Asrock PRO-850G, 850W 80 Plus Gold ATX 3.1 PSU

Asrock PRO-850G is an 850W ATX power supply from the more sensible mid-range class, aimed at modern gaming and workstation machines with more serious GPUs. It combines 80+ Gold certification with up to 90% efficiency and support for ATX 3.0/3.1 - PCIe Gen 5.0/5.1, so you are ready for the current graphics cards. It features a 12+4 Pin PCI-E (PCI-E Gen5 12VHPWR) connector, which is important if you are considering newer GPUs. The format is standard ATX, and the length of 140 mm helps it fit comfortably in more compact cases.

What you get: a stable power supply with 850W power and Active PFC, which maintains cleaner and more stable voltage under load. 80+ Gold and up to 90% efficiency mean less loss in heat, quieter operation under partial load, and less strain on the other components. The 12+4 pin PCI-E Gen5 12VHPWR connector is a direct plus if you are jumping to modern high-end GPUs without the need for adapters. With a 120 mm fan and a compact body of 140 x 150 x 86 mm, you have a balance between cooling and compatibility with most cases. The Molex and SATA connectors allow you to connect HDDs, SSDs, fans, and other peripherals without drama.

• Power 850W – sufficient for serious gaming configurations and powerful GPUs, without worrying about power shortages.
• 80+ Gold certification with up to 90% efficiency – lower power consumption and less heat under typical load.
• ATX 3.0/3.1 - PCIe Gen 5.0/5.1 – current standard for modern systems and new graphics cards.
• 1 x 12+4 Pin PCI-E (PCI-E Gen5 12VHPWR) – direct support for modern high-end GPUs without the need for additional adapters.
• 2 x 6+2 Pin PCI-E – flexibility for a wider range of graphics cards or additional GPU power supplies.
• 4 x 15 Pin SATA and 2 x 4 Pin Molex – enough power for drives, fans, and peripheral devices.
• 120 mm fan – standard size for better airflow and easier integration into most cases.
• Non-modular design – all cables are routed directly, simplifying installation if you don't mind a bit more cable management.
• Power supply 100 – 240 VAC – full compatibility with the electrical grid, regardless of where you will use it.
• Warranty 36 months – three years of peace of mind for the main power source in the system.

It is suitable if you are building a serious gaming or workstation machine with a powerful GPU and want ATX 3.0/3.1 and 12VHPWR without entering the prices of the highest class PSUs. It is also a good option for a future upgrade to newer graphics cards. It is not the best choice if you insist on fully modular cabling and a maximally clean interior without excess cables.

The combination of 850W, 80+ Gold efficiency, and ATX 3.1 with Gen5 12VHPWR makes Asrock PRO-850G a quite sensible choice for current and future configurations. You get a PSU that meets today's requirements and remains relevant for your next GPU upgrade.
