AI Verdict
A 1000W ATX power supply bundled with a 600W PCIe 5.0 12VHPWR cable, designed for high-power PC builds with modern GPUs.
This bundle is a strong fit for high-performance PC builds, especially those featuring modern, power-intensive GPUs that utilize the 600W PCIe 5.0 12VHPWR connector. The 1000W power supply provides ample headroom, and its fully modular design helps manage the necessary cabling.
If you don't need 1000W or the 600W 12VHPWR cable, consider a lower wattage RMx series PSU or a different model without the PCIe 5.0 cable to save on cost.

Cons
- Some users report audible coil whine from the RM1000x PSU, particularly under load or in 220-240V regions.
- The modular cables can be stiff, making routing challenging in compact cases.
- A few users experienced difficulty with the 12VHPWR cable seating fully or reported GPU issues, requiring cable replacement.
- The PSU's 160mm depth can limit cable management space in smaller mid-tower cases.
Dimension Scores
The 1000W PSU is 80 PLUS Gold certified (some revisions Platinum at 115V) and compliant with ATX 3.1 and PCIe 5.1, delivering stable power and handling transient spikes.
It features a 135mm magnetic levitation fan with a Zero RPM mode for silent operation at low loads, but numerous user reports mention noticeable coil whine under load.
Constructed with 100% Japanese 105°C capacitors and backed by a ten-year warranty, indicating a focus on long-term durability and component quality.
The fully modular design simplifies cable routing by eliminating unused cables, though some users find the cables stiff, which can complicate management in tight spaces.
Best For
- High-end gaming PCs with power-hungry RTX 40-series GPUs requiring a 12VHPWR connection.
- Workstations needing stable 1000W power delivery for demanding tasks.
- PC builders prioritizing a fully modular design for a clean aesthetic.
- Users seeking a long-term power supply solution with a ten-year warranty.
Not Recommended For
- Budget-constrained PC builds, as the 1000W capacity and premium features may be overkill.
- Small form factor (SFF) cases where the 160mm PSU depth might cause fitment or cable routing issues.
- Users highly sensitive to minor electrical noises, due to reported coil whine instances.
Watch Out For
- The RM1000x PSU has documented instances of coil whine, with some users hearing it over system fans or even at idle.
- Some users reported the 12VHPWR cable not fully seating into the GPU connector, leading to troubleshooting or replacement.
- The product's 'Date First Available' of July 4, 2024, is in the future, meaning the 1,526 reviews and 4.6/5 rating are aggregated from the RM1000x PSU itself, not this specific bundle.
- The modular cables, while flexible, have been described as stiff by some, potentially complicating cable management in tight spaces.

What Buyers Say
It's important to note that while this bundle has a 4.6/5 rating from 1,526 reviews, the 'Date First Available' is July 4, 2024, indicating these reviews are likely aggregated from the CORSAIR RM1000x PSU itself, not this specific new bundle. Many users praise the RM1000x for its stable power delivery and the convenience of its fully modular design. However, a recurring complaint is the presence of coil whine, which some find distracting, especially under load. There are also mixed experiences with the 12VHPWR cable, with some reporting difficulty seating it or initial GPU issues.
“Man, this RM1000x is mostly awesome, powers my 5080 no problem with that new cable, but sometimes I swear I hear a tiny high-pitched whine when I'm just browsing, kinda annoying for a premium PSU.”
Common Praise
- Provides stable and consistent power output for high-end components.
- Fully modular cabling makes PC building and cable routing cleaner.
- The Zero RPM fan mode keeps the system quiet during light use.
- Includes a native 12VHPWR cable, removing the need for adapters for modern GPUs.
- The ten-year warranty offers peace of mind regarding product longevity.
Common Complaints
- Audible coil whine reported by multiple users, sometimes even at idle or under moderate load.
- The included modular cables can be stiff, making them difficult to bend and route neatly in a case.
- Some users experienced issues with the 12VHPWR cable not fully inserting or causing GPU instability.
- The PSU's physical size (160mm depth) can be a tight fit in certain mid-tower cases, impacting cable management space.
Ownership Tips
- The Zero RPM fan mode actually works, keeping the PSU fan off until a certain load threshold is met, contributing to a quieter system during non-intensive tasks.
- The stiffness of the cables means you might need to plan your cable runs carefully, especially behind the motherboard tray, to avoid bulging side panels.
- Even with the 12VHPWR cable, ensuring it's fully seated with an audible 'click' is crucial to prevent potential issues, as partial insertion can lead to problems.
- The 1000W capacity provides significant headroom, allowing for future component upgrades without needing a new PSU.

Buying Guide
When buying a power supply, you're looking for stable, consistent power delivery to all your PC components. Wattage is important, but don't just pick the highest number; match it to your system's needs with some headroom for future upgrades. Modularity means you only plug in the cables you need, which makes building and cable management much easier. The 12VHPWR cable is specifically for newer, high-power graphics cards, so if you have one, this cable is a must-have to avoid using bulky adapters.

Alternatives
If you need less than 1000W, look for PSUs in the 750W-850W range with 80 PLUS Gold efficiency. If you don't have a PCIe 5.0 GPU, you can opt for a PSU without the dedicated 12VHPWR cable. For extremely quiet operation, prioritize models with a fanless mode that extends to higher loads or those known for minimal coil whine.
