The CN model is left out. The page gives a second AC rating of 200-240 Vac, 9 A next to the 100-240 Vac rating and does not say which model it belongs to. The AC input is not a variant field, so the CN model is not stored.

The 80 PLUS list agrees.7Certification listclearesult.com/80plus/sites/80plus/files/manufacturer-certificate/NZXT_PS-2203_1500W_SOCE%207208_Report.pdfRead 15 October 202680 PLUS ID 7208, model PS-2203, 1500W, test date 2023-10-26: Platinum at 115V, 92.52% at 10% load, 94.45% at 20%, 93.89% at 50% and 90.87% at 100%, rated input 100-240V 15-9A. These match NZXT's figures. The certificate prints no serial number (N/A), so the match is by the efficiency figures and input rating. The test date is earlier than the ATX 3.1 launch.
