Hey guys,

I am looking to upgrade my slimline Lenovo desktop (model MT-M 3306 - G2U). I want to put in a GTX 1050ti, however, I am worried I may need to install a 300W TFX PSU because I don't think that 240W will be enough and I don't really want to risk anything.

My problem is that I don't know how or even IF I am able to upgrade my TFX psu. I searched amazon and there are plenty on there but I don't know if they will fit into my case.

This is the PSU I was considering purchasing: https://www.amazon.com/SilverStone-Technology-Supply-Bronze-TX300/dp/B06XS9YLTL/ref=sr_1_1?s=electronics&ie=UTF8&qid=1499633492&sr=1-1&keywords=tfx+power+supply

If anyone could offer some advice or insight as to the compatibility of TFX PSUs concerning size, amperage/voltage and what not I would appreciate it.

I've seen this question before. Sorry, but the "slim" model PCs (and this includes from Dell and HP) may not have a small form factor sub-300W PSU that is up to standard dimension FTX size. There is no way to know if it will fit in your case since the slimline variants are not designed to meet the -TX standard format.

You'd need to buy a new -TX standard sized case to fit a 300+ watt PSU and put all your components in it to guarantee anything. There are severe downsides to owning the slim models of OEM PCs. This is one of them. I'm not even sure if the motherboard of your PC is -TX standard to transplant (meaning screw holes line up, etc.).

About the only thing you can do is remove your current PSU and check dimensions against the...

About the only thing you can do is remove your current PSU and check dimensions against the one you linked above. Still, that would not guarantee the mounting screws line up with your particular case from Lenovo. Again, this is why there are -TX-class build standards for PSUs, motherboards, and cases.

Thank you for being so informative. I figured there would be some issues using a slim pc but it was the most convenient option for a PC for university. I will look into other options now! Thanks again!
