The Tempest PSU PRO 850W is a Black 850W gaming power supply with 80 Plus Bronze efficiency certification, Active PFC (APFC), 120mm cooling fan, 1.5m cable length, SATA x6, MOLEX x3, ATX 24-pin, PCIe 6+2-pin, CPU 4+4-pin and FDD 4-pin connectors, EU plug, RoHS certified and 1.5 kg. Six SATA power connectors for storage and ARGB hub daisy-chaining. Three MOLEX connectors for legacy peripherals and fan controllers. PCIe 6+2-pin for GPU power. CPU 4+4-pin for Intel and AMD CPU power headers. ATX 24-pin for motherboard main power. Active PFC for clean power factor correction. 80 Plus Bronze for verified efficiency across the 850W load range.

80 Plus Bronze Efficiency + Active PFC + SATA x6 + PCIe 6+2 + CPU 4+4 + 120mm Fan: The Six Tempest PSU PRO Specifications That Define Its Efficiency, Connectivity and Thermal Management.

The 80 Plus Bronze certification confirms the Tempest PSU PRO 850W operates at a minimum of 82% efficiency at 20% load, 85% efficiency at 50% load and 82% efficiency at 100% load — the Bronze efficiency standard meaning that at the 50% load point (approximately 425W) that a mid-to-high-end gaming build sustains during typical gameplay, the PSU converts 85% of the AC input into usable DC power rather than heat, reducing both the power drawn from the wall socket and the thermal output the PSU fan must manage. The Active PFC (APFC) corrects the power factor of the AC input to approach unity across the full 850W load range — reducing reactive current draw on the building’s electrical circuit and ensuring the PSU operates correctly with the EU 230V 50Hz power supply without the power factor degradation that passive PFC designs allow at partial load. The SATA x6 connectors provide simultaneous power to up to six SATA devices — NVMe drive SATA power adaptors, 2.5" and 3.5" hard drives, ARGB fan hubs, ARGB LED controllers and optical drives across six independent SATA power connections without requiring daisy-chain splitters that add resistance to the power path. The PCIe 6+2-pin connector delivers the 75W per connector GPU supplemental power that current-generation discrete graphics cards require through the 8-pin (6+2) PCIe power configuration — the split 6+2 design fitting both 6-pin and 8-pin GPU power inputs on the same connector without an adaptor. The CPU 4+4-pin connector powers both Intel LGA and AMD AM4/AM5 CPU power headers with the same connector — the 4+4 split fitting both 4-pin and 8-pin CPU EPS headers that different motherboard generations use. The 120mm fan manages the thermal output of the 850W conversion process at noise levels appropriate for a gaming environment — the 120mm blade sweep area moving sufficient airflow through the PSU enclosure to maintain component temperatures within operating range at full 850W load.

Because Six SATA Connectors, Three MOLEX, a PCIe 6+2, a CPU 4+4 and an ATX 24-pin on One 850W 80 Plus Bronze PSU Means Every Device in the Build Gets Power From the First Cable Run — Without Splitters, Adaptors or a Second PSU.

Mount the Tempest PSU PRO 850W in the ATX PSU bay. Route the 1.5m cables through the case cable management. Connect the ATX 24-pin to the motherboard main power header. Connect the CPU 4+4-pin to the CPU EPS header — 4-pin or 8-pin. Connect the PCIe 6+2-pin to the GPU 8-pin or 6-pin power input. Connect SATA power to all six SATA devices — drives, hubs and controllers. Connect MOLEX 4-pin to legacy fan controllers and peripherals. Connect FDD 4-pin to any FDD or legacy small peripheral. Connect the EU plug to the wall socket. Active PFC corrects the power factor. 80 Plus Bronze converts 85% of the 850W input to usable DC at 50% load. The 120mm fan manages PSU thermal output. Every connector occupied. Every device powered. Build complete.
