Is it safe????

Hi all,
Please can somebody tell me if its safe to use a PC PSU to pernamently run a car sub amp,whilst I wait for funds to buy a indoors amp?
I did search but want to make sure its safe to do so.
Thankyou

As long as you don't pull more than its rated current, it should be fine.

It works very well I will tell you. I have a 400 Watt Kicker amp for 2 10" Kicker Comp subs under my computer desk. It kicks good. A modern power supply will probably keep up excellently.

I can't wait until they decomision the pulverizer controllers at work. The circuitry runs off of two big 12 V 40 A power supplies.

Load either the 5V or 3.3V line so you are pulling maybe 100mA or so on it (a resistor with a small heatsink) and you should be fine. You may find that your 12V output is a bit lower than expected without the load on the 5V (or 3.3V) line.

Don't worry too much about pulling too much current- the PC power supply *should* shut down its output if it finds a fault, i.e. too much current draw). Power-cycling it should bring it back on.

Cheers
