when buying a tower, how would i know if the psu fits in that tower

[itami]

i know there are different sizes of psu and i look at this one tower and i fail to see or there is no info on what psu will fit into that tower

ATX power supplies will fit into ATX towers. ATX.

in some m-atx cases some atx psu's fit and some dont. its best to find the case you want and make sure the motherboard, cpu cooler and psu will fit in that order or find the cpu cooler and mother board you want and find a case that fits those components. it depends on your setup. i know i have given you too much information but just trying to save the back and forth. its best to give as much info as you can. and most times a quick google will answer 90% of the questions you might have but np

i had it easy one time, i had 2 towers about the same size(i suppose same form factor), almost the same or same not sure, one of them had bad psu so i switch psu but it did not fit in the tower, still i plug in the psu to motherboard and it worked, so i ordered the psu based on the computer model

now how do i make sure it fits in the mid tower based on what? you said form factor is not the answer

cases will usually have a size for a psu in mm that will fit in it. and psu's will have sizes similar so you should be able to find something.

if you are talking about a dell or a proprietary psu that came in a pre-built computer then it might take some searching but you will be able to find something.

what pc's are they and what psus do you have/ are looking at?

just looking at mid tower in tigerdirect and newegg, to see if i can just buy the tower and the rest of the components later cause my old computer broke so might as well update to a new one

ya totally you can just buy the components one at a time
