Bronze PSU
The SilverStone Essential ET550-B power supply is certified with the 80+ Bronze standard, ensuring good energy efficiency. It serves as an affordable alternative to premium models, providing stable performance for entry-level and mid-tier PCs with some power reserve for possible upgrades. Thanks to active power factor correction (PFC), the device demonstrates 85% efficiency at half load and maintains stability under full operation in a 24/7 mode. The well-thought-out design with heatsinks prevents overheating, while the protection system (OVP, OPP, OCP, SCP, OTP) safeguards components from unforeseen electrical failures. With a power of 550W, the PSU can endure a +12V rail load up to 504W. It can easily handle modern processors and graphics cards (e.g., AMD Ryzen 7 Granite Ridge 9700X OEM + Gigabyte Radeon RX 7600 XT GAMING OC 16G) while leaving room for overclocking.
Ease of Installation and Comfortable Operation
The compact ATX form factor allows for installation of the power supply in most standard cases, while extended cables ensure compatibility with full tower models. Flat, flexible cables are easily placed in hidden compartments, enhancing the system's internal appearance. The 120mm diameter fan adjusts airflow depending on the load, extending the bearing's lifespan and minimizing noise levels. With light loads, such as document work, photo viewing, or music playback, noise does not exceed 18 dB, ensuring comfortable operation.
