Another source of so-called "coil whine" is actually from capacitors. While many people think that a capacitor that's making noise is a leaking capacitor, the truth is that a capacitor can make a noise similar to "coil whine" for the same reason a coil or transformer will make these noises. The inside of a capacitor is made up of a dielectric material and a metallic film. These two thin layers are rolled up to form the capacitor. Once again, tolerances are important. If there is any non-uniformity in the coil of two layers, a mechanical resonance can occur that produces a high pitched noise. Coil whine" has become a generic term for audible electrical noises. The fact of the matter is, there's a very good chance that these types of noises aren't coming from a coil at all. One component, similar to a coil in construction, is the transformer. A power supply can have several of these and the windings can vibrate under certain frequencies just like they can with any coil. Again, an attempt is made to wind the wire tighter around the transformers core and use varnish and even tape to help isolate any vibration and potential noise.
The modular bay is home to a plethora of solid capacitors for output filtering. The unit also has OVP, OCP, SCP, OPP and OTP protections in place. The load regulation of this power supply is solid throughout, with only minor dip on the +12V rail. Corsair RM1000e The +12V can deliver 83.3 Amps via the single rail configuration, and 20A on both +3.3V and +5V rails. Next we want to try Cross Loading. This basically means loads which are not balanced. If a PC for instance needs 500W on the +12V outputs but something like 30W via the combined 3.3V and +5V outputs then the voltage regulation can fluctuate badly. Cross Load Testing PLUS Gold-Certified: Steady power output at up to 90% efficiency, and Cybenetics Platinum certified for lower power consumption, less noise, and cooler temperatures.Reliable and efficient low-noise power supply with fully modular cabling, so you only have to connect the cables your system build needs. The Corsair RM1000e handled our cross load test very well, holding stable results across the range. The rear of the box highlights some key features, including the zero RPM mode, low noise characteristics. We've found that, under certain circumstances, these types of capacitors can make more noise than any others. Why?
You can see we have a copper wire wound around a central core (I got a little aggressive with the knife and ended up cutting some of the copper windings, but there was a lot of tape wrapped around there!). The RMe series is more affordable than the RMx line, offering in its newest revision ATX v3.0 and PCIe 5.0 compatibility. The RM1000e uses an efficient platform and it also has a silent operation. Performance wise, don’t expect it to be close to the RMx line, because this would create internal competition. Compliant with the ATX 3.0 power standard from Intel®, supporting the PCIe Gen 5 platform and resisting transient power spikes. Corsair have opted for their traditional bright yellow box artwork with an image of the unit on the front.Today to test the Power Supply we have taken it into our acoustics room environment and have set our SkyTronic DSL 2 Digital Sound Level Meter (6-130dBa) one meter away from the unit. We have no other fans running so we can effectively measure just the noise from the unit itself. What we've started to do at Corsair is carefully vet our manufacturer of transformers to not only meet performance criteria, but also to meet the criteria we know will give our customers zero noise in their power supply.
