GoKawiilBuilt by HKC on a platform that scales from 500W to 850W, the TR-KG750 clears 80 PLUS Gold at 115 VAC by fractions of a point and carries no Cybenetics listing. Regulation and ripple are acceptable rather than good; the sleeve-bearing fan never stops and turns loud under heat, and most of the silicon is anonymous. The $91 price and five-year warranty are the argument.

Thermalright is a CPU cooling company that happens to sell power supplies. Established in Taipei in 2001, it spent its first two decades building a reputation on air coolers - the Ultra-120 eXtreme and the HR series were enthusiast reference points long before the current wave of tower coolers - then drifted out of the conversation for years before the Peerless Assassin 120 dragged it back to the top of every budget build list in 2021. Its catalog has expanded aggressively since: case fans, all-in-one liquid coolers, thermal compounds, chassis, and, since 2022, power supplies. That last category deserves a different kind of scrutiny than the rest. Much like most brand names, Thermalright does not build power supplies; it commissions them, and a heatsink company's engineering credibility transfers to a PSU exactly as far as the OEM behind it allows. Every Thermalright power supply has to be judged on its platform rather than its badge.
The KG series occupies the value end of Thermalright's power supply range, and the TR-KG750 reviewed here is its 750W entry. How does it hold up against the best power supplies on the market? On paper, the specification is current, with ATX 3.1 and PCIe 5.1 compliance, a native 12V-2x6 connector, full modularity, 80 PLUS Gold certification at 115 VAC, a 120 mm fan inside a 140 mm-deep chassis, and a five-year warranty. The label on the PSU itself answers the platform question without much digging. The manufacturer of record is Somore Tech Co., Ltd., the production is credited to Jiushouyangguang Power Supply (Shenzhen), and the internal designation printed beside the 80 PLUS badge is HKCMAX-750 - this is an HKC platform, and the silkscreen on the main board dates the design to April 2023. There is no Cybenetics entry for the model at the time of writing, so the 80 PLUS report is the only third-party data available on it. At a retail price of $91, it undercuts essentially every name-brand 750W Gold unit on the US market, which is the whole of its pitch.

In the Box
The TR-KG750 arrives in a compact cardboard box wrapped in a black-to-bronze gradient sleeve, with a three-quarter render of the unit dominating the front and the wattage set in large gold type beside it. The badge strip along the bottom edge is short: 80 PLUS Gold, ATX 3.1, PCIe 5.1, and the model number.
