Ridiculous bids on GetAFreelancer.com

Why building, if you can buy it? Would cost about $38, maybe cheaper on eBay:

If you are crazy, you could integrate it into the computer case.

I'm surprised that someone hasn't created a PC power supply that's UPS-ready... 12V battery input (13.3V to 15.1V DC input)... eliminating one conversion.

Sure, but the question was whether it is possible to redesign an ATX power supply in 2 to 7 days to work from 12V DC for $50? Using an external DC to AC inverter doesn't qualify! :) Besides, a 450 W (which is more typical of todays PCs) inverter will probably cost a little more than $38. I can see it only possible if one had a ready solution in his pocket, but who would be willing to sell his hard earned experience for $50?

People have. I do not know this company, was just the first hit:

I've seen them cheaper, too. Very practical if you must mount a "real" PC inside a vehicle. Also comes for 24VDC (European trucks) and 48VDC (industrial). A client had to do that, mount a major system that could not possibly be operated from a laptop inside a huge semi-trailer. My job was the analog stuff. "Ahm, could we make the interface bus 45 feet long ...?"

it

Is the $50 for the work, or for the cost of the power supply?

For the work!

Yea, they have been around for some time.

What's really neat are the mini-ITX power supplies, just a tad bigger than the Molex power connector.

Cheers

I very much suspect the people offering to provide the solution are just going to mount a standard, cheap 120V AC inverter on top of the power supply, as others here have suggested.

The purpose-build "12V to standard PC motherboard connector" power modules are pretty neat though... if not exactly the cheapest route.

I was thinking that someone had already "scratched an itch" and could see that for a marginal cost of zero to forward a file, he could get $50.

Hell, i will promise to do it the very day after i cash your check!

Why bother when you can buy them off the shelf for less !

But first you'll have to wire $12 to Nigeria to cover fees :-)

No problem, just buy a 12V to AC(whatever) converter for 26Euro19,

These supplies show up in surplus stores all the time. I gather they are pulls from junked datacenter servers. Usually 48 volt input, i.e. a series connection of a few gel cells.

You may want to wait for the check to clear before making promises.

Well, if the switcher part works even a little with 12 VDC in, then the guy's $50 buys a couple of snips with wire cutters and soldering wires from the AC input to the switcher part... A sticker warning about connecting the bomb to mains, another $50 :)
