A:AnswerHello there! If you're having Wi-Fi issues with the PC, it could be related to the drivers needing an update or not using the included antennae accessory. If you're still having issues, we recommend reaching out to iBUYPOWER Tech Support as soon as you're able for troubleshooting help.

A:AnswerHello! Unfortunately, the default PSU included in this PC is a 600 Watt and not a 750 Watt that's recommended for an RTX 4080TI. If you have plans to upgrade your GPU, you'll likely need to upgrade your PSU as well.
