ASRock has announced the Pro Series full modular PSUs, available in 1000W, 850W, and 750W capacities. The units are fully compliant with ATX 3.1 and PCIe 5.1 standards and include high-quality 12V-2×6 power cables for powering the latest generation of graphics cards. 

The series carries dual 80 Plus Gold and Cybenetics Gold certifications, meaning it achieves 90% energy conversion efficiency at 50% load. Internally, the PSUs utilise an LLC + DC-DC topology and premium 105°C Japanese main capacitors. ASRock has also implemented a +5V Voltage Compensation feature, branded as 5V Boost, to maintain stable voltage under various load conditions.

Cooling is handled by a 135mm fluid-dynamic bearing fan with striped axial blades. According to ASRock, the 1000W and 850W models have earned Cybenetics Lambda A+ ratings, while the 750W variant is rated at Lambda A++. The fully modular design uses flexible black flat cables to assist with cable management. They also feature a dual-colour12V-2×6 connector system on the cables to help users confirm the installation is secure.

KitGuru says: Many newer PSUs are focusing on safety features for the 12V-2×6 connector. If this something that you would look for in a new PSU?

Gigabyte has announced the launch of its Gaming series power supply units, available in 750W, 850W, and 1000W capacities. The units feature T-Guard active thermal monitoring technology that monitors 12V-2×6 connector temperatures. The series carries Cybenetics ETA Platinum and Lambda A+ certifications and is fully compliant with ATX 3.1 and PCIe 5.1 standards.

The T-Guard technology utilises integrated thermistors within the 12V-2×6 connector to provide real-time thermal sensing. According to Gigabyte, the system triggers immediate alerts when it detects overheating caused by loose cables or abnormal loads. In the event of dangerous temperatures, the PSU reduces power specifically to the GPU while maintaining operation for other system components, allowing users to save data before a manual shutdown.

Gigabyte's new series has earned the Cybenetics ETA Platinum and 80 Plus Gold efficiency ratings. Cooling is managed by a 135mm FDB fluid dynamic bearing fan equipped with HybridCool technology, which allows the fan to stop during low-load scenarios for near-silent operation. This configuration has resulted in a Cybenetics Lambda A+ silence certification, translating to an average noise level below 20dB(A).

The Gaming series includes a dual-colour 12V-2×6 cable design intended to provide a visual confirmation of a secure connection through clear colour markings. The units are constructed using 100% Japanese capacitors and are available in both Black and Ice (white) editions. Gigabyte provides a 10-year warranty for the 750W, 850W, and 1000W models.

KitGuru says: It seems thermal monitoring sensors on the PSU side will become standard. After MSI and Asus, it's now Gigabyte that's doing the same to give users some extra peace of mind when they plug in an expensive RTX 50 series GPU.
