About this deal

I recommend getting a fully modular PSU since it offers total control of your build’s cable management. Efficiency Rating

A 120mm rifle bearing fan with a specially calculated fan curve keeps fan noise down, even when operating at full load. Electrolytics: 7x Elite (2-5,000h @ 105°C, EK), 1x Elite (4-10,000h @ 105°C, EY), 2x Suncon (2-5,000h @ 105°C, MF) Polymers: Suncon, Elite, NIC Most gaming builds will need power ranging between 450 to 650 watts unless you use a powerful GPU like the recently released RTX 4090. 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

The PSU controls the system’s power supply for optimal performance and protection, making it the heart of any gaming PC build. 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. 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. 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.

A non-modular PSU has all the cables permanently attached, while a fully modular design has no cables attached. My favorite feature about it is the zero RPM fan mode that offers near-silent operation at low to medium loads. Pros: Reliable and efficient low-noise power supply with fully modular cabling, so you only have to connect the cables your system build needs. Compliant with the ATX 3.0 power standard from Intel®, supporting the PCIe Gen 5 platform and resisting transient power spikes.

80 PLUS Gold-Certified

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. 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. Since the new era GPUs require more power— especially the RTX 4000 series, an ATX 3.0 PSU ensures your build is future-proofed for power-hungry GPUs. Color

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. 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 It’s almost impossible to find a non-modular 850W PSU. But some manufacturers design semi-modular ones which are affordably priced. But some manufacturers also design them in white colors to cater to builders looking to build sleek, all-white gaming PCs.

Apple please watch this.

Almost all PSU manufacturers design PSUs with the 80 Plus efficiency rating certification. The “80 Plus” rating system is the industry standard! 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: Corsair's new RM (without the "x") line consists of three members with capacities ranging from 650W to 850W. All of them are more affordable versions of the corresponding RMx models, which we expect to be updated in the near future to be fully compatible with the latest ATX specification. The RM units mostly use Chinese Elite caps, which are of decent quality, instead of the superior Japanese Nichicon and Chemi Cons and employ Hong Hua rifle bearing fans instead of Corsair's more-powerful NR135L. These changes might not be welcome by PSU enthusiasts, but the fact is that they don't seem to affect the product's lifetime since Corsair provides exactly the same warranty period (ten-years), in both RM and RMx units.
