1300W ATX Titanium PSU

The Seasonic PRIME TX-1300 is a 1300W ATX power supply with 80 PLUS Titanium certification and a fully modular cable design. It uses a single +12V rail and includes a 135 mm Fluid Dynamic Bearing fan. The unit measures 210 mm in length and carries a 12 year manufacturer warranty.

Two 16 pin PCIe cables

The bundle provides two 12VHPWR cables rated for 750 mm, eight 6+2 pin PCIe cables and three 4+4 pin EPS cables. This connector mix supports multiple high-end graphics cards and multi-CPU motherboards without adapters. All cables are PVC embossed for easier routing.

210 mm case clearance

Verify that your chassis allows at least 210 mm for the power supply depth before ordering. Ensure the motherboard has the required 24 pin ATX and 8 pin EPS sockets. Confirm your graphics cards use 6+2 pin or 12VHPWR connectors.

Questions about this item

Will the 135 mm fluid dynamic bearing fan need replacement during the 12 year warranty period?

The fan is rated for over 150,000 hours MTBF, which is well beyond the 12 year warranty, so replacement within that period is unlikely.

At sustained 1300 W output, which protection limit activates first?

Over-power protection (OPP) triggers if the load exceeds 1300 W, while over-temperature protection (OTP) engages if internal components overheat during prolonged full-load operation.

How loud and hot does the unit get when running at full load all day?

The premium hybrid fan control keeps the 135 mm FDB fan at low RPM until higher temperatures are reached, so noise stays minimal and heat is exhausted efficiently through the 210 mm deep chassis.
