DEEPCOOL PX1200G 1200W ATX 3.0 80+ Gold Fully Modular Power Supply

The Deepcool PX1200G is a 1200W fully modular power supply built to the ATX12V V3.0 (ATX 3.0) standard, making it a future-ready choice for high-performance desktop builds. Its fully modular cable design means you attach only the cables your system requires, resulting in a cleaner build interior and improved airflow throughout your chassis. A standout feature is the included PCIe Gen 5.0 12VHPWR connector, which can deliver up to 600W to power-hungry discrete graphics cards — ideal for current-generation high-end GPUs. The unit also ships with two EPS connectors for multi-CPU or HEDT platforms and three PCIe connectors for multi-GPU or accessory configurations. The PX1200G holds 80 Plus Gold certification and an additional Cybenetics Platinum rating, achieving efficiency of 90% or higher under typical 50% load conditions. This dual certification is a reliable indicator of energy efficiency and reduced heat output during everyday operation. For acoustics and longevity, the unit uses a 135mm fluid dynamic bearing (FDB) fan paired with a hybrid semi-fanless mode. In this hybrid setting the fan remains at zero RPM under light loads, only spinning up once system demand crosses a defined threshold — keeping noise to a minimum during everyday tasks. The internal topology — Active PFC combined with a Half-Bridge Series Resonant LLC converter and DC-to-DC voltage regulation — supports stable power delivery and transient load handling in line with ATX 3.0 requirements, including the ability to supply three times the continuous GPU power for 0.1 ms excursion events without triggering protection circuits. Six protection mechanisms are built in: over-power protection (OPP), over-voltage protection (OVP), short-circuit protection (SCP), over-temperature protection (OTP), over-current protection (OCP), and under-voltage protection (UVP).
