PSU Faulty? How to test

Afternoon all,

After getting all the parts together, I put together a new PC but it wouldn't post. The motherboard debug shows it as a CPU fault. After going through all the usual suspect; reseating CPU, CPU cooler, 1 RAM stick at a time in each slot etc. I tried my old PSU and the new system posts. Trying the new PSU in my old PC and it won't post (again showing CPU fault).

I think it's fair to say it is the PSU at fault and, due to the CPU fault on both systems, my suspicion lies with something to do with the 8 pin EPS. However I've used a jumper from my watercooling days and checked the pins and both 8 pin and 24 pin are the correct voltages.

So I'm a little stumped but I'd like to do what I can to prove it is the PSU before going through the RMA process but not sure what else I can really test without buying a specific PSU tester.
 
I think there is enough evidence there to justify an RMA. 7 Year Warranty on Superflower IIRC.
 
Could be something as simple as the power good signal being out of spec, meaning it has the correct voltage just not in time to meet the ATX specification.
