Use PC PSU for car radio
Humbug - 21/1/11 at 08:35 AM

As above - is it possible? I have got 3 PSUs of various types and an old car CD/radio taking up space. I thought I might be able to rig them up in the garage for some music while I work, but the PSUs have tons of different wires coming out of them.

So, has anyone done it? If os, how, and how easy was it? If it's not fairly easy then I won't bother as I have an old hifi as well... just thought this would be a bit neater.

Cheers

Simon

Yes it will work, but they are quite big, with a mass of excess wires. in my garage im running a car radio off a small 12v transformer. It was off an old NAS box i think, as a lot of IT equipment seems to be 12v. Much smaller, and safer to use

yes it will work but make sure it has enough watts to power the head unit or when the volume is high it will just turn off and potentially kill the psu.

:O)

there is also the possibility of hash,.... no not that kind. Electrical noise from the power supply that would be on the DC lines of the radio. This might make the audio poor.


A better PSU will give better results, but IMHO a free junked mains radio might be better,....

should work. old car head units arent powerful. i used an old 600 watt psu to power my 300watt car amp and sub indoors....the psu broke . you'll need to trick the psu into thinking there is a motherboard there telling it to turn on. i can't remember how that works right now, but there are plenty of illustrative tutorials on the internet

Ive tried all sorts over the years, and IMO the only thing that has ever worked properly, is my new battery powered DAB radio that i got for christmas.

The cobbled together radio setups are always hard work unless you run a proper aerial to the roof. They also become very untidy and a potential fire hazard after the dust settles on them and into the vents of the PSU. Lets face it, the safer we can make our garages, the better really.

OK, thanks chaps. it sounds like a lot of hassle for not much reward.
