The scores reflect both the strengths and potential pain points of this power supply, offering an unbiased, well-rounded view of its performance and value.

Efficiency
88%
Many users appreciate the power supply’s high efficiency with up to 88% energy conversion. This makes it a cost-effective option for those looking to reduce electricity bills and minimize waste heat, contributing to a cooler system overall. The 80 Plus Bronze certification is often cited as a key factor in its energy-saving benefits.
However, some users noted that despite the efficiency rating, the power supply may not be the most energy-efficient option in its class. Those looking for even higher efficiency may need to opt for higher-rated units like 80 Plus Gold models, which are not always as budget-friendly.
Performance Under Load
85%
The reliable continuous power delivery at 550W ensures stable performance even when the system is under load. Gamers and users running medium-level workstations have reported minimal fluctuations in power during demanding tasks. Many buyers find the steady performance reassuring for long-term use.
That said, a few users mentioned that under extremely heavy loads, the unit’s performance can slightly dip. While the performance is adequate for most users, those with high-end gaming rigs or demanding workstation setups may want to explore higher-wattage options for more headroom.
Noise Levels
91%
A standout feature for many buyers is the low-noise operation. The 120mm fan adjusts its speed based on load, which helps keep noise levels to a minimum, even during peak usage. Many users find it impressively quiet, making it an excellent choice for users sensitive to noise or those with quiet PC setups.
Some users did point out that the fan is not completely silent during high-demand tasks, with a faint hum becoming noticeable under heavy load. While the noise is not disruptive for most, users expecting total silence might find it slightly annoying in very quiet environments.
Build Quality
87%
The overall build quality is praised by users who appreciate the durability of the power supply. The solid construction, along with black sleeved cables and a sleek casing, give it a professional appearance. Buyers have reported that it feels sturdy and well-constructed, with minimal issues even after extended use.
However, a few users noted that while the unit feels solid, it doesn’t quite match the premium build quality of higher-end models. Some mentioned that the materials, while adequate, could be more robust, and the lack of additional protection like thermal cutoffs left some feeling uneasy about long-term durability.
Value for Money
92%
This power supply is often highlighted as an excellent value for money, offering good performance and energy efficiency at a relatively affordable price point. Buyers feel they get a reliable, well-built product without having to overspend. For most moderate builds, this unit is seen as a great balance between performance and cost.
Some buyers felt that while the unit offers great value, it may not be the best investment for users with high-demand setups or future-proofing concerns. Those seeking features like modular cables or higher wattages might find better alternatives in a higher price range.
Ease of Installation
84%
Many users found the installation process to be straightforward and hassle-free. The non-modular design, while limiting cable management options, makes it simple for users who don’t need a highly customized setup. The compact ATX form factor also ensures that it fits easily into most PC cases.
However, the non-modular design can be a downside for some users, as the extra cables can clutter the interior of the case, making cable management more difficult. While this isn't a major issue for many, those focused on aesthetics or working with smaller builds may find it a bit inconvenient.
Cable Management
70%
30%
Users who don’t prioritize aesthetics or high-level cable management generally found the included black sleeved cables functional. The cables are sturdy and blend well with most build color schemes, providing an acceptable balance between performance and appearance.
On the downside, the non-modular nature means that the cables are fixed, which can be frustrating for those trying to achieve a cleaner look or maximize airflow in compact cases. Some buyers noted that the excess cables can create clutter, especially in smaller cases.
Compactness & Compatibility
89%
The compact ATX form factor is a major selling point for users building in smaller cases. The unit fits well in most standard PC setups and leaves ample space for other components. It is also praised for being compatible with a wide range of systems, making it a flexible choice for both beginners and seasoned builders.
While it fits in most cases, a small number of users with very compact setups found it a tight squeeze. Some even noted that the power supply was slightly larger than anticipated, creating minor installation challenges in ultra-compact cases.
Longevity
86%
Many users report that this power supply holds up well over time, with few issues in terms of reliability. Those who’ve used it for extended periods often mention its stability and steady performance without noticeable degradation, making it a solid long-term investment for moderate builds.
However, a few users experienced early failures or minor power irregularities after a couple of years. While these incidents were rare, some buyers were concerned about the longevity of the product and questioned whether it would last under heavy, long-term usage.
Customer Support
80%
20%
Corsair’s customer support is generally considered responsive and helpful by most users. Buyers appreciated the quick responses to inquiries and the company’s willingness to assist with warranty claims. Many found it easy to reach out and get the help they needed.
On the other hand, a few users had mixed experiences with the support team. Some reported delays in response times or issues with the warranty process, leading to frustration. While support is decent, it doesn't always meet the expectations of those facing issues with the product.
Heat Dissipation
82%
18%
The heat dissipation performance is generally adequate, and the power supply does not overheat easily under normal load. The 120mm fan does a decent job of keeping temperatures in check during regular use, especially in systems that aren’t overly demanding.
However, some users running more intensive setups noted that the power supply can get warm under heavy loads. While it doesn’t overheat, users with high-performance PCs might experience higher temperatures, which could lead to concerns about long-term efficiency and component longevity.
Non-Modular Design Convenience
75%
25%
The non-modular design is appreciated by users who prefer simplicity and don’t mind having the extra cables. For those who prioritize a quick and easy setup, this design can be a convenient choice, offering reliable power without the complexity of modular cables.
The trade-off for this simplicity, however, is that the extra cables are not removable, leading to clutter and potentially compromising airflow in smaller builds. Some users expressed dissatisfaction with the lack of flexibility, preferring modular units for better cable management and a cleaner look.
