Power Supply 1St Player ACK 850W ATX 3.1 80+ Silver HA-850BA7 80 Plus Silver

Power Supply 1St Player ACK Silver 850W ATX 3.1

The 1St Player ACK Silver 850W (HA-850BA7) is an 850W ATX 3.1 power supply ready for PCIe 5.1, with a dedicated 12V-2x6 cable for new-generation graphics cards plus two PCI-E 8-pin cables. It is 80 PLUS Silver and Cybenetics Silver certified, with 90.47% efficiency at typical load.

It suits gaming PCs with a strong graphics card and a modern CPU: a single 12V rail of 70.8A (849.6W) delivers almost the full output, and a DC-DC converter with double forward topology keeps voltages stable under changing loads.

Inside are Teapo electrolytic capacitors, active PFC and a 140 mm hydraulic bearing fan. Protections include OVP, OPP, SCP, OCP, UVP and OTP, and the embossed cables are fixed (non-modular). At 145x150x86 mm it fits a standard ATX case.

Key features

• ATX 3.1 and PCIe 5.1 with 12V-2x6 - A direct 12V-2x6 cable (670 mm) for new-generation graphics cards plus two PCI-E 8-pin (6+2) cables for standard cards, following the ATX 3.1 standard.
• DC-DC converter - A DC-DC design with double forward topology regulates the 3.3V and 5V rails for precise voltages and good compatibility with modern systems.

• Teapo capacitors - Teapo electrolytic capacitors contribute to stable performance and long service life.
• Silver efficiency - 80 PLUS Silver and Cybenetics Silver certification with 90.47% efficiency at typical load, plus active PFC for efficient power conversion.

• Full protection set - OVP, OPP, SCP, OCP, UVP and OTP protect the PSU and components against over-voltage, over-power, short circuit, over-current, under-voltage and over-temperature.
• 140 mm hydraulic bearing fan - A large fan with a hydraulic bearing cools efficiently at relatively low speed for quiet operation and long life.
