I have a ASRock P55 Pro motherboard and i was wondering if it would support a Asus Nvidia GeForce GTX 750 Ti Graphics Card.

Yes it will, the GPU has PCIe 3.0 x16, the motherboard has PCIe 2.0 x16 but they will just cause into a MINOR performance loss. But it will work

They're just different brands. They generally offer better cooling and higher clocks than the reference 950 card. The most common ones are MSI, Gigabyte, Asus, EVGA and Zotac. They're all pretty solid, so look around for the card you like the best.

I don't think your PSU has any PCIe power connectors. It is possible to use a 4 pin peripheral cable (aka molex) to 6 pin PCIe adapter, and some of the less powerful cards come with them. http://www.playtool.com/pages/psuconnectors/connectors.html#pciexpress
The next issues is your PSU isn't a high quality unit and at only 300W you risk damaging your system if you put a too powerful card in. You may get away with a GTX 750 or the 750Ti, but unless you can afford a new PSU, don't put anything more powerful than that in. And don't think I'm being unfair, if you had of posted this question in the "Graphics card" section, you would have a dozen people tell you not to even risk a GTX 750 as your PSU could burn your house down.....I think some of them over-react, but they know the importance of a good PSU.

Wow, that's good to know. So do you think I should get a new PSU before upgrading my Graphics Card? I currently have 2 ATI Radeon HD 5450 1gb as I got my computer 5 years ago and they're not enough for games such as BF3 and CS. Do you have any suggestions of graphics cards that would support these games and be compatible with my PSU/Motherboard?

definitely upgrade your PSU to a 650W will make it easier for you in the long run if you plan to do any other PC upgrade/changes in the next 10-20 years just make sure you get a reliable brand such as antec, corsair, XFX, seasonic

with 300W your system will short out when you run games with a new graphics card that is if it will even run.

Usually if you look up the graphics card it will tell you the minimum wattage it requires, in the case of 750ti it would be 300w but note that your system needs power to drive the motherboard, ram, cpu and other components not just your GPU.

There's also the efficiency of a power supply which is rated in grades of plat to bronze (you can read up on that if you want) Nevertheless upgrade your PSU if you are tight with funds you can get by with a 550W PSU which retails at around 70$US can find them on sale for 50$US (assuming you reside in the US).

Your cheapest option is to get a GTX 750Ti, but don't go overclocking it as you will already be at the limit of what's safe with your PSU. BTW, the Asus versions of the card usually requires a PCIe power connector, maybe look at the EVGA (but not the FTW), MSI, or even a cheap Zotak is alright. All of the cards will be PCIe 3.0 but work just fine in a 2.0 slot.
If you haven't already figured out how much better a 750Ti is compared to a HD 5450 http://www.hwcompare.com/17373/geforce-gtx-750-ti-vs-radeon-hd-5450/

Now if you have a lot of money (or you can get it from your dad), get a good quality PSU of at least 400W, don't go below tier 3 http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html
Then get either a GTX 950 or a 960, these cards are a huge improvement again.

Just been think about this, and realized something, you have a 5 year old computer. Depending on what CPU it has, you probably can't even run a GPU any more powerful than a 750Ti anyway. Spending more on a better GPU would be a waste of money unless you intend to upgrade everything in the not too distant future.

The 300W is recommended for the whole system, but in reality power consumption is going to be lower.

This is a real world test comparing a 750Ti against over GPUs using an i7, remember this is whole system usage http://www.techspot.com/review/783-geforce-gtx-750-ti-vs-radeon-r7-265/page11.html

I will point out that even though it gets nowhere close to 300W, you never want to push a PSU to it's max, especially if it's a cheaper unit.

Well the thing here is that he's using a generic brand PSU ISO-400PP 300W which in reality is not providing 300W at all. I make my recommendations cause I use to run a gtx 550ti dell with a liteon 400W PSU quite some time back and it shutted down when running games for a certain amount of time cause depending on the game or program (editing programs, photoshop, DAWs or what not) running the computer will draw out more energy and sometimes may have minor spikes and thus result in auto restarts so yes in normal situations it won't ever pass 300W but define your real world/normal use, would it also include running a game off of steam?
