Testing loop with 12V car battery

post #1 of 14
Thread Starter 
I want to test my new loop for leaks . Can I run it off a 12V car battery or will that mess up the pump?

It should be able to run of a car battery but why not just jump start your PSU ?

Pull all cables out your motherboard and gpu's and just have the PSU hooked up to the fans and pump. then just jump start it to make the pump run.

I want to play Battlefield while I let it run , thats why I don't want to do the paperclip trick. I want to let it run in the garage over night. I am just worried about the amps in a car battery. I guess the pump will only draw what it needs.

I use one of these Phobya PSUs to fill and leak test my loop. 90W is enough for a couple of pumps and a few fans.

Yes you can - 12V is 12V.

Actually you will probably find a cars battery voltage to be a little higher when fully charged - around 12.6V ish - Can your pump be overvolted ?

Assuming a 'standard' car battery of 60 Ampere/hours , A D5 maxed draws about 2 Amps, so would run for 30ish hours - Should be long enough for your test.

A small note of caution - Directly connecting to a battery will not give you any short protection - If any wires get crossed or touched expect a big bright flash and lots of heat very, very quickly.....

Hope that helps

Yes it helps thanks. It is actually a deep cycle battery from the Landy that is not fully charged . Will test voltage before I connect.

Won't the amperage of a car battery fry the pump?
