    • A solid power supply for the price.
Color: Black Size: 850W Gold Core Style: Core ATX 3.1
It has a clean, minimal design that looks great in modern builds, and the overall build quality feels much better than what you’d expect in this range. One thing I liked is that it comes with enough cables and connectors for a full high-end setup without needing adapters or compromises. Plenty of support for modern GPUs, multiple drives, and additional components while still keeping cable management pretty clean. Performance-wise, it’s stable, efficient, and quiet under normal use. The 80+ Gold efficiency is a nice bonus, especially for gaming or workstation PCs that stay under load for long periods. Overall, it feels like a very balanced PSU if you want something reliable and good-looking without overspending on ultra-premium models. ... show more

    • Elite quality psu for worry free gaming.
Color: Black Size: 850W Gold Core Style: Core ATX 3.1
Great psu, I have had evga, and corsair psu's in the past. This has a better build quality, better cables (sleeved). And the fan is so quiet i thought it wasn't running or broken, until i used a flash light to see it spinning. I am glad nzxt make such high quality psu's for a great price. I am running a 9950x3d and a 5070. I will update in a year for longevity. ... show more

    • Great Power Supply, No Issues
Color: Black Size: 850W Gold Core Style: Core ATX 3.1
Very quiet, cable management is easy, plug ‘n’ play, compatible with my 9070 XT Reaper and Asus B650E-E Tuf Gaming Wi-Fi AMD AM5 ATX motherboard. The cables feel very nice and durable. The best part about it is not having to worry about having extra cables you don’t need. Definitely invest in a power supply in this range. It’s a very normal sized power supply and will fit fine is a regular build. ... show more
