ANTEC Signature 1300 1300W 80+ Platinum Fully Modular ATX 2.0 Power Supply

The ANTEC Signature 1300 is a 1300-watt fully modular ATX power supply built for enthusiast PC builds and demanding professional workstations. Certified 80 Plus Platinum, it achieves efficiency levels of at least 90% at 20% load, 92% at 50% load, and 89% at 100% load when measured at AC 115V, reducing heat output and lowering energy costs over the long term. At the heart of the Signature 1300 is a PhaseWave design — a server-class full-bridge LLC topology with synchronous rectification on a DC-DC architecture. This delivers tight voltage regulation and low ripple noise across all rails, helping sensitive components operate within stable parameters. The unit is populated entirely with top-grade Japanese capacitors for long-term reliability. Thermal management is handled by a 135 x 135 x 25 mm fluid dynamic bearing (FDB) fan. In Zero RPM mode, the fan remains stationary under light loads, allowing completely silent operation until thermal thresholds require active cooling. This extends both fan life and system acoustics for quieter everyday use. The Signature 1300 supports the OC Link feature, which allows two Signature-series PSUs to operate together in tandem for extremely power-hungry configurations. The CircuitShield protection suite provides eight layers of hardware protection: OCP (over-current), OVP (over-voltage), UVP (under-voltage), SCP (short-circuit), OPP (over-power), OTP (over-temperature), SIP (surge and inrush protection), and NLO (no-load operation). Full modularity means every cable is detachable, giving builders complete control over cable routing and airflow management. The generous connector set supports multi-GPU and storage-heavy configurations. The unit carries international regulatory approvals including CB, CE, FCC, TUV, cTUVus, BSMI, 3C, KC, and RCM.
