Odd size desktop power supply?.

[tony sayer]

We have a rather odd specialist desktop PC that got a knackered power unit. This wouldn't normally be a problem but on this series of units they had a slightly lower in height power unit.

Where most all of them are 140 mm high and 85 mm wide and around 150 mm deep (front to back) this one is 120 mm high! (85 x 120 x 150). A standard one will stick out of the top of the case which isn't required;!. Anyone know what they are called and know of anywhere in the UK you can obtain one from they have the normal fixings and IEC input and output lads just need this reduced height!..

cheers..

Hi Tony

probably best to search (on eBay etc.) based on the make/model of the PC, I'd have thought, eg. 'Fujitsu Scenic S2' (one desktop machine I know with an unusual PSU).

One possible answer is: angle grinder. I've seen plenty of PC PSUs where the innards don't occupy the full height of the box. Take care to avoid any metal filings, eg by decasing the pcb and reinstalling once cut. As many cases are made as 2 Us, it will very much affect the case reassembly, but it can all be patched up with duct tape.

Along those lines, wouldn't it be easier to simply transplant the pcb?

Probably one of the five variants of SFX/SFX12V PSUs; if not, one of those will fit although you might need to drill one or two new fixing holes at different centres.

How easy they are to come by...I haven't looked.

What wattage?

[Tabby]

Maybe, the only issue is the mounting points probably wont match. It would ease fan mounting.

Dell boxes can be like that. You seem rather coy on naming the actual make/model!

Go on google / fleabay with the make/model, and you will usually find a replacement.

[Jeff Strickland]

Why don't you try plugging the Model Number into your search engine's Search Box?

I need a power supply for a Princeton monitor that I own. The model number of the power supply is HASU05F. Plugging that into the Search Box of Yahoo! gave me a host of hits, some on eBay. The supply I need can be bought for $10.25, shipping included.

[tony sayer]

Yes well, there simply isn't one this was made up out of component parts a while ago now even the power unit hasn't got anything recognisable on it!..

Bin there haven't found one!..

[tony sayer]

Now thats the sort of answer only someone on UK DIY could give!, but it seems it might be the simplest one as fortunately theres a bit of space over the other side of the box so put it there and extend the IEC input lead connector we have lot of =panel mounted ones around so job effectively done:)..

[tony sayer]

Doesn't quite seem to fit that description..

Dunno, absolutely no markings on. Seems I will now take another supply and fix that over the other side of the case and extend that mains input lead etc..

Cheers all the same..

Do you have a digital camera ?

It's possible to post a picture of your "puzzle" on imageshack.us (being careful to tick the box to prevent them from reducing the resolution).

Are the connectors standard AT ? Or standard ATX with 2x10 or 2x12 for the main power ?

To give an example of how big a picture you can post, this is a benchmark I posted some time ago.

could take pictures from several angles, and then glue them all together into one picture.

I think one of the old PC's her a had a supply of similar dimensions. These things are mass produced to standards so the OEM's can just pick what they want and bung it all together. I suggest having a google along the lines of power supply size or dimension and seeing if you can find what something that size is coded as. Some one has already mentioned a few codes, of course even if you know the code if this is an old machine you might not be able to find one to buy...

[tony sayer]

Well I took the "Angle grinder" approach as suggested on UK DIY as it was prolly quicker!. Gutted the old unit in fact It would have been possible to transplant the board from a new unit except that new one had a nice large cooling fan. So chopped all the old wiring and soldered the mains plug now "chopped off" other end of an IEC kettle lead direct to it via the switch, was arranged to switch the neutral so now swapped that around to live!".,

Grommeted and tywraped the main cable coming out. Installed the new supply fitted well right over the other side of the case made up a small bracket a couple of self tapper's which hold it fine, wired and now back in service not that "neat "an appearance but very effective:

Thanks to all who replied:)..

Cheers...

Is fixing it not an option? The same few things cause most of the faults...

[Paul Bird]

Given the apparent complexity of a SMPS, and the fact that you can't learn much when it's not running what is the usual diagnostic approach? Blown caps, burned resistors?

PB

[tony sayer]

No service info at all, not even a circuit diagram?. Where would you start?. Caps possibly but the quality of that thing looked cheap anyway the new one much better:)..

[John Williamson]

I see it's too late for this time, but if you Google for a 1U PC power supply, you get items like ths one from eBay:-

one is 150.0 x 40.5 x 81.5 mm

[Dave Plowman (News)]

I obtained a PC PS from CPC - long and thin rather than the more usual almost square type - and fitted it into the Acorn PS case. The cost was so low it was not worth the bother of fault finding the original.

Could you do the same sort of thing?

[tony sayer]

As mentioned now Dave all dun and dusted, took a standard sized one and put it over the other side of the desktop case!..

Point take re CPC pity their website is that awkward to use sometimes..
