FWIW, I've also used a ATX power supply to power an XO-1, but stopped doing so once I discovered why the XO-1.5 would run from it: Being a cheap model, it regulated only the 5V rail, so the 12V rail dropped down to 9V with a switched-on XO-1 connected to it. The XO-1 barely coped (the power light started flickering some time ago, probably due to the power supply aging and delivering an even lower voltage than before) and the XO-1.5 (without MPPT ECO) didn't like it at all (whining noise, LED off).An ATX or AT switch-mode power supply attached to a set of nine laptop charging cables. The power supply is being used as a 12V DC regulated source. The original PC power harness cables have been removed.
Summary: If you're trying to replicate this setup, make sure your PC power supply regulates the 12V rail (just hook up some load and check the voltage).
