Chieftec Vita SM3 BPX-750-C
 | Outdated Product The Chieftec Vita SM3 750 W power supply is among the affordable options for gaming and versatile builds with Core i7/Ryzen 7-class processors and mid-range to advanced GPUs (but not flagships). The model is positioned as a simplified alternative to the Chieftec Proton series while retaining reliability and modern features. The main highlight is support for the ATX 3.1 standard, which is rarely found in budget-segment models. Thanks to this, the Vita SM3 is ready for next-gen graphics cards, including models with PCIe 5.0, and uses a 12V-2x6 cable, eliminating the need for adapters. The main +12V rail with the full 750 W output is designed to power configurations with graphics cards such as the GeForce RTX 4070 Ti or Radeon RX 7800 XT, as we...ll as their lower and more affordable counterparts if the owner wants a power headroom to avoid stressing the PSU. The 80+ Bronze certificate guarantees baseline energy efficiency and optimal power distribution. Cooling is handled by a quiet 120 mm fan with automatic speed control that stays quiet under light load and ramps up as temperature rises. The cables are semi-modular: the main lines are fixed, and the additional ones connect as needed, simplifying cable management and improving case airflow. A full set of protections is implemented — from overvoltage and overload to short circuit and overheating. The official manufacturer’s warranty is 3 years. |
