I think you may have an unrealistic idea of how much power low or mid-range gaming PC’s use. Only at the very top-end of PC’s with extreme overclocked components pushed to the limit would you come near 1000w (a $3000 Nvidia GTX 5090 graphics card can use 575w, as an example).
The Steam Machine uses effectively a laptop CPU (35W TDP) that’ll likely use 40 to 50w max, and the GPU is also a beefed up laptop GPU with a 110W TDP (it’ll probably peak at 140 to 150w, I’m guessing).
Overall it’ll probably idle at 10 or 15w, and likely use around 70w under average gaming, or 150 to 200w when pushed hard.
The Steamdeck is certainly still more power efficient (it peaks at 25w when pushed hard), and if you find that it’s powerful enough for the games you play, there’s not much reason to consider getting anything else. But the Steam Machine will be pretty power efficient for a desktop. It kinda has to be, since it only has a single fan for cooling.
I doubt it would be feasible to replace the power supply with something that takes 12v DC
All PC’s run off a power supply that inverts 120/220v AC to 3.3V 5V, and 12V DC for the internal components to run off of. Your Steamdeck charger is no different from the power supply inside a desktop PC, it’s just smaller and put in an external shell.
Unless by 12v DC, you mean you’re charging your Steamdeck with solar panels or from batteries directly, in which case, you could use an Inverter to power the Steam Machine.
Well that’s great news, thanks. Yeah most of my system is 12v, running off a big ole lithium battery which is charged by solar panels. I can do 220v via a 1000w inverter, sounds like this could run a steam machine. Food for thought! Though I’m kinda interested in the steam frame too, waiting to see what the prices are like.
The funny thing is, those power bricks you plug into the AC outlet convert that back to DC and various voltages (including 12v).
I’ve wondered for a while if we’ll start seeing more DC input electronics designed for setups like yours because there’s efficiency losses for both the DC -> AC step and the AC -> DC step.
