Power supply 1stPlayer PS-850BA7 PSU ATX 3.1 850W - ACK Silver

1stPlayer PS-850BA7 is an ATX power supply with 850W power and 80+ Silver certification, aimed at mid-range to high-end gaming and workstation configurations. The combination of ATX 3.1 / PCIe Gen 5.0/5.1 support and PCI-E 5.1 connector opens the door to modern high-power GPUs without adapters. An efficiency of up to 90.33% means less energy loss and lower temperatures compared to budget models. It also features a large 140 mm fan that handles heavier loads without needing to run at high speeds all the time.

What you get: sufficient stable 850W for systems with a powerful CPU and serious GPU, along with a separate PCI-E 5.1 connector for next-gen graphics cards. Thanks to Active PFC and 80+ Silver efficiency, the power supply uses input voltage 100–240 VAC more wisely, helping to reduce consumption from the outlet at the same load. The two 4+4 Pin ATX/EPS provide an option for motherboards and processors that require additional CPU power, while the presence of PCI-Express 6+2 pin x 2 covers standard GPU configurations. Although it is not modular, the ATX form factor and compact length of 145 mm help it fit without drama in most mid-tower cases.

• 850W power provides enough headroom for powerful graphics cards and multi-core processors, plus additional devices and upgrades.
• 80+ Silver certification and up to 90.33% efficiency mean less heat loss and more stable voltage holding under load.
• ATX 3.0/3.1 with PCIe Gen 5.0/5.1 support allows you to power new GPUs through the PCI-E 5.1 connector without the need for additional adapters.
• PCI-Express 6+2 pin x 2 provides flexibility for popular graphics cards that still use standard 8-pin connectors.
• Two 4+4 Pin ATX/EPS are convenient for motherboards with additional CPU power input, especially for higher-end processors and overclocking.
• SATA x 4 and Molex x 2 cover a standard set of SSDs, HDDs, fans, and peripherals in a gaming or workstation build.
• 140 mm fan combined with compact dimensions 150 x 145 x 86 mm offers good airflow and easy integration into most ATX cases.

It is suitable if you are building a modern gaming or productivity computer with an option for a more serious GPU, including next-gen ones with PCIe 5.1 power. It is also a good choice for an upgrade from a weaker or uncertified PSU when you want more power and better efficiency. If you are aiming for super clean cable management or frequently change configurations, the lack of modularity may not appeal to you.

The most sensible aspect here is the combination of 850W, 80+ Silver efficiency, and ATX 3.1 / PCIe 5.1 support in a standard ATX format – you get a power supply that easily handles today's build and is ready for your next GPU.
