Review SEA SONIC Seasonic G series Gold Semi modular Psu Active Pfc

The SeaSonic G-Series SSR-450RM PFC 80 Gold certified 450W Semi-Modular Power Supply Unit (PSU) is an excellent choice for PC builders seeking high-quality and efficient power solutions. This particular model, SeaSonic G-450W, is a part of the renowned G-Series line and is known for its reliability, performance, and quiet operation.

The PSU utilizes SeaSonic's renowned Fluid Dynamic Bearing (FDB) fan, which ensures quiet and efficient cooling. The fan only spins when necessary, providing near-silent operation under typical loads. This fan also has a longer lifespan than sleeve bearing fans, ensuring long-lasting performance.

The PSU boasts an 80 Gold certification, meaning it achieves an efficiency of at least 90% under typical loads, and 87% at 20% load, making it an energy-efficient choice. This also helps reduce your system's carbon footprint and saves you money on electricity bills.

The unit is semi-modular, which means it comes with detachable cables for the secondary side components (such as PCIe and peripheral cables) while keeping the primary side cables (like the 24-pin ATX and EPS12V) permanently attached. This design provides better cable management and reduces clutter inside the case, making it easier to install and maintain.

The SeaSonic G-450W supports modern PC components, including Multi-GPU setups and high-performance graphics cards, ensuring compatibility with a wide range of systems. Its 450W capacity also makes it suitable for high-end gaming rigs and workstations.

Additionally, the PSU includes a Protective Short-Circuit Prevention function, Over Voltage Protection, Under Voltage Protection, Over Power Protection, and Over Temperature Protection, ensuring your system and components are protected against various power-related issues.

In conclusion, the SeaSonic G-450W is a high-performance, efficient, and reliable Semi-Modular 80 Gold certified PSU that is perfect for PC builders seeking a quiet and energy-efficient power solution for their high-end gaming rigs or workstations.

The Seasonic SSR-450RM (PFC) and the SeaSonic G-Series SG-450W (SSR-450G) are both high-quality power supplies (PSUs) from the reputable manufacturer, Seasonic. Both models offer 450 watts of power and have 80 Bronze certification, which ensures a minimum efficiency of 82% under normal loads. However, they have some key differences that may influence your purchasing decision.

**Seasonic SSR-450RM (PFC):** Pros:

1. Fully Modular Design: All cables can be removed from the PSU, making cable management easier and allowing for customization based on the user's system configuration.

2. Active PFC: This feature allows the power supply to maintain a constant voltage level, even when the power drawn from the wall varies. It also helps improve the power supply's efficiency.

3. Quiet Operation: Seasonic's Fan Control technology regulates fan speed based on the load, ensuring quiet operation under normal conditions.

4. 10-Year Warranty: Seasonic offers a 10-year manufacturer's warranty for this PSU.

Cons:

1. Higher Cost: Fully modular power supplies tend to be more expensive than their semi-modular counterparts.

**Seasonic SG-450W (SSR-450G):** Pros:

1. Semi-Modular Design: Only the essential cables are hardwired to the power supply, allowing the user to choose which peripheral cables to connect and use.

2. Cost-Effective: Being a semi-modular design, it is generally more affordable than a fully modular power supply.

Cons:

1. Less Customizable: With fewer modular cables, cable management may be less efficient, and users may not have the same level of freedom to customize their cable setup.

2. Noise Level: While still quiet under normal loads, the fan in the G-Series may run louder under heavy loads compared to the SSR-450RM.

3. Shorter Warranty: The G-Series comes with a 5-year manufacturer's warranty.

**Conclusion:**

Both the Seasonic SSR-450RM (PFC) and the Seasonic SG-450W (SSR-450G) are excellent choices for powering a system. The primary difference between the two lies in their modularity. The SSR-450RM offers a fully modular design with more customizability and a longer warranty, while the SG-450W is semi-modular, more cost-effective, and less customizable.

If you value the flexibility and ease of cable management, the fully modular Seasonic SSR-450RM (PFC) might be the best option for you. However, if you're looking for a more affordable solution and are less concerned about cable management, the semi-modular Seasonic SG-450W (SSR-450G) could be a suitable choice. Ultimately, the decision comes down to your specific requirements and budget.
