I would like to build a small PC as a replacement for a laptop and would like to install a battery in order to be able to work away from an electrical outlet.
Thought a laptop battery.
I want to build a Ryzen 5 2600 and probably a GTX 980Ti into the PC.
I'll have to come up with something myself, but maybe someone is familiar with it or can advise against it.
That won't be possible.
There's a reason notebook computers don't share the same CPU and GPU and RAM. The power consumption of a mid-range PC is still higher than that of a high-end notebook. In addition, PCs need certain voltages for the components. You can't do that with a battery.
The batteries will then be larger than the PC. 2x car battery then a converter and charger etc.
Thought a laptop battery.
What is such a laptop battery. Vlt 140Wh, then it's quite a big…
Under load the GTX has something around 200W plus CPU etc… So let's estimate 280W total… Then the battery would be flat after 30 minutes without paying attention to the discharge characteristic… But the usage time is actually much shorter… You also have power losses due to voltage converters, since a PC needs 12V, 5V, 3.3V, -12V… So just one battery is not enough to power a desktop. Notebooks already have the corresponding voltage converter circuits on the mainboard…
I added it up according to your hardware requirements, you need at least 450W here, which means that you, if you want to need that with a low-voltage switched-mode power supply with 12V input voltage around 40A (there are actually such), a modern car The battery would be empty in 2 hours
Which laptop batteries pack the 300-400 watts that the system will draw, not to mention the battery life?
