Great power output for even the most demanding setups

Fully modular cables for easy customization and cable management

Quiet fan operation at low to moderate loads

80-plus gold certification for energy efficiency

Generous 10-year warranty for added peace of mind

Not all users are satisfied with the stiffness and bulkiness of the cables

Perpendicular positioning of SATA power cable may not be ideal for some setups

Some users have reported a new electronics smell when the fan turns on during gaming

Verdict

Overall, the Corsair RM850x is a well-built and reliable power supply unit with plenty of power ports for even the biggest GPU/CPU combos. The modular connectors are easy to use and the fan operates silently at low to moderate loads. However, some users have found the cables to be stiff and difficult to manage, and the choice of SATA power cable has been criticized for its perpendicular positioning. Additionally, some users have reported a new electronics smell when the fan turns on during gaming. Despite these minor issues, the RM850x is a solid choice for those in need of a high-quality power supply unit.

[PSU] Seasonic Flagship PRIME 600 Titanium Fanless SSR-600TL 600W 80+ Titanium Full Modular - $157.99 + 6.99 shipping ($239.99 list price - 82.00) Newegg on eBay

No noise whatsoever and easily powers my Ryzen 7 3700x and RTX 3070. Doesn't get hot to the touch too even during heavy load. I resorted to this as I returned the last 3 PSUs I bought due to them being noisy, well I got tired and I thought why not buy a fanless PSU to avoid the noise. The only PSU I tried that is really silent is the Corsair RM850x but I chose this PSU in the end because Seasonic has a better warranty here in my country (Philippines).
