ESP12V PSU with ATX?

[Carson Dyle]

I found an old Antec True550 EPS12V 550W power supply hidden among some old parts.

In addition to a bunch of 4-pin peripheral connectors, it has:

24-pin connector
4-pin connector
8-pin connector

These are all solid connectors that can't be split.

Probably poor efficiency and there are no SATA power connectors, but would it be usable in an emergency with an ATX motherboard?

Should be fine to use. You might need some molex-to-SATA power adapters, I always keep a handful handy.
