CORSAIR RM Series , RM650, Fully Modular Power Supply vs PCCOOLER PSU Fully Modular Power Supply, 850W ATX

Price Comparison

When it comes to price, the PCCOOLER PSU is significantly more affordable at $79.99 compared to the CORSAIR RM Series priced at $138.31. This makes the PCCOOLER about 43% cheaper than the CORSAIR model. For budget-conscious consumers or those seeking a cost-effective solution for their power supply needs, the PCCOOLER offers an appealing choice without sacrificing essential features. On the other hand, the CORSAIR RM Series, while pricier, is known for its robust build quality and reliability, which may justify the additional expense for some users.

Power Output

The power output is a crucial consideration for any power supply. The PCCOOLER PSU boasts an impressive 850W capacity, making it suitable for high-performance gaming rigs or workstations that require substantial power. In contrast, the CORSAIR RM Series provides 650W, which is still adequate for most mid-range builds but may limit the potential for future upgrades. This 200W difference can make a significant impact, especially when powering top-tier components. Users looking to maximize their system’s performance may lean towards the PCCOOLER for its higher wattage.

Modular Design

Both power supplies feature a fully modular design, allowing users to connect only the cables they need, which promotes cleaner builds and improved airflow. The CORSAIR RM Series emphasizes its fully modular capabilities, allowing users to customize their cable management easily. Meanwhile, the PCCOOLER PSU includes ultra-flexible shark-pattern cables that not only enhance aesthetics but also facilitate optimal airflow. This feature can be particularly beneficial for users who prioritize neatness in their setups or those who regularly upgrade components.

Efficiency Ratings

Efficiency is another critical factor in choosing a power supply. The CORSAIR RM Series is rated 80 PLUS Gold, ensuring up to 90% efficiency under typical loads, which translates to lower energy bills and reduced heat output. Similarly, the PCCOOLER PSU also holds an 80 PLUS Gold certification, delivering up to 92% conversion efficiency. This slight edge in efficiency may appeal to environmentally conscious users or those eager to reduce operating costs. Both power supplies offer excellent efficiency ratings, but the PCCOOLER’s marginally higher efficiency could be a deciding factor for some.

Cooling Performance

Cooling performance is essential in maintaining system stability and longevity. The CORSAIR RM Series features a 140mm rifle bearing fan designed to minimize noise, even under full load, with a zero RPM fan mode for silent operation during light use. Conversely, the PCCOOLER PSU incorporates a 120mm hydraulic bearing fan that intelligently adjusts its speed based on temperature, ensuring quiet operation during low loads while ramping up under heavy demand. Both units prioritize silence and efficiency, but the CORSAIR's larger fan may provide quieter operation at peak loads.

Component Quality

Component quality can significantly affect the reliability and lifespan of a power supply. The CORSAIR RM Series is built with industrial-grade, 105°C-rated capacitors, which promise solid electrical performance and reliability. On the other hand, the PCCOOLER PSU also boasts premium Japanese capacitors rated at 105°C, ensuring long-term stability and performance, especially in demanding scenarios. Both brands emphasize high-quality components, making them both reliable choices, though the reputation of the brand may sway some buyers towards the CORSAIR model.

Warranty and Support

Warranty and manufacturer support are vital for peace of mind when investing in a power supply. The CORSAIR RM Series comes with a generous ten-year warranty, reflecting the brand's confidence in the product's durability. Conversely, the PCCOOLER PSU offers a five-year warranty, which, while shorter, still provides ample coverage for users. A longer warranty can be a significant factor for those who plan on using the power supply for an extended period, making the CORSAIR a more attractive option for long-term users.

Which should you buy?

In deciding between the CORSAIR RM Series and the PCCOOLER PSU, it ultimately comes down to specific needs and budget. The PCCOOLER is an excellent choice for users seeking a cost-effective solution with higher wattage and solid features at a lower price point. However, those prioritizing brand reputation, longer warranty, and proven reliability may find the CORSAIR RM Series worth the extra investment. Each power supply has its strengths, making them both viable options depending on individual requirements.
