## Long description

ASRock PRO-750B is a 750 W ATX power supply designed for desktop PCs that require a stable single-rail power source with standard ATX connectivity. It delivers up to 750 watts total power, accepts a universal 100–240 V AC input at 50/60 Hz and includes a 24-pin ATX motherboard connector. The unit uses 80 PLUS Bronze efficiency to balance performance and energy use, integrates a 120 mm active cooling fan, and comes in a compact ATX form factor with black housing. Included cables cover common internal connections, with SATA power leads of varying lengths and a 60 cm motherboard cable for flexible routing.
Advantages
The ASRock PRO-750B provides a combination of rated 750 W output and 80 PLUS Bronze certification to reduce wasted energy and improve system stability under typical desktop loads. A 120 mm fan supports active cooling while aiming to keep acoustic levels low. Native dual-color 12V 2x6 (PCIe) connectors enhance visibility during installation, and the black finish integrates with most system builds. The PSU also incorporates a suite of safety protections to guard components from abnormal power events and is backed by a manufacturer warranty.
Suitable for
Standard office and home desktop PCs that need a reliable 750 W power source
Mid-range gaming or creative workstations with discrete graphics and multiple drives
System upgrades where an ATX 24-pin connector and compact PSU form factor are required

How to use
Power off the PC and disconnect it from mains before installing the ASRock PRO-750B. Mount the PSU into a compatible ATX case bay and secure it with screws. Connect the 24-pin ATX cable to the motherboard main power socket and attach SATA power cables to storage drives as needed using the supplied lengths for convenient routing. Ensure the native 12V 2x6 PCIe connectors are used for compatible graphics cards, matching connector orientation and verifying the dual-color indicators for a secure fit. After all internal connections are made, reconnect mains power and power on the system to verify stable operation.
Usage recommendations
Install the power supply in a case with adequate airflow and keep vents unblocked. Use the provided cable lengths to minimize tension on connectors and arrange cables to maintain unobstructed airflow. For systems with high power peaks or multiple high-consumption components, confirm total system draw remains within the 750 W rating and allow for headroom to ensure longevity and thermal stability.
