I have a Micro-star 945P MS-7176 ver:1.A mainboard and a North Q 'NQ4775' 400w psu. On assembling the various bits & pieces on the mainboard, I have come up against a problem. The main 24pin plug fits ok but according to the supplied mainboard manual, there should be a power supply fitted to 2 other sockets as well, namely: JPW1 (8pin) and ATX2 (4pin). The manual states that all 3 connections should work together to ensure stable operation of the mainboard. The problem is supply cables from the PSU. There is not a cable with an 8pin plug on it for the JPW1 socket. There is a cable with a 4pin plug but no socket for it on the mainboard. Also, can I use any of the other power cables for the ATX2 socket?
