XPG Core Reactor II VE 850W 80 Plus Gold Power Supply Review

Efficiency

Right away we can see great efficiency throughout the load range, never dropping below 90% and often well above that, hitting its peak around 50% load.

PFC (Power Factor Correction)

PFC is very good, the closer to 1.000 the better, with it hitting 0.98 at just 40% and peaking at 80% which is likely where it’ll spend most of its time, and that helps with the efficiency and will reduce heat production.

Voltage Regulation

We like to see these tolerances within 3% and as you can see, the stability of each rail is even better than that, all under 1%, except the 3.3v which was just below that, but still well within tolerance.

As a child still in my 30's (but not for long), I spend my day combining my love of music and movies with a life-long passion for gaming, from arcade classics and retro consoles to the latest high-end PC and console games. So it's no wonder I write about tech and test the latest hardware while I enjoy my hobbies!
