Corsair RM1000e
Reddit take
AI summary of the Reddit excerpts below — not a quote
The Corsair RM1000e is a 1000W fully modular power supply frequently recommended for high-end PC builds requiring significant power headroom. It is generally well-regarded for its reliability and compatibility with modern GPUs, though some users note that 1000W is overkill for many standard gaming setups. The 2025 revision is the current standard, offering updated ATX 3.1 support.
Pros
- High power headroom (1000W) suitable for future-proofing and high-end GPUs like the RTX 5080
- Fully modular design simplifies cable management
- Includes a versatile mix of single and daisy-chained 8-pin PCIe cables
- Frequently available at competitive price points or on sale
Cons
- Often considered overkill for mid-range builds where 650W-750W is sufficient
- Some reports of erratic internal sensor readings, such as rapid temperature swings
Caveats
- Older 2022 models may require a PCIe to 12V-2x6 adapter for certain modern GPUs, whereas newer versions support it natively
- Troubleshooting issues like 'no video' have been reported post-installation, though these are often system-specific rather than universal PSU failures
Best for
- High-end gaming builds with power-hungry components
- Users planning future GPU upgrades who want extra wattage headroom
Avoid if
- You are building a mid-range PC where a lower wattage unit (650W-800W) would save money
- You prioritize the absolute quietest operation, as some users prefer competitors for noise levels

Power Supply: Corsair RM1000e (2025) 1000 W Fully Modular ATX Power Supply ($199.99 @ Best Buy Canada)
Corsair RMe Series RM1000e and "Corsair rm1000e" are literally the same thing
For the PSU, I went with 1000W ATX 3.1 since I’m planning to upgrade to a 5080 (possibly Gaming Trio) and wanted extra headroom for future GPUs.

I'd only go with a 1000W PSU because the Corsair RM1000e is currently on sale for $80

I'm not really bothered by RGB but something subtle could be nice. Quiet is more important though, so if that means no glass, that's ok
PSU: Corsair RM1000e
I also figure i will replace my PSU with a Corsair RM1000e, which will give me plenty more headroom for anything i do down the line, whilst moving away from the 650W that is considered iffy for a 6800XT.
My PSU started failing last week so I went to Best Buy and they said the Corsair RM1000e will work with my device. I’ve plugged everything in, everything seems to turn on but I don’t get any video.
