The Antec GSK 850W PCIe 5.1 Gen5 80 PLUS Gold Fully Modular Power Supply combines cutting-edge technology with premium build quality, making it a top-tier choice for gamers and professionals. With ATX 3.1 and PCIe 5.1 compatibility, this PSU ensures seamless performance for modern systems, including support for NVIDIA® GeForce RTX™ 40 Series GPUs via its 12VHPWR 12V-2×6 cable. Featuring 80 PLUS Gold certification, it delivers up to 90% energy efficiency, reducing power waste and keeping your system cooler and quieter during operation. The fully modular design allows for precise cable management, eliminating clutter and improving airflow.
At the heart of the GSK 850W is its PhaseWave™ Design, a server-class LLC topology with synchronous rectification and DC-DC conversion that guarantees unparalleled stability and efficient power delivery. The power supply is equipped with high-quality Japanese capacitors, ensuring tight voltage regulation and minimal ripple for enhanced system performance and longevity. Safety is paramount, and the CircuitShield™ suite of protections—including OCP, OVP, UVP, SCP, OPP, OTP, SIP, and NLO—safeguards your components in any operating environment.
Cooling is handled by a 120mm fluid-dynamic bearing (FDB) silent fan, renowned for its durability and quiet operation. The Zero RPM Manager enhances thermal efficiency by activating the fan only when needed, offering near-silent operation during low loads. Compact and versatile, the GSK 850W is designed to fit a wide range of cases while providing exceptional reliability, efficiency, and ease of use. With its advanced features and 5-year warranty, it’s an ideal solution for powering your next high-performance PC build.
Purchased online, Price was well below cost of components online. Free Courier delivery. Packaging excellent ( double boxed ). PC was clean, all documentation & power cable included. Specs exactly as advertised. Very noticeable improvement from my 16gb 2.4khz laptop.
Side note for buyers ( I was already aware of this ) - this CPU has on-board graphics, so it will use some of the system RAM for the graphics. Default on mine is around 8Gb for the graphics, leaving me around 23Gb RAM for the CPU. Adding a graphics card would free up that ram for CPU use. Overall, very impressed with the PC and would order the same brand again from Matrix without hesitation.
Purchased online at the most affordable price and picked up my item in store to skip delivery delays and fees. Great service.

Great little motherboard and came with a back plate
Great little motherboard and came with a back plate. Booted up first try with my core i5 CPU and 6 GB DDR3 RAM and 2 SATA drives. Really great budget option for legacy hardware. Well done Arktek!
