Certification, Specs and Features
Certification
Corsair offers a 80+ Gold certification, tested by the 80PLUS organization (the people that certify and test efficiency). We already explained a little what that literally means. But what does such a certification entail?
Well, we have standard, bronze, silver, gold, and platinum certifications. A PSU that is certified 80 PLUS Gold or 80 PLUS Platinum is more efficient than a normal unit. Below youll find a table that shows what efficiency levels a PSU has to achieve at a given load to make the grade for a specific certification level.
Efficiency at 20% Load | Efficiency at 50% Load | Efficiency at 100% Load | |
---|---|---|---|
80 PLUS | 80% | 80% | 80% |
80 PLUS Bronze | 82% | 85% | 82% |
80 PLUS Silver | 85% | 88% | 85% |
80 PLUS Gold | 87% | 90% | 87% |
80 PLUS Platinum | 90% | 92% | 89% |
The Corsair RM 650 850 power supplies are certified by the 80PLUS organization to deliver a 90% energy efficiency at 50% load (which equals a Gold label). We are not 100% certain if the product complies with the ErP (Energy Related Product) directive to ensure less than 1W of power is used in passive standby and off modes. We'll test that manually later on in the article.
Above, you can see a diagram of how the PSU behaves efficiency wise.

The Corsair RM650 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 RM650 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.
