So i just bought an r9 280 off amazon with a 550W power supply, because i wanted to have the same fps as my friend, but now it heats up so much i could cook on it, i think its a the power supply because my friend got 600w and as i said i have 550w maybe its because of that also its not a popular brand so maybe it really is the psu please someone help me solve this problem.hes my specs: IbUYPOWER Desktop PC ARC Series NE621FX AMD FX-Series FX-6300 (3.50 GHz) 8 GB DDR3 1 TB HDD Windows 10 Home 64-Bit.http://www.newegg.ca/Product/Product.aspx?Item=N82E16817170010&_ga=1.202741777.1076926558.1452089213
