Thermalright TR-SG-750 ATX 3.1 750W Plus Gold PSU

Thermalright TR-SG-750 is a 750W ATX 3.1 power supply with 80+ Gold certification, aimed at mid-range to more serious gaming and workstation builds. It provides enough power for a strong CPU and modern GPU, including a PCI-E Gen5 card via the 12VHPWR connector. With efficiency up to 87% and active PFC, the power supply is designed to maintain stable voltages and lower losses. The full modular design helps you organize your cables neatly and remove all unnecessary clutter from the case.

What you get

With a power of 750W, you have enough headroom for most combinations of a strong multi-core CPU and a modern graphics card, without constantly hitting the limit. The ATX 3.0/3.1 compatibility and the PCI-E Gen5 12VHPWR connector mean that you are covered for current and future GPUs from the latest generations, without the need for adapters. The full modular implementation gives you the freedom to connect only the necessary cables – better airflow, easier cable management, and a cleaner build. The 120 mm intelligent Start-Stop fan can stop at lower loads, reducing noise during idle and light tasks. The DC-DC LLC Half-Bridge structure and Japanese capacitors rated for 105 °C are focused on stability and long life under prolonged load.

• Power 750W – sufficient for a strong gaming or workstation build with a modern CPU and one powerful graphics card, without entering risky limits.
• 80+ Gold certification and efficiency 87% – less loss as heat and more stable operation under typical load.
• ATX 3.0/3.1 and PCI-E Gen5 12VHPWR connector – ready for the latest GPU standards without additional adapters.
• Full modular design – all cables are detachable, making assembly easier, improving airflow, and enhancing the aesthetics of the build.
• Rich set of connectors: 20+4 Pin ATX, 4+4 Pin ATX/EPS x2, PCI-Express 6+2 pin x4, Molex x3 and SATA x8 – covering both a powerful system and plenty of storage/accessories.
• 120 mm intelligent Start-Stop fan – can operate only when needed, for a quieter system under light loads.
• DC-DC LLC Half-Bridge structure and Japanese capacitors 105 °C – aimed at stable lines 3.3/5/±12 V and long-lasting reliability.

Who it is suitable for

TR-SG-750 is a good choice if you are building a mid-range or high-end gaming PC with one graphics card, and want ATX 3.1 and PCIe Gen5 12VHPWR to be secured. It is also suitable for productivity machines with many drives and peripherals, thanks to the rich connectors. If you are aiming for an extreme enthusiast build with multiple GPUs or overconsumption, a higher wattage would be more appropriate.

The combination of 750W, 80+ Gold efficiency, ATX 3.1 with Gen5 12VHPWR, and full modular design makes this power supply a very balanced option for a modern gaming or workstation build. The preparation for new GPU standards is especially valuable, without paying extra for kilowatt PSUs.
