ASRock Pg 1600G Atx 3.1 1600W Pcle5.1 Capacitor Japanese Fully Modular Phantom G vs CORSAIR SF850

Overview of Power Supplies

When comparing the ASRock Pg 1600G and the CORSAIR SF850, we see two high-quality power supplies that cater to different needs. The ASRock Pg 1600G is priced at C$304.99, while the CORSAIR SF850 is slightly more affordable at C$279.99. Both offer advanced features, making them suitable for modern gaming PCs and high-performance systems.

Build Quality and Reliability

The ASRock Pg 1600G is built with 100% highly reliable Japanese capacitors, which contribute to its durability and performance. In contrast, the CORSAIR SF850 also utilises 105°C rated Japanese capacitors, ensuring unwavering power and reliability. The choice of high-quality components in both power supplies indicates a commitment to longevity and stable power delivery, making either choice a solid investment.

Power Rating and Efficiency

The ASRock Pg 1600G boasts a powerful 1600W capacity and holds an 80 PLUS GOLD certification, which signifies high energy efficiency. On the other hand, the CORSAIR SF850, with its 850W capacity, is rated at 80 PLUS Platinum, offering even greater efficiency. The difference in power ratings means that while the ASRock can support more demanding setups, the CORSAIR excels in power efficiency, which could lead to lower electricity costs over time.

Modular Design

Both power supplies feature fully modular cable designs, facilitating neat cable management and optimising airflow in your case. The ASRock Pg 1600G features a native 12V-2x6 connector and a dual colour design, while the CORSAIR SF850 is designed with Type-5 Micro-Fit PSU connectors. This distinction may influence users who prioritise aesthetics and space efficiency in more compact builds.

Form Factor and Compatibility

In terms of form factor, the ASRock Pg 1600G has dimensions of 7.09 in × 5.91 in × 3.39 in, making it suitable for standard ATX cases. Meanwhile, the CORSAIR SF850 is designed in a compact SFX form-factor, which is ideal for small-form-factor PCs. This makes the CORSAIR more versatile for users looking to save space or build in smaller cases, whereas the ASRock is better suited for larger setups.

Cooling Solutions

Cooling is a critical factor in power supply performance. The ASRock Pg 1600G incorporates a 135mm striped axial FDB fan with iCool intelligent fan control, which adjusts fan speed based on temperature, ensuring efficient operation. In comparison, the CORSAIR SF850 utilises a 92mm PWM cooling fan that provides powerful cooling with low noise levels. Users may prefer the quieter operation of the CORSAIR in compact builds, while the ASRock’s larger fan may be more effective in dissipating heat in high-performance scenarios.

Warranty and Customer Support

The ASRock Pg 1600G comes with a global 10-year warranty, reflecting the manufacturer's confidence in its product's longevity and reliability. In contrast, the warranty details for the CORSAIR SF850 are not specified in the provided data. A longer warranty can be a significant factor for consumers, as it offers peace of mind regarding product durability and support.

Which should you buy?

Deciding between the ASRock Pg 1600G and the CORSAIR SF850 ultimately depends on your specific needs. If you require a high-capacity power supply for a demanding system and prefer longer warranty coverage, the ASRock Pg 1600G is an excellent choice. However, if you are looking for a more compact solution with superior energy efficiency and potentially quieter operation, the CORSAIR SF850 stands out. Both power supplies are reliable options, but your choice should align with your system requirements and personal preferences.
