Overview

The FOCUS GM-650 packaging is about what we would expect to see given that this is a refresh of the FOCUS line of power supplies and the previous examples follow this same layout. The front of the package is bare of information save for the advertising about the 7-year warranty, and the 80 Plus Gold seal. When we check the 80 Plus website we find that this unit is listed and, as such, we will see how it does in this regard later. The rear of the packaging has a lot more in the way of advertising as we find advertisements for the unit size, FDB fan, fan controller, voltage regulation, Japanese capacitors, gold plated connectors, etc. This is in addition to the efficiency graph found here as well. The side of the package has the power label (reproduced below) and the connector count (reproduced below).

The FOCUS GM-650 is advertised as being a single 12v rail power supply with a capacity up to 54A (or ~99% of the unit’s capacity) if necessary. The minor rails (5v and 3.3v) have a capacity of 20A each and the combined capacity of those two rails is 100W. Combined with these outputs, we find that this unit has 4 PCIe connectors, 6 SATA connectors, and 3 Molex connectors.

Once we open the FOCUS GM-650 packaging we find the power supply, mounting screws, modular cables, the power cord, Velcro straps, zip ties, power supply tester, and the user manual. The user manual comes in two parts and covers some basic installation, warranty, and troubleshooting items. Let’s move on to the unit itself now.

  1. As always, an excellent review Paul!

    Nice little PSU. I don’t mind the "semi"-modular design of it either. You’re going to be hooking up the ATX and ATX Power cables anyways, no real reason they have to be modular.

  2. Nice review. I’m running a 550W Seasonic Focus PSU in my wife’s PC here with no issues, and decided to go with the 1000W Seasonic in my main PC which has also been rock solid. Always liked their warranties.

    Does make installation / cable management a bit easier when you have a bit more flexibility in routing by virtue of having both ends free, but yeah, your going to use them no matter what.
