Pros

  • 80 Plus Gold Certification delivers 90% efficiency at 50% load, reducing heat and power consumption.
  • ATX 3.1 and PCIe 5.1 readiness supports 200% total power excursion and 300% GPU power excursion for NVIDIA 4090/4080/4070Ti graphics cards.
  • Built with 100% Japanese Capacitors for enhanced stability and durability.
  • Zero RPM Mode fan keeps the fan off until the temperature reaches 60℃, aiming for silent operation under light loads.
  • Compact 150mm size allows for broader chassis compatibility and more space for cable management.
  • Flat, fully modular cables reduce clutter and improve airflow within the PC case.

Cons

  • The 36dB average noise level when the 2000 RPM FDB fan is active might be noticeable under heavy loads.
  • Flat cables, while aiding airflow, can sometimes be stiffer and harder to route in tight spaces.
  • The 150mm length, while compact, might still be a tight fit for some ultra-small form factor cases.

Dimension Scores

Efficiency & Output9/10

The 80 Plus Gold certification ensures 90% efficiency at 50% load, and ATX 3.1 with PCIe 5.1 support provides robust power delivery for modern GPUs.

Noise Level7/10

The Zero RPM fan mode keeps the fan off under light loads, but the 2000 RPM FDB fan produces an average of 36dB when active, which is above silent operation.

Build Quality8/10

The inclusion of 100% Japanese Capacitors points to a focus on reliability and durability for stable performance.

Cable Management8/10

Fully modular flat cables offer flexibility in connecting only necessary components and improve airflow compared to non-modular or sleeved round cables.

Best For

  • New PC builds featuring NVIDIA RTX 40/50 Super or AMD GPUs requiring ATX 3.1 and PCIe 5.1 power delivery.
  • System builders prioritizing power efficiency and component longevity due to 80 Plus Gold certification and Japanese capacitors.
  • Compact PC builds where a 150mm PSU length is crucial for chassis compatibility and cable management.

Not Recommended For

  • Budget-constrained builds where a lower wattage or less efficient PSU would suffice.
  • Users who demand absolute silence even under heavy loads, as the fan activates above 60℃ with a 36dB average noise level.
  • Existing systems without ATX 3.1 or PCIe 5.1 compatible components, as some features would be underutilized.

Watch Out For

  • The 2000 RPM FDB fan has an average noise level of 36dB when active, which could be audible during demanding tasks.
  • While fully modular, flat cables can sometimes be less flexible than sleeved round cables, potentially making routing challenging in very small cases.
  • The Zero RPM fan mode only keeps the fan off until 60℃, meaning the fan will spin up and produce noise once that temperature threshold is met.

What Buyers Say

This Redragon RGMS-850W PRO PSU is listed with a future release date of August 13, 2024, so there are no actual user reviews available yet. Based on its specifications, it's positioned as a modern, high-efficiency power supply for demanding PC builds. The inclusion of ATX 3.1 and PCIe 5.1 support with a 12VHPWR cable suggests it's ready for the latest NVIDIA GPUs, while its compact 150mm size and fully modular flat cables aim to simplify installation and improve case aesthetics.

“Man, if this thing delivers on the ATX 3.1 and PCIe 5.1 like it says, and those Japanese caps hold up, it's gonna be a killer for my new RTX build, especially with that compact size!”

Common Praise

  • Expected high power efficiency due to 80 Plus Gold certification.
  • Anticipated compatibility with next-gen GPUs thanks to ATX 3.1 and PCIe 5.1 standards.
  • Predicted long-term stability from 100% Japanese Capacitors.
  • Expected quiet operation under low loads due to Zero RPM fan mode.
  • Improved cable management and airflow from fully modular, flat cables.

Common Complaints

  • Potential for audible fan noise (36dB) once the Zero RPM threshold is exceeded under load.
  • Flat cables might be less flexible than some users prefer for intricate routing.
  • The 150mm length, while compact, may still pose challenges in extremely small form factor cases.

Ownership Tips

  • The actual noise profile of the 2000 RPM FDB fan under sustained heavy load will be a key factor for long-term satisfaction.
  • The real-world flexibility and routing ease of the flat modular cables will determine how 'tidy' cable management truly becomes.
  • The effectiveness of the Zero RPM mode in maintaining silence during typical desktop use versus gaming sessions will be important.

Buying Guide

When you're looking at power supplies, you're basically picking the heart of your PC. You need enough wattage to power all your components, especially your graphics card. Efficiency ratings like 80 Plus Gold tell you how much power is actually delivered to your components versus wasted as heat. Modern PSUs also need to keep up with new standards like ATX 3.1 and PCIe 5.1 if you're planning on using the latest, power-hungry GPUs.

Wattage (850 watts)

This is the total power your PSU can deliver. Think of it like the engine size in a car; you need enough horsepower to move your vehicle (PC components) efficiently. An 850W unit is suitable for most high-end gaming PCs with a single powerful GPU.

80 Plus Gold Certification

This rating indicates how efficiently the PSU converts AC power from your wall socket to DC power for your PC. Gold means it's at least 87% efficient at 20% load, 90% at 50% load, and 87% at 100% load. Higher efficiency means less wasted energy, less heat, and potentially lower electricity bills.

ATX 3.1 & PCIe 5.1

These are the latest power delivery standards designed for modern, power-intensive graphics cards, particularly NVIDIA's RTX 40 series and beyond. They allow for higher power excursions (brief spikes in power draw) without system instability, ensuring your GPU gets the power it needs when it needs it.

Fully Modular

This means you only plug in the cables you actually need for your components. It's like having custom-length cables for everything, reducing clutter inside your case, improving airflow, and making your build look much cleaner.

Alternatives

If you need more power for dual GPUs or extreme overclocking, look for PSUs with 1000W or higher. For basic systems or less demanding GPUs, a 650W or 750W 80 Plus Bronze or Silver unit might be more cost-effective.
