## What reviewers say

**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.)

**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.
