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

A glance at the light-load table is always useful, as the PSU typically operates 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 during the AC-to-DC conversion. Lower ripple is highly preferable because it ensures a cleaner, more stable DC output, thereby reducing noise and potential interference in sensitive electronics, thereby improving performance and extending the lifespan of components. High ripple can cause instability, overheating, or damage to connected devices.

Ripple suppression is good at 12V and 5V and decent at 3.3V. It could be a bit better at 5VSB, but it doesn’t matter much as long as it is below the corresponding limit. I remember back in the day when Seasonic platforms used to be among the best in ripple suppression, but the competition has grown way stronger now.
Will you doing a review for the YS1000W version as well?
Hello Aris, i saw something strange in my country psu market, The Gamdias Helios P2 1300g & 1000g has cybenetics gold certification in the units sold in my country, but there’s nothing in cybenetics database about this brand
I have to send another note to Gamdias, as it seems, because they keep on using Cybenetics ratings without having them! Thank you for letting us know!
I hope they sent units for real certification in cybenetics… I also hope Redragon and risemode send units for certification. I don’t buy psu without cybenetics certification
Look it . I saw it, I thought it strange

Hello Aris, it seems that your review of the NZXT C1200 and C1000 is not accurate. The specifications on the Cybenetics site for the NZXT C1000 are listed here https://www.cybenetics.com/evaluations/psus/2448/, but on HW Busters it looks different; that is the NZXT C1200 https://hwbusters.com/psus/nzxt-c1200-atx-v3-1-psu-review/. I hope you can revise it soon. I am also waiting for news on several pending Cybenetics certification, such as the MSI A1250GS and some Gamemax Lioncore PSUs.
Hi Alex, what is wrong? It is typical of me to do some typos in the specs, but please point out what is different to save me some time.
because on your review on hwbusters the part analysis it’s should be NZXT C1000, just rechecked that NZXT C1000 should using this : https://hwbusters.com/psus/nzxt-c1000-atx-v3-1-psu-review/3/

based on this data NZXT C1000 on the cybenetics web should use this data, and that NZXT C1000 parts description data on Cybenetics web should belong to NZXT C1200
it seems your just misconfigured the parts description NZXT C1000 on cybenetics and using NZXT C1200 data, i see that you also don’t put the parts description of NZXT C1200 on cybenetics web, maybe you can revised up later
thank you, fixed it!
Is the review for the Hxi 1500 further delayed? Could you give me a rough estimate of when it might be ready?
into next week most likely.
So until Friday?
