The short version
The Core Reactor II VE 850W is XPG's fully modular ATX 3.1 power supply, rated Gold by 80 PLUS and Cybenetics and housed in a compact 140 mm chassis with a dedicated 12V-2x6 connector and a seven-year warranty. Tom's Hardware rated it a decent mainstream unit with good voltage regulation, but it grew loud and ran warm under heavy, hot loads. It suits typical gaming PCs rather than sustained workstation-style loads.
