get a new PSU, the R7 370 needs a 450w unit (recommended) and that Lepa is not putting out what its says its rated at.

This right now is a steal https://pcpartpicker.com/product/sMM323/evga-supernova-g3-550w-80-gold-certified-fully-modular-atx-power-supply-220-g3-0550

i found the problem before pc shuts off gpu is at 105c and at idle is 50c in like 1 second it gains 55c i think the thermal chip on card is broken any ideas?

before i had R7 260x and i did overclock crap out of it and psu wasnt limiting it R7 370 use even less power than 260x

Both recommend a 450w PSU and the R7 370 only uses 5 watts less in power.

starting at a 50*c I would pull the card apart and makes sure it has good thermal paste and tape between the card and the cooler.

yea thermal paste is from low end and gpu now is working only 100 to 104c so yea im getting liquid metal
