About this deal

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 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. 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.

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: 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. 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. 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 DesignThe PSU controls the system’s power supply for optimal performance and protection, making it the heart of any gaming PC build. 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.Simply put, an 850W 80 Plus PSU will draw a maximum of 1,062.5W at 100% load, which means less wattage is wasted as heat in the conversion process, saving your energy bill. A fully modular power supply unit lets you use only the cable you need for simple and clean cable management.

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. 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.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 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. 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 80 Plus efficiency rating has since expanded in recent years to categorize different PSUs from the least to the most efficient.
