⚡ Key Features

• A 135mm dual-ball-bearing fan is rated to roughly 80,000 hours — about twice the life of the sleeve bearings usually found at this price.
• 648W of the 650W budget sits on the +12V rail at 54A, which is exactly where a gaming CPU and graphics card draw from.
• Six protection circuits — OPP, OVP, UVP, SCP, OCP and OTP — plus an MTBF above 120,000 hours at 25°C.
• ASUS's etched cables bend easily during installation, so routing behind the motherboard tray takes less fighting.
• The DIY-friendly CPU power connector uses a distinct clip and colour scheme, so you plug it in correctly first time.
• Low-ESR electrolytic capacitors are specified to run around 50°C below their safety limit, which is what keeps a supply healthy over years of use.
• 80 PLUS Bronze certification with Active PFC and full-range 100–240 Vac input suits Egyptian mains directly.
• Standard 150 × 150 × 86 mm ATX body fits any conventional tower case.
• Backed by a six-year ASUS warranty.
