ASUS TUF Gaming 1000W Gold White Edition PSU: specs and who it suits

The ASUS TUF Gaming 1000W Gold White Edition (TUF-GAMING-1000G-WH) is an ATX power supply unit, the part of a desktop PC that converts wall power into the voltages the components need. With 1000W of output and an ATX 3.0 design, it is aimed at gaming builds with powerful graphics cards.

What 1000W means in a PC

The wattage is the total power the unit can deliver. ASUS lists a total output of 1000W, most of it on the +12V rail, which feeds the processor and graphics card. The listing gives a 12V maximum of 83.3A, a combined 1000W on that rail, with 25A each on +3.3V and +5V, a combined 130W on those two, plus smaller -12V and +5Vsb outputs.

A higher wattage than a system needs leaves headroom for upgrades and power spikes. Add up the components' rated power use, then choose a unit with margin above that, as the component makers recommend.

ATX 3.0

ATX 3.0 is an updated power supply standard designed for the sharp, short power spikes modern graphics cards can produce. Listings for ATX 3.0 units typically include a 12VHPWR connector for newer graphics cards. The listing here confirms ATX 3.0 support but doesn't detail the cables, so confirm the connector set in the box against your graphics card.

80 Plus Gold efficiency

The 80 Plus Gold certification means the unit meets a defined efficiency level at typical loads, so less of the power drawn from the wall is lost as heat. ASUS says the certification results from Japanese capacitors and other premium components. Higher efficiency generally means less heat and less fan noise for the same output.

Fan and cooling

The listing describes two fan features:

• Double ball bearings, which ASUS says can last twice as long as sleeve bearing designs.
• Axial-tech fan design, with a smaller hub allowing longer blades and a barrier ring to increase downward air pressure.

The fan helps move air through a case. Mounting orientation and airflow depend on the case, so follow the manual.

Protections and input range

ASUS lists the protection features OPP, OVP, UVP, SCP, OCP and OTP: over-power, over-voltage, under-voltage, short-circuit, over-current and over-temperature protection. These cut the output if conditions go outside safe limits. The unit uses active PFC (power factor correction), accepts 100-240V AC input and is listed as RoHS compliant.

Size and warranty

The PSU is 150 x 150 x 86 mm, which is standard ATX size, and weighs 5.5 lb. The listing mentions a 24-month manufacturer's warranty. Check the current terms for your region with ASUS.

Who it suits

It suits builders putting together or upgrading a high-power gaming or workstation PC, and anyone who wants a white component for a light-coloured build.

What to check before you buy

• Total power need: add up your processor and graphics card requirements.
• Connectors: confirm the cables match your graphics card, motherboard and drives.
• Case fit: check your case supports a standard ATX unit and its cable space.
• Colour: the white finish suits matching builds.
• Installation: switch off and unplug the PC first, and follow the manual and local electrical codes. If you're unsure, ask a qualified technician.
