The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the Corsair RM750e is the consensus mid-range 750W pick for builds in the RTX 4070 / RX 7800 XT class. tomshardware.com (verified tier) explicitly writes that 'the RM750e is built to compete with the best power supplies' and praises its balance of features, performance, and cost. kitguru.net's broader RMe coverage notes the LLC resonant topology and DC-DC conversion shared with pricier units.
What reviewers liked
- Endorsed by tomshardware.com (verified tier) as competing with the best PSUs in its category
- ATX 3.1 / PCIe 5.1 compliance with native 12V-2x6 cable at a lower price than the RM850x
- r/buildapc consensus treats it as A-tier with multi-year reliability reports
- Cybenetics Gold efficiency and 105°C-rated capacitors in a compact, fully modular package
Where it falls short
- At least one r/buildapc thread specifically warns against it on coil-whine grounds, an issue the related RM850e has also been flagged for
- 750W is on the edge for anything beyond RTX 4070 / 4070 Ti Super class with high-end CPUs
- Smaller verified-purchase footprint (175 Amazon reviews) than the higher-wattage RMx siblings
- Newer 2025 revision exists alongside older stock, creating SKU confusion for buyers

Specialist-community sentiment on r/buildapc is largely positive, with multiple owners describing it as 'basically silent' and A-tier, including a 'super efficient, super silent' assessment in a dedicated 2023-revision thread. That said, we want to surface a real disagreement: one r/buildapc thread specifically advises against the RM750e on coil-whine grounds, echoing the complaints that historically dogged the related RM850e. A r/bapcsalescanada commenter notes the 2025 refresh appears to have addressed the whine issue with the updated 12V-2x6 cable revision.
For buyers building around a single mid-range or upper-mid-range GPU and not planning a 4080-tier upgrade, the trust-weighted consensus places this unit as the value-conscious pick from a top-tier line, with the caveat that coil-whine sensitivity is worth checking on arrival.
