Corsair RM1000e Fully Modular Low-Noise ATX Power Supply (Dual EPS12V Connectors, 105°C-Rated Capacitors, 80 PLUS Gold Efficiency, Modern Standby Support) Black, 1000 Watts

Product Information

You can probably imagine that if these layers of film aren't rolled up perfectly tight, they can hum like a kazoo. Here too, Corsair has taken extra measures to make sure these capacitors do not make any noise by implementing additional quality control measures when sourcing components to build our power supplies. A 120mm rifle bearing fan with a specially calculated fan curve keeps fan noise down, even when operating at full load.

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.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. 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 Resonant LLC Topology with DC-to-DC Conversion: Provides clean, consistent power and enables use of more
energy-efficient sleep states.

Seven-Year Warranty: Your guarantee of reliable operation for peace of mind through multiple builds. The +12V can deliver 83.3 Amps via the single rail configuration, and 20A on both +3.3V and +5V rails. The majority of the supplied cables are flat ribbon style for ease of routing during the build phase. Corsair also supply cable ties, a regional specific power cable and screws for mounting. The 24-pin main power supply cable is braided as shown in the images above. 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!).PLUS Gold-Certified: Steady power output at up to 90% efficiency, and Cybenetics Platinum certified for lower power consumption, less noise, and cooler temperatures. Intel® ATX 3.0 Certified: Compliant with the ATX 3.0 power standard, supporting the PCIe Gen 5 platform and resisting transient power spikes. Klarna Bank AB (publ) is Authorised by the Swedish Financial Services Authority (Finansinspektionen) and is subject to limited regulation by the Financial Conduct Authority. Supports Modern Standby sleep mode for extremely fast wake-from-sleep times and better low-load efficiency. Finance is only available to permanent UK residents aged >18, subject to status, terms and conditions apply.
