EVGA SuperNOVA 1000 G7
One whitelisted lab review (Tom's Hardware, by Aris Mpitziopoulos) covers this exact model. Across its six-page bench test, the reviewer rates the 1000 G7 among the best 1000W units and the smallest 1000W ATX PSU, with high measured efficiency (Cybenetics Platinum, peaking above 92% at mid load), tight load regulation and excellent 12V transient response, but noisier at full load than the Corsair RM1000x. (1 sourced review, 1 lab-tested.)
Praised: Top-tier overall performance and high measured efficiency (Cybenetics Platinum), peaking above 92% at mid load; Smallest 1000W ATX PSU with compact 130mm depth and high build quality (Rubycon/Chemi-Con caps, FDB fan); Tight load regulation and excellent 12V transient response.
Flagged: Higher noise output than the Corsair RM1000x due to the small fan and overpopulated PCB (47.5 dB(A) at full load); High inrush currents at both tested input voltages; No PCIe 5.0 / ATX 3.0 (12+4 pin) connectors.
