Yup, once I get some plugs (...which I still haven't gotten around to ordering...), I'll be adding a ground post or two, a 3.3V post, a 5V post, a 12V post, and an adjustable 0-12V post, hopefully with a readout...I'm still looking into that.

Re: Adjustable bench power supply from computer PSU
Thread revival! Mwahahahaha! It lives!!!!
So I never did end up putting plugs on this one, but I made another one.
This one is a little different..
First off, I'm not starting with a random garbage PSU...I need to actually have dependable, high-current supply from this one, so I'm starting with this:
PC Power & Cooling Silencer 500W.
Well, that's what it was like a couple years ago. Then it got cables cropped for MightyMite...which apparently I don't have any pictures of...
And here it is now!
Like I said, this one needs to be able to supply high current levels, so the plugs are fed with four wires instead of one.

Re: Adjustable bench power supply from computer PSU
I have that same PSU running my desktop, and it's great. 35 amps on the 12 volt rail is excellent for a 500 watt PSU.
Re: Adjustable bench power supply from computer PSU
Heheh, yup. That's why it was sacrificed.Well, that and the fact that the way I had modified the cables made it useless in most computer cases... That 35A rail will serve it very nicely in its new life as a battery charger PSU.

Re: Adjustable bench power supply from computer PSU
Let's see if we can start a car with that...
lol
Re: Adjustable bench power supply from computer PSU
I'm guessing probably not...though maybe if it were a small, low compression, engine. My car battery charger has a 'jump-start' setting that puts out 75A.

Re: Adjustable bench power supply from computer PSU
You've inspired me to do this with a spare PC Power and Cooling Silencer 470 I have. I'm going to try to follow this guide, for more voltage options.

Re: Adjustable bench power supply from computer PSU
that's not a bad guide tech - I referenced that a few times when building Power House
Arctic Cat * Maximum Security * Cribbage Board * Rockin Case * Armor Redux
Tempest SXR * Power House * Red Comet * ICHIWZ * Acrylic Headphone Hook

Re: Adjustable bench power supply from computer PSU
Cool. Just keep in mind that the current limits on the - rails are different than the current limits on the + rails. Also, YMMV, but that guide only says to put a load resistor on the 5V rail and I found that I needed one on the 3.3V rail as well.

Re: Adjustable bench power supply from computer PSU
Very nice and useful project, thanks for all the hard work. I will build a bench PS based on this.
Where is the variable voltage portion, I must have missed it.
