AGT Series 850W Power Supply - 80+ Gold, Fully Modular

Our review of the AGT Series 850W Power Supply finds it best suited to PC builders who want high efficiency and quiet operation without a bulky unit. The single biggest reason to consider this unit is its combination of 80 PLUS Gold efficiency and a 10 year warranty, which together promise lower heat and long-term reliability for gaming rigs and workstation builds. Installation is straightforward thanks to the fully modular cables, and the compact 140mm depth makes it a practical fit for many mid-tower cases.

Key Features

• 80 PLUS Gold certified: Delivers higher efficiency and less waste heat, which helps keep system temperatures and energy bills lower during typical loads.
• 10 Year Warranty: Offers long-term peace of mind and indicates the brand's confidence in component longevity and build quality.
• Fully Modular Design: Allows users to connect only the cables they need, improving airflow and simplifying cable management inside the chassis.
• Ultra-quiet FDB Fan: Fluid dynamic bearing fan with intelligent speed control keeps acoustic noise low while providing effective cooling under load.
• Compact 140mm Size: High power output in a shorter form factor makes it compatible with many mid-size cases that struggle with deeper power supplies.
• Heavy-duty Protection: Built-in OVP/UVP/OPP/SCP/OCP/OTP protections guard the system against common electrical faults.

Who It's For

This power supply is aimed at gamers and PC enthusiasts who need reliable, efficient power for high-performance CPU and GPU combinations while keeping noise and case clutter to a minimum. The fully modular cabling and compact 140mm depth make it a practical choice for clean builds and cases with limited PSU space.

Users who want extreme overclocking headroom or boutique features like RGB and exotic connectors should check compatibility carefully; similarly, extremely small form factor builds that require SFX units will need a different solution. Those wanting the absolute cheapest no-frills supply for basic office PCs can also look elsewhere for lower cost options.

Pros & Cons

Pros

• High efficiency from 80 PLUS Gold certification reduces wasted power and heat.
• Long-term confidence with a 10 year warranty and robust protection circuits.
• Fully modular cabling improves airflow and makes installation neater and simpler.
• Quiet operation thanks to an FDB fan and honeycomb ventilation design.

Cons

• Not as small as SFX units, so it may not fit very compact mini-ITX cases despite the reduced 140mm depth.
• Does not include flashy extras like RGB controller features some builders expect.
