GoKawiilThermalright'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.
GoKawiil's interpretation of the reporting above, not reported fact.
Thermalright built its name on CPU coolers, not power delivery, and like most brands in this segment it simply rebadges an OEM design rather than engineering its own—so the badge tells buyers little about actual quality. At $91 with a five-year warranty, the TR-KG750 is being sold on price and support rather than performance, which matters for budget builders who assume Gold certification and modern connector standards guarantee solid engineering underneath.
- The TR-KG750 is manufactured by HKC, not Thermalright itself, on a platform scaling from 500W to 850W.
- It barely meets 80 PLUS Gold efficiency and has no Cybenetics noise or performance rating.
- Its main selling points are the $91 price and a five-year warranty rather than component quality or fan noise.
Corsair RM750e 750W ATX 3.1 PSU — If this review leaves you wanting a 750W unit with a clearer pedigree than an anonymous budget build, the Corsair RM750e is a well-known alternative in the same wattage class. It's fully modular with a native 12V-2x6 connector for current GPUs, and Corsair's fan curve keeps it quiet at low loads instead of spinning constantly. A solid pick for a mid-range gaming rig.
