Review: ATX and CPU cables too rigid. - Good PSU but the cables bundled could be better. The ATX and CPU cables are so rigid and have large unbendable sections where insulation overlaps, that I can not use them in my micro case (Silverstone PS15). Had to order another cable set with flexible cables. Review: Still not sure - I bought this to conserve powr and support my NVIDIA card in my DELL T1700. This PSU model is a ZERO fan noise buy design until it calls for fan to run. I've maxxed the computer 3 times doing video edit and CAD 3d rendering for several hours and the PSU fan never started. 2 case fans, CPU fan and video card fan all ran full speed to during those exercises. There's no way to override the PSU configuration to test the fan. PSU is working I guess but as a passive power supply. ## Features - Fully modular, so you only connect the cables that your system needs. - A 135mm ML fan utilizes a magnetic levitation bearing and custom engineered rotors for high performance, low noise, and superior reliability. - EPS12V connector for compatibility with modern graphics cards and motherboards. - 100% Industrial-grade, 105°C rated Japanese capacitors ensure unwavering power and reliability. - Supports Modern Standby sleep mode for extremely fast wake-from-sleep times and better low-load efficiency. - Zero RPM fan mode for near-silent operation at low to medium loads. - Resonant LLC topology with DC-to-DC conversion provides clean, consistent power, reduces coil whine for quieter operation, and enables use of more energy efficient sleep states. - Ten-year warranty for complete peace of mind. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08R4WJR15 | | Best Sellers Rank | #8 in Computer Power Supplies | | Brand | Corsair | | Compatible Devices | Personal Computer | | Connector Type | EPS | | Connector Type Used on Cable | EPS | | Cooling Method | Air | | Customer Reviews | 4.1 out of 5 stars 21 Reviews | | Fan Size | 13.5 centimeters | | Form Factor | ATX | | Item Dimensions | 6.3 x 5.91 x 3.39 inches | | Item Weight | 1.5 kg | | Manufacturer | Corsair | | Maximum Input Voltage | 127 volts_of_alternating_current | | Mfr Part Number | CP-9020197-NA | | Minimum Input Voltage | 115 volts | | Model Name | RM550X | | Model Number | CP-9020197-NA | | Number of Fans | 1 | | Number of Items | 1 | | Output Wattage | 550 watts | | Power Supply Design | Full Modular | | System Bus Connector Type | EPS | | UPC | 840006603818 | | Warranty Description | 10 year manufacturer | | Wattage | 550 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 RM550x Fully Modular ATX Power Supply - 80 Plus Gold - Low-Noise Fan - Zero RPM - Black - Image 1](https://m.media-amazon.com/images/I/71dUkbyaq7S.jpg) ![CORSAIR RM550x Fully Modular ATX Power Supply - 80 Plus Gold - Low-Noise Fan - Zero RPM - Black - Image 2](https://m.media-amazon.com/images/I/8116DCX3ffS.jpg) ![CORSAIR RM550x Fully Modular ATX Power Supply - 80 Plus Gold - Low-Noise Fan - Zero RPM - Black - Image 3](https://m.media-amazon.com/images/I/81fYoTw7tTS.jpg) ![CORSAIR RM550x Fully Modular ATX Power Supply - 80 Plus Gold - Low-Noise Fan - Zero RPM - Black - Image 4](https://m.media-amazon.com/images/I/81kxOsvzMPL.jpg) ![CORSAIR RM550x Fully Modular ATX Power Supply - 80 Plus Gold - Low-Noise Fan - Zero RPM - Black - Image 5](https://m.media-amazon.com/images/I/81bLBzC80DL.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.

The ATX and CPU cables are so rigid and have large unbendable sections where insulation overlaps, that I can not use them in my micro case (Silverstone PS15). Had to order another cable set with flexible cables. ### ⭐⭐ Still not sure *by L***E on May 30, 2022* I bought this to conserve powr and support my NVIDIA card in my DELL T1700. This PSU model is a ZERO fan noise buy design until it calls for fan to run. I've maxxed the computer 3 times doing video edit and CAD 3d rendering for several hours and the PSU fan never started. 2 case fans, CPU fan and video card fan all ran full speed to during those exercises. There's no way to override the PSU configuration to test the fan. PSU is working I guess but as a passive power supply. ### ⭐ Bought New Came Used *by B***N on November 23, 2022* I bought this psu new and when it was delivered it came in a poly bag. The psu box had visible damage and had no plastic seal. I could feel and hear the psu sliding around in the box, and when I opened it up the psu had no foam protecting it, there were scuff marks all over the thing. Also, the cables were terribly wrapped with that black wire twisty thing. ## Frequently Bought Together - CORSAIR RM850x Fully Modular ATX Power Supply - 80 PLUS Gold - Low-Noise Fan - Zero RPM - Black - SAMSUNG 990 PRO SSD NVMe M.2 PCIe Gen4, M.2 2280 Internal Solid State Hard Drive, Seq.
