As a seasoned PC enthusiast who’s been through countless builds and upgrades over the years, I can confidently say that investing in a reliable power supply is non-negotiable for any gaming rig. And when it comes to PSUs, Corsair’s RMx series with ATX 3.1 compliance has caught my attention.
With top-tier graphics cards and processors increasingly demanding more power, a robust and dependable power supply unit (PSU) becomes indispensable. Therefore, when selecting components for a gaming PC, it is essential not to compromise on the power supply.
When searching for top-tier Power Supply Units (PSUs) as suggested in Game Rant’s guide, remember that it’s crucial to keep an eye on technological advancements. While discussions about processor and graphics card updates are common, power supplies are not exempt from major improvements. A notable recent development is the emerging ATX 3.1 form factor, which is poised to replace all existing ATX 3.0 PSUs soon. So, stay informed to ensure you’re making the best choices for your build!
Although Corsair didn’t pioneer the launch of ATX 3.1-compatible power supply units (PSUs), enhancements to their RMx line suggest a glimpse into what may lie ahead in terms of high-performance gaming PCs.
What is ATX 3.1?
It might be tricky to grasp the specifics if you’re new to the idea of ATX. In a nutshell, ATX, short for Advanced Technology Extended, pertains to the design and dimensions of a Power Supply Unit (PSU). Although several PSU types exist, ATX or SFX are typically preferred in gaming PCs. These options are continually upgraded, with the updates being denoted by numbers to differentiate them.
In essence, while there’s only a small variation, the key distinction between versions 3.0 and 3.1 of ATX is indeed significant.
The significant shift involves the update of the previously used 12VHPWR connector, now replaced with a more advanced 12V-2×6 connector. The gaming community has held concerns regarding the 12VHPWR connector since its adoption by Nvidia for 40 Series GPUs. Since 2022, this connector has encountered numerous issues that have led to system and hardware damage. Fortunately, with ATX 3.1 PSUs, modifications have been implemented to minimize failure risks. The new 12V-2×6 Connector rectifies many of the original connector’s shortcomings by incorporating longer conductor terminals and shorter sense pins that automatically shut off your GPU if the connection becomes loose.
If you’ve got an RTX 4080 or RTX 4090, consider upgrading your power supply unit (PSU) to one compatible with ATX 3.1 as soon as possible. This step will help maintain the well-being and long lifespan of your graphics card.
Corsair RMx Series Updates: What You Need To Know
The Corsair RMx Series overhaul affects three models: the RM1000x, RM850x, and the RM750x.
For those who find it hard to discern, there’s no need for concern. All these Power Supply Units share the same ATX 3.1 compliance and are compatible with the enhancements introduced in the RMx series. The uniqueness among these three models lies solely in their power output (wattage), as indicated by their respective names.
If you’re unsure about selecting the appropriate wattage for your Power Supply Unit (PSU), take a look at this comprehensive guide from Game Rant for further insights.
ATX 3.1 Compliance
For individuals who currently possess an RTX 4090 or RTX 4080 graphics card, or for those intending to update their computer with contemporary hardware, purchasing a Power Supply Unit (PSU) that adheres to ATX 3.1 standards is highly suitable.
In essence, ATX 3.1 is primarily designed to rectify issues with the 12VHPWR connector, but it also plays a role in streamlining cable organization within your setup. The new 12v-2×6 cable provides a user-friendly solution by allowing a direct connection from the PSU to the GPU, eliminating the need for additional extension cables and thereby reducing cable clutter.
Improved Thermals, Efficiency & Lower Noise Levels
Beyond just being thankful for the ATX 3.1 upgrade, it’s worth noting that enhancements in the RMx series PSUs from Corsair don’t end there. They’ve also paid close attention to the internal aspects of these power supplies, leading to significant boosts in performance, temperature management, and overall dependability.
Initially, the fundamental circuit board (PCB) of the RMx Power Supply Unit (PSU) has undergone a comprehensive renovation, incorporating a state-of-the-art six-layer design reinforced with robust, high-temperature capacitors rated at 105°C. Furthermore, the fan on the RMx PSU has been substantially upgraded, enhancing its silence. The new 140mm fan now employs a low-decibel fluid dynamic bearing and is compatible with Corsair’s “Zero RPM” feature. This implies that the fan will not spin until the PSU reaches a specific temperature threshold.
The latest models of Corsair RMx power supply units exhibit increased efficiency compared to previous versions, with a remarkable 91% energy efficiency rating and an A+ grade in sound level from Cybenetics.
Should You Make The Upgrade?
Buying new parts for your gaming PC always brings a bit of uncertainty. It seems like there’s a constant stream of new components being launched, each claiming the newest and best improvements. Making a decision about whether it’s the ideal moment for an upgrade can be quite challenging.
In simpler terms, it’s rarely ideal to upgrade immediately. Many gamers often choose to wait for the next best product, but there’s usually something better just around the corner. However, if you already own a high-end graphics card like the RTX 4090 or RTX 4080 and aim for its longevity and good condition, investing in a quality power supply unit (PSU) such as the Corsair RMx 3.1 ATX could be beneficial.
