Hello - Let me just briefly introduce myself.
My name is Simon, I'm from Denmark so if my English is a bit rusty, I'm sorry.
I am a master of science in public health student, I have NO electronic experience, beyond my basic knowledge and passion.
I'm working on a mod for a Apple Macbook Pro 13", where I attach a real desktop graphics card to it, via thunderbolt 2.0.
I use a Dell DA-2 12v 18a power supply to power the PCB for the TB2 connection, as well the graphics card. Sometimes the powersupply reaches 210watt usage, and the card gets unstable.
I would here like to ask you if it would be possible to find a 12v capacitor to provide some extra juice when the wattage peaks in high spikes.
I'm thinking about using a simple capacitor for auto hifi, such as this one
www.ebay.com/itm/Bullz-Audio-2200W-...er-Farad-Capacitor-Cap-BCAP-2-2-/171412141292
Would it be able to handle the stress ?
And how would connect it ?
This is my "eGPU" solution so far:
The eGPU uses a XT60 connector to the power supply, and I hope I could add the capacitor between the PSU and eGPU.
I've made a --- sketch in paint here, and am I on the right path to make this possible ?
And I know I could use another PSU, however, I want to use the Dell da-2 if possible.
