Thread: New DC-DC power supply option!

for that kind of pricerange, i'd rather shell out the cash for Jeff's Psu ( I think its smaller)

well i won't say its a steal, but it does come with it's own delayed shut down timer up to 1 hour, automatic shutdown when your battery reaches low voltages (won't kill your battery), and its 90% efficient..

true, the auto shutdown would be a nice feature (something i need to look into for moding the sproggy), but for the cost of that PSU, i can build 3 sproggy kits and shut down controllers. Plus I like the idea of doing stuff myself, kind of the point of this hobby, isnt it?

I used PC Power and Cooling's Supply.
(About $130 delivered and it comes with some freebie extra's)
It's a 1U configuration.

Although it's not small like Sproggy's, and more expensive, it is 100 Watts and built very well.
I've been buying from PC Power and Cooling for over 10 years and have yet to have problems. Still have one of their old AT power supply's thta is 10 years old that we still use for testing.

I have tested it with a 12volt AC to DC power supply I built with an ECS mobo with a 500MHz Celeron and old 2GB hard disk as well as a new Maxtor 20GB 5400RPM, modem, all integrated stuff.

After the initial power up surge, it only drew from 3.8 to 4 amps on the power supply's 12V Input.

Again, it's big, but you can get an identical AC 1U version one for quick disconnects to bring in the house.

That's what I plan to do anyway.

someone that is really good at building homemade psus could buy this one and get some really good ideas from it on how to make the same psu smaller and more cost effective... jeffs is almost perfect... the only thing i like about this one better is the shutdown controller already being built in. it sounds like its more plug and play ready to go. but for that price I do agree Its worth my time to go with jeffs designs and build it myself... i mean $180 can ALMOST build an entire carputer, for some it can build theres and then some.
