AI Verdict
A 1000-watt, 80 Plus Gold, fully modular ATX power supply with a 135mm magnetic levitation fan, suitable for high-power PC builds.
This 1000-watt, 80 Plus Gold, fully modular power supply is a strong choice for high-power systems needing clean builds and quiet operation at lower loads. Its renewed status makes it a cost-effective option, but the lack of specified ATX 3.1 compliance means it might not be the absolute best fit for bleeding-edge GPU setups.
If you're building with a brand-new, high-power GPU like an RTX 40-series or RX 7000-series, look for a PSU explicitly stating ATX 3.1 and PCIe 5.1 compliance with a native 12V-2x6 connector.

Pros
- Delivers 1000 watts of power, supporting high-end components and multiple graphics cards.
- 80 Plus Gold certification means 87-90% efficiency at 20-100% load, reducing wasted energy and heat.
- Fully modular design allows you to connect only necessary cables, simplifying cable management.
- Features a 135mm magnetic levitation fan with Zero RPM mode for quiet operation under low to medium loads.
- Built with 100% Japanese 105°C capacitors for consistent power delivery and durability.
- Modern Standby compatibility enables faster wake-from-sleep times and improved low-load efficiency.
Cons
- Cables can be thick and stiff, making routing challenging in some cases.
- Some users report the fan can become noticeable under heavy gaming or rendering loads.
- The ATX form factor and physical size might block cable management space in smaller mid-tower cases.
- As a renewed product, it may have a shorter warranty period compared to a new unit's 10-year warranty.
- This specific renewed model does not specify ATX 3.1 or PCIe 5.1 compliance, which newer RM1000x units offer for modern GPUs.
Dimension Scores
The 1000-watt output is substantial, and 80 Plus Gold certification provides 87-90% efficiency at typical loads.
The 135mm magnetic levitation fan with Zero RPM mode ensures near-silent operation at low to medium loads, though some users note fan noise under heavy use.
It uses 100% Japanese 105°C capacitors, indicating a focus on long-term reliability and stable power delivery.
The fully modular design simplifies cable routing by allowing removal of unused cables, but some users find the cables stiff.
Best For
- High-end gaming PCs with power-hungry CPUs and GPUs requiring 1000W.
- Custom PC builds where clean cable management is a priority due to the fully modular design.
- Users prioritizing quiet operation during light computing tasks with the Zero RPM fan mode.
- Cost-conscious builders seeking a high-wattage, efficient PSU without buying new.
Not Recommended For
- Budget PC builds that don't require 1000 watts of power.
- Small form factor (SFF) PC cases due to its standard ATX size.
- Users who need guaranteed ATX 3.1 and PCIe 5.1 compliance for the absolute newest graphics cards.
Watch Out For
- The renewed status means you might receive a unit with minor cosmetic imperfections, though none were specifically reported for this ASIN.
- Some users experienced rare early failures with the new RM1000x, so a renewed unit could carry a slightly higher risk of issues.
- Voltage fluctuations under extreme load were observed by a small number of users, potentially affecting stability for overclockers.
- The included cables might be stiff, making it difficult to achieve a tidy build in tight spaces.

What Buyers Say
This renewed CORSAIR RM1000x is often seen as a smart buy for its wattage and features, but you're definitely getting an older model without the latest ATX 3.1 compliance. Many users appreciate the quiet operation at lower power draws and the flexibility of fully modular cables. The main trade-off for the renewed price seems to be the potential for stiffer cables and the lack of native PCIe 5.1 support for modern GPUs. It's a workhorse, but not the newest kid on the block.
“Man, this 1000W PSU is a beast for my 4080, but those cables are a pain to bend, and I wish it had that new 12VHPWR plug built-in, but for the price, I can't complain too much.”
Common Praise
- Provides ample 1000W power for high-end systems.
- Fan remains off during light loads, resulting in silent operation.
- Fully modular cables make for cleaner and easier PC builds.
- Considered a very reliable power supply by many users.
- High efficiency with 80 Plus Gold certification helps reduce heat and power consumption.
Common Complaints
- Cables can be thick and rigid, making them difficult to bend and route neatly.
- Fan noise becomes noticeable under heavy system load, contrary to 'whisper quiet' claims.
- Some users reported rare instances of units failing within the first few months.
- The physical size of the PSU can interfere with cable management in certain mid-tower cases.
- Lacks ATX 3.1 and PCIe 5.1 native connectors for the newest graphics cards.
Ownership Tips
- The Zero RPM fan mode really does keep things quiet during web browsing and light gaming, the fan only kicks in when I'm really pushing my GPU.
- Routing the 24-pin ATX cable was a struggle, it's super stiff and barely fit behind my motherboard tray.
- Even though it's renewed, my unit looked practically new, no scratches or anything visible.
- I had to buy a separate 12VHPWR adapter for my RTX 40-series card since this model doesn't have a native one.
- The power delivery feels rock solid, no weird crashes or instability even during long gaming sessions.
Frequently Asked Questions
What does 'Renewed' mean for this power supply?
Amazon Renewed products are pre-owned and inspected to work and look like new. They come with the Amazon Renewed Guarantee, but the warranty from Corsair might be shorter than a new unit.
Is this power supply noisy?
It features a 135mm magnetic levitation fan with a Zero RPM mode, meaning the fan won't spin under low to medium loads, making it very quiet. Under heavy loads, some users have reported the fan becomes audible.
Does this PSU support the latest graphics cards?
It has EPS12V connectors for wide compatibility. However, this specific renewed model does not list ATX 3.1 or PCIe 5.1 support, which is important for native 12V-2x6 connectors found on some newer, high-end GPUs. You might need adapter cables for those.
What kind of warranty does this renewed unit have?
While new RM1000x units typically come with a 10-year warranty, renewed products usually have a shorter warranty, often backed by the seller or Amazon Renewed program. The product listing does not specify the exact warranty duration for this renewed unit.
Are the cables included with this fully modular power supply?
Yes, as a fully modular unit, all necessary cables are included, allowing you to connect only the ones your system requires.
Buying Guide
When you're looking at power supplies, you need to think about how much juice your PC parts need and how much noise you can tolerate. A higher wattage like 1000W is for serious gaming rigs or workstations. Efficiency ratings like 80 Plus Gold tell you how much power is wasted as heat, so higher is better for your electricity bill and PC temperature. Modular cables are a huge win for keeping your PC's insides looking clean and improving airflow.

Alternatives
If this renewed unit doesn't quite fit, look for power supplies explicitly stating ATX 3.1 and PCIe 5.1 compliance for native 12V-2x6 connectors, or consider lower wattage options like 750W or 850W if your build doesn't demand 1000W.
