Questions about Seasonic Prime TX-1300 ATX 3.0

Hello, Following the recent update to the ATX 3.1 standard, Seasonic began replacing these with the new 12V-2×6 connectors. However, we seem to have the preceding version in stock, it might take some time before we get the updated version.

Digitec gave me a CH cable for free, the only one they have in their range for the C20. However, this cable was unusable as it was very loose and threatened to slip out of the power supply unit. Neither Digitec nor any other online retailer had any other CH cable that I could have tested. I have learnt that this is because the specifications for C20 plugs are not compatible with the standard Swiss socket. C20 is therefore only permitted if the cable has a circuit breaker. This is of course completely nonsensical for the small amount of current. So in the end I simply bought a German cable with a Schuko adapter for the C20 plug, which works perfectly and sits firmly enough in the power supply unit.
