What this Thermaltake 1000W PSU has to offer
Ideal for high-end builds
The RTX 5090 is the best graphics card that money can buy, and it has a 575W rating from NVIDIA. What this means is that a 1000W PSU is more than enough to handle it, and you can add the best gaming processor alongside it without any issues. You’ll still be left with plenty of operational overhead for the rest of the components and overclocking. However, powering the build isn’t everything, as you also need a buffer that protects it, and this PSU comes with overcurrent, overvoltage, undervoltage, overpower, short circuit, and overtemperature protection.

ATX 3.1 and PCIe 5.1 compliant
If you’re putting together a new gaming PC, we would highly recommend going for an ATX 3.1 and PCIe 5.1 offering, as these aspects are like the ultimate safety upgrades. Modern GPUs are blazing fast, but when you have a lot of power, you also have a lot of energy draw and sudden bursts of power. When this happened with older PSUs, the entire system shut down, but with these technologies, the newer power supply units can handle these power excursions up to 200% of capacity with ease. One of the most appealing additions is the 12V-2×6 connector that can deliver up to 600W with a single cable, meaning it is more than enough to power an RTX 5090.
Fully modular
The fully modular nature of this power supply unit means that cable management will be easier, and you can simply use the necessary connections. This will also reduce the clutter, and you won’t have to shove unwanted cables into the PSU compartment, cramping the space and blocking the airflow. Also, the color-matched connectors make it easy to put everything in place, a great accessibility feature.
