ATX 3.1 is the latest power supply standard, designed to handle the high transient power spikes of modern CPUs and GPUs. It ensures better compatibility and stability with the newest hardware, including native support for PCIe 5.1 graphics cards.
80 PLUS Gold certification indicates a high level of energy efficiency, typically 87-90% efficiency at various load levels. This means less electricity is wasted as heat, leading to lower energy bills and a cooler system.
Yes, while it features a native PCIe 5.1 connector, it also comes with standard PCIe 6+2 pin connectors for compatibility with older graphics cards.
A fully modular design allows you to connect only the cables you need. This reduces clutter inside your PC, making cable management easier, improving airflow, and giving your build a cleaner aesthetic.
The Thermaltake Toughpower GT 850W comes with a 5-year manufacturer's warranty.
Please refer to the product's official specifications page for exact dimensions, as PSU sizes can vary slightly. Ensure it fits your PC case before purchasing.
Turn off and unplug your computer. Use a can of compressed air to gently blow dust away from the fan and heatsinks. Do this in a well-ventilated area. Avoid using vacuums directly on the PSU.
Verify all power cables are securely connected to both the PSU and the motherboard/components. Ensure the PSU switch on the back is in the 'ON' position. Check that the wall outlet is functional and the power cord is firmly plugged in.
Ensure the PSU is rated for your system's total power draw. Check that all necessary PCIe and CPU power cables are connected. Overheating can also cause shutdowns; ensure adequate case airflow and clean PSU vents.
Many modern PSUs feature a fanless mode at low loads. The fan should spin up under load. If the fan is not spinning even under heavy load and the unit is excessively hot, contact support.
Some minor coil whine can occur under specific load conditions, which is generally normal. If the noise is loud or persistent, it may indicate an issue. Contact customer support.
