Can I Use a 19.5V Power Supply for My 19V PC?
Asked by
CuriousFox123
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.

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!

.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!

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!

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.

No way, it’s definitely not safe. Stick with what’s recommended, no exceptions.

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!
