Boot problem with GV-N460OC-1GI (GTX 460 1GB)

Yes, it is a real problem and a Single Rail on a PSU is definitely a better solution for the higher end graphic cards. But, as you also said in your earlier post, if BIOS was written a little differently, maybe this wouldn't be such a big problem.

The increased power needed to fire up the newer PC systems is one of the many reasons that Dark Mantis and I are always banging on about the PSU and asking what make and model is being used.

Thanks for the update, it is much appreciated. +1 to you

The PSU is probably the culprit because as you said it didn't have a single 12v rail. These are more reliable for the newer technology. I had the same problem when I built my new setup I used a new Zalman 750w PSU and thought it should be fine but I couldnt even get Windows installed so in the end I swap[ped itm out for a Corsair HX850 with a single 12v rail and never had another problem. The Zalman had four 20amp 12v rails  whereas the Corsair has a single 70amp.
