Will PSU fit my case

[Exonado]

This is my computer specs: http://www.cnet.com/products/acer-aspire-m3300-e1222-athlon-ii-x4-620-2-6-ghz-4-gb-750-gb/specs/
I was planning to buy this PSU: http://www.amazon.ca/gp/product/B005CP07PQ/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=A3DWYIK6Y9EEQB&tag=gdext-ca-20
My old PSU is an Acer Liteon PS-6301-08A 300W

I assume my computer is MicroATX so I believe that this PSU will fit my computer but I am not 100% sure. Would this PSU be good and fit my computer or is there any other PSU's that I should consider getting

you can get a 500W-550W psu to fit in there

seasonic/antec hcg/corsair cx 430m or cx 500m etc...

here are a couple of solid psu's at 550w http://ca.pcpartpicker.com/parts/compare/antec-power-supply-bp550plus%2Cxfx-power-supply-p1550sxxb9/

this is a good power range that will allow for a better gpu when you get around to upgrading it. if you are not going to upgrade it, then here are some less powerful ones to go with http://ca.pcpartpicker.com/parts/compare/corsair-power-supply-cx430%2Cevga-power-supply-100w10430kr/

these are lower quality psu's but would be good enough in the current system if it is never upgraded.

For a prebuilt , here is a good OEM sized PSU that will fit in the case.
