Frequently Asked Questions

Is the ASRock Steel Legend 650W enough for an RTX 4070?

Yes, the 650W power supply is sufficient for an RTX 4070, which typically requires a 600W PSU. It also provides a 12VHPWR connector for direct connection.

Does this PSU support the latest ATX 3.0 standard?

While it includes a 12VHPWR connector for PCIe 5.0 GPUs, it is not fully ATX 3.0 compliant. It uses the standard ATX12V/EPS12V design, but it can still power modern components.

What is the fan noise level under load?

The 120mm FDB fan operates quietly, and with Zero RPM Mode, the fan stops completely under low loads. Under heavy loads, the fan spins up but remains relatively quiet, with noise levels around 25 dBA.
