⚡ Key Features

• Native 12V-2x6 cable delivers up to 600W to a modern graphics card — no daisy-chained adapter between the PSU and the GPU
• ATX 3.1 and PCIe 5.1 compliance means the unit is designed to absorb the short power excursions today's GPUs produce
• 850W of continuous output leaves room for a high-core-count CPU alongside a power-hungry card
• 80 PLUS Bronze efficiency keeps waste heat and running cost down versus an uncertified supply
• 120 mm Hydro Dynamic Bearing fan is rated for 40,000 hours — the bearing type that outlasts plain sleeve fans in hot rooms
• S²FC Smart and Silent Fan Control ramps the fan only as the load demands, so idle and light gaming stay quiet
• Full protection suite — OCP, OPP, OTP, OVP, SCP and UVP — guards the rest of the build if something goes wrong
• Compact 140 mm depth fits comfortably in mid-tower cases with room left for cable routing
• 100,000-hour MTBF and a 5-year Seasonic warranty
