"converting an ATX PC power supply"

and pages of good stuff will turn up.

Here's the first two I found.

Hope this helps.

thanks..i've read all those threads...but i had success last night....was just a matter of tieing the grey to the green and then to ground with a resistor in the loop on the red and ground..worked fine after that...thanks for the links!

Has anyone ever tried connecting something like this in series on the positive terminal to impliment inrush limiting? I am wondering if doing so would allow one to connect the charger after powering on the PSU instead of having to connect the charger before turning on the PSU?

This new unit has smart IC for the fan speed installed...
Someone please correct me if I am wrong, but hasn't this model been around for a while now? I think the fan control in it is nothing more than the same as shorting pins 4 & 8, in the DPS-600PB version which does slow the fan down considerably but isn't true temperature control, am I right?

Thanks xandrios. It looks like it is the same as connecting pins 4 & 8. I am working on a true temperature controlled circuit that can be used for the DPS-600PB and possibly other model PSUs later on down the road. It's not quite ready yet. I will post the PSUs up for sale here when they are. First I need to finish building a variable dummy load that can handle 1200+ watts in order to test the fan speed and internal temperature at various current levels all the way from 0 to 50+ continuous amps so I can fine tune the circuit. I am making it so the fan does not even come on until it is needed (i.e. until the internal temperature begins to rise). I just want to be sure that it will go on fast enough when the temperature rises so that it provides proper cooling while at the same time staying as quiet as possible given the operating environment at the time.

Hi

looking to use two of these in series, it would appear the -12 is only connected to ground via the output plug fixing screw. can anyone confirm this please.

Thanks Robo1981.
It looks like the OVP mod gave you the extra power you needed.

Hm, interesting BrushlesHeaven. I ordered one and will check it out. They are pricey though compared to the DPS-600PB and hard to find, those are two major drawbacks. I didn't see any of them on eBay at all.

It looks like this will be the replacement to all 600PBs soon.
Not too many around but they are very cool. Do not need fan mod to be installed anymore and also the fan will spool up on high current draw so now they understand the draw and temperature :-)
I was playing around with the sensor by worming it up and cooling it down and it works great. They are much quieter than 600PB...
Fan location is now low on the connector plate. Easier to install output connectors, nicer too, more solid install...
I like it...

Cool. See, not to say I told you so to all the doubters out there but, well, I told you so ...I knew the tempurature control fan was a winner idea, now they are just catching up to me (kidding of course.. the "new" ones have actually been around for quite a while). Soon I will have my mod ready for sale and it will also have a tempurature controlled fan which will be silent when fist turned on. Hopefully people will like it. I've already put a ton of work into it. I think they will.
