We would like to thank XPG for supplying the review sample.

I already evaluated the XPG Core Reactor with 750 W, so it is nigh time to take a look at the strongest member of the line. These units are based on a Channel Well Technology (CWT) platform and are not only 80 PLUS Gold certified, but also have Cybenetics efficiency and noise badges. To be more specific, the Core Reactor 850 W meets their ETA-A and LAMBDA-A- rating requirements, which means it is efficient and very quiet overall.

The Core Reactor 850 is fully modular, and XPG mentions that only high-quality parts are used inside, including Japanese capacitors and a fluid dynamic bearing fan. Moreover, it has enough connectors to power a truly high-end system, although I would advice against fully utilizing all available EPS and both PCIe cables featuring two PCIe connectors each at the same time.

A definite asset is its extremely shallow depth of only 140 mm. This is PSU downsizing at its best since you have 850 W of power in a compact enclosure that will easily fit into any ATX case. This will also make installation easier as it helps make up for the stiff modular cables.
