are

1) AA NiMh 2100 x 8 for Tx
2) 5 cells NiMh 1100 Rx packs.
3) 6 cells NiMh 3300 sub C packs.
4) 6 cells NiCd 1700 sub C packs.
5) 12 V dry cell 7200 mAh
6) 1200 2s LiPos

Thanks for reading.

Cheers!

Hi

It should not have any problem so long as u use ATX power supply that has higher than your required ampere for +12V.

Remember that u need to short 2 wires to turn on an ATX power supply.

Thanks Super-Hornet but can you elaborate on the shorting or wires part? I'm not a technical person so I dun really understand.

Cheers!

Looks like useful infor here. I may need to do one also....but the current of 13A at 12V from the ATX, would that hurt the Hobbico Elite Accu-Cycle Charger which requires at least 2Amp.

Thank you.

It should not have any problem because the 13Amps is the max o/p for that ATX. Your charger willl tape approx 2 to 3Amps only.

Thanks for the link! I'll be getting my Triton soon, so hopefully can start to mod the ATX.

Sorry to hear about your recent accident. I hope you've made a quick and complete recovery.
