"Usually" a computer drawing close to 600 watts continuous will have a very good RFI free PS of 750 to 800W capacity. Of course much depends on what else is in there, how the I/O is handled, and the cabinet.

If they are talking thousands of machines and saving a buck here and there and doing things on the cheap, it can be a disaster.  If that's the case, document the RFI, document the equipment used to measure the RFI and the procedure used.

Call the ARRL and ask about monitoring said RFI.  Their help and recommendations carry a lot of weight with the FCC

Given the open construction and the relatively high power it's not
surprising this was an RFI source. The model mentioned in this story
draws 560-590 continuous watts and is typically powered by a PC ATX
power supply.
