GaN MOSFET

The ROG Strix Platinum PSU boasts innovative GaN MOSFET that delivers superior power efficiency by up to 30%, resulting in lower energy waste. Plus, the smaller size of GaN MOSFET allows for a more organized internal layout within the PSU. This optimized design provides space for larger heatsinks and enhanced airflow, improving heat dissipation within the PSU.

Voltage Sensing Mode

"GPU-FIRST" Voltage Sensing

with patented-intelligent voltage stabilizer

Activate the "GPU-FIRST" voltage sensing by connecting the IVS cable. This innovative feature enhances voltage stability by up to 45%, even during demanding gaming sessions and overclocking scenarios. If you prefer conventional CPU-focused voltage sensing, just simply disconnect the IVS cable. With this advanced technology, you can experience smooth and consistent gameplay.

Disclaimer: The "GPU-First" intelligent voltage stabilizer is designed exclusively for 16-pin PCIe power cables. This feature is not available for 8-pin PCIe power cables.

Next Gen Gaming PC? RTX 5080 ASTRAL & 9800X3D Build

BUILDING THE ULTIMATE GAMING SETUP!

In order to power it all, we didn't skimp on the power supply - Asus ROG Strix 1200 W with a platinum certificate. I would have taken a kilowatt, it would have been enough here, but I want it to be with a strong margin

In games I tested it with a 1200W Asus power supply, with 5080 like cards it is vital, in the case of video cards like 5070 a 750W power supply would be enough for you

Good thing that ASUS has a good line of components, you don't have to invent to experiment

It is just magnificent [...] I am very happy with the result !

A premium-class PSU for this hardware.

When you have manufacturers like Asus with all these ROG ranges for example which offer a 10-year warranty, you can well imagine that a 10-year warranty means they are sure of their products

Fortunately, in combination with the new ASUS 1200W power supply, everything was fine. I have to commend ASUS from several points of view, their RTX 5090 design has an advantage precisely in that naughty power section. We can monitor individual pins and the card is supposed to have protection against too high a current and should prevent damage.

Furthermore, this power supply also meets the latest ATX 3.1 / PCIe 5.1 standards, which, along with the 10-year warranty from the manufacturer, gives me almost certainty of its long-term use.
