Corsair 550W RM-550 ATX Power Supply, 80 PLUS Gold Certified - Full Modular
Reliable operation, fully modular cabling, and optimized for silence.
The Corsair RM550 is fully modular and optimized for silence and high efficiency. It’s built with low-noise capacitors and transformers, and Zero RPM Fan Mode ensures that the fan doesn’t even spin until the power supply is under heavy load. And with a fan that’s custom-designed for low noise operation, it’s whisper-quiet even when it’s pushed hard.
80 PLUS Gold rated efficiency saves you money on your power bill, and the low-profile black cables are fully modular, so you can enjoy fast, neat builds. And, like all Corsair power supplies, the RM550 is built with high-quality components and is guaranteed to deliver clean, stable, continuous power. Want even more? Connect it to your Corsair Link system (available separately) and you can even monitor fan speed and +12V current directly from your desktop.
High-quality, low-noise capacitors and transformers
RM Series power supplies are designed with capacitors and transformers carefully selected to eliminate coil whine and other background noise that can be annoying in quiet environments.
Zero RPM Fan Mode
The efficient design of the RM550 means minimal excess heat generation, so the fan doesn't even need to spin under low to medium loads. And when you're pushing it hard, the thermal sensor controls the fan speed to ensure that it gets the cooling it needs without any extra noise.
Corsair NR135L Noise-Reducing Fan
The custom-designed fan has an optimized blade profile for low-turbulence airflow and near-silent operation even at full speed.
80 PLUS Gold-certified efficiency
Highly efficient RM Series power supplies produce less heat and have lower operating costs.
Flat black, low-profile modular cables
You can use only the cables you need, and leave the rest in the box for fast, easy, and great-looking builds.
Reliable, continuous power delivery
Power ratings are continuous, not peak, for superior protection for your valuable PC. Corsair uses high-quality internal components, and the RM550 is guaranteed to deliver clean, stable, continuous power.
