Built for mid-range gaming builds

The ASUS TUF GAMING 450B is a 450 W ATX12V power supply with a single +12 V rail and 80 PLUS Bronze certification. A 135 mm dual ball bearing fan uses Axial-tech design and 0dB technology to stay quiet under light loads. Non-modular cabling includes a 20+4 pin main connector, one 4+4 pin CPU lead, two 6+2 pin PCIe plugs, five SATA and four peripheral connectors.

Suits entry-level systems, not high-end GPUs

This unit fits builds that draw up to 450 W and need only two PCIe power connectors. The 150 mm length works in most standard cases. Systems requiring more than two graphics power cables, modular cables or a higher wattage ceiling should consider a larger model.

450 W maximum power decides fit

The 450 W rating sets the hard limit for total system draw. If your components combined exceed this figure, the supply cannot deliver stable power and a higher-rated unit is required.
