Whats a good 12v power supply to buy to bench test car audio?

As small as you can find, the HC600 mentioned above will be just fine.

Hey guys, I know this is a bit old. But I thought this might benefit some of you greatly ... this is my set up right now( yea, it's messy, but it's a work in progress right now)... it's running at 12.8vdc @ 240 amps. We have figured out a solution to get it up to 15vdc, just don't have pics of it yet. And it won't set you back that much...(for what it is)...I will have it all tidy and neat in it's own case and all the details worked out in the next month or less. And this will only set you back about $200-250 TOPS .... Not alot for 240 amps of power ....and adjustable voltage 11.9 - 15vdc

And you can parallel two of these for right at 500amps of test bench power ....

I can post up all the details so you can make one yourself if there is any interest ....

I am NOT trying to sell these. Just want to make sure that is clear .....

Just trying to help out other audio heads like myself with a fairly cheap solution to this issue, that you can put together yourself.

I'm interested in more details. My hobby is to run car audio amps from the 90's in my home. I currently use pc power supplies and have had great success with them especially after replacing the fans with noctua. the limitation is that I can't really run anything more than 1000 watts due to limitations of commercial pc power supplies. If I ever wanted to run one of these newer amps with thousands of watts, I can't do it.

I hear the Jaws music playing as Popwar comes to downvote.

This is the brand i have. They have various size options. I have owned mine since 2013. I don't use it very often, but it has always worked when i ask it to.

Those don't look to bad
You can run them parallel to up the amperage
$110 for 50 amps is a good price

I ripped the power supply out of an old tower computer to test 12 volt stuff, but it’s strongest lead is only 12 volts with 2.5 amps, so it’s good for maybe 100 watts. I use a little pioneer head unit and an old jbl crown amplifier, but it is literally just for testing. Try to run anything over 100 watts and it protects and shuts down immediately. It was free though.
