AI Verdict

This is an 850-watt 80 Plus Gold ATX 3.1 & PCIe 5.1 fully modular power supply with 100% Japanese capacitors and a 150mm fan, designed for new PC builds needing current GPU compatibility.

Situational Fit

This 850-watt 80 Plus Gold power supply is a strong contender for new builds using current-generation GPUs due to its ATX 3.1 and PCIe 5.1 compatibility. The fully modular design and compact 150mm size are practical for cable management and wider case compatibility. However, the lack of existing user reviews means its real-world performance and reliability are unverified.

If you need verified long-term reliability or specific noise profiles, look for PSUs with extensive user feedback and professional reviews already available.

Pros

  • 850 watts provides ample power for high-end GPUs like Nvidia RTX 40/50 Super and AMD GPUs
  • 80 Plus Gold certification means at least 87% efficiency at 20% load, 90% at 50% load, and 87% at 100% load, reducing heat and energy waste
  • ATX 3.1 & PCIe 5.1 readiness supports 200% total power excursion and 300% GPU power excursion, crucial for modern graphics cards
  • 100% Japanese capacitors are used for improved reliability and durability
  • Fully modular cables mean you only connect the cables you need, reducing clutter and improving airflow
  • Zero RPM fan mode keeps the 150mm fan off until the internal temperature reaches 60℃, ensuring quiet operation under light loads

Cons

  • No user reviews are available yet due to the product's future release date (August 13, 2024), so real-world performance and longevity are unconfirmed.
  • Conflicting information exists online regarding fan size (120mm vs. 150mm) and modularity (fully modular vs. non-modular) for models with similar names, which could cause confusion for buyers.
  • The 150mm fan size, while allowing for quiet operation, is larger than some standard 120mm PSU fans, potentially impacting compatibility in extremely compact cases if the PSU itself isn't compact enough (though it's listed as 150mm compact size).

Dimension Scores

Efficiency & Output8/10

The 80 Plus Gold certification guarantees high energy efficiency, and 850 watts with ATX 3.1 & PCIe 5.1 support provides robust output for modern high-end GPUs.

Noise Level7/10

The Zero RPM fan mode ensures silent operation under light loads, with the 150mm FDB fan only activating at 60℃, aiming for low noise even when active.

Build Quality7/10

The inclusion of 100% Japanese capacitors and OVP/OCP/OPP/OTP/UVP/SCP protections suggests a focus on component quality and safety features.

Cable Management8/10

The fully modular design with flat cables significantly reduces clutter and improves airflow, making cable management much easier.

Best For

  • New PC builds featuring Nvidia RTX 40/50 Super or AMD GPUs requiring ATX 3.1 & PCIe 5.1 power connectors
  • Users prioritizing energy efficiency and reduced heat output in their system
  • Builders who want clean cable management with fully modular cables in a compact 150mm PSU footprint
  • Systems where quiet operation under low to moderate loads is a priority due to the Zero RPM fan mode

Not Recommended For

  • Budget builds where 850 watts and Gold efficiency might be overkill
  • Users who need confirmed long-term reliability data from existing user reviews
  • Extremely small form factor cases that might struggle with a 150mm fan or the overall 150mm PSU length

Watch Out For

  • The product's 'Date First Available' is August 13, 2024, meaning there are no actual user reviews or long-term performance reports available yet.
  • Online listings for similarly named Redragon PSUs show conflicting specifications, with some stating a 120mm fan and non-modular design, which could lead to purchasing the wrong variant or expecting different features.
  • While listed as 'compact 150mm size', some cases might still have tight clearances for cable routing with a 150mm length PSU, especially with the included flat cables.

What Buyers Say

As of its 'Date First Available' of August 13, 2024, there are no actual user reviews or hands-on feedback available for the Redragon RGMS-850W PRO 850 Watt Power Supply. Information is based solely on product specifications and marketing materials. There are also conflicting specifications found online for similarly named Redragon PSUs, specifically regarding fan size and modularity, which could be a point of confusion for potential buyers.

“Can't really say much yet since it's not even out, but the specs look good on paper for my new RTX build, hoping it lives up to the ATX 3.1 hype.”

Frequently Asked Questions

Does this PSU come with a 12VHPWR cable for RTX 40 series GPUs?

Yes, the Redragon RGMS-850W PRO is PCIe 5.1 ready and includes a 12VHPWR cable in the package, making it compatible with high-performance NVIDIA 4090/4080/4070Ti graphics cards.

Is the fan always running?

No, it features a Zero RPM Mode fan. The fan only activates when the internal temperature reaches 60℃, remaining in 0 RPM mode for quiet operation under lower loads.

What does '80 Plus Gold' mean?

80 Plus Gold certification indicates that the power supply operates at a minimum of 87% efficiency at 20% and 100% load, and 90% efficiency at 50% load. This means less wasted energy as heat and lower electricity bills.

What are Japanese capacitors?

The PSU is built with 100% Japanese capacitors, which are generally regarded as higher quality components that contribute to better reliability and durability of the power supply.

Will this fit in my PC case?

The power supply has a compact 150mm size, which is designed for better and wider chassis compatibility, leaving more room for cable management.

Buying Guide

When you're looking at a power supply, you're basically picking the heart of your PC. You need enough wattage to feed all your components, especially your graphics card. Efficiency ratings like 80 Plus Gold tell you how much power is wasted as heat, so higher is better for your electricity bill and case temperatures. Also, check for modern connectors like ATX 3.1 and PCIe 5.1 if you're getting a new, powerful GPU.

wattage

This is the total power your PSU can deliver. Think of it like the horsepower of a car; if your components (especially the CPU and GPU) demand more than the PSU can provide, your system won't run stably or might not even turn on.

80 Plus Gold rating

This is an efficiency standard. A Gold rating means less electricity is converted into heat and more goes to your components, saving you money on your power bill and keeping your PC cooler than lower-rated PSUs.

ATX 3.1 & PCIe 5.1

These are the latest power standards, especially important for new, high-power graphics cards. They ensure the PSU can handle sudden power spikes from your GPU without issues, preventing crashes and ensuring stable performance.

Fully Modular

This means you only plug in the cables you actually need for your components. It makes building your PC much cleaner, improves airflow inside your case, and makes troubleshooting easier compared to non-modular PSUs with fixed cables.

Alternatives

If this PSU doesn't fit, look for models with different wattage (e.g., 750W or 1000W), higher efficiency ratings (Platinum or Titanium), or a smaller physical footprint if you have a very compact case.
