Excellent PSU — Quiet, Stable, and Great Value
I bought the MSI MPG A1000GS PCIe 5.0 Fully Modular 1000W PSU and it has been a great upgrade for my system. Power Compatibility: I use an RTX 2080 Ti, which requires two 8-pin PCIe connectors. The PSU only includes one PCIe cable with a single 8-pin, so at first I thought I’d have a problem powering my GPU. Fortunately, MSI’s online portal offers a free 12VHPWR (12-pin) to dual 8-pin cable, and that cable works perfectly. No instability, no crashes — power delivery has been completely solid. The unit feels very well-built, the modular cables plug in securely, and the PSU runs extremely quiet. Even during gaming sessions, the fan noise is barely noticeable. Even though it only ships with one PCIe cable, the free portal cable option solves the issue for older GPUs like the 2080 Ti. The PSU itself is rock-solid: quiet, efficient (80+ Gold), and totally stable under load. Highly recommended if you want a clean, future-proof power supply with great value.

Powerful and silent, a real good choice!
The MPG A850GS provides enough power for the 9800X30 and RX9070 XT build that I have, with some room to grow. Overall I really like the size of the power supply it's been a while since I have purchased a PC power supply and was kind of surprised by how compact the unit is. It's fully modular and provides more than enough cables for nearly any build. The unit is quiet even with the fan on, it also offers a silent operation mode if you need that. So far I do not detect any type of coil whine or anything that would impede it's operation. I am extremely happy with how this unit performs and functions. It was super easy to install and it feels quality built. The durability should last for years. The warranty is top notch too!

Reliable, quiet, and powerful. Fully modular with updated support.
Solid, high-quality 1000W PSU. Fully modular cables made installation easy and clean, and the unit runs very quiet even under load. ATX 3.1 / PCIe 5 ready, and still powerful enough for my 3070 (with a free cable from MSI). Feels well-built and stable... excellent value for the price.

Outstanding PSU
Phenomenal PSU, the native 12v power connector was the perfect size and length for the 5080 I paired the system with. It's silent, even with the zero fan mode off. Another outstanding MSI product that will support any modern PC setup with full functionality. The price for performance is also just about unbeatable. You'll be hard pressed to find anything better for the money.

NICE PSU!!!
**What is your favorite aspect of the product and how did it improve your user experience?** My favorite aspect of the MSI MPG A1000GS is its fully modular design combined with exceptional power delivery. Being able to connect only the cables I needed kept my build clean and greatly improved airflow within the case. The stable 80+ Gold efficiency also ensures the system runs cooler and more quietly, which enhances both performance and reliability during long gaming sessions. **Why did you choose this product over another?** I chose the MSI MPG A1000GS because it offers a strong mix of high wattage, efficiency, and future-ready PCIe 5.0 support at a competitive price point. Compared to other 1000W units, it stood out for its solid brand reputation, fully modular cabling, and support for newer graphics cards without the need for adapters, which simplified the build process. **Does the product fulfill your needs? Does it deliver beyond your expectations?** Yes, this power supply fully meets my needs for a high-performance gaming rig and then some. It delivers consistent, stable power even under load, and the efficiency rating helps keep energy waste and heat generation down. It even exceeded my expectations with surprisingly quiet operation, even with a fully loaded system. **What do you feel are the strengths and weaknesses of the product?** **Strengths:** The MSI MPG A1000GS offers excellent efficiency (80+ Gold), fully modular cabling for tidy builds, and strong support for PCIe 5.0 components. It provides stable power delivery, quiet operation, and reliable performance that’s ideal for high-end gaming or workstation systems. **Weaknesses:** It’s on the pricier side compared to some other 1000W units, and the included dual 12V-2x6 cables may require adapting for certain GPUs if you’re running very high-end cards. Additionally, while 80+ Gold is efficient, some users targeting ultimate power savings might prefer a Platinum-rated unit.

Great Device!
The MPG A1000GS PCIE5 has been an outstanding anchor for my performance-heavy system. What immediately impressed me is how quietly it runs while still delivering steady, dependable power during demanding workloads. I went with this PSU specifically for its native PCIe 5.0 and ATX 3.0 support, so I’m fully prepared for upcoming GPU generations without relying on extra adapters. The fully modular layout made routing cables clean and simple, and the 80 PLUS Gold rating gives me confidence that it’s operating efficiently. Between its compact size, solid construction, and overall reliability, it exceeded what I was looking for. Anyone putting together a high-end build and wanting long-term stability would be well served with this unit.

Excellent Future-Proof PSU
The MSI MPG A1000GS is one of the best power supplies I’ve used. It’s compact for a 1000W unit, fully modular, and very easy to build with. The cables are flexible and include the new 12VHPWR connector, so it works perfectly with modern GPUs like the RTX 5000 series without adapters. Performance has been rock solid—voltages stay stable under load, and the Zero RPM fan mode keeps it silent during light use. When gaming or stress testing, the fan spins up but never gets overly loud. With its 80 Plus Gold efficiency and high-quality Japanese capacitors, it feels reliable and future-ready. Yes, it’s a little more expensive than older models, but the build quality, quiet operation, and ATX 3.1 support make it worth it. If you’re building a high-end rig and want something that will last for years, this PSU is an excellent choice.
