MSI are definitely pushing into the power supply market this year with a range of new units launched since Christmas. The MPG A1000GS is the second PSU we have reviewed from them, and while it is a good product I have some points I need to go over before wrapping up this review.

Firstly, I feel the omission of a second 6+2Pin PCIe cable is rather strange as it will alienate many AMD GPU owners. The A1000GS has clearly been released to target Nvidia 40 and 50 series owners, which I understand, but potentially alienating AMD users is not a very good public relations exercise. It is also not very clearly explained either online or on the box – you need to be paying attention. This could have been a ‘non issue' by simply including a 12V 2×6 to 2x 6+2 pin PCIe cable.

Secondly, while I am impressed with how quiet this unit performs (even under heavy load) I feel MSI could do with optimising the fan to be more aggressive as the loads increase. I appreciate that targeting an audience which values the lowest possible noise is a good idea, but this unit is not massively efficient by higher 2025 standards and temperatures do suffer a little under heavy load – as reported earlier in the review.

Technically the A1000GS performs pretty well, load regulation is solid and it passed our cross loading test without any issues or concerns. Ripple suppression could be better however, especially when we factor in some of the results lately from competitor products. Not to say the unit will exhibit any ‘real world' issues based on what we documented, but the design clearly could be optimised a little more to improve the results.

Internally I was happy to see CWT paying a lot of attention to the component selection.  The A1000GS is loaded with high quality capacitors and FETs and they have not skimped on the quality of the primary stage components either, adopting a high grade Japanese Rubycon 105c rated capacitor and other Japanese capacitors throughout the secondary stage.

The pricing for this product seems a little on the high side in my opinion. As the last power supply i reviewed was the MSI Ai1600T at £600+, I had to readjust my way of thinking when considering a value proposition. A quick search on Scan UK shows that a lot of 1000W 80 Plus Gold Certified power supplies are available for between £150 and £180 (HERE).

At time of publication you can currently buy the A1000GS on stores such as AWD IT for £184.99 HERE. That is the recommended retail price of the product, so I doubt you will see it for any less unless it is on sale. So while the power supply delivers a decent set of results it is right at the upper level in this price bracket, meaning it really should be delivering something ‘extra special' for the customer. The MSI MPG A1000GS while certainly competent isn't really an exceptional design.

MSI are offering a full 10 year warranty with this power supply, which is very good for an 80 Plus Gold rated unit. Just be aware if you use AMD graphics cards to pay very careful attention to the fact you only get a single 6+2 pin PCIe connector, meaning it is not suitable for a high end AMD graphics card.

Pros:

• Quiet at all times.
• 105c rated Japanese connectors.
• Tight load regulation.
• High build quality.
• Fully modular.
• High quality components inside.
• Fluid dynamic bearing fan.
• Gold certified on both Cybenetics and 80 Plus platforms.

Cons:

• Quite expensive on the market today.
• Fan could be tuned to be more aggressive at higher loads to reduce internal temperatures.
• Only a single 6+2 pin PCIe connector cable, high end AMD gamers should avoid.
• No fan failure protection.

KitGuru says: The MPG A1000GS is a very good power supply well suited to powering Nvidia RTX graphics cards. Load regulation is tight and the overall build quality and choice of internal components is excellent.
