## Long description

Straight Power 12 1500W is an ATX 3.0 power supply with 80 PLUS Platinum certification designed for high-end systems. It delivers 1500W continuous power on a single 12V rail, includes native 12VHPWR connectors for next‑gen PCIe 5.0 graphics cards and multiple 6+2‑pin PCIe connectors for current GPUs, and features a Silent Wings fan and optimized internal airflow for quiet, reliable cooling.
Advantages
The PSU provides high efficiency (up to 93.9%), reduced power consumption and lower heat output thanks to its 80 PLUS Platinum rating. Native ATX 3.0 support with two 12VHPWR connectors and four 6+2‑pin PCIe connectors ensures compatibility with both current and upcoming graphics cards. A robust single 12V rail can handle short-term power spikes up to twice the rated power, improving stability under heavy transient loads. Premium Japanese 105°C capacitors and full‑bridge LLC topology deliver stable voltages, low ripple and long component life. Modular sleeved cables up to 100 cm make installation neater and improve case airflow.
