The minimum PSU I'd use for those specs is an 850w. However, I would recommend getting a 1000w so you have the power headroom and future upgradeability.

The power supply won’t blow up but it may shut down on overcurrent. 
 

5950 TDP 105W

6950 XT TDP 335W

 

Add some for the motherboard, peripherals, external USB devices and the load will match or exceed 650W.  Peak power for CPU and GPU will be significantly more. Transient load spikes and overclocking will cross the line.

If you undervolt the GPU and CPU you could potentially skate by for a very short amount of time. If you notice any crashing or have any restarts or shutdowns unprompted I'd recommend not running the system on the 650w anymore.

And again I'd like to reiterate, it should be fine temporarily running it on the 650w with the parts undervolted and underclocked. You need to get an 850w or higher as soon as you possibly can if you don't want to risk your components and want to run the parts as intended.

Honestly, if money is that tight, just hold off until you can afford it.  An 850w PSU is only $125 or so.  If that breaks you....
