The MSI A850GF packaging is very much going with the Gold theme here today as it is decked in a black base with gold trim and a picture of the unit on the front. In addition to this, we see rows of advertising that includes things such as “Full Modular Cable Design”, “100% All Japanese 105C Capacitor” which are Japanese 105 c capacitors.
Among those things though, we also see that MSI is advertising this unit as adhering to the 80 Plus Gold standard of efficiency and has 80 plus gold certification. A quick check of the 80 Plus website, shows this unit is listed. Moving to the rear of the packaging of the A850GF, we find the power label (reproduced below) and the connector count (reproduced below). The rail distribution comes from the user manual, sort of (ok, not really). Lastly, the A850GF carries a 10-year warranty but, good luck finding that listed anywhere other than an animation on MSI’s website.
The A850GF is advertised as being a multi 12v rail power supply with a capacity up to 70.83A (or ~100% of the unit’s capacity) if necessary available to the 12v rails and promises lower energy consumption. The distribution of these rails is never that clearly defined. However, since this is the same power supply as the Enermax REVOLUTION DF 850W we can infer the same rail distribution as was present on that unit. The minor rails (5v and 3.3v) have a capacity of 22A each and the combined capacity of those two rails is 120W. Combined with these outputs, we find that this unit has 6 PCIe connectors, 8 SATA connectors, and 4 Molex connectors.
Once we open the MSI A850GF packaging, we are left looking at the unit, power cord, mounting screws, cables, and user manuals. The user manuals include the power label, connector counts, and a “Graphics Cards Power Connection” guide for all three members of this family. That, however, is it. With that out of the way, let’s move on to see what this unit looks like when we open it up!
