Antec V3 user manual Congratulations on your purchase of the Antec Twelve Hundred

Congratulations on your purchase of the Antec Twelve Hundred V3.

Antec’s Twelve Hundred V3 gaming case combines maximum performance, cooling and compatibility in a full-tower package. Thirteen drive bays, space for graphics cards as large as 17.5,” a CPU cutout, an internal 2.5” SSD drive mount and newly integrated USB 3.0 round off a robust foundation for your components. The Twelve Hundred V3 features a top Big Boy 200™ blue LED cooling fan, two rear blue LED 120 mm fans and three front blue LED 120 mm fans. Apart from standard size power supplies, the Twelve Hundred V3 can accommodate Antec’s CPX form factor PSUs.

The Twelve Hundred V3 comes without a power supply. Make sure you choose a power supply that is compatible with your computer components and has a long enough power harness to reach your motherboard and peripheral devices. We recommend our High Current Gamer, High Current Pro or CP power supplies for the latest ATX specification compliance, broad compatibility, and power savings capability.

At Antec, we continually refine and improve our products to ensure the highest quality. It’s possible that your new case will differ slightly from the descriptions in this manual. This isn’t a problem; it’s simply an improvement. As of the date of publication, all features, descriptions, and illustrations in this manual are correct.

Disclaimer: This manual is not designed to cover CPU, RAM, or expansion card installation. Please consult the motherboard manual for specific mounting instructions and troubleshooting. Before proceeding, check the manual for your CPU cooler to find out if there are steps you must do before installing the motherboard.
