A 120mm rifle bearing fan with a specially calculated fan curve keeps fan noise down, even when operating at full load. I know it's not that evident in the video, but I managed to get the moment it starts up in a voice recording (0:03) : https://drive.google.com/drive/folders/1AX08uPUrxnzy9zlbAVo8QEyvGD82gGdI?usp=sharing Most gaming builds will need power ranging between 450 to 650 watts unless you use a powerful GPU like the recently released RTX 4090. Primary side: Half-Bridge & LLC converter Secondary side: Synchronous Rectification & DC-DC converters But SFX PSUs come in smaller designs to fit in small form factor (SFF) cases because they don’t have the space needed to fit a full-size ATX PSU.
It’s almost impossible to find a non-modular 850W PSU. But some manufacturers design semi-modular ones which are affordably priced. I presume you already have the estimated total wattage that your PC will draw, and an 850W PSU is the ideal power supply unit to complete the build. After deciding on the PSU wattage, the next thing you need to consider is the form factor. They’ll either come in the ATX or SFX form factor.It's the old discrepancy between case designers that put fan grids on the bottom, and PSU designers that always advise to put the fan up. At least now, most PSU shrouds are ventilated on the top to allow installation of the PSU in the correct orientation. The 80 Plus Gold efficiency rating is usually the sweet spot for most gaming PC builds. Anything above this is overkill and quite expensive! ATX 3.0 Compatible
The Corsair RM850x power supply is highly regarded by most builders. It’s fully modular and has an 80+ Gold efficiency rating. To be 80 Plus certified means that the PSU has at least 80% efficiency at three load levels of 20, 50, and 100 percent loading. ATX 3.0 is the new specification standard for PSUs. This new design adds a new PCIe 5.0 connector with 12 + 4 pins alongside the usual 6 or 8-pin connection.

Once you have decided on the form factor and modular design, the next thing you need to consider is the efficiency rating you can afford. But some manufacturers also design them in white colors to cater to builders looking to build sleek, all-white gaming PCs.
Supports Modern Standby sleep mode for extremely fast wake-from-sleep times and better low-load efficiency. A fully modular power supply unit lets you use only the cable you need for simple and clean cable management.
A non-modular PSU has all the cables permanently attached, while a fully modular design has no cables attached. I recommend getting a fully modular PSU since it offers total control of your build’s cable management. Efficiency Rating Almost all PSU manufacturers design PSUs with the 80 Plus efficiency rating certification. The “80 Plus” rating system is the industry standard!
The 80 Plus efficiency rating has since expanded in recent years to categorize different PSUs from the least to the most efficient. My favorite feature about it is the zero RPM fan mode that offers near-silent operation at low to medium loads. Pros: DC-DC Converters: 2x UBIQ QM3054M6 (30V, 61A @ 100°C, 4.8mOhm) & 2x UBIQ QN3107M6N (30V, 70A @ 100°C, 2.6mOhm) PWM Controllers: uPI SEMI uP3861P After almost three years in production, Corsair decided to update its popular RMx line. There are again five members with capacities ranging from 550 W to 1000 W. All are fully modular, and the OEM is still Channel Well Technology. Listed below are the crucial changes over the RMx 2018 units with the RMx 2021 revision:The new connector is meant to make the power supply PCIe 5.0 ready. They have high power delivery for GPUs with up to 600W of power. Reliable and efficient low-noise power supply with fully modular cabling, so you only have to connect the cables your system build needs. You’re more likely going to need an ATX power supply. That’s unless the case manufacturer specifically states you use an SFX one. Modular Design
