Power Supply 1stPlayer ACK HA-850BA2, PSU ATX 3.1, 850W 80 Plus Gold, Full Modular

1stPlayer ACK HA-850BA2 is an 850W ATX power supply with 80+ Gold and ATX 3.1 / PCIe Gen 5.0/5.1 support – right in the sweet spot for serious gaming or high-end configuration. 850W gives you enough headroom for a powerful GPU and many peripherals, without going into absurd wattages. The full modular design makes cable management much easier and cleaner, and the efficiency of up to 91.42% means less loss and lower temperature. Add in a 140 mm fan and you get a power supply focused on stability and practicality, rather than flashy RGB.

What you get
With real 850W on the DC 3.3/5/±12 V lines and Active PFC, this PSU is prepared for modern, power-hungry systems, including current graphics cards with a PCI-E 5.1 connector. The ATX 3.1 standard is important because it ensures compatibility with PCIe Gen 5 GPUs and better management of peak loads, reducing the risk of instability during sudden spikes in consumption. Thanks to the full modular design, you only connect the necessary cables – better airflow, easier installation, and less cable chaos in the case. Working with a 100–240 VAC input means the power supply is safe for our electrical grid and is ready for more unstable power sources. The 80 PLUS and Cybenetics Gold certification indicates that the efficiency is not just on paper, but has also passed additional independent tests.

• Power 850W – enough for high-end CPU and powerful GPU, plus several additional devices, without worrying about wattage shortages.
• 80+ Gold and Cybenetics Gold certification – high efficiency, less energy lost as heat, and potentially quieter operation under load.
• ATX 3.1 with PCIe Gen 5.0/5.1 – ready for the next generations of graphics cards, including through the PCI-E 5.1 connector.
• Full modular design – all cables are detachable, making assembly easier and providing better airflow and a cleaner interior.
• Connectors: 20+4 Pin ATX x1, 4+4 Pin ATX/EPS x2, PCI-E 5.1 x1, PCI-Express 6+2 pin x3, SATA x4, Molex x2 – covers a standard gaming build with a modern GPU, several drives, and peripherals.
• Efficiency up to 91.42% – lower consumption from the outlet at the same load and lower temperatures in the power supply.
• 140 mm fan – a larger fan allows for lower RPM for the same airflow, which helps for quieter operation.

Who it is suitable for
This power supply is a good fit for gaming configurations from mid to high-end, including with a PCIe Gen 5 graphics card, as well as for those planning upgrades and not wanting to think about a new PSU soon. It is also suitable for heavier workstations with several drives and a more serious CPU. If you are building an ultra-compact build or need something focused on aesthetics and RGB, here the focus is more on practicality and standards.

The combination of 850W, ATX 3.1 / PCIe 5.1, full modularity, and Gold efficiency makes the 1stPlayer ACK HA-850BA2 a reasonable choice if you want a power supply that keeps a modern system stable and remains relevant for the next upgrade.
