1000 W ATX 3.0 power supply

The ASUS TUF-GAMING-1000G delivers 1000 W of fully modular power for high-end desktop builds. It meets the ATX 3.0 specification and carries 80 PLUS Gold efficiency certification. Military-grade capacitors and chokes are validated through extended MTBF, drop, vibration, temperature and salt-fog testing. A protective PCB coating guards against moisture, dust and extreme temperatures.

ATX 3.0 connector limits

The unit includes one 16-pin PCIe Gen 5 cable rated for up to 600 W delivery to compatible graphics cards. Four additional 8-pin PCIe connectors are provided via two 1-to-1 cables and one 1-to-2 cable. Two CPU 4+4-pin cables, five SATA connectors and four peripheral connectors complete the output set. All cables are fully modular with etched sleeves for cleaner routing.

Clearance and voltage check

The power supply measures 150 mm in length, 150 mm in width and 86 mm in height, weighing 2.48 kg. Verify that your case can accommodate these dimensions before ordering. Confirm that your mains supply falls within the 100–240 V input range. Ensure your motherboard uses a standard 20+4-pin main connector and that your CPU requires no more than the two provided 4+4-pin headers.
