Hi there
I'm currently running a 6850 and a 5850 on a 600W Corsair PSU in:
Corsair 600W CX Builder Series 80 Plus PSU
Core i7 2600k
Corsair Vengeance 8GB (2x4GB) DDR3 1600Mhz
Gigabyte GA-Z68X-UD3-B3 Z68 Socket 1155
Arctic Cooling Freezer 7 Pro rev 2 Socket 1155
1 SSD
1 HD (7200)
3 120 MM fans
1 140 MM Fan
1 DVD RW
Will i be ok to replace my 5850 with a 7950 and keep using the same PSU or am i going to have issues?
Also what happens if you draw too much power from your PSU does it shut down or blow?
Working backwards forwards. Usually to much power will cause things to screw up. You will see shit like your ram not functioning. Fans slowing down. Hardware heating up, Strange Sounds from the PSU. Over time the PSU if built properly will just die without hurting any hardware. Poorly built PSUs will explode. But mostly the caps swell and shit burns up on the psus pcb.
I decided to build a rig for catching up on a few years of gameing and some alt coin mineing. I have some of the samw le specs as you minus the dvd rom..
As said in the post above you CAN do it. But myself I like to allow for a buffer. As said a breakdown of hardware will help
