Unknown PSU connector

post #1 of 9
Thread Starter 
I got a rackmount chassis from a guy I know. It came with a 300w Antec PSU, but I can't for the life of me figure out what the motherboard connector on it is supposed to be. It's got a handful of molex connectors, and a floppy connector, so this last one must be the motherboard one...or are rackmount chassis only supposed to hold drives and nothing more? I have a picture of one there, but actually there are two on one cable, and yet another on a separate cable. I included a few shots of the chassis and two removable enclosures which I also can't figure out. Someone help!


The unknown connector...for old motherboards?

What the hell is the second one for?


Is this for SCSI drives, or what? I've got two for the chassis, to hold what looks like a total of 6 drives.


Shot of the chassis and fan tower, which screws into the middle.


Better shot of gutted chassis...no mobo holes in sight!

It is a 6pin aux connector for AT motherboards.

Nice case! You could just replace that fan tower with a gtx480 radiator and you'd have one sick internal W/C'd beast.

As far as those connectors go..they are only 6pin, so they have to be the secondary connector, or ATX plug..if they go to a mobo..I have a couple of those connectors on some older PSU's, just never actually had hardware that used them. Maybe an old AMD atx plug?

AT form factor lol...dates back to the 80s. This is the form factor that preceded ATX.

Ok, so it's a wickedly old PSU. Well, I would totally be willing to just stick another PSU in there, but this POS - excuse me - PSU has one of those power switches that toggles on and off...the kind with four wires going into it. I remember them from old skool computers. I guess I'm going to have to do some modding...this is going to end up being a dual Xeon system, since the guy I got them from is looking out for the next Xeon CPUs and mobo he gets at.

I just remembered this one time when I took apart a system I found at the dump. It had those AT power connectors (I just found out that they're called the P8 and P9 connectors), and the mobo was fastened to the case in some crazy, '80s way, which explains the lack of holes for mobo standoffs.

Jesus! If this PSU is as old as you all say it is...it must have been wickedly powerful for its time! It's 300 watts!

EDIT: Haha, good idea with the gtx480 radiator...it would probably fit perfectly! The only problem is that this fan tower screws into the middle, which means the "hot" air would be traveling through half of the motherboard.

You could 'vent' the floor and mount fans there to blow fresh air up into the rad..or just mount another gtx480 at the bottom of the case..and run them in series...ohhh I love dreaming!

All I need now is $300...

I'm going to mod this case to hell, and it may become the applied piece of my senior project, which may be about Folding@Home. All I need are the Xeons, a compatible motherboard, and some registered ECC DDR RAM...lol. If I end up doing this for my senior project, watch out for a worklog

Yeah the other plug on the back of the PSU is to plug a monitor into, so you don't have to go through your mains supply.
