Antec HCP-750 Overview and Specifications

Today we take a look at the Antec HCP-750. Let's start with the delivery contents. Apart from the PSU itself the package includes a power cable, four screws to mount the device in the PC case, a short user guide, and the modular connectors in a separate bag. The HCP is protected from dust and dirt by a bag during shipping. The product features include 80 Plus Gold Certification, the 16-AWG connection cables (large wire cross-section), the 135mm PWM fan, and the gilded connectors. In addition Antec ofers a 5-year warranty, which is a common feature for a product like this.

The HCP-750 has four +12V outputs, each of which can be loaded with 40A according to the manufacturer. Almost the full power is provided here because of the DC-to-DC VRM. The +5V and +3.3V combined output is 150W. +5VSB can handle 3A (or 15W), and the label shows the various safety certifications. Antec products can be bought all over the world, so there are many country-specific requirements.

Antec uses a DC fan from ADDA with the model number ADN512UB-A9B. This one is controlled via PWM, so the duty cycle will be modulated. As a Sanyo Denki employee reported at Computex 2011, PWM is much better for the fan than voltage control. However, it should be mentioned that Antec has patented the use of PWM fans in PC power supplies, which complicates their use for other manufacturers. The fan needs 0.44A from the +12V output, and the nine fan blades pictured above are pretty well made.

    Because many companies use multiple PSU manufacturers, i.e. Antec, Corsair and others, I always recommend that consumers read objective PSU tests that show power output @ 50C, noise, ripple, etc. and that examine the internal components for quality. This Antec unit doesn't use the quality Japanese caps that better PSUs tend to use and this could be it's downfall for a couple dollars or less in production cost. Reply

    This article is rather bad in explaining the internals of an PSU. It assumes that every reader is an electrical/power electronics engineer! The technical stuff should be explained more and not simply analyzed without explaining to the (average) reader! Reply

    Why not have other PSUs listed in charts, like most reviews? That way we do not need to dig into old reviews to do direct comparisons to comparable products. Reply
