NZXT C1200 Gold 1200W

One of the strongest power supplies in this batch, the NZXT C1200 Gold is a fully modular, 80 Plus Gold, ATX 3.1 unit with a 12V-2x6 connector, delivering 1200W of headroom for RTX 5090-class builds without HX-tier pricing. It's ideal if your GPU's transient spikes demand the extra ceiling. Mainstream rigs do not need it, since an 850W unit covers a 5070-class build.
