Final Words & Conclusion

Final words & conclusion

The PSU comes with a 10-year guarantee, a massive single rail 12V, a hybrid fan RPM design, and just functioned perfectly in our lab. The component selection and reliability were also excellent. This appears to be a pretty good power supply in general. Perhaps a touch costly, but we'll go over that further at the end.  While a GOLD-certified device may not provide that final ten watts saving in energy efficiency, we must acknowledge the product as a superb mainstream to high-end power supply series. This power supply series' quality, longevity, and efficiency are unquestionable. It specified where it should be and seemed to be in the correct location. The warranty is a proper 10 years. A notable benefit is the entirely modular design, which includes appealing all-black wiring and connectors. When compared to other PSUs in this category, the series' efficiency is spot on gold certification; combined with the modular design, this is an unquestionably appealing PSU series. Looks, acoustics, and quality are all important. As far as the ODM is concerned, this design appears to be of CWT (Channel Well Technology) provenance.

Efficiency

As with any power supply, half the maximum load rating is your point of equilibrium, the sweet spot at which it operates at peak efficiency, which in this case is 92 percent (@230 Volts). As such, the 500 Watt range is a sweet spot. ionly an enthusiast class gaming PC with a dedicated (6900XT / RTC 3080/3090) graphics card would consume around that amount during a lengthy gaming session (I am talking enthusiast-class). You could purchase a more efficient power supply ranging from Bronze to Platinum. It's become a bit of a marketing issue over the years, as differences of a few percent are really all we're talking about here. That is also the difference in percent on your electric bill. We've shown the power discrepancy based on a 50% PSU load against the energy usage below (wall side).

Let's say you game 5 hours per day, 5 days a week for a full year. During gaming, you'll consume 500 Watts (= a fair estimation for an enthusiast-class PC). We assume you pay 23 cents for each kWh of energy. As you can see, from 80plus to Titanium, the difference is eight EUR/USD for thirteen hundred hours of gaming per year. My overall advice is to go with silver or gold; platinum/titanium power supplies often carry a big price premium. I do want to state, though, that efficiency also says something about build quality. Follow your instinct, I'd say. Now, this plot and math is e based on gaming. Of course, if you'd have your PC active 24/7 for mining, you'll want as efficient PSU as possible as coming from 80plus to Titanium you'll save roughly 152 USD/EUR per year (depending on kWh prices).

Stability

Stability-wise, we have very little, if anything, to complain about because voltages remained dead in sync at half load. However, we trust that other reviewers will provide you with some ripple tests, and we have no doubt that the product will come out completely clean. 

 Final words

MSI has a proper offer with the MPG A1000G Power Supply, it offers proper performance versus stability versus quality. It ain expensive either as we spotted this kilowatt unit at under 170 EUR/USD. Combined with a 10-year warranty you just can't complain. However, the biggest worry for MSI will not be the product, but rather the saturated market and in the end, competition. The MSI MPG A1000G delivers really respectable performance, but it is not battling that strong competition. If MSI would have wanted to sidestep the competition and give it a little edge, it would have been nice to see the new PCIe Gen5 type graphics connectors included. Perhaps that's a missed opportunity. We need to consider that these are MSI's first steps into the PSU sector, and thus far, things are going smoothly, unlike its main competitor, Gigabyte.

MSI are building the PSU series with CWT; with a touch of MSI in the design; and that certainly applies to silence, build quality, and gold-rated efficiency. We like the hybrid fan/fan stop mode. The entirely modular design is pleasing to see. For a gamer who spends a few hours a day gaming, you should consider your options; Gold, Platinum, or even Titanium. The price advantage will, however, be significantly greater than the long-term energy savings. On the other hand, the less energy you spend, the better, from an environmental standpoint. With its flat wires, the MSI MPG A1000G can accommodate numerous high-end graphics cards and connect many components or, of course, the new 450W upcoming graphics cards. The MPG A1000G has enough power to satisfy the needs of today's GPUs, and its compact dimensions allow it to fit in any ATX case.
