Introduction and Features

2-RM-Series-Banner.jpg

Corsair offers a full line of high quality power supplies, memory components, cases, cooling components, SSDs and accessories to the PC market.  Corsair's new RM Series includes six models; the RM450, RM550, RM650, RM750, RM850 and RM1000.  All of the power supplies in the RM Series feature all-modular cables, an energy-efficient design (80 Plus Gold certified) and quiet operation thanks to their ability to run without a cooling fun up to 40% load. The RM Series offers many of the same features as the Corsair HX Series (fanless operation, Gold level efficiency, fully-modular cables) but are a little less expensive. And all RM Series power supplies are Corsair Link ready, which means you can monitor the PSU fan speed and +12V output right from your desktop if you have a Corsair Link system set up on your PC. Previously the Corsair Link option was only available on Corsair’s premium AX Series Digital power supplies.

Here is what Corsair has to say about their RM550 PSU we will be looking at in this review: “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.

80Plus 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.

Corsair RM550 PSU Key Features:

• Silent, fan-less operation up to 40% load
• 80Plus Gold certified, delivering over 92% efficiency under real world loads
• Fully modular, low-profile flat cables help maximize case airflow
• Corsair Link ready!
• High-quality capacitors provide uncompromised performance and reliability
• Active PFC and Universal AC input (100-240 VAC)

Corsair Announces Nearly-Silent RM Series Power Supplies

Corsair has introduced its new RM series of power supplies. The new lineup replaces the TX series and sits between the existing HX and AXi series. RM-series PSUs are optimized for efficient and nearly silent operation.

The new fully modular RM series power supplies are 80 PLUS Gold certified and range from 450W to 1000W. The PSUs reportedly use low noise capacitors and transistors along with a 135mm fan that only starts spinning under high load (what Corsair calls the “ZeroRPM Fan Mode”) such as gaming. In addition to quiet operation, the RM series supports monitoring functionality. Using Corsair Link software, users can monitor PSU fan speed and power delivery. A cable, called the Corsair Digital Bridge Cable, runs from the PSU to either the system motherboard or a Corsair Link Hub and enables the monitoring features. This cable comes bundled with the highest-end RM1000 (1000W) unit, but is an additional charge for the other RM series.
