Thermaltake Toughpower GF3 850W 80 PLUS Gold Modular ATX Power Supply

The Thermaltake PS-TPD-0850FNFAGU-4 is an 850 watt ATX power supply that brings reliable, efficient power to gaming towers, creative workstations, and any build that expects steady performance under load. Rated 80 PLUS Gold, it can reach up to 90 percent efficiency, which means less wasted energy, lower heat, and reduced strain on your cooling system.

Every cable is fully modular, so you only connect the leads your components actually need. The result is a cleaner interior and smoother airflow, making it easier to keep temperatures in check and to showcase your build through a side window.

A 135 mm fan that uses a fluid dynamic bearing handles cooling. When the system is idling or under lighter workloads, Smart Zero Fan technology holds the blades still, eliminating fan noise entirely. As demand rises, the fan ramps up smoothly to keep critical components within their safe temperature range.

This unit is built for today’s and tomorrow’s hardware. Intel ATX 3.0 compliance and a 16-pin power connector let you feed the latest PCIe 5.0 graphics cards without relying on adapters. Twelve SATA connectors, four traditional PCIe connectors, and a strong single +12 V rail give you plenty of headroom for storage arrays, high-speed NVMe enclosures, or multiple GPUs in older formats.

Long-life capacitors, an MTBF of 100 000 hours, and a full suite of protections against overcurrent, overvoltage, undervoltage, and short circuits help ensure that your system stays safe during marathon gaming sessions or overnight rendering jobs.
