Explaining the CORSAIR PSU Lineup (2023)

PSUs are an absolutely crucial component to PC, as it acts as the heart and breathes life to your build. At CORSAIR, we carry a long understanding of the PSU's importance and have reliably brought countless builds to life with our PSUs. As PC builds vary widely, we've sought to provide a PSU for every need and possibility - from entry-level PCs to accommodating the highest demanding builds such as workstations. Below, you'll be able to quickly gain an understanding of our PSU lineup, including ATX, SFX and Modular PSUs.

The CX-M Series provide the go-to PSUs for entry-level or mid-level builds. Capable of accommodating up to a RTX 4070 Ti or 7800 XT, the CX Series PSUs are also budget friendly. Also, a great option if you're building a system that won't even be used for gaming. Just want a reliable PSU to power a system that'll only be used for the basics (web browsing, productivity, etc.)? The CX-M Series has got you.

Starting with the base RM Series of PSUs, this begins a lineage of respectable and popular choices amongst PC enthusiasts. The reason why? Well, multiple reasons: reliable, fully modular, 80 PLUS® Gold efficiency certification, and minimal noise (thanks to zero-RPM fan mode). These specifications are established staples amongst all of our PSUs denoting "RM" - RMx, RMe, etc.

For a budget-friendly option that still offers the staples of reliability, full modularity, 80 PLUS® Gold efficiency certification, and minimal noise - the RMe Series is the suitable choice. In regard to the RMe's differences (vs RM/RMx), the RMe is equipped with Taiwanese capacitors (vs. Japanese) and a 120mm fan (vs. 140mm/135mm).

For those who may be more sensitive to noise, the RMx Series harnesses even lower noise levels thanks to its 135mm magnetic levitation fan. The fan utilizes custom engineered rotors designed for high performance, minimal bearing noise, and utmost reliability.

Released earlier this year, the RMx SHIFT Series received reception of being a game-changer, due its innovative side cable connection positioning (pictured below). Whilst it may sound like a minor adjustment, it greatly eases the PC building process and voids the hassle of awkwardly attempting to squeeze your hand into a tight space. Offering up to 1200W, you'll be able to power high-end gaming PCs (RTX 4090/7900 XTX, i9-14900K/7950X) without any problem.

The RM Series PSUs set a pretty high bar, but now we have our HX Series PSUs, which are not just capable of accommodating high-end gaming PCs, but also begin to tread into workstation PC territory. On top of offering up to 1500W, the HX Series also features 80 PLUS® Platinum efficiency. You'll also still be able to enjoy silent operation with zero-RPM fan mode. If you're a hardcore enthusiast, you may even opt for the HXi specifically to monitor power supply performance (voltages, wattage), toggle single or multi rail mode, efficiency percentage, and control the fan speed via iCUE.

Built like an absolute tank, the AX Series PSUs are outfitted to accommodate builds with the highest demand and provide the ultimate future proofing. On top of offering up to a whopping 1600W, the AX Series PSUs also bear the highest efficiency 80 PLUS® rating available. The perfect choice for workstation PCs outfitted with the most power-hungry hardware.

Lastly, we have the SF/SF-L Series PSUs for those who are interested inSFF cases. Offering up to 1000W, these PSUs are highly capable of accommodating high-end components. Perfect for those who want a tiny but mighty build without any compromises. These SFX PSUs would also be a suitable option for SFF home theater PCs.
