1300 W ATX 3.1 Power Supply

The ASRock TC-1300T delivers 1300 W of fully modular power built to the ATX 3.1 and PCIe 5.1 specifications. It targets high-end desktop builders who need reliable headroom for demanding graphics cards and multi-core processors. The unit carries 80 PLUS Titanium and Cybenetics Titanium efficiency ratings alongside a Cybenetics A+ noise certification. Japanese capacitors are used throughout for long-term stability.

Native 12V-2x6 Connector with TempGuard

The single specification that decides compatibility is the native 12V-2x6 connector, which supports the PCIe 5.1 235% power excursion requirement. A dual-colour design lets you confirm full insertion at a glance, while an integrated NTC sensor monitors connector temperature and signals the PSU to protect against overheating. This connector replaces older 12VHPWR implementations and is mandatory for current-generation flagship GPUs.

Fully Modular Cabling with iCool Fan Control

Full modularity means you connect only the cables your build requires, reducing clutter and improving airflow inside the case. The 135 mm striped axial FDB fan operates under iCool intelligent control: it remains off at low to medium loads for silent running and spins up only when load or temperature rises. A +5 V Boost switch adds 200 mV to the +5 V rail, maintaining approximately 5.2 V when voltage drop is detected, which helps stability on heavily loaded 5 V circuits.

Questions about this item

How much power can a 1300 W unit actually deliver when a GPU spikes?

The unit is rated to handle up to 235% power excursion, so it can absorb short transients well above its continuous 1300 W rating without shutting down.

What does ATX 3.1 and PCIe 5.1 compliance mean for cable limits?

It includes a native 12V-2x6 connector that supports the higher current demands of modern graphics cards under the latest specification.

Will the 135 mm fan fit a standard ATX case cut-out?

Yes, the 135 mm striped axial FDB fan uses the conventional ATX mounting pattern, so it installs in any case designed for a regular ATX power supply.
