1000W Platinum ATX Power Supply

The ASUS ROG STRIX 1000P delivers 1000W of continuous power through an ATX 3.1 compliant design. It carries 80Plus Platinum and Cybenetics A+ noise certifications for high efficiency and quiet operation. The unit measures 160 x 150 x 86mm and weighs 2.91 kg. An MTBF rating above 120,000 hours at 25°C indicates long-term reliability.

Upgrade from lower-wattage or older-standard units

Replacing a supply below 1000W or one lacking ATX 3.1 support adds headroom for modern GPUs and the native 16-pin connector. The jump is worth it when your build demands the combined 12V rail capability of 1000W and the PCIe Gen 5 cable included in the box. Builders staying with current hardware that draws less power will not see a benefit.

Fits standard ATX builds with modern GPU cabling

The supply requires an ATX case cavity and provides a full modular cable set including a 610mm motherboard cable, two 1000mm CPU cables, and a 750mm PCIe Gen 5 16-pin-to-16-pin cable. Four additional 750mm 6+2-pin PCIe cables, two SATA 1-to-3 cables, and one peripheral 1-to-3 cable cover storage and accessories. A single 100-240Vac input cord completes the kit.

Questions about this item

Will the 160 x 150 x 86mm PSU fit a standard ATX case?

Yes, the unit follows the ATX form factor and measures 160 x 150 x 86mm, matching the standard ATX mounting pattern used by most cases.

How do I connect the 16-pin PCIe 5.0 cable correctly, and what mistake should I avoid?

Plug the 16-pin connector fully into the PSU side first, then into the graphics card; the most common error is leaving the PSU-side socket partially seated, which can cause power loss.

When should I expect to replace the cooling fan based on the 120,000-hour MTBF rating?

The MTBF of >120,000 hrs at 25°C is a statistical average for the whole unit; fans typically wear sooner, so plan a check after several years of heavy use.
