Thermalright TR-KG750 is a 750W ATX power supply with 80+ Gold certification and a fully modular design, aimed at mid-range to more serious gaming and workstation configurations. You get ATX 3.1 compatibility and support for PCIe Gen 5.0/5.1, preparing it for modern GPU cards with the new connector. Efficiency up to 90% helps reduce consumption and heat output, while a 120 mm fan takes care of cooling. The black design is simple and easily fits into most cases without unnecessary lights.

What you get
With a power of 750W and active PFC, this power supply comfortably covers a typical gaming system with a more serious GPU and numerous devices. ATX 3.0/3.1 and PCIe Gen 5.0/5.1 support means you have a modern PCI-E 5.1 connector for next-generation graphics cards, without relying on adapters. The modular design allows you to connect only the necessary cables, improving airflow and making cable management significantly easier. The 80+ Gold certification and efficiency up to 90% reduce losses and heat under high load, which is a plus for both the electricity bill and overall stability. The additional LLC Resonance + DC-DC design is aimed at more stable voltages on the 3.3/5/±12 V lines, especially important under combined CPU and GPU load.

• Power 750W – sufficient for a solid gaming or workstation computer with a powerful GPU and several additional devices.
• 80+ Gold certification and efficiency up to 90% – less energy loss, lower temperatures, and quieter operation under typical load.
• ATX 3.0/3.1 with PCIe Gen 5.0/5.1 support – ready for modern graphics cards via the special PCI-E 5.1 connector, without the need for adapters.
• Full modular design – you connect only the necessary cables and keep the interior of the case clean with better airflow.
• Rich set of connectors – 20+4 Pin ATX x1, 4+4 Pin ATX/EPS x2, PCI-Express 6+2 pin x2, PCI-E 5.1 x1, SATA x6 and Molex x3 cover most combinations of GPU, SSD, HDD, and peripherals.
• 120 mm fan – provides cooling for the power supply components at 100–240 VAC input, suitable for stable 24/7 operation.
• LLC Resonance + DC-DC Circuit Design – aimed at more stable DC 3.3/5/±12 V lines under varying system load.

Who it is suitable for
This power supply is a good choice for gaming and enthusiast configurations aiming for a serious GPU and wanting ATX 3.1 and PCIe Gen 5.0/5.1 compatibility. It is also suitable for workstations with multiple drives and a need for stable, efficient power. If you are pursuing extreme overclocking on a multi-core CPU plus a top high-end GPU and numerous additional devices, you might consider a higher wattage.

The combination of 750W, 80+ Gold efficiency, full modular design, and support for PCIe Gen 5.0/5.1 makes the Thermalright TR-KG750 a balanced and current solution for modern gaming and workstation PC builds.
