I don't why they would call it that. If it matters any, the old large connector type keyboard connector is called an "AT connector" since I guess that's because those type of keyboard connectors were for AT mobo's, therefore AT power supplies. The other type of non-USB keyboard connector is "PS/2". If that tells you anything. -Clint
God Bless Clint Hamilton, Owner http://OrpheusComputing.com http://ComputersCustomBuilt.com ----- Original Message ----- From: "Roger Carnell" Thanks Clint, I have the ATX type now and have had AT types in the past. I just haven't looked at cases in awhile and saw some that actually list the power supply as a PS/2 type. Didn't know what the heck that was. I wonder why they started calling it that? More mind games... Roger C. ----- Original Message ----- From: "Support-OrpheusComputing.com" No such thing really as a "PS/2" power supply. There's AT and ATX. Yes, there's a huge difference since a different mobo is needed for each specific type. An ATX mobo needs an ATX PS, and an AT mobo needs an AT PS. The AT also needs an external power switch, where as the ATX uses a "soft power switch" integrated into the ATX mobo. The voltages are also different in that the AT has no 3.3v, 5vsb. I don't have one handy now to check but I think maybe the AT also doesn't have the -5v & -12v, but I can't recall. Externally, the dimensions are about the same within a few mm for **typical** AT & ATX supplies. There are some proprietary designs used by some PC manufacturers. AT mobo's are getting very hard to find (and also the supplies). I haven't seen any new ones for the past few years, they've all been ATX or the new BATX. -Clint ----- Original Message ----- From: "Roger Carnell" Hello, Been looking to buy a new case lately and see that some have a PS/2 power supply. I did a little reaearch but am not seeing much for difference between that and the ATX supply. Is there any real differences? I thought at first that they may just be smaller but I'm not sure if that's the case. Any ideas? Thanks, Roger C. ============= PCWorks Mailing List ================= Don't see your post?
