I ordered a new system from Scan that came today, and upon building it noticed the 24 pin motherboard connection from the PSU would just not go in properly. The PSU is a decent Corsair one so it's not a cheap build, but it leaves a slight gap between the socket on the board and the 24pin plug.
I then reached the cable over into my other PC plugged the 24 pin in and the other 4 pin connection, powered on fine. However with this new motherboard it does not like going in what so ever, it's an MSI 970A-G43. Is it unheard of to encounter this problem? Because I got advised if I want to return it, and it ends up being fine they will charge me the courier collection fee and the testing fee of £35.
