Load regulation is within 1% on all major rails, so it is tight enough.

Ripple suppression is decent on all rails but 3.3V, where it is mediocre, especially at 115V.

Please help! Is the Kyber 850w worth it for $80usd? Bought it the other day, confusing it for the Core Reactor II. I’m on a tight budget but I hope it lasts. If not, I have to save up to get a more expensive one.
It is a decent PSU, yes. The Core Reactor II 850W is typically above 100$ as I remember.
I am unsure if many users will opt to pay 110 dollars for a native-cables-only PSU in 2024, given that with 10-15 dollars more, they can get a fully modular ATX v3.x compliant (e.g., the Thermaltake GF3 A3 850).
On page 11, I think there’s a typo in the thermaltake model’s name (GF A3 vs GF3 A3)
