RM1000x SHIFT Fully Modular ATX Power Supply - Modular Side Interface - ATX 3.0 & PCIe 5.0 Compliant - Zero RPM Fan Mode - 105°C-Rated Capacitors - 80 PLUS Gold Efficiency - Black

Good PSU, good cables

The idea of having the modular connections shifted to the side of PSU is awesome. This is the perfect PSU in my opinion.

Bought the PSU only to find out that the 1000 Watts doesn’t come with a 600 Watts cable but only 450 Watts. Only 1200 Watts model comes with a 600 Watts cable. To get 600 Watts on PCIe cable you need to order another one from Corsair. Complete waste of my time. Returned and refunded. Not sure how to attach image but I have PSU box image that says <=450 watts ATX 3.0.

I recently upgraded to the Corsair RM850x SHIFT, and honestly, the side-mounted connectors are such a smart design. If you’ve ever struggled with plugging in cables in tight cases or near the bottom of your PC, you’ll appreciate how much easier this layout makes everything. Cable management was way cleaner, and it actually gave me more space to work with inside the case. Performance-wise, it’s rock solid. 850W is plenty of power for my setup, and everything has been running super stable. The unit is also really quiet — the fan barely kicks in, even under load, and when it does, it’s still whisper-quiet. Build quality is what you’d expect from Corsair — sturdy, premium feel, and comes with all the cables you need. Modular design means you only use what you need, keeping the build neat and airflow-friendly. If you're building a new PC or upgrading, the SHIFT is 100% worth considering. It’s not just about power — it’s about convenience and clean aesthetics, too.

No more cramming my fingers and twisting my hand, just to add or remove something Fit well in my nzxt H7 flow, has a premium quality, good cables, and plenty of sata connectors, I can easily hotswap cables without worrying about the 3.5 hdd cage getting in my way The only thing I hate is the included 12+4pin cable doesn't match the other cables

TUTTO OK

Item was as described, fits with most PC cases. Came with plenty of PCIE cables for graphics cards that does not use the new pcie 12v high power connection.

Works as expected. Quiet. Reliable. Plenty of power for the RTX 5090. Clever arrangement of the cables, easy to assemble. Pricey but worth it.
