What reviewers say about the 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.

Tested by Tom's Hardware
Consistently 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
Commonly 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
- Pricey for its class (~$180 street)
Where reviewers disagree Only one whitelisted source, so no cross-outlet comparison is possible. The single reviewer is internally split: it rewards the unit's cool, low-temperature operation while criticizing the very aggressive fan profile that produces those low temperatures.

Avg efficiency (20-100% load, 230 VAC): 91.0% · Avg efficiency (20-100% load, 115 VAC): 90.1% · Max ripple, 12V line: 22 mV · Max ripple, 3.3V line: 10 mV · Max ripple, 5V line: 12 mV · 12V line regulation (20-100% load): <0.8% · OCP trip point: >140% rated current · OPP trip point: >1300 W · Thermal losses at max load: >125 W · Avg efficiency degradation (hot, ~45C ambient): 0.65%
It delivers exceptional power quality, with minimal voltage fluctuations across the entire load range.
The controller had the fan running at maximum speed by the time the load was 800 Watts, making the MPG A1000G PCIE5 annoyingly loud.
The current street price of $180 is the Achille's heel of this unit
