ASUS' ROG THOR PSU range launches a new 1600W model that features Gallium Nitride MOSFETS
ASUS's latest ROG THOR series power supply is a 1600W monster, promising to be the "quietest 1600W power supply" by offering users high levels of power efficiency, improved heatsinks when compared to competing PSUs, and a custom PWM controlled 135mm Axial-tech fan.
One uncommon addition to ASUS' new 1600W THOR power supply is its Gallium Nitride MOSFETS, which promise users lower switching losses and higher efficiency levels than traditional silicon transistors. The first PSU that we looked at with Gallium Nitride MOSFETs was Corsair's 1600W AX1600i PSU (review here), which launched in 2018. So far, few power supply manufacturers have adopted Gallium Nitride MOSFETs, but as higher wattage PSUs become more common, we expect this addition to become increasingly popular.
The ROG THOR 1600W power supply boasts an 80+ Titanium efficiency rating, and a Lambda A++ low noise certification from Cybenetics. With these ratings, ROG's THOR 1600W power supply promises to be quiet and incredibly efficient.
Another add-on for ROG's new THOR power supply is its OLED screen and RGB LED lighting, which allows the unit to display the amount of power the PSU is using and be colour matched with other components within your system.
Why do we need a 1600W power supply?
To give you a simple answer, we need higher wattage power supplies because future high-end graphics cards are coming to be incredibly power-hungry. Nvidia's RTX 3090 Ti Founders Edition already consumes 450 watts of power, and the industry's new PCIe 5.0 power standard can allow power supplies to deliver up to 600 watts of power over a single cable. That means that GPUs with two 16-pin PCIe 5.0 power cables could theoretically consume up to 1200 watts of power. That's insane.
If you are planning to run a system with an overclocked next-generation graphics card and a powerful processor, you will need a power supply that can meet your power requirements. Once you add in some watts for your system's storage, lighting, and other add-ons, you will need a beefy power supply. That's why ASUS is working on a 1600W THOR series PSU.
ASUS has confirmed that their new THOR series power supply will support PCIe 5.0 power, and that the cables that are supplied with the PSU will be braided. PCIe 5.0 power cables are expected to be common on next-generation RTX graphics cards from Nvidia, though these GPUs are expected to ship with 16-pin PCIe 5.0 power cable adaptors, so that these GPUs can be used with older power supply units. ASUS has confirmed that their 1600W power supply will ship with a single PCIe 5.0 power cable.
