One would only start the machine intermittently. The other one fine...so I have a total of one spare supply. I did find a bad cap in the intermittent supply, but since it's an Antec, did not bother to replace it. I disassembled it and will use the parts in a junk sculpture. I make a lot of weird art using junked parts that I've been saving.
