ASUS TUF Gaming 1200W Gold EVO PSU - ATX 3.1, PCIe 5.1
The ASUS TUF Gaming 1200W Gold EVO PSU is a full-tower power supply built for PC builders who need high-wattage, ATX 3.1 and PCIe 5.1 support under demanding or harsh conditions. Military-grade capacitors, a protective PCB coating, and dual-ball bearing fan extend service life well beyond standard units. An 8-year warranty backs the durability claims for long-term builds.
Why this product
Military-grade capacitors for longer life
TUF 5K black metallic capacitors offer a 52% wider temperature tolerance and up to a 2.5× longer lifespan than standard capacitors, reducing the risk of degradation over time.
80 PLUS Gold and Cybenetics Platinum efficiency
Low-ESR capacitors help it achieve both 80 PLUS Gold and Cybenetics Platinum efficiency certifications, reducing wasted heat and power draw under load.
Cybenetics Lambda A− noise rating
It emits less than 30 dB of noise on average, making it one of the quieter options in the high-wattage segment.
ATX 3.1 and PCIe 5.1 ready
It meets ATX 3.1 requirements and supports PCIe 5.1 graphics cards, including power excursions up to three times the rated graphics card power for transient stability.
Dual-ball bearing fan for sustained cooling
A 135 mm fan on a dual-ball bearing setup delivers up to 2× longer fan lifespan compared with sleeve-bearing designs.
8-year warranty and corrosion resistance
The PCB coating withstands up to 95% humidity with salt fog for 240 hours, and the unit handles temperature cycling from −40 °C to 85 °C for 27 cycles — backed by an 8-year warranty.

- Does not support 0 dB fan-stop mode; the fan runs at all times under load.
Best for
- High-end gaming or workstation builds that require 1200 W of sustained output with PCIe 5.1 support for the latest graphics cards.
- Builders in humid or tropical environments who need corrosion resistance — this unit withstands 95% humidity with salt fog for 240 hours.
- Long-term system owners who value an 8-year warranty and components rated for extended lifespan over lower upfront cost.
- Noise-sensitive builds where sub-30 dB average acoustic output is a priority, as certified by Cybenetics Lambda A−.
- Efficiency-focused builders who want both 80 PLUS Gold and Cybenetics Platinum certifications to minimise heat and energy waste.
Trade-offs
- Small form-factor or SFX builds — at 150 × 150 × 86 mm this is a full ATX form-factor unit and will not fit SFX or SFX-L chassis.
- Builders who want a silent standby mode — there is no 0 dB fan-stop feature; the fan is always active.
- Budget-oriented builds that do not need 1200 W — the output capacity and military-grade components carry a cost premium that is unnecessary for mid-range systems.
- Legacy system upgrades that rely on a large number of older Molex peripheral connectors — only three peripheral connectors are included.
The ASUS TUF Gaming 1200W Gold EVO packs military-grade strength, a flagship fan design, and PCB protection for efficient, durable power delivery. The result is a PSU that can reliably fuel your rig for years to come.
