According to the specs in the link you posted, the Cooler Master is significantly larger than your current PSU (several inches in each dimension). Your best bet would be to look inside your case and see how much room there is around the power supply, and check to see that you have the clearance to install the larger one. It also would be a good idea to measure the one you have installed, just to make sure that the specs on that page are accurate. If they are, that is a very small power supply.

Ok well do you happen to know any PSU's that could possibly fit into my computer? And the dimensions of the PSU that is already in the computer are Length: 3.84 inches Width: 2.85 inches Height: 1.54 inches

alright well then i have this question i was also planning on upgrading my graphics card too (because im trying to make it into a better gaming computer), but if i want a pretty good graphics card then the card will need more watt's. I've been looking for a good graphics card but all of them usually need around a minimum of 450 watt power supply requirement. But the problem is then that my PSU doesn't give out enough wattage. The psu that i have only gives out 300w.
