Thanks to some bold red tag logos and a heavily diffused matte black finish, the Antec HCG-620M is more attractive than your average black box PSU. The red and black color scheme is present on every face of the unit except for the top, where a tasteful silver Antec badge lies surrounded by a wire fan grille. More branding can be found in the lower front corners of the enclosure in the form of raised Antec logos. The large openings in the fan grille and hexagonal rear venting show off the unit's internals and a surprising amount of unused space. All of the HCG-620M's cables, or "Stealth Wires" as Antec prefers to call them, feature black sleeving to blend in with their surroundings. The 20+4-pin and ATX12V/EPS12V power cables protrude from a grommeted opening, while the included PCI-E, SATA, and accessories cables have their respective homes inside the HCG-620M's modular sockets. What makes Antec's modular design special is how they have combined 5-pin and 10-pin cable compatibility into a set of four 10-pin sockets for maximum flexibility. Everything on the unit, from the enclosure panels to the fan grille, cable sockets, and cable sleeves all portray an image of quality that is matched by the HCG-620M's reliable performance under the hood.
We are presently in the process of raising funds to acquire power supply testing equipment. As a courtesy to our readers, we do not attempt to present inaccurate data obtained from using a PC to load the power supply. We find such testing to be highly variable and inconsistent with our standards for delivering informative and genuinely useful information to our readers. Our current capabilites limit us to draw high level conclusions about the performance of the power supplies that come across our test benches, as we do not posess the resources needed to perform full stability, power signal quality, and regulation testing. With that said, let's take a closer look at what the internals of the HCG-620M have to offer.
