CORSAIR RM750x ATX 3.1 (CP-9020285-NA)
A standard RMx with documented cable runs, distinct from SHIFT
RM750x CP-9020285-NA is a candidate when 750 W meets the system requirement and the case has room for a 160 mm PSU plus its cables. Its documented separate PCIe and EPS runs help make the connection plan concrete. Compare it with the shorter RM750e if the drive cage limits space, and keep the standard RMx, SHIFT and older revisions separate when shopping.
Consider it when
- A checked 750 W build that benefits from known conventional PCIe and EPS cable runs.
Look again when
- The case needs a shorter PSU or the intended GPU requires an unverified native-cable rating.
THE SPACE IT NEEDS
Leave room beyond the PSU body
- PSU body length
- 160mm
The body length excludes the working space needed for plugs and cable bends. Drive cages and the case layout can reduce that space.

The checks that can change your choice
Do not add the alternative cable to the native port simultaneously
This exact model records two separate PCIe 6+2 cables and two EPS 4+4 cables. The listed dual-8-pin alternative uses the native 16-pin position. The exact native cable wattage was not independently established in the catalog, so verify it for the selected graphics card rather than borrowing the 1000 W model’s figure.
Check the whole power path
Compare the CPU and exact graphics card requirements with the PSU capacity and included connector arrangement. Count independent cable runs where the GPU manual requires them. Use only cables approved for this exact power supply; similar-looking modular plugs do not establish compatible wiring.

Exact CP-9020285-NA standard RMx model, not SHIFT or the 2021 revision. Includes 2 separate conventional PCIe 6+2 cables and two EPS 4+4 cables. Use only cables approved for this exact PSU. The current product page also lists a 12V-2x6-to-dual-8-pin alternative cable; it cannot be used simultaneously with the native 16-pin cable on the same port. Native 16-pin cable wattage was not independently established for this exact wattage variant.
