Valve Announces Hardware Specs on Steam Machines – Intel CPU and NVIDIA GPU

Greg Coomer from Valve announced for the very first time the hardware details that will be used on the first 300 prototype Steam Machines the company will be shipping out later this year. The prototype machine is a high-end, high-performance box, built out of off-the-shelf PC parts. It is also fully upgradable, allowing any user to swap out the GPU, hard drive, CPU, even the motherboard if you really want to. Apart from the custom enclosure, anyone can go and build exactly the same machine by shopping for components and assembling it themselves. The only thing that Valve will be designing is the chassis, but they will be sharing the source CAD files for the enclosure, in the event that someone wants to make or modify it on their own!

It should also be noted that Valve doesn’t want gamers to believe that buying a Steam Machine is the only way to get the ideal living room experience. many gamers will want to use the PC they already have and that is entirely possible thanks to SteamOS. “The prototype we’re talking about here is not meant to replace that,” Coomer says in a blog post made this morning. “Many of those users would like to have a way to bridge the gap into the living room without giving up their existing hardware and without spending lots of money. We think that’s a great goal, and we’re working on ways to use our in-home streaming technology to accomplish it – we’ll talk more about that in the future.”

Hardware Specs on The First 300 Valve Steam Machine Prototypes:

GPU: some units with NVIDIA Titan, some GTX780, some GTX760, and some GTX660
CPU: some boxes with Intel Core  i7-4770, some Core  i5-4570, and some Core i3
RAM: 16GB DDR3-1600 (CPU), 3GB DDR5 (GPU)
Storage: 1TB/8GB Hybrid SSHD
Power Supply: Internal 450w 80Plus Gold
Dimensions: approx. 12 x 12.4 x 2.9 in high

It’s a shock to see that a 450W power supply used for something that could be running an NVIDIA GeForce GTX Titan graphics card, but it goes to show you what you can get away with when using high-quality components! The NVIDIA GeForce GTX Titan has a suggested PSU rating of 600W in case anyone is wondering.

    wtf those cards with 450w???

    Looks like no upgrade capabilities or disk expansion, or even dvd drive. Titan+i7 477- peaks about 350W unless you run catzilla or another massive bench, so the 450W should be able to run a titan WITHOUT overclocking anything and with only the base drive. If you tried to put 5 drives in there like my computer has (and even my HTPC supports), you would easily cross 450W if the drives start up when playing a game. They should have at least considered a 550W PSU instead, for a bit head room and better efficiency.

      This is taken from their [Valve's] FAQ on the announcement page:

      ‘Will I be able to build my own box to run SteamOS?
      Yes.

      Can I hack this box? Run another OS? Change the hardware? Install my own software? Use it to build a robot?
      Sure.

      Can I download the OS to try it out?
      You will be able to download it (including the source code, if you’re into that) but not yet.’

      So the possibilities are far from limited, I’m sure the PSU can be upgraded if needed, or you can build your own “box” altogether.

        Your response is like saying you can bake apple pie when someone complains that the apple has a worm. We all know you can build your own box, but the complaint was about THEIR box specs.

        And considering the box is only 3″ by a square foot, the only way you are getting a TITAN in there is laying it on the side of a mITX with the port at 90 degrees. The space left over is pretty much only good for a 2.5″ drive (likely STBD1000400) and power supply (ST45SF-G sounds like our man). You might be able to fit in one more ssd/7mm HDD, but that’s about as much upgrading as you can get done, since 450W is the largest SFX supply out there. Maybe down the line there will be upgrade graphics, perhaps even using AMD, but it’s a console alright, practically nothing you can do to upgrade.

          If you don’t like it, don’t buy it. Considering this is Valve’s first attempt for a console (I would argue it’s design warrants a different label), it has a lot to commend about it, that and the OS + controller.

          Valve is trying to break down the barriers between console and PC gaming, for that, I applaud them. (Though, nothing could make me relieve my PC from its gaming duties.)
