Paragrah and image of the Steam Frame VR headset describing the power needed to run the it. The paragraph :| The headset ships in a special mode that requires plugging into power first. Ensure your power adapter supports a minimum of 27W (45W recommended). After you have plugged it in, press the power button to turn it on, then follow the in headset instructions to get through the initial update. After the headset reboots, log into Steam. |: The image :| Side Steam Frame schematic highlight the charging USB-C port on the battery situated in the back of the headset |:

The image doesn't say it "needs" that much power, only that there is an optional mode, likely for high performance or so, but it will probably have heat issues then.

    I think you're reading into it a little too hard. I don't suspect an optional mode based on what's written there. Those power specs come from the USB Power Delivery 2.0/3.x standards. There's 9 Volt USB PD that can supply 27 Watts at the 3 Amp ceiling, and the next step up is 15 Volt USB PD that can supply 45 Watts at 3 Amps. Since a 45 Watt charger is the one that's recommended, I don't expect heat issues there.

    I am referring to the headline of this post that claims that "Steam Frame needs 27-45W of power to run", which is not at all substantiated by the image shared.

    If the "special mode" is what I think it is, it's just a battery saving method that's also used on the Steam Deck. With that, it requires being plugged in to turn on at all, otherwise it just remains in stasis. After it turns on, it operates normally.

    The recommended adapter specs are most likely just for optimal charging, nothing to do with the stasis mode.

    That sounds interesting. How does it work on the Steam Deck?

    It's not a mode that would be used often as it's purpose is to protect the battery if the Steam Deck is going to be inactive for a long time. Most people will only encounter it when they turn on their Deck the first time, as Valve ships them in that mode. You have to go into the BIOS to activate it, and when you want to use the Deck again, it will only turn on by plugging a charging cable into it.
