Corsair RM750x 750W 80 PLUS Gold Fully Modular ATX 3.1 PSU
Corsair’s current-generation RM750x: a quiet, fully modular 750W supply for high-performance single-GPU gaming PCs.
The RMx series has been Punch’s default choice for enthusiast builds for years, and the latest RM750x brings the range up to ATX 3.1 and PCIe 5.1 with a native 12V-2×6 connector. It is aimed at gaming PCs and creator systems with one powerful graphics card, where the priorities are clean power, low noise and tidy cabling rather than the sheer output of a 1000W-plus unit.
Power delivery
The unit delivers 750W continuous with a single 62.5A +12V rail, is 80 PLUS Gold certified and independently rated Cybenetics Gold for efficiency and Cybenetics A+ for noise. Corsair builds it entirely with 105°C-rated Japanese electrolytic capacitors and rates it for continuous operation at up to 50°C ambient, with a 100,000-hour MTBF. Modern Standby support means fast wake times on Windows systems that use it.
Connectivity
Cabling is fully modular. Alongside the 24-pin ATX lead and two 4+4 pin EPS connectors there is one native 12V-2×6 (12+4 pin) cable for current graphics cards, two 6+2 pin PCIe connectors, and a further 12V-2×6 to dual 8-pin cable for cards that use two 8-pin inputs. Eight SATA connectors on two cables and three peripheral connectors cover storage and accessories. Corsair’s Type 4 embossed cables are flexible and come with low-profile combs for neat routing.
Cooling and noise
A 140mm fan on a fluid dynamic bearing with a magnetic dome structure runs quietly and lasts, and Zero RPM mode keeps it stationary at low and medium loads so the unit is silent for desktop work and lighter games.
Compatibility
The 160mm-long casing fits almost all modern ATX cases, including many compact mid-towers. Corsair covers the RM750x with a ten-year warranty. Punch can fit it in a new gaming or creator build.
Ideal for
- Single-GPU gaming PCs up to upper mid-range and high-end cards
- Quiet creator and home-office workstations
- Builders who want a native 12V-2×6 connector without a 1000W unit
