EI Systems Desktop

I have a cient who needs to replace a power unit on a EI Systems computer brought from pcworld.co.uk.

However i do not know anything about EI Systems - they dont seems to have a manufacturers web site in the UK.

However i just wanted to know if anyone could give some information on EI Systems, do they use specialised power units in their computer. MY client has been told that they will have to buy a special small power unit which costs more - im trying to find out if this is the case and also provide them with a replacement instead.

However i have not seen the computer and cannot check whether the power unit is a standard unit or not.

Does anyone know  -i cannot find any information on the internet about this.

Generally with computers do you only get two sizes of power units - the standard ATX and mini ATX... not including the small form factors like dell opti-plex.

Thanks any information will help ! ;)

I think your client is referring to an EZ computer.
These were barebones retail units sold in the UK via Maplins stores. They were (relatively) cheap and consisted of a CPU, m/board, case and PSU. However, the unusual thing was that the PSU was external and seperate from the rest of the machine - a bit like a power transformer for a printer.
The Maplins brand had "EZ BUDDIE" written across the front. This is what it looked like:

 http://www.maplin.co.uk/module.aspx?TabID=1&criteria=EZ%20BUDDIE&ModuleNo=48614&doy=3m5

Getting hold of a compatible PSU will not be easy. Your best bet is to contact Maplins and see if they can help.

Hope this helps.

Good luck!

Hey phototropic,

thanks for the link and info. No i dont think that the client meant EZ, they are right in say it was an EI systems computer.

http://www.pcworld.co.uk/martprd/store/pcw_page.jsp?BV_SessionID=@@@@1028203987.1146722410@@@@&BV_EngineID=cccdaddhjjfejedcflgceggdhhmdfho.0&page=SimpleSearchProducts&low_bound=0&up_bound=0&criterion=ei%20systems&AtimeStamp=3324121455

If you check the link it should show you the EI systems sold at PC world. Or you can go to pcworld.co.uk and type in EI systems in the search bar and it will return them all.

Generally with computers do you only get two sizes of power units - the standard ATX and mini ATX, or is there one standard size ? Im not sure ?

Most pcs these days take a standeard ATX power supply.
Some older models (eg.Tiny) take mini or micro ATX, which is smaller.
Some. like Sony Vaio, will only take a special generic PSU, and surprise surprise, only Sony supply them. And they won't sell one to you!

If your client's pc takes "a small PSU" it will most likely be mini TAX.
Maolin have a couple:

http://www.maplin.co.uk/search.aspx?MenuNo=780&MenuName=Micro%20ATX%20PSU&FromMenu=y&criteria=Micro%20ATX%20PSU&doy=4m5&worldid=4

And so do Komplett:

http://www.komplett.co.uk/k/ki.asp?sku=303993

From the look of the picture in the link, I would have thought the EI pc would take a standard ATX>
Mini ATX are more expensive and much harder to find (Ebuyer don't sell them).

Check out the spec with PC World before you cough up £39:99!!!

Good luck!

Cool thank you will talk to my client, and find out more information about when they got the PC and also check it out with PC World..


Stragne why dont eBuyer stock even one of the Micro ATX's ?!

Anyway thanks, will post back with what happened :)

I think Ebuyer see micro ATX as an antiquated form factor.

I don't really know of any computer manufacturers who make machines which use them.

The Tiny ones were 180 watts, which is minimal (and laughable!) Modern pcs have a much greater power consumption, with fans on graphics cards and huge hard drives.

If your client's pc does use a micro ATX PSU, you might want to look at the power issue, although there is not a lot you can do - standard ATX simply will not fit!!!

Good luck!

Hello,

It seems like this was an mini ATX and coincidently another one of my clients who brought an emachines PC (also from PCWorld) also had their power unit fail and it also another mini ATX power unit. Have source two great ones for only £20 at Maplin Electronics !

Thanks for everyones help, looks like PCWorld like to be different and sell some of their computers with MINI ATX's ;)

Thanks

gisvpn,

Can I help you any further with this, or is your problem resolved?

If it is then you need to close this question.

Thanks.

Hey phototropic,

Yes you may be able to help, the micro ATX power supply is a strange size. From what i can see the standard width for a micro ATX is 125mm (120cm). However the width of this PSU is 85mm (8.5cm) !!

Here is the actual model number (ENP2222B) for the PSU and some links :

http://www.enhance.co.kr/product/ENHANCE%20POWER%20DETAIL%20SPEC/mechanical%20drawing/enp2222b-m.pdf

Strange is this a specialist PSU at all ? I thought that there would have been a standard Micro ATX size ? ;)

Thanks

gisvpn,

Sorry I didn't get back to you last night, there was a powercut in the middle of my typing a response!

If you look at this:

http://www.directron.com/psu.html

you'll see it says:

    " ATX: 6x3.5x5.5", HxWxD. Most common. Uses 4 mounting screws.
Mini-ATX: 5x3.5x5", HxWxD. Rare size. Uses 4 mounting screws. Can be used in a regular ATX case, but often not the other way around.
MicroATX: 5x3x4", HxWxD. Use 3 mounting screws. Not interchangeable with ATX or miniATX.
Flex ATX: Even smaller than Micro ATX. Various sizes according to case specs; often not interchangeable.

Use the data above to determine if a particular power supply would fit your case."

Maplins, Komplett, etc., all sell MICRO ATX PSU's. I don't know of anywhere that sells MINI or FLEX (?never heard of that before)

If your client's pc uses an unusual form factor PSU, you have two choices:

i)  Try to find a secondhand PSU that will fit. With MINI ATX that is a long shot;
ii)  Offer to build the client's pc into a standard ATX case. A standard  PSU + ATX case will cost about £35:00, plus the cost of the time it takes to transfer the components. This will not be that much more than the usual £39:99 for a MICRO ATX PSU! Plus the client will have easier access to components and easier replacement of parts.

I hope this helps.

Good luck!

gisvpn,

Has this helped to resolve your problem?

Did you find a PSU or did you go for a rebuild?

It looks like this is a flex ATX one  - very hard to find especially when the manufacturer is not in the UK and does not have a proper web site ;)

thanks for all your help. I think im going to offer to transfer into a Mini or normal ATX box. !!
