Gaming upgrade/Low-profile GPU for PicoPSU-powered i3-HTPC

I want to upgrade my HTPC to allow for some gaming. Currently I'm using the i3-3225's onboard Intel HD4000 graphics.

Besides the general question regarding a suitable graphics card there are a couple of restrictions due to the general system design which make the buying process difficult for me:

1. CPU: I'm currently running an i3-3225. Is that enough for gaming if I add a dGPU? Or do I also need to upgrade the CPU?
2. PSU: I'm currently using a picoPSU-160-XT with 192W external PSU. There is already a Digital Devices DuoFlex CT TV tuner card in the system. So would there be enough power for the additional graphics card (and, if needed, an i5 CPU)?
3. Form factor/Heat/Noise: Being a HTPC, the case is rather small, size of an AV receiver. Therefore I can only use low-profile PCI cards. Furthermore the system runs almost fanless (besides a Big Shuriken Rev. B CPU cooler). There's a big hole next to the PCI slots though (where actually an internal SFX form factor PSU would go) which I could possibly use to place a case fan.

So is a gaming upgrade possible?

I would save your money for a new PC, but it matters what games your going to be playing. 192w Power supply is very minimal, but it only uses 66w under load, but if you were going to buy a graphics card like the 7770 it would need at least a 450W power supply.

you could try getting a better power supply, but I think it would be better to look on ebay, or your local store for refurbished computers for cheap.


I guess this is what your PC looks like.

Thanks for your replies! The case is this MS Tech MC-1200 case:

My current build looks pretty much the same except having a bigger CPU cooler and where in the picture the PSU is, there is just a big hole in my case.

So I understand I gonna need a new PSU and can't use my PicoPSU anymore. Now I'm wondering how loud and hot my case is going to get with eg. a 450 W PSU? Are there any decent SFX form factor 450 W PSUs that are reasonably quit and don't make my case get hot like crazy? I'm specifically worried about the PSU then sitting directly next to where the new GPU would be sitting (in the 2nd picture you can see a TV tuner card which is where the PCI slots are and where a low profile GPU would be).

Do I also need more CPU horsepower? I'm interested in games like Far Cry 4, GTA, Fifa/PES, etc.
