Just received my nice new Corsair HX 620W power supply... its one sexy beast (well for a power supply anyways) 
I've installed it on my system and everything is working ok - but as I was installing it I was wondering something...
The modular sockets that the cables connect into - are they split between the 3 x 12v rails? I just thought that if they were specific for each 12v rail (say 2 sockets for one rail, 2 sockets for another rail and 2 pci-e sockets on the final rail) it may be worth knowing which is which so that I can plug them in and spread the load evenly between the 3 rails?
Anyone any ideas?
