R9 280x with 650w PSU?, its heating alot

[faresse11]

hi, so my uncle gave me a new computer for my birthday and its a pretty good midrang pc, here are the specs:
CPU: i5-4430 @3.00GHz
GPU: Saphhire Dual-x R9 280x
RAM: 8GB @ 1600MHz
HDD: 2 5200rpm
PSU: CoolerMaster GXII 650w
and the case gets really hot, i dont know what brand it is but it has a "Pc." logo on the front.also the pwoersupply gets really hot, but i used a pwer calculator and it said that i needs 526w on load. is there anything i can do to prevent that heating, im afraid that somthig will fry.

does the case have intake and exhaust fans?

Pics of the case , internal & external would help.

To me personally it sounds simply like a case airflow problem.

Are there any case fans fitted, if so what configuration.?

That PC won't pull more than 400w fully stressed , the psu is more than enough wattage wise

does the case have intake and exhaust fans?

You have mounting for intake fan at the front and an exhaust at the back.

I would recommend getting a couple of 120mm fans so you have intake and exhaust and some good airflow.
