GAMDIAS Helios P2 1000G 1000W 80+ Gold ATX 3.1 Fully Modular Power Supply

The GAMDIAS Helios P2 1000G is a 1000W fully modular ATX power supply built for current-generation gaming and creator PCs. It is 80 PLUS Gold certified, with the manufacturer rating efficiency up to 92% at 50% load, which helps cut wasted power and heat inside the case. The unit is designed to the ATX 3.1 specification (ATX12V v3.1) and the PCIe Gen 5.1 connector standard. It ships with a native 16-pin 12VHPWR (12+4 pin) cable rated to deliver up to 600W to a single graphics card, so modern high-power GPUs connect without adapters. Alongside it are four 6+2-pin PCIe connectors, a 24-pin main power connector, and 4+4-pin plus 8-pin CPU connectors, covering current NVIDIA and AMD graphics cards and high-core-count processors. Storage and legacy devices are served by twelve SATA, four Molex and one Floppy connector. Cooling uses a 135mm sleeve-bearing fan with automatic, temperature-based speed control; note that the spec sheet lists no zero-RPM silent mode. A full DC-to-DC design with an LLC resonant circuit supports stable rail output, active PFC delivers a 0.99 power factor, and the PSU supports C6/C7 power states. A complete protection set is included: OVP, UVP, OPP, SCP, OCP and OTP.
