The NZXT PA-7B3BB-EU is an ATX power supply unit designed to deliver a total output of 750 watts, suitable for a range of PC builds. It operates with an 80 Plus Bronze certification, indicating its efficiency level under typical system loads. The unit incorporates active Power Factor Correction (PFC) to maintain stable and consistent power delivery to internal components. With a compact depth of 140 mm, it fits within the standard ATX footprint, allowing for installation in various computer chassis while providing adequate space for cable routing.
Thermal performance is handled by a single 120 mm fan that provides active cooling to regulate internal temperatures during operation. This model features a non-modular cable design, where all power cables are permanently attached to the unit. For hardware safety, the power supply includes a suite of standard protection features. These safeguards protect against over current, over voltage, under voltage, overheating, and short circuits, contributing to overall system stability and component longevity.
