Power supply Asrock SL-750G 750W 80 Plus Gold PSU ATX 3.1, PCIe 5.1

Asrock SL-750G is a 750W modular power supply from the mid-high range, aimed at modern gaming and workstation configurations with more serious GPUs. The 80+ Gold certification and declared efficiency of 90% mean less heat loss and more stable voltages under load. Thanks to ATX 3.0/3.1 and PCIe Gen 5.0/5.1 support, you are ready for current and future graphics cards with the new standard. The combination of modular design and 135mm FDB fan gives you quieter operation and cleaner internal assembly.

What you get is a power supply with a real focus on modern GPU standards and flexible connectivity. The PCI-E Gen5 12VHPWR connector allows you to connect current generation graphics cards directly, without the need for adapters, while the three PCI-Express 6+2 pin connectors cover classic high-end models. With 9 SATA and 3 Molex connectors, you can easily build a system with many SSDs/HDDs, fans, or controllers, without worrying about a shortage of power lines. The modular design means you only connect the necessary cables, which improves airflow and makes cable management easier. Active PFC and Gold efficiency help the power supply maintain more stable voltages under varying loads – typical for gaming and mixed-use scenarios.

• Power 750W – sufficient for strong gaming and workstation configurations with modern mid-range to high-end GPUs and plenty of storage.
• 80+ Gold certification and around 90% efficiency – lower losses, less heat, and quieter operation under prolonged load.
• ATX 3.0/3.1 with PCIe Gen 5.0/5.1 support – compatibility with the new generation of graphics cards and better preparation for future upgrades.
• PCI-E Gen5 12VHPWR x1 + PCI-Express 6+2 pin x3 – full coverage for both new and older high-end GPU solutions.
• 9 x SATA and 3 x Molex connectors – convenience for systems with many SSDs/HDDs, fan hubs, and peripherals, without the need for splitters.
• Modular design – you connect only the necessary cables for a cleaner interior, better airflow, and easier installation.
• 135mm FDB fan – longer life and quieter operation compared to standard bearings, especially under partial load.
• Active PFC and input 100–240 VAC – stable operation over a wide range of mains voltage, suitable for more unstable electrical installations.

Who is this model suitable for? For gamers and enthusiasts who want an ATX 3.1 power supply with 12VHPWR for modern GPUs, without jumping into extreme watts. It is also suitable for those planning multi-drive systems or a more serious upgrade cycle. If you are aiming for a super budget build with low-power components, some of its capabilities simply won't be utilized.

Asrock SL-750G impresses mainly with the balance between 750W power, 80+ Gold efficiency, and full ATX 3.1 / PCIe Gen5 support – a practical solution if you want a power supply „ready for the next graphics card“ without unnecessary marketing extras.
