Antec High Current Pro Platinum 1000W Power Supply Review

Here are a few pictures showing the layout and components inside the new High Current Pro 1000W Platinum power supply. The HCP-1000 Platinum PSU features a server-class full-bridge LLC topology with synchronous rectification and uses DC-to-DC converter technology. The LLC resonant design allows for zero voltage switching, which dramatically lowers switching transistor losses to boost efficiency. Once again, Antec has teamed up with Delta Electronics as their OEM to co-develop the High Current Pro Platinum PSU.

Once inside, it becomes quickly apparent that this really is a “new platform”. The most obvious change is what Antec refers to as a “wireless PCB design”. The normal maze of output wiring is absent and most of the electrical connections are made through the PCBs instead of external interconnects. Even the main transformer uses sheet copper instead of the more traditional wire windings. Direct copper wire connections to the synchronous rectifiers also help reduce losses and achieve 80 Plus Platinum efficiencies.

The two primary capacitors are made by Nippon Chemi-Con and are rated for 470uF, 450V, and 105°C. The secondary features both electrolytic and solid polymer caps also made by Nippon Chemi-Con; very nice. Notice that both the +3.3V and +5V DC-to-DC converter boards have been moved off the main PCB and instead are mounted directly to the front modular DC connector board, eliminating more wiring and reducing current losses and boosting efficiency. This is functionally what Seasonic did with their X-Connect series of PSUs.

The overall layout, build quality and component selection appears to be excellent.

What about the HCP-1200? Have you or can you review that one? thanks

Usually if we do a review of one in a family, that is all we'll do. The 1200 watt should be pretty dang close here.

If you use site search, you can find that HCP-1200 was reviewed a while ago.

True, but it was the previous generation from 2011:

HCP-1200 trumps the HCP-1000 in build quality, performance and in peak power capacity.

It's the second best PSU out in the market coming after the AX1200i.

The build quality of the Hcp 1000 is second to zip sonny, Ax1200i your kidding right, tosser.

Is there a HCP-1200 Platinum?

January 17, 2013 | 11:02 AM - Posted by WillRock (not verified)

No, however Delta has built the HCP-1200 in a Platinum offering for servers, which (unfortunately) failed to clear Platinum and stayed at Gold efficiency. It's not out yet for servers, let alone in a pretty, tidied up shape for builders.
