thats good news! its not a great one but enough to run a R9 280x. it has a 12v rail of 38A and 2x6+2pin pcie power cables.!however i wouldnt overclock cpu or gpu with it for any reason! since its a semi modular psu you should have the pcie power cable needed laying in some box!
prebuilt systems rarely come with quality psu.! however you can open your side panel and check the psu sticker for make and specs. you need a 12v rail of 30A and 1x6+2pin pcie & 1x6pin pcie power cables to run such gpu.!
