Benchmarks: Vitals
As expected for an RTX 3080 base unit, system-wide power draw reaches almost 450W when gaming. The Corsair PSU running at 70 per cent capacity is no cause for concern, though a little more headroom wouldn't go amiss, particularly if you're planning to upgrade to thirstier components at a later date.
Elsewhere, Scan does well to find an optimal balance between low temps and low noise with a 4000D Airflow chassis and a 360mm liquid cooler. The system is quiet when idle, and emits a steady hum when gaming that isn't overly distracting.
