ASUS TUF Gaming 1000W Gold PSU: features, specs and who it suits

The ASUS TUF Gaming 1000W Gold (model 90YE00S1-B0NA00) is an internal power supply unit, or PSU, for desktop PCs. It converts mains electricity into the steady low-voltage power that a processor, graphics card and drives need. ASUS positions it as an efficient, resilient unit designed for the long term, with a modular cable design and ATX 3.0 compatibility.

What 1,000 watts means in practice

The wattage is the maximum a PSU can deliver, not what a PC draws all the time. Most systems use only a fraction of it during everyday work and spike higher under gaming or rendering loads. A 1000W unit typically gives headroom for a powerful graphics card plus a high-end processor, and it can leave room for later upgrades. Add up the rated power of your parts and leave a margin rather than aiming to use the whole figure.

80 Plus Gold and efficiency

80 Plus is a testing programme that rates how efficiently a PSU converts AC power to DC at set load levels. Gold sits above Bronze and Silver and below Platinum and Titanium. In general, higher efficiency means less energy turned into heat inside the case, which can help with noise and cooling. ASUS says the Gold certification reflects Japanese capacitors and other premium components.

ATX 3.0 compatibility

ATX 3.0 is a newer power supply standard, written with modern graphics cards in mind. These cards can produce short power spikes well above their average draw, and the standard sets out how a PSU should cope with them. It is also associated with a 12-volt high-power connector for graphics cards. Check which power connector your card uses, and what cable comes with the PSU, before you plan the build.

Fans, coating and cables

ASUS fits dual ball bearing axial fans and says they last twice as long as plain bearing fans. The axial fans have a smaller hub, larger blades and a ring that, according to ASUS, improves downward air pressure. The circuit board has a protective coating that ASUS says guards against moisture, dust and extreme temperatures.

The cable design is modular, so you connect only the cables your build needs. That usually leaves less clutter in the case and better airflow. ASUS describes the cables as adjustable and engraved for a neat setup.

Size and weight

ASUS lists the unit at 2.2 lb (about 1 kg). The listing's dimensions look like packaging figures, so check the PSU's real length against your case's published PSU clearance.

Who it suits

It suits people building or upgrading a desktop with a high-wattage graphics card, or anyone who wants spare capacity for future parts. It is less necessary for a modest office PC, which needs far less power.

What to check before you buy

• Total power need: add up the rated power of your processor, graphics card and drives, then leave a margin.
• Graphics card connector: confirm the connector your card needs and that the cables supplied match it.
• Case fit: check your case's maximum PSU length and mounting layout.
• Cable count: make sure there are enough connectors for your drives, fans and other parts.
• Mains supply: follow the manual and local electrical codes for installation, and switch off and unplug the PC before working inside it.

The short version

• A 1000W modular ATX power supply, model 90YE00S1-B0NA00, from ASUS's TUF Gaming line.
• 80 Plus Gold efficiency certification and ATX 3.0 compatibility.
• Dual ball bearing axial fans and a protective coating on the circuit board.
• Adjustable engraved cables for tidy builds.
• Weighs 2.2 lb; check case clearance and connector needs first.
