AX1200i question about PCIe rails

[broken pixel]

I am wondering why the AX1200i PSU only supports 3 GPUs? I would expect this top of the line PSU to support more than 3 GPUs:(: You guys skimped out on the rails man. Or am I missing something?

 

I also have an Evga NEX750G and it is able to power 4 GPUs because of the split single rails x 4 ports.

My graphics cards came with molex adaptors

Um...It's a single rail PSU.

 

You can power another GPU using molex adapters if you would like.

I also have an Evga NEX750G and it is able to power 4 GPUs because of the split single rails x 4 ports.

It just has four cable connections. Most GPU's will use two of those for each card. Even if each cable has two connectors on it, it still wouldn't be powerful enough to power four modern GPU's. Maybe 4 8800gt's , but not something like four 660's,680's ect.
