The ASUS ROG Thor 1200W Platinum II is an internal PC power supply with 1200 watts of capacity. It converts mains electricity into the voltages the components inside a desktop need, and this one adds a small OLED screen that shows power draw as it happens.
What 80 Plus Platinum means
80 Plus is a certification of efficiency. A supply with the Platinum level has to convert mains power with high efficiency at set load levels, typically 90 per cent or higher at the tested points. Higher efficiency means less energy lost as heat in the unit itself, which helps with temperatures and electricity use. ASUS says the unit is built with 100% Japanese capacitors and other quality components to meet this level.
Why 1200W
A supply's wattage is the maximum load it can deliver. Most gaming PCs need much less than 1200W, but high-end graphics cards and processors can draw a lot at peak. A larger supply also tends to run at a lower share of its capacity, which can keep fan noise down. To size a unit, add up the rated draw of your components and leave a margin, using the component makers' recommendations.
Cooling and noise
A 135mm axial fan with PWM control manages temperatures. PWM lets the fan speed follow the load rather than running at one speed. ROG heatsinks cover the main components on the board, which ASUS says cools temperatures and reduces noise. The listing mentions 0dB operation, which in power supplies usually means the fan stops at low loads; check the manual for the conditions.
ASUS also cites a Lambda A++ certification, which it says confirms the unit works with optimal discretion. Lambda is a noise-level classification, with A++ at the quietest end.
The OLED display
An OLED screen on the supply shows power consumption in real time. This is useful for seeing what your system draws in games compared with idle, and can help you spot unexpected changes.
Lighting
The supply is compatible with Aura Sync lighting, so its effects can be synchronised with other compatible devices.
Size and weight
The unit measures 7.5 x 5.9 x 3.4 in and weighs 5.3 lb. The listing's measurements are the ones to check against your case.
Who it suits
It suits builders of high-end desktops, with powerful graphics cards and overclocked processors, who want an efficient, quiet supply and live power monitoring. For a modest PC, a lower-wattage unit does the job.
What to check before you buy
- Wattage: add up your parts' draw, including future upgrades.
- Connectors: confirm the cables match your graphics card, motherboard and drives. Modular layouts vary.
- Case fit: check that the case accepts the standard ATX form and the unit's length.
- Display visibility: the OLED needs to be visible through your case layout.
- Safety: follow the manual, unplug the PC before opening it, and use only the cables made for this unit.
