Thermaltake Toughpower GF3 1000W (1000W/80+ Gold/ATX 3.0/High-End/Multi-Gpu Tier) Review

Thermaltake Toughpower GF3 1000W 1000W 80 Plus Gold fully modular power supply, ATX 3.0 certified, ATX form factor, native 12V-2x6/12VHPWR connector, 10-year warranty, CWT platform.

The Thermaltake Toughpower GF3 1000W is a 1000W step up from Thermaltake's original 850W GF3 launch unit, keeping the same native 12VHPWR/12V-2x6 connector so no adapter is needed for modern GPUs. Rated 1000W at 80 PLUS Gold (Cybenetics Gold efficiency / A noise), it's built on a CWT platform with a 140mm hydraulic bearing fan running a zero-RPM semi-passive mode at idle. Fully Modular cabling and a 160mm chassis depth make it a realistic fit for an RTX 4080/4090 or RTX 5080/5090-class high-end gaming build, and it's backed by a 10-year warranty.

Efficiency, Noise, and Build Quality

The Toughpower GF3 1000W carries an 80 PLUS Gold certification and a Cybenetics Gold efficiency / A noise rating, translating to consistently high real-world efficiency at typical 50% load and low fan noise thanks to its 140mm hydraulic bearing. It uses a CWT platform with Japanese-made capacitors throughout for long-term reliability under sustained load.

Connectors and Cabling

Connector layout is 1x 24-pin ATX, 2x EPS 4+4, 1x 12V-2x6 (600W), 4x PCIe 6+2-pin, 8x SATA, 4x Molex. With 1 native 12V-2x6 connector(s) rated to deliver up to 600W to a single GPU, there's no need for a 4x8-pin-to-12VHPWR adapter on current-generation flagship cards. Cabling is fully modular, using standard flat or ribbon cables, with a single +12V rail design that simplifies load balancing across connectors.

Comparison to Alternatives

Against the Corsair RM1000x (Corsair's ATX 3.1-certified 1000W Gold benchmark), the Thermaltake Toughpower GF3 1000W matches its wattage class but differs on connector generation and OEM platform, making the choice mostly about brand ecosystem, warranty length (10 years here), and whether native 12V-2x6 connectors matter for your GPU. Compared with the Seasonic Prime 1000 Platinum (Seasonic's 1000W Platinum flagship), the Toughpower GF3 1000W sits in the high-end/multi-GPU bracket at 1000W, so the decision usually comes down to matching wattage headroom to your actual GPU/CPU combo rather than one being categorically better.

Expert Review

Reviewed by Burooj Alam. Rated by us, not by users.

Expert rating8.3 / 10

A solid 1000W Gold-rated ATX unit for an RTX 4080/4090 or RTX 5080/5090-class high-end gaming build, held back only by the usual mid-tier compromises on cabling and OEM sourcing.

Best for

  • Builders targeting an RTX 4080/4090 or RTX 5080/5090-class high-end gaming build
  • Anyone who wants fully modular cabling with native 12V-2x6 support
  • Systems where a 10-year warranty and Gold-tier efficiency matter

Not for

  • Builds needing more than 1000W of continuous headroom
  • Buyers who need the smallest possible SFX/SFX-L footprint
  • Cost-sensitive builds better served by a lower-tier 80+ Bronze unit
