Slim Specs Table

Exceptional Quiet Operation

The Pure Power 12 1000W uses a 120mm rifle-bearing fan that keeps noise levels to just 31. 6 dB under typical loads. This makes it ideal for silent builds where acoustics matter as much as raw power. The fan’s intelligent speed control ensures cooling only when needed, reducing wear and extending the MTBF to 100,000 hours.

ATX 3.1 & PCIe 5.1 Ready

With ATX 3.1 compliance and PCIe 5.1 compatibility, this PSU supports the latest GPU and CPU power demands, including multi-rail transient response for stable power delivery. It includes both a PCIe 5.1 cable and standard PCIe 6+2 cables, offering flexibility for current and next-gen hardware without compromise.

Comprehensive Protection Suite

Built-in safety features include over current, over power, over voltage, overheating, short circuit, surge & inrush protection, and under voltage safeguards. These protections ensure your components remain safe during power fluctuations or hardware faults, making this PSU a dependable foundation for any high-end system.

Non-Modular Cable Management

The non-modular design means all cables are permanently attached, which can simplify installation for some builders. Cable lengths are generous—motherboard cable at 55 cm, PCIe at 60 cm, and SATA cables ranging from 50 cm to 95 cm—ensuring reach across most case sizes without strain.
