...I researched the net and opinions seem to be divided.
You need facts, not opinions. <g> In the Power Supply chapter of my book
you'll see that the EPS/EPS12V
24-pin main power connector (originally introduced in 1998) was subsequently included in the ATX12V 2.0 (and later) specification
starting in Feb. 2003.
In other words, any modern PSU meeting the ATX12V 2.0 or later specification will include a compatible 24-pin main power connector. Scott.
