ASUS ROG THOR 850W Power Supply Review


The ASUS ROG THOR 850W packaging has a premium product “feel” to it. The front of the package starts the Republic of Gamers branding and includes a picture of the power supply and a row of seals including one for “ASUS AURA SYNC”, a 10-year warranty, and an 80 Plus Platinum seal. This is a bit of a pattern as the back of the package has advertising about features including the inclusion of “OLED POWER DISPLAY”, “ASUS AURAU SYNC”, “ROG HEATSINK”, “80 PLUS PLATINUM CERTIFICATION”, “WING-BLADE FAN”, and “SLEEVE CABLES”. None of this is revolutionary, but many of these items are unique design touches to this unit which will cost more and give this unit some definition. Also, none of these items are going to be amazing contributors to the unit’s performance which is important to keep in mind. On the side of the packaging is the power label (reproduced below).

The ROG THOR 850W is advertised as being a single 12v rail power supply with a capacity up to 71A (or ~100% of the unit’s capacity) if necessary available to the 12v rail. 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, 10 SATA connectors, and 5 Molex connectors.

Once we open the ASUS ROG THOR 850W packaging we find the power supply, mounting screws, modular cables in a bag, the power cord, the user manual, and some accessories like zip-ties/case badges/cable combs. The user manual covers this model as well as the 1200W model and it is long at 116 pages long in 19 languages. That length, however, does not mean that it is terribly informative as we find just a contents list, power tables, connector counts, etc. The manual is not one of the best to ever be printed but ASUS is fairly new to producing power supplies. Let’s move on to the unit itself now.
