Load regulation is within 1% on all primary rails, but 3.3V, where it is a little higher (1.1%).

Ripple suppression is good, but not groundbreaking, on all rails.

Thanks Aris. Been waiting for this.
Got this psu on prime day discounted w/ a $50 rebate based on your ATX 3.0 tier list. Was hesitant to jump the gun since there was no cybernetics report or in-depth reviews on the 850W at the time.
Relieved to see your positive endorsement of the OEM. 😅
Thanks. How does it compare to Cooler Master V850 Gold V2? can we please have a review?

The V850i belongs to a higher category.
