Know before you buy
Yes, it is fully compatible with modern hardware. It features a native 12V-2x6 connector, which is the updated standard for the latest PCIe 5.1 graphics cards, ensuring a secure and direct connection without needing adapters.
Being fully modular means every cable can be detached from the power supply unit. This allows you to use only the cables you actually need, significantly reducing clutter in your case and improving internal airflow.
The unit uses a 135mm Fluid Dynamic Bearing (FDB) fan paired with an iCOOL semi-passive mode. This means the fan can remain completely still during low-load tasks and operates very quietly even when the system is under stress.
The unit is built with 100% high-quality 105°C Japanese capacitors, which are known for their reliability and longevity. ASRock backs this build quality with a comprehensive 10-year warranty.
While the unit is 80 PLUS Gold certified, its Cybenetics PLATINUM rating indicates it has passed even more rigorous testing for efficiency and noise levels. It confirms the unit operates at a very high level of energy efficiency and maintains a quiet acoustic profile.
Yes, this is a standard ATX form factor power supply. It is designed to fit into the vast majority of mid-tower and full-tower PC cases on the market.
