PSU or Power Supply Unit plays an essential role to deliver a seamless experience whether you’re playing high-end games or performing crucial tasks such as 3D Animation, Video Editing & Rendering, Graphics Designing, and others as it supplies constant & stable power to all the components in your PC. Hence, choosing the right PSU is of paramount importance, but finding out it is quite daunting, especially for first-time builders as there are hundreds of options out there.
So, before making a final purchase decision, paying attention to in-depth research and reading genuine recommendations of gamers or enthusiasts who are already using it would be great. This can indeed help you filter out a trustworthy brand name like CORSAIR offering different series of PSUs, out of which we’ll discuss mainly three PSUs: RM (80 Plus Gold), HX (80 Plus Platinum), and AX (80 Plus Titanium).
But, before proceeding further, it would be better to add to your knowledge that all three PSUs (RM, HX, & AX) are CORSAIR Type-4 power supplies that are compatible with CORSAIR “PCIe 5.0 or Gen 5 Power Cable” which can easily deliver power from CORSAIR Type-4 PSUs to the most advanced PCIe 5.0 graphics cards. Hence, we can say that these CORSAIR Type-4 PSUs are PCIe 5.0 Compatible.
Now, Let’s Reveal About Them One by One!
RM SERIES: The RM SERIES of PSUs is CORSAIR’s 80 Plus Gold Certified featuring high-efficiency, quiet operation, & fully modular cables that make it an advisable option for gaming as well as general PC use. It’s designed majorly for better performance of your system. Below are a few examples from CORSAIR RM SERIES PSUs:

CORSAIR RM750x, RM850x, and RM1000x: Which One Is Better?
All these Corsair RM750x, RM850x, and RM1000x are the power supplies that you can opt for, but the choice among them ultimately depends on your particular requirements or needs. If we talk about performance, all three power supplies are 80 Plus Gold Certified, which means they are highly efficient and can deliver stable power to your components. The main difference between the three models is their wattage output, the RM750x provides 750 watts, the RM850x provides 850 watts, and the RM1000x provides 1000 watts.
If you have a high-end gaming PC or workstation with multiple graphics cards or other power-hungry components, the RM1000x may be the best choice as it can handle more power output. However, for most standard builds, the RM750x or RM850x is more than sufficient. And if you’re tight on budget, the RM750x is typically the most affordable option, but RM850x is slightly more expensive and the RM1000x is the most expensive, so choose accordingly.

CORSAIR AX1600i, AX1000, and AX850: Which One Is Better?
The CORSAIR AX1600i, AX1000, and AX850 are all high-end power supplies designed for enthusiasts and professionals who need a reliable and efficient power source for their systems. In the case of overall performance and features, the CORSAIR AX1600i is the best of the three. It has the highest wattage output at 1600 watts, 80+ Titanium efficiency, and a fully modular design. However, it is also the most expensive of the three.
The CORSAIR AX1000 is the middle ground in terms of wattage output at 1000 watts, but it still has 80+ Titanium efficiency and a fully modular design. It is also slightly more affordable when compared to AX1600i. The CORSAIR AX850 has a lower wattage output at 850 watts and 80+ Gold efficiency, but it’s still a reliable & efficient power supply available at an affordable price range.
If you’re purchasing from the CORSAIR’s PSU SERIES (RM, HX, AX), do not forget to consider the following important factors:
Power Requirements:
CORSAIR RM, HX, and AX Series power supply units (PSUs) are all designed to deliver reliable power supply to your PC components. And when it comes to power requirements, the amount of power drawn by a PSU depends on the components installed in the computer, the load on the components, and the efficiency of the PSU. However, in general, PSUs with higher efficiency ratings consume less power. In fact, all three of these series offer PSUs with 80+ Gold, 80+ Platinum, and 80+ Titanium efficiency ratings.
As an example, let’s compare two PSUs, the CORSAIR RM850x and the CORSAIR AX850. Even though both are 850 Watt PSU, the RM850x has an 80+ Gold efficiency, while the AX 850 has an 80+ Titanium efficiency rating. Under a load of 50%, the RM850x would consume approximately 412 watts, while the AX850 would consume approximately 395 watts. At 100% load, the RM850x would consume approximately 835 watts, while the AX850 would consume approximately 814 watts. So, with this information, it’s clear that the CORSAIR AX850 consumes slightly less power in comparison with CORSAIR RM850x.
Efficiency:
The CORSAIR RM, HX, and AX Series Power Supplies (PSUs), are manufactured for different performance levels & features, but when it comes to energy efficiency, the AX Series offers the highest level of efficiency. For example, let’s compare the CORSAIR RM850x and the CORSAIR AX850 from CORSAIR RM & AX Series respectively. Although both PSUs are rated for 850 watts of power output, the AX 850 is manufactured for higher-end systems and available with a higher price tag.
Also, the RM850x has an 80 Plus Gold efficiency rating, meaning that it’s rated for at least 87% efficiency at 20% load, 90% efficiency at 50% load, and 87% efficiency at 100% load. The AX850, on the other hand, has an 80 Plus Titanium efficiency rating, which means it’s rated for at least 90% efficiency at 10% load, 92% efficiency at 20% load, and 94% efficiency at 50% load, and 90% efficiency at 100% load. So, in this particular case, the CORSAIR AX850 is more energy efficient than the RM850x.
PCIe 5.0 Compatible:
Since RM, HX, and AX is CORSAIR type-4 power supplies FULLY COMPATIBLE with CORSAIR “PCIe 5.0 or Gen 5 Power Cable” which can easily deliver power up to 600W from CORSAIR Type-4 PSUs to the latest NVIDIA RTX 4000 Series graphics cards. Hence, we can say that these CORSAIR type-4 PSUs are PCIe 5.0 compatible.
Noise level: The noise level of a PSU can be an important consideration if you're looking to build a quiet system. The AX and HX series use a Zero RPM fan mode, which means that the fan will not spin when the system is idle or under light loads. The RM series also has a low noise level, but its fan does not have the Zero RPM mode.
Modularity:
All three RM, HX, and AX CORSAIR Series are fully modular power supplies, meaning that all the cables can be detached from the unit. And, it makes cable management quite easier, so it’s a good choice for those who want maximum flexibility when it comes to cable management. The RM Series is comparatively a budget-friendly option while HX Series is typically more expensive, designed especially for powerful PCs, and offers excellent efficient & quiet operation. Talking about AX Series, it’s a high-end power supply that is more expensive, manufactured for high-performance systems. In short, if you want maximum flexibility in cable management, the RM series is the best choice.
