I am looking to upgrade my graphics performance in this build. Only planning to upgrade the graphics and no other components as I want to keep this build under a certain budget. The only concern I have is with with the power requirements that most high end GPUs require.
To lower power consumption, (Thought I'm not sure if that makes any difference at all) I'm using:
- AMD CPU with a max TDP of 95W,
- Low power GREEN SATA HDD.
- Only one 120mm regular case exhaust fan
If I'm not mistaken, my power supply is of decent quality and is quite reliable. It's rated @ 430W with 28A (336W) on the 12V rail, and has only one 6+2 pin PCI-E power connector.
So far, I'm really leaning towards an XFX AMD RADEON 6850. I read about many people running these on Antec EarthWatts 380W/450W PSUs so I'm wondering if I would be okay with a Corsair 430W? I read that these only require 25A on the 12V rail and a single PCI-E connector.
This graphics card seems to be the best bang for buck, as well as the limit (TDP of 127W) for the CX430V2 PSU that I currently have.
Note: I do not plan to buy a new PSU for this rig... because I just bought it over the summer... and that would really be a waste of money T~T
My concern with this card is that it requires TWO (2) PCI-E power connectors, when my PSU has only one. I have plenty of the molex-to-PCI-E adapters which I could use; and I have PLENTY of free molex headers....
Does anyone think that this is a viable solution? Will this work in the long run?
I've read a lot about the 6850s requiring only 1 PCI-E power connector to begin with, but I can't seem to find any of those models at a decent price...
