As an enthusiast and content writer for Playtechzone.com, I’m always on the lookout for components that strike the perfect balance between performance, reliability, and value. Power supplies are often overlooked in system builds, but their importance cannot be overstated. A reliable PSU ensures stable power delivery, protects your components, and contributes to the overall longevity of your system. Today, we’ll be taking a deep dive into the Corsair RM750 (2019), examining its features, performance, and whether it deserves a spot in your next build.
Corsair RM750 (2019): A Silent Guardian for Your System
The Corsair RM750 (2019) aims to deliver a premium power solution without breaking the bank. With an 80 PLUS Gold certification, fully modular design, and a ten-year warranty, it certainly ticks many of the right boxes. But how does it stack up against the competition, especially its slightly pricier sibling, the RM750x? Let’s delve into the details.
Here’s a quick rundown of what we’ll be covering:
- Specifications and Component Analysis: Unveiling the heart of the RM750 and comparing it to the RM750x.
- Performance Evaluation: Examining load regulation, hold-up time, efficiency, noise levels, and more.
- Pros and Cons: Highlighting the strengths and weaknesses of the RM750.
- Verdict: Is the Corsair RM750 (2019) the right PSU for you?
Under the Hood: Specifications and Component Analysis
The RM750 (2019) is built by CWT, a reputable OEM in the PSU industry, and boasts a fully modular design, allowing you to connect only the cables you need, reducing clutter and improving airflow within your case. It utilizes a half-bridge LLC resonant converter on the primary side and synchronous rectification with DC-DC converters on the secondary side, a topology known for its efficiency and stable output.
Key Specifications:
| Feature | Corsair RM750 (2019) |
|---|---|
| Wattage | 750W |
| Efficiency | 80 PLUS Gold (88-91%) |
| Form Factor | ATX12V v2.4, EPS 2.92 |
| Modular | Fully Modular |
| Fan | 140mm Rifle Bearing Fan (HA1425M12F-Z) |
| Warranty | 10 Years |
Component Comparison: RM750 vs. RM750x
One of the most significant distinctions between the RM750 and the RM750x lies in their component selection. While both PSUs are built by CWT, the RM750x utilizes higher-quality Japanese capacitors from brands like Nichicon and Nippon Chemi-Con, known for their longevity and reliability. In contrast, the RM750 opts for more budget-friendly Chinese Elite capacitors.
Furthermore, the RM750x features the highly regarded NR135L fan from Corsair, renowned for its quiet operation and durability. The RM750, on the other hand, employs a 140mm Hong Hua fan, which, while decent, doesn’t quite match the NR135L’s reputation.
Here’s a table summarizing the key component differences:
| Component | Corsair RM750 (2019) | Corsair RM750x (2018) |
|---|---|---|
| Primary Capacitors | Elite (Chinese) | Nichicon, Nippon Chemi-Con (Japanese) |
| Fan | Hong Hua HA1425M12F-Z | Corsair NR135L |
These component choices contribute to the price difference between the two models, with the RM750x commanding a slight premium. However, it’s essential to consider whether the performance and longevity benefits of the RM750x justify the additional cost for your specific needs.
Performance: Delivering on its Promises
The RM750 (2019) excels in its performance, consistently delivering stable voltages and operating quietly even under demanding loads. Tom’s Hardware’s testing revealed excellent load regulation, holding voltage levels within tight tolerances across various load scenarios. The PSU also boasts a robust hold-up time, ensuring your system remains stable during brief power interruptions.
Efficiency and Noise Levels:
True to its 80 PLUS Gold certification, the RM750 (2019) achieves high efficiency levels, peaking at over 90% at medium loads. This translates to less wasted energy, lower operating temperatures, and reduced electricity bills.
Furthermore, the PSU operates silently during light to moderate loads thanks to its semi-passive fan mode. Even under heavy load, the 140mm fan spins up gradually and remains relatively quiet.
Modern Standby Support:
The RM750 (2019) supports the Modern Standby mode introduced in Windows 10. This feature allows for faster wake-up times from sleep, similar to smartphones and tablets, enhancing the overall user experience.
Pros and Cons: Weighing the Advantages and Disadvantages
Pros:
- Excellent Performance: Stable voltage regulation, robust hold-up time, and high efficiency.
- Quiet Operation: Semi-passive fan mode and a relatively quiet fan even under load.
- Fully Modular Design: Reduces cable clutter and improves airflow.
- 10-Year Warranty: Provides peace of mind and demonstrates Corsair’s confidence in the product.
- Modern Standby Support: Enables faster wake-up times for a more responsive system.
Cons:
- Component Quality: Utilizes Chinese capacitors compared to the Japanese capacitors in the RM750x.
- Fan Choice: The Hong Hua fan, while decent, doesn’t quite match the reputation of the NR135L found in the RM750x.
- Price: While competitively priced, it’s only slightly cheaper than the higher-end RM750x.
The Verdict: A Solid Performer with a Value Proposition
The Corsair RM750 (2019) is a compelling option for budget-conscious builders who prioritize performance, reliability, and quiet operation. Its excellent performance, fully modular design, and ten-year warranty make it a strong contender in its price range.
However, the slightly more expensive RM750x, with its higher-quality components and superior fan, might be a more compelling option for users who prioritize longevity and are willing to spend a bit more for peace of mind.
Ultimately, the best PSU for you depends on your specific needs, budget, and priorities. If you’re looking for a reliable and efficient PSU that won’t break the bank, the Corsair RM750 (2019) is a solid choice.
