Thermalright's $91 KG750 power supply is an HKC-built unit with barely-there Gold efficiency
Tom's Hardware tested the Thermalright TR-KG750, a 750W ATX 3.1 power supply built for Thermalright by OEM manufacturer HKC. The unit squeaks past 80 PLUS Gold certification at 115 VAC, lacks any Cybenetics efficiency or noise rating, uses mostly unbranded internal components, and pairs mediocre voltage regulation and ripple suppression with a sleeve-bearing fan that runs constantly and gets loud under load.
