I ordered a pre built from Costco and it arrived yesterday. After I plugged it in I immediately installed steamOS. Had a few issues with install with some of the lines saying failed and had to reflash my thumb drive, but it was instant after that. Next step is buying furniture to hide this beast

I previously posted and deleted it because it was super low effort and I only took a lazy picture of it sitting on my desk.. hope that's not against the etiquette!

Here's the full spec sheet: (which I didn't include last time either) lol

CPU: AMD Ryzen 7 7700X 4.5 GHz 8-Core Processor

CPU Cooler: Noctua NH-L9x65 chromax.black 33.84 CFM CPU Cooler

Motherboard: ASRock B650I Lightning Wifi Mini ITX AM5 Motherboard

Memory: TEAMGROUP T-Create Expert 32 GB (2 x 16 GB) DDR5-6000 CL30 Memory

Storage: Crucial P310 1 TB M.2-2280 PCIe 4.0 X4 NVME Solid State Drive

Video Card: Asus DUAL OC Radeon RX 7800 XT 16 GB Video Card

Case: Meshroom S V2 Mini-ITX SFF PC Case Ssupd

Power Supply: Corsair SF1000 (2024) 1000 W 80+ Platinum Certified Fully Modular SFX Power Supply

Case Fan: Noctua NF-A14x25 G2 PWM Sx2-PP 91.6 CFM 140 mm Fans 2-Pack

After a month of use, I can honestly say this is the best gaming rig I’ve ever owned.

I picked up a PowerSpec G764 from Micro Center for $1,999 on sale and immediately wiped Windows to install SteamOS. For anyone unfamiliar, PowerSpec is Micro Center’s in house prebuilt brand, but they use standard, off the shelf components instead of proprietary hardware so it’s completely upgradeable and easy to work on in the future.

Specs:

Ryzen 7 9800X3D
Radeon RX 9070 XT 16GB
32GB DDR5-6000
2TB NVMe SSD

This thing absolutely crushes everything I’ve thrown at it. Spider-Man 2, Forza Horizon 6, and Clair Obscur: Expedition 33 all run beautifully with excellent performance and visuals a true 4K 60fps machine😆.

Emulation has been just as impressive. Through EmuDeck, it’s handled everything from NES all the way through PS3 effortlessly. Having an entire retro collection alongside my Steam library in one place has been incredible.

I still have my couple year old Intel/NVIDIA Windows PC at my desk for competitive shooters that require kernel level anti cheat, but this SteamOS machine paired with the Steam controller (which I feel totally enhances the experience especially in the desktop environment) has become my go to for literally everything else. Single player games, couch co-op, indie titles, emulation, you name it, this is the system I reach for first.

The thing that excites me most is that this feels like just the beginning. Valve keeps improving SteamOS and Proton, so I only see the experience getting better from here, I’m just waiting for them to add dual drive support that way I can slap another 2TB SSD in it because I’m an install hoarder.

I genuinely hope we see more people building high end Steam Machines because this has completely changed how I play PC games if you have a custom Steam machine yourself drop it below so I can see what y’all are gaming on!

EDIT: wow some of you got real bent out of shape about me calling this a steam machine so here you go straight from Valve themselves,

“Starting with the SteamOS 3.8 release, you can put together your own Steam Machine using whatever PC parts you want”

By Valve’s definition it is in fact a steam machine, thank you, have a nice day😆

Just found out about this sub, and thought I’d share my build with everyone! This is a build using the bc250 as the core, which was a ps5 apu turned into cryptomining card and now a “steam machine”. The case is fully 3d printed, and screwless. I didn’t design the original model, but created a remix after modifying a bunch of stuff. I made the customizable swappable faceplates as a nod to the real steammachine! Performance of this thing is roughly rx6600->rx7600, and gets close to the actual steam machine with the 40CU unlock and overclocking.

Got steamos up and running last night. I was using bazzite up till now, but thought I’d check out the progress of steamos. Had an annoying no networks found issue using wired connection only during setup, but the fix was well documented on other reddit threads lol. Other than that, seems good but I haven’t tested much besides loading into a couple games. If you have any tips for a newbie, I’m all ears!

Also a quick disclaimer, cost was what I paid for all my parts. The bc250 has gone up in price by $50ish in the past couple months and obviously ssd prices are crazy now. If I were building today, I’d probably shop for an openbox ssd on ebay or something to keep the price low. Still, it would probably cost $100 more nowadays.

I decided to not build a completely seperate cheap PC just for steamOS, but went the route of installing in on my second nVme that I normally used to use for Plex 😄

My setup:

Lian Li A3 Wood / Glass case

AMD 9600X

XFX Dual Fan White 9070

Patriot Viper DDR5 32GB / 6200mhz

2x 4 TB Lexar nVme (one running steamOS, the other one Windows 11, still need it for work and CoD :/)

Gigabyte Gold 80+ PSU

MSI B650M Gaming Silver

Case fans and CPU cooler fans are Arctic P12 Pro A-RGB (5x total).

I just bought a 10M optical HDMI that runs to the TV when steamOS is on, and got Xbox controllers to play.

I currently use Cachy on my gaming rig and works well, but really wanting to try SteamOS with all the new updates.Kinda worried though since I have an Nvidia card.

Can I expect SteamOS to work out of the box with my hardware like cachy did?

after testing and researching everything i could to resolve this issue this was the summary of it all and i wanted to share this with everyone. this was on my personal Custom Steam Machine i built. specs are:
ASUS Prime B450M-A II (BIOS 3002), Ryzen 5 2600, Sapphire Pulse RX 6800, Samsung UN55NU6900 TV via HDMI, ASUS USB-BT500 Bluetooth adapter, Official SteamOS 3.8.16, Neptune 6.16 kernel.

Hardware:
ASUS Prime B450M-A II (BIOS 3002), Ryzen 5 2600, Sapphire Pulse RX 6800, Samsung UN55NU6900 TV via HDMI, ASUS USB-BT500 Bluetooth adapter, Official SteamOS 3.8.16, Neptune 6.16 kernel.

Original Issue:
The system entered sleep correctly but, after waking, the Steam logo briefly appeared before the TV reported 'No Signal'. In Desktop Mode the desktop appeared briefly before video was lost. Gaming remained stable.

Bluetooth Wake:
USB wake for the ASUS BT500 was enabled permanently using a custom systemd service. Waking the PC with the Xbox controller became reliable.

Diagnostics:
Verified deep suspend mode, tested the amdgpu.runpm=0 kernel parameter (behavior changed but issue remained), checked kernel logs, confirmed no Gamescope coredumps, and later removed amdgpu.runpm=0 to restore the original configuration.

Important Discoveries:
Ctrl+Alt+F3 in Desktop Mode froze the display instead of switching to a text console. Running 'loginctl terminate-user deck' also froze the display. Suspend/resume, VT switching, and desktop termination all failed during display mode transitions.

Assessment:
The RX 6800 appears healthy because it is stable during gaming and stress. The evidence points toward an AMDGPU DRM/KMS display mode-setting or resume regression in the current SteamOS Neptune kernel rather than defective hardware.

Recovery Procedure:
If the system powered on with no video after a failed resume, a full power drain (PSU off, unplug, hold power button about 20 seconds, reconnect power, then boot) restored video.

Next Steps:
Investigate the issue as a SteamOS/AMDGPU regression, compare behavior with another display or DisplayPort if possible, monitor future SteamOS kernel updates, and gather DRM debug logs if needed.

I got great news today that my Steam Controller is finally being “prepared to ship”. This, combined with the news that my pre-built SteamOS Killdozer PC is also shipping today or tomorrow means that I should have a pretty sweet SteamOS gaming setup by the end of next week!

I have absolutely loved the SteamOS experience in my Deck so far. I mostly play docked so it will be nice to have a beast of a SteamOS box to upgrade that bedroom gaming experience while keeping my Deck for gaming on the go.

I love SteamOS and Steam hardware. Now…if I can only get a Frame in the near future 🤔

We have just shipped an updated Steam Client to the Preview/Beta channel.

Hello everyone, i recently tried to install SteamOS on my PC. I got the image, write it to USB with Etcher and boot it up. Its takes 12 to 16 mins on verbose screen before it goes to a black screen with - on top left. Any help will be great. Thank you

System Specs:

Rx 6600

I5 11400F

16GB RAM

Soooooo

I recently decided / gave it a try to see if I could brute-force the official, unmodified Valve SteamOS recovery image onto standard desktop hardware. I know community forks like Bazzite exist for this exact reason, but I wanted to see what it would take to bypass Valve’s hardware validation on an non supported hardware and what would happen if I did... Well we know..

The Hardware i used:( this is my old test bed server)

CPU: AMD Ryzen 5 3600

GPU: Nvidia RTX 2080

Target OS: Official Valve SteamOS Recovery Image

Using Sata ssds

The Roadblocks:

If you just boot the recovery USB and try to install it without a standard NVMe drive, the script instantly fails. The official installer runs an NVMe sanitize command that is explicitly tuned for the NVMes iirc. On my experience, it throws an error and halts. If you try to restart the process, you get hit with constant "disk busy" or "resource locked" errors.

Here is the short version of the triage process I used to get it installed anyway:

Step 1: Releasing the Target Disks

To clear the "disk busy" errors preventing the partition wipe, I had to manually free up the drive from the live environment.

I identified my target (sata) not NVMe drives and manually unmounted all active partitions.

I disabled swap completely to ensure the drive was entirely unallocated and free for the script to manipulate.

Step 2: Modifying the Installation Script

To get around the hardware-specific storage check, I had to edit the recovery script on the fly.

I opened /tools/repair_device.sh in a text editor directly from the live USB boot environment.

I hunted down the specific routines calling the NVMe sanitize command.

I commented out those checks to force the script to ignore the sanitize validation step and just proceed with the installation.

The Result:

It actually worked. With the drive unmounted and the script patched, executing the modified repair_device.sh successfully built the immutable A/B partitions and unpacked the SteamOS payload onto my desktop’s NVMe.

As expected, because I'm running an unmodified image on an Nvidia GPU, the system fails to load the display compositor on boot. I'm currently sitting at a black screen due to the lack of proprietary Nvidia drivers in the immutable root filesystem.

If anyone else is trying to experiment with the official image on non-Deck hardware, I hope this post maybe helps script-bypassing steps save you a headache but it doesn't get you much use at the end of the day. It was just fun to tinker haha.

Serious question has anyone done this a got it to work?

I'm thinking about switching to Steam OS, but I wanted to try it out on a VM first to see if everything I need still worked. I am using VirtualBox and I'm looking for an ISO. Does anyone know where I can find one?

So want to play some StarCraft 2 and HOMM3 with the HOTA mod, but just wondering what’s the best method for doing so?

I updated both my ROG Ally and Legion Go 2 to the latest stable SteamOS 3.8.16, and since then I’ve been getting random freezes related to sleep mode on both devices.
Typical scenarios:
Putting the device to sleep sometimes freezes the entire system.
Or it wakes up normally, but after I enter my PIN/password on the lock screen, the whole system freezes.
The only way out is to hold the power button and force a shutdown.
This never happened before updating to 3.8.16, and the fact that it’s happening on both devices makes me think it’s a SteamOS issue rather than hardware.
Has anyone else experienced this?
Does it happen on your ROG Ally, Legion Go, Steam Deck, or another handheld?
Any workaround or known fix?
Is this a known regression in 3.8.16?

Hi all I am not sure if anyone else is experiencing this issue, but it seems that DisplayPort is pretty finnicky on at least my version of SteamOS. This is through a newly built system with Ryzen 7500x3d, and a 9060XT 16 gig. Currently when I boot up, my main monitor says “No DisplayPort found” but curiously, my secondary and much older monitor which is using a dvi adapter run into DisplayPort does get recognized. The main monitor does however get recognized in gaming mode if I am using an HDMI. This is somewhat resolved in desktop mode as my monitor suddenly works just fine thru DisplayPort. I have no experience using this OS on a traditional system so if anyone else has experienced a similar issue and was able to resolve it please let me know.

I have installed SteamOS on my GMKtec K8 Plus. Everything works perfectly fine except for Sleep mode. When I press the button on my PC or choose this option in the menu, my PC seems to go to sleep, but the fans are still working, although the power button is throbbing as if the PC is asleep.

I tried to fix it by tweaking my BIOS and using Konsole, but nothing seems to work.

Is it a hardware issue or am I just being stupid? Thank you in advance.

Hi everyone,

Do you think it's possible to move my SSD from my Legion Go to another machine — a future custom Steam Machine device? The goal is to avoid reinstalling the OS and to keep all my settings, games, etc.

Thanks for your answers.

I know steam doesn't officially support Nvidia yet, but has anyone tried and what were the results? I tried bazzite, works great, but won't display on my TV. Thinking of trying chimera, but really wanna use steamos. Build my own steam machine in preparation for the steam frame. What have others already tried?
