ATX 3.1 Compliant

ATX 3.1 powers high-performance components with stable delivery and improved efficiency.

A line graph titled Efficiency compares energy efficiency of NZXT C850 Gold and 80 PLUS Gold Standard @115V across load percentages. The NZXT C850 Gold peaks at 50% load, showing higher efficiency than the standard.

Certified for High Efficiency & Low Noise

Line graph titled “Noise” shows dBA increasing with percent loading. Noise stays near zero from 0% to 50% loading, then rises sharply, reaching about 30 dBA at 100% loading.

Silence is Golden

135mm FDB fan with Zero Fan Mode stops spinning under 50% load for total silence.

    Altes System, neues Netzteil

    Bei meinem alten ThinkCentre M92 war das Netzteil ausgefallen. Es ist ein ziemlich alter PC. Nichtsdestoweniger passt das NZXT - Netzteil perfekt - und funktionierte auf Anhieb. Insgesamt macht das Netzteil einen hochwertigen Eindruck, hat anscheinend eingebaute Sicherheits/Schutzschalter und ist im normal-Betrieb nicht zu hören. Perfekt ist das Kabelmanagement - wie gesagt: Auch passend für alte PCs - mit alten / oder sonderbaren ATX-Anschlüssen. Für den Anschluss ans Mainboard brauche ich zwar nach wie vor den Lenovo/ThinkCentre-Adapter - aber das liegt nicht an NZXT, sondern an der proprietären Bauform des Lenovo-Mainboards. Demnächst wird ein aktuelles Board mit neuer IntelCPU angeschafft - Das Netzteil ist optimal darauf vorbereitet. Insofern alles perfekt. Ich wollte diesmal beim Netzteil keinerlei Kompromisse eingehen und wurde belohnt. Der etwas höhere Preis macht sich bezahlt. Es gibt nicht den geringsten Grund zur Klage. Ich kann das Produkt ohne wenn und aber weiterempfehlen. Bestellt über Alternate.de . Lieferschwierigkeiten aufgrund von Trump-Mania. Sonst aber alles Okay.
