about to wire up 4 480w computer power supplies together.

[skylineTT 10+ year member]

in order to keep it at around 12v and add all of the wattages together, should i wire them in series or parallel, meaning all of the yellows and blacks together or the yellows from one to the blacks of another until i have one yellow and one black left. thanks

Buy a real bench power supply //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

I GOT PLENTY FOR SALE

WAS JUST ABOUT TO MAKE THE THREAD LOL

LMK I HAVE MORE PICS AND DIFF UNITS I RUN THE ENTIRE BOARD @ SHOP OF JUST 1 60 AMP LIKE THIS ONE

yes and my psu's are ideal for that and bench testing demo inside w/o engine runnung etc...

if you series it will ad voltage, parallel will add amperage/wattage, i dont know if its safe to do with power supplies though, i know with batteries its fine

So this is supposed to be a website where people help each other, and you post a bullshit reply like that? //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

Yeah, doing things the right way is really ****ed up, I know.

Well, real power supplies intended for shop use are basically computer power supplies anyway, besides he asked specifically about wiring them in series or parallel, you could have atleast told him they needed to be wired in parallel to retain 12v instead of jumping to 48.

Make sure someone is recording before you do. I hate letting any epic moments get away. I have a feeling this could be one of those moments:fyi:

If he was running a 5A load, I'd tend to agree. But even 60-70 continuous amps is a lot of current for a good quality linear 12V supply, without mentioning switched-mode supplies.

Bottom line is, I'm not going to recommend a halfassed way of doing things.

i'm no electrician but how would 2 independent PSUs physically be wired together via the same wire(s)?

That's 2 separate regulators trying to control the same 12v run... That sounds safe.....

I could understand getting a SINGLE RAIL PSU and wiring all of it's 12v wires together BUT.... PSUs do not offer 12v grounds capable of grounding the 12v power they output...

Ah HAh! didnt think about that did ya?

Try buying an 80A single rail PSU for $180 and try grounding up to 80A worth through the 12v ground wires... fire will occur unless psu goes up in smoke first.
