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.
MSI MPG A1000G PCIE5
Only one whitelisted tester (Tom's Hardware) lab-tested this exact model. It praised the unit's exceptional power quality, tight 12V regulation and low operating temperatures, while flagging an aggressive fan that turns loud above 500W, slack OCP/OPP thresholds, a high-load efficiency drop, and a steep price. (1 sourced review, 1 lab-tested.)
Praised: Exceptional power quality: max 22 mV ripple on 12V and tight <0.8% 12V regulation; Excellent build quality with all-Japanese capacitors and future-proof ATX 3.0 support; Runs cool at all loads with high low-load efficiency.
Flagged: Aggressive fan profile becomes clearly audible above ~500W and hits max speed by 800W; Slack OCP/OPP protections set too high (>140% current, >1300W before shutdown); Sharp efficiency drop at high loads, keeping it to 80Plus Gold rather than Platinum.
