Load Regulation
It measures the stability of the output voltage when the load connected to the power supply varies.

A glance at the light loads table is always useful, as the PSU will typically operate at light loads.
Ripple Suppression
Ripple in power supplies refers to the small, unwanted AC voltage fluctuations superimposed on the DC output. It occurs due to imperfect filtering of the AC-to-DC conversion process. Lower ripple is highly preferable because it ensures a cleaner, more stable DC output, thereby reducing noise and potential interference in sensitive electronics, which improves performance and extends the lifespan of components. High ripple can cause instability, overheating, or damage to connected devices.

Ripple suppression is good overall.

i was able to get this thermalright TR KG850 on sale for $36, i was wondering how bad it would be if i used a 300W GPU (9070 XT hellhound OC) since the cables are only 18AWG.
PS: and I’d like to humbly request that someone could test this PSU as I havent found anyone. it came out in 2025, and has a 5 year warranty.
even more interestingly a better PSU, TR-AG850 has a 10 year warranty which may be a competitor at the high end of PSUs.
Unfortunately, I cannot get my hands on TR PSUs. With the first chance, sure I will test them!
thanks! I’ve just emailed Thermalright recommending them to contact you, not sure if that’s how it’s supposed to work but hopefully they follow up.
Thx aris for a review, btw do you have any Cybenetics updates for XPG Pymcore series can’t wait to see the internals ?
No yet, sorry.
