What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
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.
Thermaltake Toughpower GF3 850W
Based on one whitelisted lab test (Tom's Hardware). Aris Mpitziopoulos rates the GF3 850W a well-built early ATX 3.0/PCIe 5.0 unit on a CWT CSZ platform, quiet and efficient at light loads, but with sub-88% normal-load efficiency, sub-16ms PWR_OK hold-up, high-load noise exceeding 50 dBA, and overall performance trailing the Corsair RM850x and EVGA 850 G7. (1 sourced review, 1 lab-tested.)
Praised: Good build quality on a high-quality CWT CSZ platform; One of the first 850W units with ATX 3.0, PCIe 5.0 and a 12VHPWR connector; Quiet under normal operating temperatures (average noise below 30 dBA).
Flagged: Overall/normal-load efficiency is low, below the 88% it should hit; PWR_OK signal hold-up time falls below the 16ms ATX minimum; Noisy under high load at high temps, exceeding 50 dBA.
