750 W ATX power supply

The ASUS TUF GAMING 750B is a non-modular ATX12V unit rated for 750 W of continuous power. It targets PC builders who want a straightforward, fixed-cable supply with a single +12V rail and 80 PLUS Bronze certification.

Suits fixed-cable builds with standard connectors

This model fits systems that can use the full set of attached cables: one 20+4-pin motherboard connector, two 4+4-pin CPU connectors, four 6+2-pin PCIe connectors, eight SATA and four peripheral plugs. Builders who prefer to connect only the cables they need should consider a modular or semi-modular unit instead.

Single +12V rail delivers 62 A

The 62 A rating on the single +12V rail determines whether the unit can support the graphics card and CPU combination you plan to install. Check the combined 12 V current draw of your components against this figure before purchasing.

Questions about this item

How long will the 135mm dual ball bearing fan last before it needs replacement?

Dual ball fan bearings can last up to twice as long as sleeve bearing designs, reducing the likelihood of fan replacement during the unit's service life.

What limits sustained output before protection circuits engage?

The single +12V rail is rated at 62A and the unit carries OPP, OCP and OTP protections that will trip if that limit or thermal thresholds are exceeded.

How much noise and heat does the 750W unit produce when running all day?

0dB Technology keeps the 135mm fan off at low loads for silent operation, while 80 PLUS Bronze efficiency reduces waste heat during continuous use.
