need psu help

Cesarito32

So i'm trying to restore an old pc for my mom and do some upgrades but the power supply doesn't fit in the case, so i want to buy a new one but i don't want to ruin the parts or anything, the power supply that doesn't fit is a 485 watt, would a 600 watt be too much or can i do 600? if 600 is too much could i use a 500 watt?

Hello @Cesarito32 and thanks for posting on the Microcenter Community Forum. As far as size to obtain a PSU that will fit, you'll want to look at the PC's form factor.

What is the make and model of the PC you are upgrading?

We can look up the PCs form factor (ex., SFF, etc.).

As far as watts, you could go with a 500 or 600 watt PSU; the PC will only use the necessary wattage it needs to power up the components. So if you put in a 1000 watt PSU and the PC only needs 400 watts to run, it will only draw 400 watts from the 1000w PSU.

Hey @Cesarito32 !

Using a wattage over what you currently have won't be an issue at all! The components from inside the machine will take just what it needs. It will not cause damage to the machine.
