Cooler Master V850 SFX Gold vs Corsair HX1000i Fully Modular Ultra-Low Noise ATX Power Supply - ATX 3.1 & PCIe

Overview of the Power Supplies

When it comes to high-quality power supplies, the Cooler Master V850 SFX Gold and the Corsair HX1000i stand out for their performance and efficiency. The V850 SFX Gold is priced at £134.56, making it a more budget-friendly option compared to the HX1000i, which retails at £169.99. Both units promise excellent performance, but their design and features cater to different types of users and builds.

Size and Form Factor

The Cooler Master V850 SFX Gold is specifically designed for small form factor (SFF) mini-ITX PC cases, boasting compact dimensions of 100 x 125 x 63.5 mm. This makes it an ideal choice for those looking to build a mini-PC without sacrificing power. In contrast, the Corsair HX1000i is an ATX power supply, which may be better suited for larger builds. Users with space constraints may find the V850 SFX Gold more appealing due to its smaller footprint.

Efficiency and Performance

Efficiency is a critical aspect of any power supply, and the Cooler Master V850 SFX Gold shines with its 80 PLUS Gold certification, achieving 90% efficiency under typical loading conditions. This level of efficiency not only saves on utility costs but also helps to reduce heat accumulation, contributing to a cooler system. The Corsair HX1000i, while not specifically rated in the provided data, is Intel ATX 3.1 certified, which indicates a high level of performance. However, the exact efficiency rating is not specified, making the V850 SFX Gold a clearer choice for users prioritising efficiency.

Cable Management

Cable management is essential for maintaining a clean and efficient build, and both power supplies offer fully modular cabling. The Cooler Master V850 SFX Gold includes a variety of connectors, enabling sophisticated case builds that improve internal airflow. Meanwhile, the Corsair HX1000i also features fully modular cabling, allowing users to connect only the necessary cables, which further simplifies the building process. While both options excel in this area, the comprehensive connector options of the V850 SFX Gold may provide an advantage for more complex configurations.

Noise Levels

When it comes to noise levels, both power supplies are designed with user comfort in mind. The Cooler Master V850 SFX Gold employs a 92mm fluid dynamic bearing (FDB) fan that operates quietly and includes a semi-fanless mode for loads under 15%. This ensures that the power supply remains almost silent during light usage. The Corsair HX1000i takes it a step further with its 140mm FDB fan, which also delivers quiet performance. Additionally, it features a Zero RPM Fan Mode that completely shuts off the fan at low and medium loads, making it an excellent choice for users seeking near-silent operation.

Build Quality and Durability

Durability is a crucial factor in choosing a power supply, and the Cooler Master V850 SFX Gold is built to last with 100% Japanese capacitors and a 10-year standard warranty. This commitment to quality provides users with peace of mind regarding long-term performance. The build quality of the Corsair HX1000i is also robust, but specific details about its components are not provided in the data. Thus, while both units promise reliability, the V850 SFX Gold’s explicit mention of high-quality capacitors and an extended warranty may offer a slight edge in long-term confidence.

Compatibility

Compatibility is an important consideration, especially with the rise of newer technology standards. The Corsair HX1000i is compliant with the ATX 3.1 power standard, making it suitable for the latest PCIe Gen 5.1 platforms and capable of resisting transient power spikes. The Cooler Master V850 SFX Gold, while not specifically mentioned in relation to ATX standards, is designed for SFF builds but can also be installed in ATX cases with an SFX-to-ATX bracket. Users looking to future-proof their systems may prefer the Corsair HX1000i due to its adherence to the latest standards.

Which should you buy?

Choosing between the Cooler Master V850 SFX Gold and the Corsair HX1000i ultimately depends on your specific needs. If you're building a compact mini-ITX system and value efficiency, the V850 SFX Gold is an excellent choice at £134.56, thanks to its 80 PLUS Gold rating and compact size. On the other hand, if you're constructing a larger ATX build and require the latest technology standards along with ultra-low noise operation, the Corsair HX1000i, priced at £169.99, offers features that cater to these needs. Both power supplies excel in their respective niches, ensuring users can find a suitable option based on their requirements.
