FAQs

Q: Why do I need a PSU bay blank?
A: It preserves proper airflow and EMI shielding when a power-supply slot is empty, helping maintain thermal performance and reliability.

Q: Does the blank provide power?
A: No. It is a filler only and does not deliver power.

Q: What does H airflow mean?
A: H indicates the airflow orientation used by certain chassis/PSU configs. The blank should match the chassis’ airflow direction.

Q: Can I operate without blanks?
A: Running without required blanks can disrupt cooling and is not recommended.
