How they stack up

ASUS ROG Strix 850G Aura

The ASUS ROG Strix 850G Aura offers a sturdy build and 135mm fan, but its larger dimensions make it incompatible with many cases, unlike the more compact Seasonic Focus GX-850. It's less efficient than the EVGA SuperNOVA 850 G7 and doesn't match the be quiet! Dark Power Pro 12 850W in noise control, though it provides better aesthetic appeal and more cable management options.

Seasonic Focus GX-850

The Seasonic Focus GX-850 is more compact than the Corsair RM850x but suffers from excessive fan noise under light loads, unlike the Corsair's fluid dynamic bearing fan. It matches the EVGA SuperNOVA 850 G7 in 10-year warranty and efficiency, but lacks the latter's Japanese capacitors and superior fan control features.
