This article is from the Apple II Csa2 FAQ, by Jeff Hurlburt with numerous contributions by others.
It is an external power supply, usually a surplus PC unit, which connects to the Apple II via a heavy-duty cable. My IBM-style power supplies generate the same voltages (+5v, +12v, -12v, - 5v) as those required by the Apple II. But IBM-style power supplies deliver 150-200 watts of power, more than twice the weak output of the standard 60 watt Apple II power supply. Thus, problems associated with weak power (screen freezeups, crashes) in the Apple can be reduced or eliminated by using an IBM power supply on the Apple. With a strong IBM power supply, you can fill all your interface card slots or add extra disk drives without overloading the power source. Recently, I have offered these power supplies for Apple II: IBM 150 watt power supply, soldered to 5 ft cable; choice of either IIgs or IIe plug. $27.00 plus $5.00 UPS shipping ($8.00 shipping to Canada) Cable-only: connects to IBM power supply at power-points P8, P9, and Molex-4. Allows you to connect the IBM power supply you already own to an Apple II (Specify whether IIgs or IIe plug is needed). $14.00 plus $3.00 priority mail; To Canada: US$4.00. Above cables made with heavy duty wires (AWG-18, with 600v insulation; color- coded. All power supplies and cables thoroughly pre-tested prior to shipping.) 200 watt power supplies occasionally available at $3.00 extra cost, but an extra 3-4 weeks must be allowed. Eight page illustrated instruction manual sent with each order; also the manual is available on self-booting text-file disk. Faster service! During the past month, users have had to wait 2-3 weeks from payment to shipment. More power supplies have arrived, and I have ordered the cable components in larger quantities, so through the remainder of the summer I expect to ship the orders within 4-7 days.
