AI Verdict
This 750W ATX 3.1 power supply with a 135mm magnetic levitation fan and included 600W 12VHPWR cable is for PC builders needing modern GPU power delivery and quiet operation.
This PSU is a strong fit for modern PC builds, especially those using NVIDIA's latest GPUs, due to its ATX 3.1 compliance and included 600W PCIe 5.0 12VHPWR cable. The fully modular design and 105°C Japanese capacitors also point to a focus on build quality and ease of use.
If you're running a very high-end AMD GPU that needs three PCIe power cables, consider stepping up to an 850W or higher RMx series PSU to ensure adequate cable provision.

Dimension Scores
The PSU is 80 PLUS Gold certified and ATX 3.1 compliant, providing excellent power quality and efficiency when cool.
It uses a 135mm magnetic levitation fan and is generally quiet at low to mid loads, though some users report it's not the quietest under heavy load.
Constructed with 100% All Japanese 105°C Capacitors and high-quality internal components, ensuring unwavering power delivery and long-term reliability.
The fully modular design allows for connecting only necessary cables, and it comes with individually sleeved all-black cables for improved aesthetics and routing.
Best For
- Gaming PCs with NVIDIA 40-series GPUs needing a native 12VHPWR connection.
- New PC builds requiring ATX 3.1 compliance for future-proofing.
- Users prioritizing clean cable management due to its fully modular design.
- Systems where stable power delivery and component longevity are critical.
Not Recommended For
- Compact ITX builds where a 160mm PSU might be too long.
- Budget-focused builds where the premium features and included 12VHPWR cable might be overkill.
- High-end systems with power-hungry AMD GPUs that might require more than two PCIe power cables, potentially necessitating an 850W or higher PSU.
Watch Out For
- The 750W unit may require an 850W or higher model if your AMD graphics card needs three separate PCIe power cables.
- Older RM750x models had in-cable capacitors which made cable routing a pain, so check if this 2024 version still has them if you're super particular about cable bends.
- While generally quiet, some users have noted the fan isn't the quietest when the PSU is under significant load.

What Buyers Say
This specific RM750x model, released in July 2024, is the updated ATX 3.1 version, which is a big deal for anyone building a new PC with a modern GPU. The inclusion of the 600W 12VHPWR cable right in the box means you don't have to hunt for adapters or separate cables for your RTX 40-series card. Users consistently point to the fully modular design as a huge win for keeping builds clean and tidy. While the 135mm magnetic levitation fan generally keeps things quiet, a few people have noticed it can get a bit louder when the system is really pushing it.
“Dude, this PSU is legit for my 4070 Ti, no more ugly adapter cables, and my build looks so much cleaner now. Only thing is, when I'm really gaming hard, I can hear the fan a bit, but it's not a dealbreaker.”
Common Praise
- Native 600W 12VHPWR cable included, eliminating the need for adapters.
- Fully modular design simplifies cable routing and improves case airflow.
- Quiet operation at low to moderate system loads due to the magnetic levitation fan.
- High-quality Japanese 105°C capacitors contribute to perceived longevity and stable power.
- ATX 3.1 compliance provides peace of mind for current and future component compatibility.
Common Complaints
- Fan noise becomes noticeable under high system loads.
- The 750W unit might not have enough PCIe cables for some AMD GPUs that require three separate connections.
- In-cable capacitors on previous RMx versions could make cable bending and routing difficult.
- The 160mm length is slightly longer than some standard ATX PSUs, which can be a tight fit in certain cases.
Ownership Tips
- The individually sleeved cables feel premium and are easier to route than flat ribbon cables.
- The 12VHPWR cable is stiff, so plan your GPU installation carefully to avoid excessive bending.
- The PSU's 160mm length means double-checking case clearance, especially in smaller mid-towers.
- The zero RPM fan mode at low loads makes the system practically silent for everyday tasks.
Frequently Asked Questions

Buying Guide
When you're picking a power supply, you're basically choosing the heart of your PC. It needs to deliver enough stable power to all your components without breaking a sweat, especially your graphics card and CPU. Look for wattage that matches your system's needs, and efficiency ratings like 80 PLUS Gold, which means less wasted energy and heat. The type of cables and modularity also matter a ton for how easy your build will be and how clean it'll look.
wattage: 750W
This number tells you the maximum power the PSU can supply. For a gaming PC, 750W is a sweet spot for many mid-to-high-end GPUs and CPUs, ensuring everything gets enough juice without being over-specced.
Fully Modular
This means you only plug in the cables you actually need for your components. Think of it like a custom-fit suit for your PC's wiring – less clutter, better airflow, and a much cleaner look inside your case compared to a PSU with all cables permanently attached.
PCIe 5.0 / Gen 5 12VHPWR PSU Cable
This is crucial for newer, high-power graphics cards like NVIDIA's RTX 40-series. It's a single, more robust cable that can deliver up to 600W directly to your GPU, replacing the need for multiple 8-pin adapters that can be messy and less reliable.
100% All Japanese 105°C Capacitors
Capacitors are like tiny batteries that store and release power smoothly. Japanese capacitors, especially those rated for 105°C, are known for their superior quality, stability, and longer lifespan, meaning your PSU will likely last longer and provide more consistent power.
Alternatives
If this 750W unit isn't enough, look for PSUs with higher wattage (850W or 1000W) and ensure they are also ATX 3.1 compliant with a native 12VHPWR cable. If you need a smaller physical size, search for PSUs with a length under 160mm.
