More a question come next-generation product suggestion than anything else. This PSU is triffic, but if I have one little criticism, it's the fact that both the four and eight pin ATX12v headers are hard-wired in.
This means that while I can get the remainder of the power wiring hyper neat thanks to the modular system, I'm left with the unused four-pin header ziptied to the main board supply bundle. Hardly a disaster, but I'm a perfectionist...
Was there a specific reason why both of these headers were hard-wired? From a neatness point of view, the ideal would have either been to make them modular as well, or possibly just to have the eight-pin header wired in, with the plug either "splittable" in the way the 24 pin is, or else with an eight to four pin adapter in the accessory bag. Indeed this latter approach might even have reduced the production costs a bit.
Again, not to denigrate a product that performs great as it is, more a suggestion for the future - if it can be done.
