There are quite a few different cables here and it increased the flexibility of the power supply. I'm still not a fan of how they treated the PCI-E and EPS12V cables. Forcing them to share the same spot on the power supply limits the power supply a little bit in that you can't power four video cards and supply dual EPS12V cables to the motherboard.
I'm also not sure why the FDD connector isn't just an adapter. I've not seen one used in ages and I'm sure very few people using a power supply of this cable have any use for it. They are much more likely to need that second EPS12V connector along with their four video cards first.
Rail distribution is as simple as it gets with a single 12V rail. There is no need to worry about load balancing here.
A Look Inside
There isn't much passive cooling going on here as there are only one long and one short heat sinks present. Thankfully the design keeps clutter to a minimum and allows the air to penetrate deep to the PCB and move the hot air out of the unit.
Two Nippon Chemi-Con capacitors reside on the primary side of the power supply.
The secondary side is filled with more Chemi-con caps.
FSP uses the Power Logic PLA13525S12M 135mm fan to provide all of the active cooling for the Aurum Pro 1000W.
