Product information

Description

Straight Power 12 1500W is an ATX 3.0 power supply with 80 PLUS® Platinum certification that combines high efficiency, a single large 12V rail and near-silent operation. It includes native 12VHPWR connectors for PCIe 5.0 graphics cards as well as multiple 6+2‑pin PCIe connectors for current GPUs, modular sleeved cables up to 100 cm, and premium Japanese 105°C capacitors for reliable, long-term use.

Advantages

The unit delivers up to 93.9% efficiency under typical loads, reducing power consumption and system heat. Its ATX 3.0 compliance and integrated 12VHPWR connectors make it compatible with next‑generation GPUs while also supporting existing cards via 6+2‑pin connectors. A high-end Silent Wings fan and an optimized funnel-shaped inlet provide effective cooling with minimal noise, and the wire-free interior allows unobstructed airflow. Full-bridge LLC topology and high-quality components ensure stable voltage regulation and low ripple for reliable performance.

Key specifications

  • Form factor: ATX 3.0
  • Rated power: 1500 W continuous
  • Efficiency certification: 80 PLUS Platinum (up to 93.9%)
  • 12V rail: single massive 12V rail, high transient capability
  • Connectors: 2 × native 12VHPWR (PCIe 5.0), 4 × PCIe 6+2‑pin
  • Fan: Silent Wings high-end fan with fluid-dynamic bearing
  • Capacitors: Japanese 105°C capacitors
  • Cables: Modular sleeved cables, up to 100 cm
  • Topology: full-bridge LLC for improved regulation and low ripple

How to use

Install the Straight Power 12 1500W into a compatible ATX chassis following standard PSU mounting procedures. Connect the native 12VHPWR plugs directly to compatible PCIe 5.0 graphics cards, or use the included 6+2‑pin PCIe connectors for current-generation GPUs. Attach the modular sleeved cables as needed for motherboard, CPU, storage and peripheral power, keeping cables routed to maintain unobstructed airflow. Ensure the PSU is connected to a properly rated mains supply and that all connectors are fully seated before powering the system.

Recommendations

Use this PSU in high-performance or workstation systems where sustained power delivery and low noise are required. Verify GPU compatibility with 12VHPWR connectors and ensure adequate case ventilation to maximize cooling and component lifespan.
