The short version
The TUF Gaming 850W Gold is ASUS's ATX 3.0 power supply with a native 16-pin cable on both ends, three 8-pin PCIe connectors and a 150 mm casing. Tom's Hardware measured excellent voltage regulation and quiet running under load, and ASUS backs it with a ten-year warranty, but the reviewer criticized a low connector count and high internal temperatures. It suits mainstream gaming builds that value warranty length over connector count.
