I have a desktop with an I5 and a powersupply of 300w, which is pritty low. And I was wondering if I could use another PSU of 300w that I have lying arround justfor the cpu.
 
300W is fine for CPU, you need more according to what GPU you have. There are 24pun adapters to allow for another PSU to be used but better to use for GPUs if you really need another one instead of getting more powerful one.

Thanks for your quick answer, the problem is that I do not have a GPU that has a connector on it (gtx 1050ti asus). But when i'm gaming my CPU onderclocks itselfs, it's not the temperature i guess (arround 60deg celcius). Now the thing is that i only connect my cpu with a 4pin, so i was wondering if i could use a seccond PSU and use his 4 pin aswell so i have a 8pin.

Get a better power supply not a second one. Linking up two power supplies to run a system takes a bit of work, and is not very safe for the computer.
This is a great one for $50 after rebate, modular so case can be kept neater https://www.newegg.com/Product/Product.aspx?item=N82E16817151095
This is $55 after rebate, newer and more efficient https://www.newegg.com/Product/Product.aspx?Item=N82E16817151204
If you are after the lowest price and don't care as much about the cables, this is good https://www.newegg.com/Product/Product.aspx?Item=N82E16817151226
