Is Running 7950 with a 500W cooler master thunder safe?

post #1 of 3
Thread Starter 
Okay ,so its my first post here,I am gonna buy a new graphic card soon and i can afford a 7950 and a 660 TI ( i know both are similiar in performance ) but the main problem is my PSU which is Cooler master thunder 500W ( Its not a quality unit but cant really change it for a year ) , I know it can handle a 660 TI but i want to know can it handle 7950? some say it can same say it cant.


Will it be safe to run a 7950 ? with this PSU?

Details of my PSU -

It has 2x+12v rails

+12v1-24A
+12v2-21A



My Rig-

Fx8120

gigabyte 970a

8gb ram

i am not into overclocking


details of the PSU if needed

The 7950 specs state that it requires a 500w PSU with a minimum of 25a on a single rail. That PSU doesn't have quite enough amperage on either of the 12v rails. It would probably run it, but I wouldn't recommend it. It would be putting enormous strain on the PSU and would be underpowering the GPU, which could lead to problems down the road. It could also shut down under a very heavy load. I hope this is helpful.
