I want to convert a PSU into a powersupply fgor my work bench that i can fit underneith but i want it to chuck out quiet a bit of power between 15-25 amps is it possible with a PSU I plan on having it screwed under my desk and then have a small box that is screwed to the top of my desk with outputs on it. If so what sort of wattage PSU will i need and can anyone recoemend me a cheap one on ebay?????

we made ours from a QTEC ATX PSU (or q-tec), no bulbs, no resistors, runs our charger a treat.

let us know how it goes Ash.

Try ebuyer http://www.ebuyer.com/product/102994, 30A on the 12v rail.

400w minimum, mines 500W look on ebay for the best prices

also check my topic on these, theres a link in there to a page on wikipedia which I mainly followed, and mines working fine *touchwood*

Ok thanks for he help ill keep my eye out on ebay and have a look about for some i have a firend who owns a small shop he sells this sort of stuff so i may pop in and see if he will do me a good deal on one.

But it is blue, i think a blue led in there, and that thing would look the shizzle:D


Crack is wack:confused:

This is going to be messy....... :p:p

why not get a normal psu and put a blue fan in it.

A

Whats "normal" ash?

and its sixty quid, and no ins and outs !!!!:wtf:

just buy a propeak 20 amp. 5 amps more than you will have, some taky blue led's and a tin of blue paint and save you money

Just made one up a few weeks ago from spare bits for a total cost of £0.00 - and it's excellent!:thumbsup:

I loaded the 5v rail with an old automotive bulb I had around and it puts out about 12.5v on the 12v rail consistently.

On/off switch was from an old Tamiya MSC, I think. Binding posts were scrounged up from somewhere, and the PSU was discarded by a friend who was upgrading his machine.

have converted a few of these power supplies, all work well. if you can find older atx ones you only need to load 5V rail, i use 12v 50w domestic halogen spot lamp bulbs mounted with a tool clip inside the case. if you can find an old AT power supply anywhere (not easy!!) then all you gotta do is plug it in and switch on, no loading required
