Thermalright TR-SG1000 PSU ATX 3.1 1000W 80 Plus Gold, Full Modular

Thermalright TR-SG1000 is a 1000W ATX power supply from a higher class, aimed at more serious gaming and workstation configurations, including powerful modern GPUs. It combines 80+ Gold certification with 88% efficiency, so it maintains relatively low energy losses under high load. The power supply is fully modular, giving you freedom in cable management and better airflow in the case. Support for ATX 3.0/3.1 and PCIe Gen 5.0/5.1 makes it a relevant choice for the next generations of graphics cards.

What you get is a PSU ready to power a high-end CPU and GPU setup without gasping under peak loads. With a power of 1000W and a separate PCI-E 5.1 connector, you can comfortably plan for a modern graphics card without relying on adapters. The six PCI-Express 6+2 pin connectors allow for multi-GPU, additional cards, or more flexible cabling. 10 SATA and 5 Molex connectors are more than enough for many drives, fan controllers, and additional accessories in larger cases. The active PFC and 120mm fan help for more stable operation and more controlled temperatures under prolonged load.

• Power 1000W – sufficient for high-end gaming configurations and heavy workstations with powerful GPUs and many peripherals.
• 80+ Gold certification with 88% efficiency – less loss as heat and better energy efficiency under typical load.
• ATX 3.0/3.1 and PCIe Gen 5.0/5.1 support – ready for the new generation of graphics cards, including through a separate PCI-E 5.1 connector.
• Fully modular cabling – all cables are detachable, making assembly easier and maintaining a clean interior and better airflow.
• 6 x PCI-Express 6+2 pin and 10 x SATA – flexibility for multiple GPUs, SSD/HDD, and other devices in richly equipped systems.
• 5 x Molex connectors – convenience for older devices, fan hubs, and additional accessories.
• 120mm fan and active PFC – more stable power supply and temperature control during long gaming or rendering sessions.
• ATX format and input 100 – 240 VAC – standard compatibility with most PC cases and electrical networks worldwide.
• Black color and no RGB – clean look, suitable for systems without unnecessary lighting.

This power supply is suitable if you are building a powerful gaming PC or workstation with a high-end GPU and want a power reserve and current connectors for the next upgrade. It is also a good choice for more demanding systems with many drives and additional cards. It may not be the most sensible option if you are doing a strictly budget build or a compact system where 1000W and ATX format are excessive.

The combination of 1000W, 80+ Gold efficiency, and ATX 3.1 / PCIe Gen 5.1 support makes the Thermalright TR-SG1000 a stable foundation for a serious build with prospects for future upgrades. If you want to solve the power supply “at once” for several generations of hardware, this model is exactly that type of choice.
