ATX 3.1 & PCIe 5.1 750 W unit

The ASRock SL-750G is a fully modular power supply rated at 750 W. It meets the ATX 3.1 and PCIe 5.1 specifications for modern platforms. The unit carries 80 PLUS Gold and Cybenetics Platinum efficiency certifications. It is built with 100 % Japanese capacitors for long-term reliability.

Check 12 V-2x6 and EPS needs

Verify that your graphics card uses the 12 V-2x6 connector, as the PSU provides one native 16-pin cable. Confirm your motherboard requires two EPS 12 V (4+4 pin) connectors, both of which are included. Ensure your case can accommodate a 150 mm deep ATX power supply. The SATA and peripheral counts should match your drive and accessory layout.

Fits mainstream builds with quiet cooling

The 135 mm striped axial FDB fan supports iCool intelligent control, stopping at low load for near-silent operation. Cybenetics Lambda A+ certification confirms average noise below 20 dB. Full modular cabling reduces clutter and improves airflow. The compact depth frees space behind the motherboard tray for cable routing.

Questions about this item

What cables come in the box and which ones do I need to buy separately?

The box includes a 24-pin motherboard cable, two EPS 12V CPU cables (4+4 pin), one native 12V-2x6 PCIe 5.1 cable, two 6+2-pin PCIe cables, three 4-pin peripheral cables and nine SATA power cables. All are modular so you connect only what you need.

How do I decide between the 650 W, 750 W, 850 W and 1000 W versions?

Choose 750 W for a single high-end GPU and modern CPU; step up to 850 W or 1000 W if you plan dual GPUs or extreme overclocking, or drop to 650 W for mid-range builds.

What does the Cybenetics Lambda A+ rating mean for everyday noise?

The unit averages below 20 dB in typical use, so the 135 mm FDB fan is practically inaudible at low and medium loads, and iCool mode can keep it stopped entirely until the load rises.
