THE CHOSEN ONE
yeah sure ill post the DAMAGE
fine thanx............if smps is not trusted what is maximum damage it can give to my pc
Let me explain a bit. The confusion has been created due to the re-branding of cards by AMD. For example HD 6770 and HD 6750 are just rebranded HD 5770 and HD 5750 respectively with 3D support through BIOS update.
after adding a discrete GPU, due to the overload, it may give deliver wrong voltages that can damage almost everything thats attached to it including the motherboard, CPU, GPU, Hard Drives, Optical Drives, and other stuffs.
@ OP
You asked what maximum harm it can cause to other PC components. I didn't say your existing PSU will damage your PC if you add a HD 6670. That card doesn't even require an additional PCIe Power Source.
