Know before you buy
The 80 PLUS Titanium rating is the highest efficiency standard available, meaning the unit wastes very little power as heat. This results in lower energy consumption and reduced heat output compared to lower-rated power supplies.
During low to medium loads, the fan will stop spinning entirely for silent operation. Once the power supply reaches a certain temperature or load threshold, the 135mm fan will engage to keep components cool.
Yes, with 1000W of power and eight 6+2 pin PCI-Express connectors, this unit is well-equipped to handle high-end builds that utilize multiple graphics cards.
A fully modular design allows you to connect only the cables you actually need. This significantly reduces cable clutter inside your case, which improves airflow and makes your build look much cleaner.
The AX1000 uses 100% Japanese capacitors, which are known for their high reliability and longevity. Additionally, Corsair backs this unit with a ten-year warranty, providing long-term peace of mind.
The AX1000 follows the standard ATX form factor, but it has a length of 170mm. You should check your specific case specifications to ensure there is enough clearance for a power supply of this depth.
