Overview

Progettati per offrire le massime prestazioni con il minimo rumore, gli alimentatori NZXT C Series Gold ATX 3.1 sono pronti a soddisfare le esigenze di GPU e CPU di fascia alta.

Conformi allo standard ATX 3.1 per alimentare componenti PC ad alte prestazioni con stabilità, efficienza e resistenza ai picchi di potenza.
Il connettore 12V-2x6 resistente e a prova di calore eroga fino a 600 watt alle schede grafiche NVIDIA® GeForce RTX™ Serie 50.
La ventola da 135mm con cuscinetto a fluidodinamica e modalità Zero Fan è completamente silenziosa con un carico inferiore al 50%.
I condensatori giapponesi premium al 100% migliorano il tempo di mantenimento e riducono al minimo il ripple, garantendo un'erogazione di energia affidabile e stabile.
Il design completamente modulare consente di collegare solo i cavi essenziali, riducendo il disordine per un migliore flusso d'aria e un assemblaggio più ordinato.
Il formato compatto libera spazio prezioso per la gestione dei cavi e per un maggiore flusso d'aria nel case.
Grazie alla costruzione di alta qualità e ai rigorosi test di prodotto, gli alimentatori NZXT sono coperti da una garanzia di 10 anni.

This is the second c850 I bought and it works perfectly out of the box. No problems, love the look.
I bought this for a second pc in my room. The cables have great quality and look premium even without extenders. My first c850 has also never had any issues since I bought it in January

Works as described.
Picked up from Best Buy for $119 3-14-2026. Very well built and comes with a purple NZXT bag for all the cables to be stored in. Zero Fan button needs to be pushed in for that function to work (button in, fan off). If temp comes up, fan will automatically turn on - Zero Fan function works great - Very Quiet. This C850 Gold ATX 3.1 unit replaced our 2017 ABS MJ1100-M 80 Gold, not because it failed, but because we upgraded our GPU to the RTX5080 OC (360watt) and needed the 12v-2x6 connector. NZXT PSU fit into our existing case leaving more room than my old PSU, cables are slim and modular (clean look).

Hi Robert,

Thank you for the detailed review! We're thrilled to hear that the C850 Gold ATX 3.1 is working perfectly for your RTX 5080 OC upgrade. It's great to know you're enjoying the Zero Fan function and finding it nice and quiet during operation.

We're also glad the modular cables and compact design are giving you that clean look and extra room in your case. The purple cable bag is definitely a nice touch for keeping everything organized!

Thanks for choosing NZXT for your PSU upgrade and we appreciate the honest 5-star review!

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.
