Old Technology PSU

Hi, I'm new to the forums, and I couldn't find anything pertaining to my problem.

I recently got an NEC Express 5800/260 case, I wanted to use it as a case for a standard ATX computer, and was having an issue with the PSU.

It has 3 ports for plug-in PSU's and came with 2 PSU's, I have never worked with anything like it seeing as it has a PSU adapter board of some sort

The board seperates the 3 PSU's for 3 different applications, one PSU port goes to a 22 pin connector, one goes to what appears to be a 24-pin atx connector, and one goes to 3 hard drive/cd power plugs and one floppy drive power plug.

The main problem is that the 24-pin ATX connector is not normal in the wiring I have seen,
It has 13 red wires and 11 black wires, pins 1-11 are red, i believe those are the pins, the row farthest from the latch and the one farthest left of the latch of you have the wires facing away from you

I was wondering if anyone had any knowledge of whether they would be the same wiring simply with different color coding or if it was something specific to that case and motherboard. Any help would be great, and if you know anything about the Express 5800/260 I'd love to have a chat

Thanks for taking the time

Well since you are new you will first need a Welcome to the Computer Forum! http://www.computerforum.com/70672-official-welcome-thread.html And be advised to be familiar with the http://www.computerforum.com/52038-forum-rules.html

You must like dealing with antiquated equipment headed for a museum. :P That server case was first seen in 1994. One manual along with some information on the wiring is seen at http://www.necel.com/nesdis/image/U15104EJ2V0UD00.pdf

The last version runs Solaris as the main OS with the dual PIII 550mhz mother board. SUN Microsystems has some information on that at http://www.sun.com/bigadmin/hcl/data/systems/details/280.html
 
Thanks so much for the help, but unfortunately that manual appears to go along with the motherboard, the main item Im not using

I actually plan to use a new atx motherboard etc, and basically build a pc using this case.... Unfortunately Im not quite sure about the power cage's compatibility along such lines

If you or anyone else happens to know anything about the cag001 Power Cage or perhaps another power cage that would be adequate I'd love to hear

Thanks for the help

One place for support on NEC power cages as well as replacements can be looked over at http://www.fixya.com/support/nec/system_power_supplies since you happened to mention that.

For seeing a new build put together with an atx board the common approach would be to simply choose an atx case unless you are planning to custom modify that one there for show. You will probably have to plan out a custom mounting scheme for the new board as well as mounting a new power supply capable of running the eventual hardwares to be added along with that. Those were proprietary builds back then with their own ways of mounting things.

You should just go out and get a new case that comes with a PSU inbuilt.

Most supplies that are thrown in along with cases are generally low end "foobar" and not worth the time bothering with. The best idea there for any system builder is to buy the supply separate according to the type of case being put together and the quality of the supply itself. When you get the supply along with a case you get what they thrown in. :eek: "aw crap it quit in 2 weeks!" is no surprise here.
 
From what I've gathered the two slide-in psu's are 300w each, I would love to get a new psu and mount it in there, but the style of the case is very far from acceptable

I love the case seeing as its nothing like anything you get these days and thats why I would prefer use it and not a new case, it has 2 external 5.25 bays which i plan to use for a dvdrw and a dvdrom, and one external 3.5 which I plan to use for a zip drive, but the nice thing is it has I believe 7 internal 3.5's for scsi, but Ive removed the scsi board and a standard drive fits in there just fine, I was thinking about pulling a motherboard mounting tray and fixing it to the case to mount a new mobo but the issue im most concerned about it is still just the psu

I would like to find a different cage to work with atx style with enough peripheral power plugs, and Im not worried about the psu's not being able to handle the load although I would like to get something newer to fit the form



Thanks




And as for the site you sent me (http://www.fixya.com/support/nec/system_power_supplies)
I've already been lead there a few times by google

The power cage I have is the NEC Fuji Cag001 and I also have two NEC P3R001's

The issue is that a new cage board would be perfect

For custom mounting an updated supply you may have to take an old case apart for the rear of the frame in order to mount that somehow so that the supply is still at the original opening for heat exhaust. That will take some work there with some common hand tools and a power drill.
 
Ok, All the help thus far has been appreciated

But I think maybe somewhere I misworded something,

The case and PSU are the only item's I am interested in

The only thing I would like to know is if anyone knows of a replacement power cage for the CAG001 that doesn't have the same power connectors, the CAG001(The Power Cage I currently have) does not support many items, although it utilizes two 300W PSU's

The entire Power Cage come's out very easy, Mounting a new ATX PSU would not be difficult, the biggest part would be working a sheetmetal plate to cover the empty space seeing as the difference in size.

The question at hand though is if anyone knows of another Power Cage

I have not been able to find a replacement other than the same model and This is what I was asking for help on

Thank you

Got time to go through a llloooong list? http://www.pinnaclemicro.com/skupages/sku8011.htm

Another replacement part vendor is EZSystems.com. http://www.ezsystems.com/skupages/nec_002.htm

When you simply need to locate an item you run a web search to find any vendors still carrying replacement parts like these here or used systems you can savage parts from. The alternative would be some serious metal working to make up a custom made cage that fits a single supply while still covering the opening seen.
 
Your main problem now will be either ordering an original factory type replacement leaving the gap for the second supply or basically doing of that infamous custom metal working to jerry rig something that works. I would tend to think that the factory replacement and a custom plate would be your better option there unless another replacement centers a single supply and blocks the excess at the same time. But the mounting would still be not quite atx standard at this late date. Try the links to see if an original is available.
 
If you have an ATX motherboard, you'll want an ATX power supply. Simple as that. Whether it will fit right is a different matter. :P
