It has already been confirmed in a previous discussion that MSI MAG AxxxGL PSUs come with a 5-year warranty. For reference, the reputable review of the A850GL PSU is available here: https://hwbusters.com/psus/msi-mag-a850g...review/11/.
Additionally, the official MSI specifications page does not mention the warranty duration for their MAG AxxxGL series. This situation isn't new; MSI has previously made some adjustments to PSU warranty policies.
The concern about PSU warranty length stems from the importance of reliability. The warranty period reflects how long the manufacturer expects the product to perform reliably.
In summary:
- Up to 2 years: low reliability
- 3 years: moderate reliability (compared to some brands)
- 5 years: average reliability (e.g., Be Quiet!, Straight Power, Seasonic models)
- 7 years: good reliability (e.g., Seasonic Core, Corsair models)
- 10 years: excellent reliability (e.g., Seasonic Focus, Corsair models)
- 12 years and beyond: very reliable
Given current standards, it's generally recommended to opt for a PSU with at least a 10-year warranty. A 7-year warranty might be acceptable if budget allows, but 10 years is the safer choice.
~13 years ago, the typical expectation was 3-5 years of warranty (e.g., Seasonic S12II-520 with 3 years or Seasonic M12II-850 EVO with 5 years). Back then, a 7-year warranty was considered the best option, such as the Seasonic X-series. Today, the norm is shifting toward longer warranties, around 10 years.
This applies whether you're considering brand reputation or personal risk. If a PSU has only a 5-year warranty, you'd be out of coverage after about three years, leaving you without support.
As I mentioned earlier, I currently own two Seasonic PRIME TX-650 units and one Seasonic Focus PX-550. My oldest PRIME unit is 8 years old (purchased in Q3 2016), and with a 12-year warranty, it still has four years of coverage. Under normal use (~15 hours daily), the PSU has performed well without any issues over the past eight years.
Seasonic PSUs are known for their reliability and durability. The S12II series, introduced in 2010, is highly regarded for its longevity—often lasting well beyond the warranty period. I’ve seen units still functioning properly 5 years after purchase. Even my Seasonic S12II-520, which I retired, remains in good condition.
The same applies to M12II-850 EVO models; I retired that one too.
However, not all brands are perfect. Models like A12, B12, G12, and S12III aren’t recommended, especially the S12III, which is made by RSY rather than Seasonic. The Seasonic Focus, Vertex, and PRIME lines are solid choices. Core-series units are only practical when availability or budget allows for the Focus line.
Of course, you don’t have to stick with Seasonic products. There are excellent alternatives, such as Corsair RMi/RMx and Super Flower Leadex series.
Other listings describe the MSI MAG A750GL as a fully modular gaming power supply with 80 Plus Gold certification, delivering 750W at 12VHPWR. It features a compact design suitable for ATX systems and comes with a 10-year warranty.
Upgrade the RAM to 32GB.
Choose a new PC case with a mesh front design to address overheating issues.
Your existing case has a closed front, which restricts airflow significantly.
Replace the power supply unit; the RTX 3070 requires at least 650W, while your current PSU provides only 540W.
