The ASRock Pg 1600G is priced at C$304.99, while the CORSAIR RM1000x SHIFT is more budget-friendly at C$264.99. Both offer fully modular designs, but they come with distinct features that cater to different preferences in cable management and overall performance.
Design and Build Quality
In terms of design, the ASRock Pg 1600G features a dual-color design and dimensions of 7.09 in × 5.91 in × 3.39 in. This power supply is constructed with 100% highly reliable Japanese capacitors, ensuring durability and consistent performance. On the other hand, the CORSAIR RM1000x SHIFT introduces an innovative side connection position for easier access and cleaner cable management. It also boasts a debossed PVC cable kit that enhances flexibility and aesthetics. While both power supplies focus on modularity, the ASRock's robust build quality versus the CORSAIR’s innovative design presents a choice between reliability and convenience.
Performance and Certification
When it comes to performance, the ASRock Pg 1600G holds an impressive 80 PLUS GOLD certification along with Cybenetics PLATINUM and LAMBDA A ratings, indicating superior efficiency and reliability under load. The CORSAIR RM1000x SHIFT is equally impressive, featuring fully modular connectors that are designed to power modern GPUs effectively. With a native 12V-2x6 GPU cable, it can seamlessly support the latest graphics cards, such as the NVIDIA GeForce RTX 50 Series. Both power supplies deliver excellent performance, but the ASRock may have a slight edge in certification ratings.
Cooling Solutions
Cooling is a critical factor for power supplies, and both models offer unique solutions. The ASRock Pg 1600G is equipped with a 135mm striped axial fan that employs TempGuard technology for optimal cooling and noise management. The iCool Intelligent Fan Control mode further enhances its efficiency. In contrast, the CORSAIR RM1000x SHIFT uses a 140mm fluid dynamic bearing fan, which is designed for high performance while operating quietly. Both cooling systems are engineered to maintain performance, but the ASRock's intelligent control features may appeal to users focused on temperature management.
Cable Management and Modularity
Both the ASRock Pg 1600G and CORSAIR RM1000x SHIFT excel in modularity, allowing users to connect only the cables they need. The ASRock features a fully modular cable design, which simplifies installation and cable management. Meanwhile, the CORSAIR model stands out with its innovative side connections that make access easier and promote a cleaner build. Additionally, the smaller size of the CORSAIR Type-5 PSU cables offers more room for effective cable routing. While both products facilitate good cable management, the CORSAIR's design may provide a more streamlined experience.
Reliability and Warranty
Reliability is paramount when choosing a power supply, and both brands offer strong assurances. The ASRock Pg 1600G is backed by a global 10-year warranty, reflecting its confidence in the product's durability and performance longevity. The CORSAIR RM1000x SHIFT, while not specifying a warranty period in the provided details, is known for its robust build quality and reputation within the industry. The lengthy warranty of the ASRock model may appeal to users looking for long-term reliability and peace of mind.
Pricing and Value
In terms of pricing, the ASRock Pg 1600G is priced at C$304.99, which positions it as a premium option. Conversely, the CORSAIR RM1000x SHIFT is more affordable at C$264.99, making it a compelling choice for budget-conscious consumers. While both power supplies deliver quality and efficiency, the lower price point of the CORSAIR may attract users who are looking for value without sacrificing too much in terms of performance and features.
Which should you buy?
Choosing between the ASRock Pg 1600G and the CORSAIR RM1000x SHIFT ultimately depends on your specific needs and preferences. If you prioritise certification ratings, reliability, and a robust build with a long warranty, the ASRock Pg 1600G is the better option for you. However, if you seek a more budget-friendly choice with innovative cable management solutions and effective cooling, the CORSAIR RM1000x SHIFT is a strong contender.
