Overview

The Thermaltake Smart BX1 650W is an 80+ Bronze certified power supply built for mainstream desktop systems. Its 650W capacity is well-matched to single-GPU gaming PCs, home workstations, and everyday desktops, delivering reliable power with at least 82% efficiency at typical loads. The unit accepts 100V to 240V input automatically, eliminating the need for a manual voltage selector and making it compatible with electrical standards worldwide.

Thermaltake equips the Smart BX1 with all-flat cables—a notable quality-of-life feature at this price point that makes cable routing and management significantly easier than bundled round cables. Cooling comes from a 120mm hydraulic bearing fan, a design that typically runs quieter and lasts longer than the sleeve bearing fans found in many competing budget units. While the non-modular cable layout means all leads are permanently attached, the flat form factor helps keep unused cables tucked away in most mid-tower and full-tower cases.

Pros & Cons

👍 Pros

  • 80+ Bronze efficiency reduces energy waste and heat output during operation
  • All-flat cable design simplifies routing in mid-tower and full-tower cases
  • 120mm hydraulic bearing fan provides quieter and longer-lasting cooling than sleeve bearing alternatives
  • 100V–240V auto-ranging input works on any standard power grid without manual switching
  • 650W capacity supports mainstream single-GPU desktop builds with adequate headroom

👎 Cons

  • Non-modular design means all cables are permanently attached, leaving unused cables to manage
  • 650W may be insufficient for high-end dual-GPU or enthusiast overclocking configurations
  • No semi-passive fan mode, so the fan runs continuously even at low loads
  • Lacks 80+ Gold or higher certification for users seeking maximum efficiency
