Review: Excellent power supply for new build. - Perfect this time. Building two pc's and this is running 7800x3d, rx7800xt, 32gb ram, msi tomahawk x870. No issues power stays under 50% threshold unless gaming but never good above ~65% Only issue is I ordered two, first one that was white was used and didn't not have the adjustable fan. But the black one came sealed everything in bags Review: Quality - I've built my own desktop computer for the last thirty years and have used different types of Power Supplies. Modular is nice because it keeps down the clutter in the case which helps with better air flow. This specific RM850x is clearly labeled and the cords are type IV which is nice. Unlike so many of the lesser watt power supplies, it came with 3 PCle cords. It is low-noise and runs cool. Works great. ## Features - Fully Modular: Only connect the cables your system needs, making clean and tidy builds easier. - 135mm Magnetic Levitation Fan: Utilizes a magnetic levitation bearing and custom engineered rotors for high performance, low noise, and superior reliability. - EPS12V Connector: For wide compatibility with modern graphics cards and motherboards. - 100% All Japanese 105°C Capacitors: Premium internal components ensure unwavering power delivery and long-term reliability. - Modern Standby Compatible: Extremely fast wake-from-sleep times and better low-load efficiency. - 80 PLUS Gold Certified: High efficiency operation for lower power consumption, less noise, and cooler temperatures. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08R5JPTMZ | | Best Sellers Rank | #2 in Computer Power Supplies | | Brand | Corsair | | Compatible Devices | Personal Computer | | Connector Type | ATX | | Connector Type Used on Cable | ATX | | Cooling Method | Air | | Customer Reviews | 4.8 out of 5 stars 5,704 Reviews | | Fan Size | 135 Millimeters | | Form Factor | ATX | | Item Dimensions | 6.3 x 5.91 x 3.39 inches | | Item Weight | 1.7 Kilograms | | Manufacturer | Corsair | | Maximum Input Voltage | 240 Volts | | Mfr Part Number | CP-9020200-NA | | Minimum Input Voltage | 100 Volts | | Model Name | RM850X | | Model Number | CP-9020200-NA | | Number of Fans | 1 | | Output Wattage | 850 Watts | | Power Supply Design | Full Modular | | System Bus Connector Type | EPS | | UPC | 840006604839 | | Unit Count | 1.0 Count | | Warranty Description | 10 year manufacturer | | Wattage | 850 watts | ## Product Details - **Brand:** Corsair - **Compatible Devices:** Personal Computer - **Connector Type:** ATX - **Cooling Method:** Air - **Form Factor:** ATX - **Item Weight:** 1.7 Kilograms - **Item dimensions L x W x H:** 6.3 x 5.91 x 3.39 inches - **Model Name:** RM850X - **Output Wattage:** 850 - **Wattage:** 850 watts ## Images ![CORSAIR RM850x Fully Modular ATX Power Supply - 80 Plus Gold - Low-Noise Fan - Zero RPM - Black - Image 1](https://m.media-amazon.com/images/I/81k55rfk1iL.jpg) ![CORSAIR RM850x Fully Modular ATX Power Supply - 80 Plus Gold - Low-Noise Fan - Zero RPM - Black - Image 2](https://m.media-amazon.com/images/I/81PPMawxblS.jpg) ![CORSAIR RM850x Fully Modular ATX Power Supply - 80 Plus Gold - Low-Noise Fan - Zero RPM - Black - Image 3](https://m.media-amazon.com/images/I/81DF6QzgKcS.jpg) ![CORSAIR RM850x Fully Modular ATX Power Supply - 80 Plus Gold - Low-Noise Fan - Zero RPM - Black - Image 4](https://m.media-amazon.com/images/I/81JRGxD4BJL.jpg) ![CORSAIR RM850x Fully Modular ATX Power Supply - 80 Plus Gold - Low-Noise Fan - Zero RPM - Black - Image 5](https://m.media-amazon.com/images/I/81fgZ5rL-fL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Does this come with cables, or not?** A: Yes, our PSUs always include cables.
