Hello, I have a new ACER ATC 705 pc, and I am switching out the PSU to install my psu (Inland 650w) from the other computer and to install my GPU. ( r9 270X)

I noticed that when I took the psu out of the acer pc, it showed a 3.3v of 20 and a 5v of 26.
It also showed a -12v of 0.8A

My inlandpsu is 3.3v 15A and 5v 15A
and -12v 0.3a.

Does this mean I need to get a new psu? the inland psu was powering an older costume built pc
that was still using lga775. But this newer pc is different and I'm not sure if I can use this psu, or if its even enough

Its not on the radar as being good. i don't even see it being bronze rated.


plug in your computer parts and it will give you the wattage estimation. add 20% then get that wattage+....
