Not only is it sub-optimal to not note which 12V line goes to which output, I think their combination of CPU 12V feed and fixed PCIe cable on the same lines is also wrong. It would be better to bundle the ATX and EPS 12V cables on one line together with one or two modular PCIe outputs, and then have the fixed PCIe cables occupy one line each.

As for alternative PSUs I'd rather buy an Antec CP-850 which is cheaper, quieter, and optimised for my computer case.

Cheers
Olle

From the photo I can only see two chokes on the secondary, can you explain this, Gabe?

As far as I can remember the two transformers are connected together for the +12 V rail. There are two coils, one for the +12 V and +5 V and another for the +3.3 V. Unless you are seeing something I am not...

PS: Sorry for the delay in answering you.

Cheers,
Gabriel.

This is a ATNG like almost all Nexus PSU's, not a Sirfa/Sirtec/High Power.
