Details about the extent of our regulation by the Financial Conduct Authority are available from us on request. 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. PLUS Gold-Certified: Steady power output at up to 90% efficiency, and Cybenetics Platinum certified for lower power consumption, less noise, and cooler temperatures. The Corsair RM1000e (2023) has actually really impressed me. I am often not sure what to expect from Corsair power supplies, as over the years they have proven sometimes to be a little ‘hit and miss', especially with their more budget offerings. ‘Hang on!' I hear you shout, ‘surely you aren't saying this 1000W unit is a ‘budget' PSU'?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... We've found that, under certain circumstances, these types of capacitors can make more noise than any others. Why? 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. The Corsair RM1000e 2023 chassis is colour neutral and suited for any system themed build you might have in mind. The load regulation of this power supply is solid throughout, with only minor dip on the +12V rail. Corsair RM1000e
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. Seven-Year Warranty: Your guarantee of reliable operation for peace of mind through multiple builds.

Resonant LLC Topology with DC-to-DC Conversion: Provides clean, consistent power and enables use of more energy-efficient sleep states. The efficiency results are excellent, peaking at 92.6% at close to 55% load. This drops to just under 90% efficiency at full load. These are really very positive results for an 80 Plus Gold rated unit.
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. Reliable and efficient low-noise power supply with fully modular cabling, so you only have to connect the cables your system build needs. 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. 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. PLUS Gold certified for steady power output at up to 90% efficiency, and Cybenetics Platinum certified for lower power consumption, less noise, and cooler temperatures. The primary stage has a single Taiwanese 105c rated Elite Jinshan cap. These caps are pretty good, even if they fall a bit short of the highest grade caps from Japanese brands such as Nippon Chemi Con or Rubycon. 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
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. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and enables use of more energy-efficient sleep states. 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.

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. 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 transformer on the left is measuring a diameter of 32.8mm, which is good. But the one on the right is measuring 34.08mm despite the same length of copper wire is wound around the core. This means the windings are not as tight as they could be, the transformer could potentially make a noise, and is therefore rejected. We test ambient temperatures at 35c in our environment to greater reflect warmer internal chassis conditions. The +12V can deliver 83.3 Amps via the single rail configuration, and 20A on both +3.3V and +5V rails.
