Vintage Astec AA12150 63 Watt Power Supply For IBM PC/5150s And Compatibles
Item History & Price
| Reference Number: Avaluer:911881 |
For sale is a vintage, Astec AA12150 63 watt power supply for IBM PC/5150's and compatibles. It is
clean inside and out, and has been tested several times on a 12mhz XT motherboard with an assortment of cards, along with a floppy drive and a WD25 (21m 5"FH MFM HD) plugged in and booting up.
Note: I am assuming the AA12150 is 63 watts. Whatever wattage it is, it performed robustly with the
devices mentioned above.
The power supply is heavy-duty, as well as its fan,... which is so quiet you won't even know it's running, other than the smooth flow of air through the rear vents. The rocker switch has a strong, firm feel in turning the power supply on and off.
There are two power connectors for drives. One is 11" and the other is 10" long. Both cables should
reach drives in both bays fine. However, there are scenarios where a "Y" cable might be required. For the harddrive, it should always be directly attached to one of the two power cables (suggest the 11" one), for the benefit of maximum draw without interference from another drive. If two 5.25" half-height floppy drives are adjoined in the other bay, or a 5.25" half-height floppy drive and a tape backup drive, then those two drives should share the "Y" power cable.
Note: Most likely, the 10" power cable used to be 11". As can be seen in the last photo, a previous
owner patched the cable for some reason, which shortened it. In my testing of this power supply, this cable is as solid as if it were original. I would not hesitate using this power supply in my own PC/compatible system if I had one.
Note: If reaching towards the rear right of the PC in order to turn the power supply on/off is difficult, use either a power strip or a power center in which the power supply is plugged into. The power supply's rocker switch would then be left "on", but the PC controlled by the power strip or center.
This power supply is being offered in "as is" condition.
Please email me for any other questions or considerations. Thank you.
