CyberPowerPC doesn't have an official page on their website for sponsorships. Instead, they request you email them the following:
- Tell them about yourself
- Include all your social media accounts and their respective follower count
- Explain how you can promote CyberPowerPC
In essence, you need to have a decent following on Twitch, YouTube, or Twitter to be considered. If you do, tell them how you can add value to their brand. If you can't, chances are you won't make the cut.
Email email@example.com to be considered. See their list of sponsored streamers here.
