Overview

The DeepCool PQ850M packaging is different from what we have seen from any other unit to date. The actual packaging comes as a plain brown box with a white sleeve over a portion of that box. On this sleeve, we find all of the printed information from the packaging. The front of the package is devoid of information save for the 80 Plus Gold seal. The rear of the packaging gives us most of the information we usually find. Indeed, there is a fan noise graph, efficiency graph, some advertising, the power label (reproduced below), and the connector count (reproduced below). It also mentions that this unit carries a 10-year warranty.

The PQ850M is advertised as being a single 12v rail power supply with a capacity up to 70A (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 just 3 PCIe connectors, 10 SATA connectors, and 3 Molex connectors. Given the low total 5v and 3.3v capacity, this makes for a strange arrangement. It is like this unit is meant to be used in systems with stacks of hard drives by the connector count but is then chocked by the power available to those drives.

Once we open the DeepCool PQ850M packaging we find the power supply, mounting screws, modular cables, the power cord, some Velcro straps, and the user manual. The user manual is very short and not informative in the least. Let’s move on to the unit itself now.
