  • Nice PSU
Style: RMe (2025) ATX 3.1, PCIe 5.1 Size: 750 Watts Color: Black
Works great, looks great. Easy to install, and provides more than enough power (according to your own setup of course). Noise is minimal, its not louder than any modern graphics card; you'll hear the GPU before the PSU. It does give a very loud thump when it turns off, but other than that, perfect piece of hardware. Always bought Corsair, never disappointed. Cabling takes a sec, but being able to mix and match allows for excellent cable management. ... show more

Style: RMe (2023) ATX 3.0 & PCIe 5.0 Size: 850 Watts Color: Black
The Corsair power supply is top-notch and delivers exceptional performance, efficiency, and quiet use. One of the biggest things I like about this power supply is its fully modular design. By allowing you to connect only the cables you need, it helps keep your build clean and improves airflow within your case. With an 850W capacity, this is ideal for high-performance builds, including systems with power-hungry GPUs. It's great for gaming pc's and content creation with ease, ensuring consistent and stable power delivery. The RM850e features a quiet 120mm fan that operates near-silently during low and medium loads. Its Zero RPM mode is particularly nice, as it stops the fan entirely during light tasks. ... show more

Arrived packaged properly and with all supporting cables, it was an easy swap into my current PC and has performed great for about a week. Definitely worth the money. Just as quite or if not more than my previous PSU.
