Antec HCP-1200 Watt Power Supply Review

Cabling Arrangement




As you would expect from a 1200W power supply, there is quite a bit of cables and connectors available with the HCP-1200. The HCP-1200 features both an ATX 4+4 connector and an EPS12V connector should you need them. There are a total of eight 8-pin PCI-E connectors to power GPU's and while it is only certified for up to three video cards, it should have no trouble with four of them. Peripherals are powered by seven cables with a total of 12 SATA connectors and nine Molex connectors. Those still in need of a FDD connector can use the included adapter.




With a total of eight 12V rails, you would expect things to be complicated here, but it isn't. With the exception of the peripheral cables, each cable is on its own individual rail. The only bad thing about this is that it places all of the peripheral cables on a single 12V rail. This shouldn't be much of an issue as fans, hard drives and optical drives use little power, but in the event that you find yourself overloading 12V4, Antec has a solution for you. Their Advanced Hybrid Cable Management system allows you to connect the modular peripheral cables to the two modular PCI-E connectors, provided that you are not utilizing them for a third and/or fourth GPU. This lets you move some of the load off 12V4 and should keep it from being overloaded.


A Look Inside




Opening up the HCP-1200 reveals a dual PCB design where the primary is split between the two. This is the reason behind the single 80mm fan in the rear of the power supply. Since there is a PCB on both the top and the bottom, it would be impossible to utilize a larger fan on the bottom to cool things. This also explains the few modular cables since additional venting is required in the front to draw in fresh air through the use of the rear mounted fan.


Utilizing a dual PCB for power supplies is certainly nothing new, but Antec has a nice little twist on things here. While dual PCB designs typically feature the primary on one PCB and the secondary on the other PCB, the HCP-1200 has part of the primary on one PCB with the rest of the primary and all of the secondary on the other PCB. Here's part of the primary.




This side has a pair of Japanese made Rubycon caps.




The rest of the primary and all of the secondary for the HCP-1200 can be found on this PCB.




There are still a couple of smaller Rubycon capacitors for the primary.




The secondary side of things features a mix of more Rubycon capacitors with a few Nippon Chemi-Con caps thrown into the mix.




Cooling the HCP-1200 is an 80mm Sanyo Denki fan, model 9AH0812P4G131.
