ASUS TUF Gaming 1200W Platinum PSU - ATX 3.1, GaN MOSFET
The ASUS TUF Gaming 1200W Platinum PSU - ATX 3.1, GaN MOSFET is built for builders who need dependable, high-efficiency power delivery for demanding systems. It combines a GaN MOSFET with military-grade components and an 8-year warranty to provide durable, stable performance over the long term.
Why this product
GaN MOSFET for greater efficiency
The GaN MOSFET delivers up to 30% improved power efficiency compared to conventional designs, with faster switching speeds, lower heat generation, and higher voltage resistance suited to demanding workloads.
80 PLUS Platinum and Cybenetics Platinum rated
It holds both 80 PLUS Platinum and Cybenetics Platinum efficiency certifications at 115V and 230V, meaning less energy is wasted as heat during operation.
ATX 3.1 and PCIe 5.1 ready
It meets the ATX 3.1 standard and supports PCIe 5.1 graphics cards, including total power excursions up to twice rated power and GPU excursions up to three times rated power.
Comprehensive protection on every rail
Six protection circuits — OPP, OVP, UVP, SCP, OCP, and OTP — guard connected components against overvoltage, overcurrent, short circuits, and thermal events.
Eight-year warranty coverage
ASUS backs this unit with an 8-year warranty, one of the longer coverage periods available on a consumer PSU.
Fully modular cabling included
The box includes individually sleeved modular cables for the motherboard, CPU, PCIe, SATA, and peripheral connections, keeping cable management tidy without buying extras.

- SKUASU-2458
- EAN4711636489607
- Compatible with ATX 3.1 motherboards and cases accepting a standard ATX PSU (150 × 150 × 86 mm).
- Supports PCIe 5.1 graphics cards via the included 16-pin (12V-2x6) native cable.
- AC input range of 100–240 V covers both North American and international mains voltages.
- SATA and peripheral connectors make it compatible with standard storage drives and accessories.
- Does not include AURA SYNC RGB — there is no lighting on this unit.
- Does not feature 0 dB fan mode — the fan runs continuously without a passive/silent mode.
Best for
- High-end gaming rigs — the 1200 W output and PCIe 5.1 support accommodate current top-tier discrete GPUs with headroom to spare.
- AI development and video editing workstations — GaN MOSFET efficiency and military-grade components suit sustained, heavy compute loads.
- Builders who keep systems long-term — the 8-year warranty and MTBF rated above 120,000 hours at 40 °C support multi-year ownership.
- International use — the 100–240 V AC input range means it works on both 115 V and 230 V mains without an external converter.
- Cable-management-conscious builders — all cables are modular and individually sleeved, so only the connectors needed have to be routed.
Trade-offs
- Noise-sensitive or near-silent builds — this unit has no 0 dB or passive fan mode, so the fan operates at all load levels.
- RGB-focused builds — AURA SYNC is explicitly absent; the unit has no addressable lighting.
- Compact ITX or SFX cases — at 150 × 150 × 86 mm it is a full ATX form factor and will not fit SFX or SFX-L bays.
- Budget-conscious builds — GaN MOSFET technology and an 8-year warranty position this at the higher end of the PSU market.
