Technical specification
The GAMDIAS HELIOS P2-1000G is a next‑generation 1000 W 80 PLUS Gold fully modular power supply designed for high‑end gaming and creator PCs built around the latest ATX 3.1 and PCIe Gen 5.1 standards. It features a native 16‑pin 12VHPWR connector (up to 600 W) for next‑gen GPUs, full DC‑DC LLC resonant design with 100% industrial‑grade Japanese capacitors and a 135 mm fluid dynamic bearing fan for quiet, long‑life operation. Double‑Gold certified (80 PLUS Gold and Cybenetics Gold) with up to 92% efficiency at 50% load and support for up to 235% power excursion, the HELIOS P2‑1000G delivers peak stability, transient handling and heavy‑duty protections for modern flagship systems.

- ATX 3.1 & PCIe Gen 5.1 ready: Fully compliant with ATX 3.1 and PCIe Gen 5.1, including a native 16‑pin 12VHPWR cable capable of delivering up to 600 W directly to supported GPUs without adapters. [web:2439][web:2440][web:2443][web:2446][web:2447]
- Double‑Gold certified efficiency: Rated 80 PLUS Gold and Cybenetics Gold, providing stable power with up to 92% efficiency at 50% load to reduce power loss, heat and noise. [web:2440][web:2442][web:2443][web:2446][web:2451]
- Full DC‑DC, LLC resonant design with Japanese capacitors: Uses a full DC‑DC, LLC resonant circuit and 100% industrial‑grade Japanese capacitors for cleaner output, better transient response and long‑term reliability. [web:2440][web:2443][web:2446][web:2451]
- 135 mm fluid dynamic bearing fan with semi‑fanless mode: A 135 mm FDB fan provides strong cooling and low noise; silent / hybrid modes reduce or stop fan operation at low loads to minimize noise. [web:2440][web:2444][web:2446][web:2451]
- Heavy‑duty protection and power excursion support: Supports up to triple GPU power excursion and double total power excursion while providing OVP, UVP, OPP, OCP, OTP and SCP protections for safe, stable operation. [web:2440][web:2443][web:2446][web:2450][web:2451]
