FunkyKit reviewed the Thermaltake Toughpower SFX 1000W Gold TT Premium Edition and highlighted its impressive performance in a compact SFX-L form factor. Designed for high-end small form factor builds, this unit is 80 Plus Gold certified and meets Intel ATX 3.0 standards. It delivers 1000 watts of continuous power through a single 12V rail rated at 83.3A. The PSU includes a native 16-pin 12VHPWR connector for next-gen GPUs, along with dual EPS CPU connectors and fully modular, low-profile flat cables. Built with premium Japanese 105°C capacitors and industrial-grade protections, it also comes with a generous 10-year warranty, reinforcing its status as a premium power supply for compact systems.
" ... I have to say the Thermaltake Toughpower SFX 1000W Gold TT Premium Edition PSU is genuinely impressive. It’s rare to find a power supply this compact that delivers such consistent voltage stability and handles demanding components without a problem. From its precise regulation under load to the quiet cooling and top-tier build quality, it feels like Thermaltake packed all the right features into a small form factor without cutting corners. For anyone building a high-performance SFF rig and wanting peace of mind with future upgrades, this PSU ticks all the boxes. "
During testing, the Toughpower SFX 1000W demonstrated excellent voltage stability, low ripple, and efficient thermal management. The 120 mm FDB fan remained completely off under low to moderate loads thanks to the Smart Zero Fan mode, resulting in silent operation in typical daily use. Even under heavier loads, fan noise stayed low and performance remained consistent. Efficiency hovered around 90 percent or better across most power levels. FunkyKit praised its build quality, strong cable design, and future-ready connectivity, recommending it as an outstanding choice for users building powerful mini-ITX or SFF PCs that demand quiet operation and dependable power delivery.
