Can a Computer Power Supply Used as Car Battery Charger

[erick_214]

Hi guys,

May nakapag-try na ba sa inyo na gamitin yung computer power supply na pang-charge ng car baatery?

Paano ba gawin ito?

TIA

no it will not work because the minimum voltage needed to charge a lead-acid battery is 13.2 volts and the computer power supply puts out only 12 volts.

For what purpose?

Trickle charging?

Naka gawa na ako nyan, and I'm using it sa bahay.

DIY lang, zero to minimal cost!

Hi Sir,

Thanks for your reply. Hindi lang sana pang trickle, kung baga pang-charge na rin kung sakaling ma-drain. At balak ko rin sana gamitin habang nagpapatugtog ako ng sounds gamit yung set-up ng kotse.

So posible ba?

Tsaka kung sakaling gagawa ako sa house ng sub woofer at may 1000watts apms ako paired with a 15" 2000w na sub eh pwede pa kaya yung power supply ng PC..?

TIA

mababa ata amperahe ng power supply di kakayanin load.

Not all power supplies are created equal. If you go with an established brand of power supply (Corsair, Antec, FSP, Thermaltake, etc) and shop wattage ratings accordingly, you can see stuff with as much as 60A on one output rail. Quality power supply units can be pricey though.

If you plan on using a PC power supply unit as a charger, you'll need to read the labels to make sure you get the wattage or amperage you need. Otherwise I think it should be feasible.

if you can manage to up the output voltage to at least 13.2 volts, then you can use it to charge your battery.. a little longer time (o sige, a lot longer time) than what the usual car battery chargers need, but it'll do the job.

Ah, ok so basta't ma-modify yung PSU to have an output of 13.2V+ would be good. Tingin ko naman ay magagawan ng paraan ito.

What about using the PSU as the power source of my ampli? Kakayanin kaya? Napansin ko kasi maninipis yung wires ng PSU kumpara sa wire na ginagamit papuntang battery ng car eh. Ano sa tingin nyo guys?
