Thermaltake Toughpower GF3 1350W Power Supply - PCIe 5.0 Ready

Our review of the Thermaltake Toughpower GF3 1350W finds it aimed at builders who need a stable, high-capacity PSU for top-tier gaming rigs and multi-GPU or workstation setups. The single biggest reason to consider it is its native 12+4pin 12VHPWR connector that can deliver up to 600W to a single PCIe 5.0 graphics card while meeting Intel PSDG ATX 3.0 requirements, making it future-proof for current RTX 40 series cards and other next-gen GPUs. It is a solid choice when silence, high-quality components, and long-term warranty peace of mind matter.

Key Features

• ATX 3.0 compatibility: Built to the Intel PSDG ATX 3.0 specification so it supports new power delivery requirements for modern systems.
• PCIe Gen 5.0 ready: The native 12+4pin 12VHPWR connector supplies up to 600W to compatible graphics cards for reliable GPU power delivery.
• High-quality capacitors: Uses 100% Japanese 105C/221F capacitors to improve longevity and voltage stability under sustained loads.
• Fully modular cables: Low-profile flat cables simplify installation and cable management in tight cases and custom builds.
• Ultra quiet cooling: The 14cm hydraulic bearing fan and smart zero fan control keep noise low and reduce coil whine complaints for many users.
• Long warranty: A 10 year warranty provides extended coverage, reflecting confidence in build quality and durability.

Who It's For

The Toughpower GF3 1350W is best for enthusiasts building high-end gaming PCs, content creators running powerful GPUs, and anyone who plans to use PCIe 5.0 graphics that require the 12+4pin 12VHPWR connector. It suits multi-GPU or heavy workstation builds that need sustained, high wattage and clean rails.

Those who should look elsewhere include buyers who need a lower wattage, budget-focused PSU or compact SFX form-factor models, since this unit is a full-size ATX supply and is optimized for high-output configurations rather than entry-level systems.
