I have an all-in-one PC that needs a power supply of 19V, but the only one I have available is 19.5V. Is it okay to use this slightly higher voltage? I want to know if it's safe or if I should just buy a new power supply, especially since I don't even know if the computer will work properly with it.

Generally, a 5% voltage variance is considered acceptable. For 19V, that’s about 0.95V, so your 19.5V should be within spec. Just make sure it can handle the wattage and fits the connector!
No way, it’s definitely not safe. Stick with what’s recommended, no exceptions.
It’s most likely fine considering it’s within 5% tolerance, but just to be safe, I’d recommend getting a new PSU specifically rated for your PC.
I wouldn't risk it. Using mismatched voltage could lead to issues down the line. Better to buy the correct power supply and avoid potential headaches!
.5V difference is usually not a big deal at all. Just ensure that the amps match or exceed your old power supply's rating and you should be good to go!
Using a 19.5V power supply might work, but it’s a bit of a gamble. You should check what current your PC draws and the amperage rating of the PSU. If the PSU can handle it, you might be fine!
My PC needs 6.32A, and the PSU gives 11.79A. Does that help?
