Is this your computer: HP Desktop - M01-F0033w Product Specifications | HP® Customer Support

If so, why are you thinking about an upgrade to the power-supply?

yes that is precisely it.

Well basically I'm trying to make this an office and gaming computer and I have to get the psu upgraded in order to safely put in a graphics card and also possibly upgrade the cpu. I am looking to put in a low profile gpu more specifically a gtx 1660 low profile. It says that it tales 120 watts so the standard 180 is probably not sufficient.

For a "gaming" computer, you should use a high-performance SSD, because it consumes less wattage than a lower-performance "spinning" disk-drive.

What other devices are in your computer, that might consume many of the remaining 60 watts (out of the 180) ? Motherboard? CD/DVD? Fans? Power to the USB ports?
