I am looking at purchasing this pc: http://h20564.www2.hp.com/hpsc/doc/public/display?docId=c04554329 I don't have much experience with graphics cards but I know I'd want a better one than the Geforce gt 705. In the above link it tells me I only have 180w, that seems low to me and also amazon tells me I have 500w which seems a little high. https://www.amazon.co.uk/gp/aw/d/B00SBB9M7C/ref=mp_s_a_1_1?ie=UTF8&qid=1489955415&sr=1-1&m=A3P5ROKL5A1OLE&pi=AC_SX236_SY340_FMwebp_QL65&dpPl=1&dpID=3105OFgAG4L&ref=plSrch#featureBulletsAndDetailBullets_secondary_view_div_1489955432760 I don't know which figure is correct. I'm looking at the gtx 750ti. Would this be compatible with that pc? It says that I need 300w psu for the gtx.
 
Solution
You may be able to buy a power supply for that system to run a better card, it should be able to fit a standard ATX PSU in the case and the motherboard connectors are standard ATX ones.
I would believe the 180W number, and the HP site says it's an external hard drive. This is not a computer meant for upgrades. You could get a low profile 750 Ti but it uses about 40W more power than the stock 705. That's a significant difference when your power supply is only 180W and I bet it's not really outputting 180W either.
