## Long description

Straight Power 12 1500W is a high-performance ATX 3.0 power supply with 80 PLUS® Platinum certification, designed for silent and efficient operation in demanding desktop systems. It includes native support for two 12VHPWR connectors for next‑gen PCIe 5.0 graphics cards plus four PCIe 6+2‑pin connectors for current GPUs, modular sleeved cables up to 100 cm, and a single strong 12V rail delivering 1500 W continuous power.
Advantages
The PSU combines Platinum-level efficiency of up to 93.9% with an ultra-quiet Silent Wings fan and a funnel-shaped inlet for improved airflow and reduced turbulence. It handles large transient power spikes (up to twice its rated power), uses full-bridge LLC topology for low ripple and stable voltages, and relies on high-quality Japanese 105°C capacitors for long-term reliability. Modular, sleeved cables simplify installation and reduce internal clutter.
