Question regarding power supplies

[TomsRT]

Im looking at a replacement PS for my ATX case, do all PS's have the same dimensions?

All ATX spec power supplies have the save height and width which facilitates mounting in any ATX case, but larger wattage PSU's are typically longer (front to back of case) than smaller wattage PSU's. Just look for a PSU labeled as "ATX".

no. look for PSU that are ATX spec or ATX/EPS (most are)

what case do you have?

Matrix, don't know the model #.
