I have a friend who wants to start PC gaming. He has a Gateway dx4870-ub21p desktop computer and wants to add a graphics card. He is thinking about the R9 270x. Will his 300W PSU be able to handle it? Will there be enough room in his case? The R9 270x's Max TDP is 180W. If it won't work out, what can we do to get the graphics card in there? Thanks.

I would advise to get a new power supply before considering getting a gpu. A 500W should be sufficient for a R9 270X.
A GTX 750 Ti is a safer option but ideally a better power supply is recommended first.

OK. If he gets this PSU, will he be good to go? will it fit in his case and everything? http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Corsair CX series aren't great power supplies, their quality is mediocre.
EVGA 500B isn't the best but it is a step above CX series.

OK legit. same price too! So will the card fit in his case? He bought the PC pre-assembled so I dont know how much room is in there and it would be a real bummer to get the card then not have enough space.

Measure the clearance from the rear to the front. Stop where there is obstacles. Measure at where the graphic would be plugged in. Once you know the clearance, look up the specs of the R9 270X you buying at the length of the card. Compare results. Different brands of R9 270X have different lengths
