Antec High Current Pro 1200W Modular Power Supply Review

The High Current Pro comes in three different versions: 750W, 850W and 1200W. This 1200W unit is rather different from the others in terms of layout as you will see later in the review. Every unit in the High Current Pro series holds 80+ Gold certificates and feature a semi-modular design. Looking at the power table, we can see that the unit outputs a total of 99A through its 12V rails which means it can provide a total of 1188W exclusively on the all important 12V rails. Spot anything odd about those 12V power rails? I did, and it took a while to sink in! It has 8 12V rails, as in eight! This is the part where I would normally embark on a rant about how much harder multiple power rails are to set up due to having to balance them, however if you are investing over £200 on a premium 1200W PSU I would hope that you would know how to do this properly. And at such high power, having multiple rails will provide a lot more stability than forcing it all through a few. You don’t want to know how many hours I spent configuring this unit to provide the optimum amount of power to my load tester which has only 2 rails!

The unit comes with a nice selection of modular cables, one feature that I really liked was daisy chained PCI-e power connectors. Anyone running a 1200W PSU will be running cards that require more than one PCI-e power connector, so why run 2 cables there when you can run a single cable with two connectors? The PSU includes 8x 6+2-pin power connectors allowing for quad-SLI or Crossfire configurations. Antec cleverly include two 8-Pin EPS connectors- there are many high-end motherboards out there that require more than one EPS connector in addition to multi-CPU boards that someone buying a 1200W PSU may be interested in. The cables are all heavy 16 AWG wires that reduce impedance thus reducing energy wasted as heat which aids efficiency.
