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

Supports Modern Standby sleep mode for extremely fast wake-from-sleep times and better low-load efficiency.

A large fan sits behind a grill on the top of the chassis. We will take a closer look at the fan when we open the chassis shortly. The Corsair RM1000e 2023 chassis is colour neutral and suited for any system themed build you might have in mind.This unit is an active PFC + half bridge LLC resonance and synchronous rectification + DC-DC design. The design implements independent PCBs for the DC-DC modules and synchronous rectification. The level one EMI adopts independent PCB design. This is equipped with a pair of Y capacitors and two X capacitors with a common mode inductor. The primary PCB contents the second level EMI circuit including a common mode inductor and a single X capacitor and a pair of Y capacitors. An MOV and NTC are also present. An independent relay is seen between the primary cap and the PFC circuit.

As expected, the cables supplied with the 1000W unit should cover any building requirements for the majority of users, including a PCIe 5.0/12VHPWR connector. The cables are long enough for even the biggest cases available on the market today. Reliable and efficient low-noise power supply with fully modular cabling, so you only have to connect the cables your system build needs. Above we have a picture of the main transformer and the +5VSB transformer out of our new RM Series power supplies. If we cut all of that tape off... Resonant LLC Topology with DC-to-DC Conversion: Provides clean, consistent power and enables use of more
energy-efficient sleep states. The Corsair RM1000e handled our cross load test very well, holding stable results across the range.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.

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. 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!). Finance is only available to permanent UK residents aged >18, subject to status, terms and conditions apply. Some power supplies exhibit noises that come from components other than the intake fan. These noises can sound like hissing, buzzing or a high pitched whine. These noises can come and go and can be difficult to troubleshot for a couple of reasons. One reason is that the noise can change, or be completely absent, depending on the load on the power supply. I'll get into more detail about that in a little bit, but what this does mean is that a PSU that makes a noise in one PC during one game or benchmark program may not make the same noise in another... or may make no noise at all. The other reason is that often these noises can be at such a high frequency that only some people are actually able to hear them. Many people, especially those over 25 years of age, cannot hear noises over 15kHz, while others can hear noises all of the way up to 20kHz. So you can have a PC sitting in a room, with a power supply that's making a high pitched squealing noise, and if two people are sitting in the same room; one of them may be able to hear the noise while the other one hears nothing at all. Aluminum electrolytic capacitors, the caps that look like little cans, are rolled up with an electrolyte soaked paper. That paper can actually absorb the mechanical resonance that can create noise. But the capacitors shown above use a metalized polypropylene as a dielectric. This "plastic film" can vibrate with certain frequencies, just like our copper windings on our coils and transformers, and produce a high pitched noise.We take the issue of noise very seriously at KitGuru and this is why we have built a special home brew system as a reference point when we test noise levels of various components. Why do this? Well this means we can eliminate secondary noise pollution in the test room and concentrate on components we are testing. It also brings us slightly closer to industry standards, such as DIN 45635.
