Frequently Asked Questions
Q: Does this PSU support modern GPUs with 12VHPWR?
A: Yes, it includes a native PCIe 5.1 (12VHPWR) connector, so you don't need adapters for compatible graphics cards.
Q: Is the fan silent at full load?
A: Under light to moderate load the fan is very quiet. Under full load it increases RPM but remains within safe acoustic limits thanks to a smart control curve.
