Review SEASONIC Plus Gold Psu Full Modular Atx 850w Power Supply

The Seasonic SS-850 Kumo Power Supply Unit (PSU) is a top-tier modular ATX solution designed to deliver an impressive 850 watts of power with 80 Plus Kumo Platinum certification. This efficiency level ensures that up to 94% of the input power is converted into usable electricity under typical loads, with up to 92% efficiency at 10% to 25% load and 91% at 50% load.

This modular design offers high flexibility, enabling users to install only the cables they need. This not only simplifies installation and cable management but also reduces clutter and potential obstructions in the case. The cables are flat and ribbon-like, which further enhances the neat appearance of the system and allows for easy cable routing.

The SS-850 Kumo PSU is built with a quartet of 12V rail design, ensuring stable and efficient power delivery to components that require a 12V power source. This design also makes it an excellent choice for systems with multiple high-performance graphics cards or other power-hungry components.

The Seasonic S12 II-80 fan is integrated into the PSU, with a fan control circuit that maintains near-silent operation until the power load reaches 40% or higher. The fan is also designed to have a long lifespan, ensuring quiet and reliable operation for years to come.

The PSU features a fully modular design, with a total of 13 cables and connectors, allowing for easy customization and clean cable management. The cables include 1 x 24-pin ATX main power cable, 1 x 4 4-pin EPS12V power cable, 2 x 6 2-pin PCIe power cables (each with 2 additional 6-pin PCIe connectors), and 10 x various SATA and peripheral power cables.

The SS-850 Kumo PSU is constructed using high-quality Japanese capacitors, ensuring stable voltage regulation and a long lifespan. The PSU also features a protective circuitry suite, which includes OVP (Over Voltage Protection), UVP (Under Voltage Protection), OCP (Over Current Protection), SCP (Short Circuit Protection), and OPP (Over Power Protection).

Overall, the Seasonic SS-850 Kumo is a high-performance, efficient, and reliable power supply unit designed for systems that require a large amount of power with maximum efficiency and flexibility. Its modular design, quiet operation, and long lifespan make it an excellent investment for enthusiasts, gamers, and professionals who demand the best from their power supplies.

The Seasonic SGX-850 80 Gold 850W modular ATX power supply unit (PSU) is a popular choice among PC builders due to its high efficiency, reliability, and modular design. Let's examine some of its pros and cons:

1. High efficiency: The 80 Gold certification ensures that the PSU converts at least 87% of the input power into output power under typical loads. This results in less heat production and improved energy efficiency.

2. Modular design: The modular design allows users to only connect the cables they need, reducing clutter inside the case and making cable management easier.

3. Quiet operation: The fan starts spinning only when the PSU reaches a certain temperature, ensuring quiet operation under normal loads.

4. High wattage: With a capacity of 850W, this PSU can power even high-end systems with multiple GPUs or overclocked CPUs.

5. Reliable: Seasonic is a well-known and respected manufacturer in the PSU industry, known for producing high-quality and reliable products.

1. Size and weight: Due to its high wattage and modular design, this PSU is larger and heavier than some other options in its class.

2. Cost: The Seasonic SGX-850 is more expensive than some other 850W PSUs on the market.

3. No semi-passive mode: Unlike some other high-end PSUs, this model does not have a semi-passive mode, meaning the fan always spins when the PSU is under load.

In conclusion, the Seasonic SGX-850 80 Gold 850W modular ATX power supply unit is a reliable and efficient choice for powering high-end PC systems. Its modular design, quiet operation, and high wattage make it an attractive option for many builders. However, its larger size, higher cost, and lack of semi-passive mode may be drawbacks for some users. Ultimately, if you're looking for a high-quality and powerful PSU that can handle even the most demanding systems, the Seasonic SGX-850 is a solid choice. If size, weight, or cost are major concerns, you may want to consider other options in the market.
