View Full Version : How to determine type of psu?

05-10-03, 12:21 PM
Will I be able to use the psu and/or case from an old 486 on a Zida BX98-3D?

I was told that it depends on if the psu and case (which are normally the same) are AT or ATX. How can I determine this?

AT is more square then ATX. Plus wid AT you will prolly see some ISA slots to

If its an at case then no you cant put an atx board in it without a lot of modifcation. If you look at the harness comming off the power supply an ATX ps will have a rectangular plug with 2 rows of pins( total of 20 pins) the older AT supplies only had single rows of pins(6 pins in each connector) and there were 2 connectors for the mobo that went side by side.

Thanks, trying to determine now.

if its an AT mobo the power connector will be longer and the AT psu will have 2 parts to connect to the mobo for power, to fill the longer connector on the mobo.

if u have trouble, post a pic we can tell ya.
