High Power Astro GD 750 W Review

A Look Inside & Component Analysis »


The window at the front-center provides a view to the specially designed fan grill of the unit. On the left are the model description and three badges for its Gold efficiency, digitally controlled VRMs, and, in the bottom-right corner, the power meter the PSU is equipped with.

One of the two sides informs us that this is a PSU. Well, that is good to know! The other side only hosts the model description.

The top has High Power's website address.

The most important stuff is as per usual located on the back of the box. A, in this case, specifications table and the power input/output specs. There is also a mention of the digitally controlled VRMs the PSU utilizes for the generation of the minor rails; that is, according to High Power. Here we should add that most modern PSUs feature DC-DC converters in their secondary side, but only a few of them utilize digital control circuits to regulate these. Going digital in PSUs is still an expensive sport, which has most manufacturers prefer analog ICs for control over the APFC and the primary and secondary side.

This side also has a scheme depicting the fan's operation throughout the entire load range. The PSU works in fan-less mode at a load of up to around 25%. Only afterward does the fan engage. High Power's embedded power meter is called eagle eye.


Inside the box is the PSU surrounded by packing foam, but the window exposes its top, leaving it unprotected.

The bundle includes the essential modular cables, a set of fixing bolts, a case badge, an AC power cord, a user's manual, and, thankfully, a pouch for the modular cables. The latter strangely enough had Xigmatek's logo on it!


The AGD-750's golden accents around the fan grille give it a flamboyant look. The white-colored fan also plays its part, with the "H" holes of its grill. The finish is generally nice and the side decals match the overall design of the unit. The front has the embedded power meter that uses a tri-colored LED indicator of three zones to depict power output as a percentage. This is an interesting feature, but the location of the power meter is inconvenient since you will have to get behind the PC chassis to take a look. It should ideally be an external one, but such would increase the cost because it would require an appropriate interface, and the USB port interface on PSUs is already patented by Gigabyte.

We liked the looks of the unit. We are, however, pretty sure that many of you will not share our opinion. As a side note, there are quite many native cables for a modular PSU. They could omit the second native EPS connector as most users won't utilize it, making it modular instead.

The native cables are fully sleeved back into the PSU's housing and are not stealth. The modular cables are thankfully flat (ribboned) and stealth!
