Powering a 750 ti

[Yung Lead]

Hi there,

 

For my current project I'm trying to convert a laptop into a desktop and I want to make the performance better without spending a lot of money,

so I am not looking to buy another laptop for this and one of my friends gave me his 750ti. I am using External Independent Video Card PCI-E 16X slot for the 750 ti.

It takes in dc power so I am wondering if my 19v with 3.95amp laptop charger would be enough to power the 750 ti, also heard the 750 ti takes up less than 80 watts.

 

Thanks for the help!

Should probably just buy like any decent PSU and hook it up to whatever that PCI-e thing uses for power

But really maybe just buy an APU rig soonish?

oh nvm you have a desktop PC already

Most likely your laptop PSU can't power it, because it's an extra 75W or so, they make like 200W pico PSUs that are the same size as laptop PSUs, but they don't have the connections you need.

 

But if you're making it a desktop what does it matter that there's an extra PSU powering the GPU?

I have another laptop charger for the expansion card to power the gpu but idk if its enough to power it cause it takes in dc power. And im making the expansion card apart of my custom case and the regular PSU would make the case bigger.

The card adapter takes 12v, not 19.5v.  If you hook the laptop power adapter to it you will fry the GPU and maybe the laptop.

oh lmao, so if i use a 12v charger would it work?

12v 7A+ (~85w) needed.  I would aim for 100w (8-9A).
