Thermaltake PS-STP-1000FNFAPU-1 1000W Platinum ATX 3.1 PSU

The Thermaltake Toughpower SFX 1000W is engineered for builders who refuse to compromise on power delivery despite working within the space constraints of compact SFX and mini-ITX enclosures. At just 125mm x 63.5mm x 103.8mm, it packs a full kilowatt of output into a footprint that fits where standard ATX supplies cannot, while the included SFX-to-ATX adapter bracket extends its compatibility to full-size cases. The unit meets ATX 3.1 standards and PCIe Gen 5.1 specifications, featuring a native 12V-2x6 (12+4 pin) connector that delivers clean power to the latest graphics cards without relying on adapters that can introduce voltage drop or reliability concerns.

Under the hood, the Toughpower SFX 1000W achieves 80 PLUS Platinum certification — meaning efficiency exceeds 92% at 50% load — which translates directly to lower heat output and reduced electricity consumption. Voltage regulation is held to less than ±2%, and ripple noise stays under 30mV, specifications that protect sensitive modern hardware from the power quality issues that can cause instability or reduced component lifespan. A 90mm fluid dynamic bearing fan provides cooling with minimal friction and wear, and the fully modular cable design uses low-profile connectors to ease routing in cramped SFX builds. With a hold-up time of 17ms or greater, the unit also handles brief power interruptions gracefully, making it a strong choice for high-end small form factor workstations and gaming systems alike.
