Review: Top product no worry purchase - I recently purchased the CORSAIR RM850x Fully Modular Low-Noise ATX Power Supply as a critical component for a new PC build, specifically to pair with a high-end motherboard. While it wasn't the cheapest option on the market, I firmly believe that the PSU is the heart of a computer, and cutting corners here is a risk not worth taking. This unit has proven to be an excellent investment, offering ATX 3.1 compliance and PCIe 5.1 support for modern systems. The build quality is immediately apparent. The unit feels solid and well-constructed, and the included components are top-notch. It came with a comprehensive set of high-quality, fully modular cables, which made cable management an absolute breeze and resulted in a much cleaner build with better airflow. The native 12V-2x6 connector was a great bonus, making the build process even smoother. A great PSU isn't just about providing power; it's about providing clean, stable power. This unit, with its Cybenetics Gold Efficiency rating, does exactly that, ensuring my motherboard and other expensive components are protected from fluctuations and delivering consistent performance, especially during demanding tasks. The low-noise operation is a fantastic feature, keeping my system quiet even under load. The peace of mind that comes with knowing my system is being powered reliably is well worth the price. Overall, I am extremely impressed with this PSU. It's a premium product that lives up to its reputation and is an essential partner for any serious PC build. Pros: Exceptional build quality from a trusted brand. Fully modular cables for superior cable management and aesthetics. Provides clean, stable power with Cybenetics Gold Efficiency, protecting expensive components. Low-noise operation keeps the system quiet. ATX 3.1 and PCIe 5.1 compliant for modern hardware. Comprehensive set of cables included for all build needs. Excellent value considering the long-term protection and reliability it offers. Cons: None, if you understand that a quality PSU is a worthwhile investment. Five stars. Don't skimp on your PSU. This one is highly recommended.
Review: Underrated and Performs Amazingly - I initially returned this GameMax 850W Rampage Power Supply thinking it was the cause of my PC issue, but after further troubleshooting, I realized the problem was actually with my graphics card—not the PSU. In hindsight, this PSU was actually amazing, and I regret returning it. Why It’s a Great PSU ✔ Reliable Power Delivery – Handles demanding setups smoothly with real 850W power. ✔ Fully Modular Design – Makes cable management much easier. ✔ Japanese Capacitors – Ensures longevity and stability. ✔ Good Efficiency (80 Plus Bronze, 88%) – Performs efficiently for a mid-tier PSU. ✔ Quiet 14cm Cooling Fan – Keeps noise levels low even under load. Why It’s Underrated This PSU doesn’t get enough credit—it performs just as well as some higher-priced alternatives. I initially doubted it, but after testing, I found it to be solid, stable, and efficient. Final Verdict If you need a reliable, fully modular, and efficient 850W PSU, the GameMax Rampage is a great choice. My return was unnecessary since my issue was with my GPU, and I’d definitely recommend this PSU to anyone looking for a budget-friendly but powerful option. Rating: ⭐⭐⭐⭐⭐ (5/5) – Excellent PSU, wrongly blamed for my PC issue!

### ⭐⭐⭐⭐ Good for the money. Can use nicer cable!
*by A***A on 30 March 2025*

Well, it works out of the box. As expected. It's 60 pounds for a fully modular PSU, so one would expect quality to be cut somewhere. I think it's the cables. A more expensive brand would have some sort of sleeving to make it look nicer. Not this one. It's a big discount over the premium brands, but it's very good price for what it is. I bought it for a budget rebuild. I won't buy it for my main PC when I'm due an upgrade.
