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.

| Features | Capacitors and chokes pass demanding tests to achieve Military-grade Certification. Dual ball fan bearings can last up to twice as long as sleeve bearing designs. A protective PCB coating protects against moisture, dust, and extreme temperatures. An 80 Plus Bronze Certification is earned with high-quality components that pass rigorous testing. Axial-tech fan design features a smaller fan hub that facilitates longer blades and a barrier ring that increases downward air pressure. 0dB technology lets you enjoy light gaming in relative silence.
