Overview
The Corsair RM750e is a 750W fully modular ATX power supply from Corsair's RMe line, positioned as the sensible value tier below the RMx series. It targets mainstream gaming and workstation builds that want quiet, reliable power without paying for a flagship unit.
This page is a curated summary. CoreForge did not lab-test this power supply. We verify the specifications against Corsair's official product page and summarize independent lab findings, then add the Canadian pricing and value perspective. The full sources are linked below.
Read this first: there are two different RM750e units
This is the single most important thing to know before you buy, and it is easy to miss because both units carry the same product name.
The 2023 revision (CP-9020262-NA) is ATX 3.0 and PCIe 5.0 compliant, rated 80 PLUS Gold. Independent measurements from LTT Labs list it as ATX 3.0 with a 120 mm rifle bearing fan, and it does not ship with a native 12V-2x6 cable.
The 2025 revision (CP-9020295-NA) is the one Corsair currently lists. According to Corsair's official product page, it is ATX 3.1 certified and PCIe 5.1 compliant, carries Cybenetics Gold rated efficiency, and includes a dedicated native 600W 12V-2x6 GPU power cable in the box.
Both are still sold at Canadian retailers side by side. If you are building around a modern GPU that uses the 12V-2x6 connector, you want the 2025 unit. Check the model code, not just the name.
Verified specifications
According to Corsair's official product page for the current RMe RM750e, the unit is fully modular, uses industrial-grade 105°C-rated capacitors, and is backed by a seven-year warranty. The casing is 140 mm long, which Corsair notes fits nearly any modern case. Canadian retailer listings for the ATX 3.1 version also specify a 120 mm rifle bearing fan with a zero RPM mode, so the fan stops entirely at low load.
One warranty clarification worth making: Corsair's ten-year warranty applies to the RM series, not the RMe series. The RMe units, including this one, are seven years. Both are long by industry standards, but they are not the same.
What the independent data shows
LTT Labs, which runs its own instrumented power supply testing, catalogued the RM750e with a Cybenetics ETA Platinum efficiency rating and a Cybenetics Lambda A- noise rating. In plain terms: measured efficiency came out above the 80 PLUS Gold badge on the box, and it tested as a genuinely quiet unit.
That matches how this unit is generally positioned: not a record-setter, but a well-behaved, quiet, honestly-rated 750W supply.
Is 750W the right number?
For the build we have been assembling across these reviews, a Ryzen 7 9800X3D at 120W paired with an RTX 5070 at 250W, 750W is comfortable. It leaves real headroom for transient spikes, which is exactly what the ATX 3.1 standard is designed to handle.
Where 750W gets tight is future-proofing. If you think you may move to a significantly higher-power GPU later, stepping up to the 850W version of the same unit costs relatively little now and saves buying a second PSU later. That is a judgment call about your upgrade plans, not a flaw in this unit.
The Canadian angle
We verified Canadian availability and pricing directly. At the time of writing, Amazon.ca listed the RM750e (2025) in white at $213.66 CAD, and the unit is also carried by Newegg.ca and Best Buy Canada. Corsair maintains a Canadian product page for the current model as well.
A practical note: colour variants are not priced the same. The white version often carries a premium over black, and the older 2023 revision is frequently discounted below the current one, which is precisely why the generation confusion above matters. If you see a suspiciously cheap RM750e, check whether it is the ATX 3.0 unit.
Check the live price on Amazon.ca, Newegg.ca, Best Buy Canada, Canada Computers and Memory Express before buying, and confirm the model code matches the generation you want.
Bottom line
A solid, quiet, well-warrantied 750W unit that suits most single-GPU builds. Buy the 2025 ATX 3.1 revision unless you have a specific reason not to, confirm the model code, and compare the current Canadian price across variants before ordering.
