Q: 9. Is this adequate for a gaming PC rig?

A: Thank you for your interest in our products. Unfortunately the BN450M is likely too small for a gaming PC. The BN450M would only support 255 watts of equipment connected to it so it will likely become overloaded. I would just confirm how large the power supply is in the PC and make sure the UPS would support the PC. Likely you will need something from our BackUPS Pro line like the BX1000M.
