NZXT's recent C-series PSUs have made for some solid choices for price to performance, offering beefy power outage for a reasonable prices, as well as excellent efficiency ratings, too.

1000W of power is enough for powering even some of the beefiest of systems. It's above the recommended wattage for most 'standard' RTX 4090 offerings, apart from some overclocked models which have a 1000W minimum, while everything underneath that from both Nvidia and AMD will be more than adequate. For the RX 7900 XTX, the recommendation is a bare minimum of 750W, so 1000W gives you more than enough headroom. If it's also any further proof, this C1000 PSU is top-tier rated on the Cultists PSU Tier List (formerly of LTT Forums).
