Power Supply Aigo AT850 PSU 850W 80 Plus Bronze

The Aigo AT850 is an 850W ATX power supply with an 80+ Bronze certification, aimed at mid-range to more serious gaming and workstation configurations. The combination of active PFC and 80+ Bronze means better efficiency compared to budget no-name PSUs and lower heat generation under normal load. The format is standard ATX, so it fits most cases without surprises, and the 120 mm fan handles the cooling. The black chassis and compact dimensions provide flexibility in more compact builds.

What you get: 850W of power is more than sufficient for a system with a modern mid-range to high-end GPU and a multi-core CPU, plus several SSD/HDD drives and peripherals, without being on the edge of the power supply's capabilities. Active PFC and dual-channel DC-to-DC design help keep the lines more stable during sudden changes in load – for example, spikes in consumption during gaming or rendering. The available PCI-Express 6+2 pin x 2 connectors are enough for most single-GPU configurations, while the 4+4 Pin ATX/EPS x 2 cover modern motherboards with more serious CPU power delivery. Taiwanese electrolytic capacitors also contribute to stability, as does the full set of protections, so that in case of a short circuit, overvoltage, or overheating, the PSU shuts down instead of taking something else down with it.

• 850W Power – suitable for configurations with a powerful GPU and multi-core CPU, without the PSU constantly operating at maximum.
• 80+ Bronze certification – better efficiency compared to basic models, less excess heat, and lower power consumption under typical load.
• Active PFC and dual-channel DC-to-DC design – more stable voltages under dynamic load, useful for gaming, streaming, and rendering.
• PCI-Express 6+2 pin x 2 – allows powering most modern graphics cards with a single GPU without the need for adapters.
• 4+4 Pin ATX/EPS x 2 – flexibility for motherboards with additional CPU power, typical for more serious platforms.
• SATA x 4 and Molex x 2 connectors – enough connections for SSDs, HDDs, fans, and additional peripherals in a standard build.
• Full set of protections: OPP/OVP/UVP/SCP/NLP/OTP – the PSU monitors for overload, overvoltage, undervoltage, short circuit, no-load, and overheating to protect the rest of the hardware.
• 120 mm fan – standard size for balanced cooling and a more predictable noise level.
• 100–240V full-range input – operates stably over a wide range of mains voltage, useful for less stable installations.

Who it is suitable for: if you are building a mid-range or more powerful gaming PC with a single graphics card and want an 850W PSU with decent efficiency and basic protections, this power supply fits right there. It is also a good choice for a workstation with many drives and additional devices, as long as you are not chasing the highest levels of efficiency and a completely silent profile.

The combination of 850W power, 80+ Bronze, active PFC, DC-to-DC design, and a full package of protections makes the Aigo AT850 a sensible choice if you are looking for a stable ATX power supply without unnecessary extras, but with a focus on basic reliability.
