I want to add a 7870 graphics card but as as in most off the shelf PCs the PSU sucks and cant support the card. To add cherry to the icing, the connectors on the PSUs are not standard 24/20 pin. They are 12 pin connectors which means that I'm not going to get a normal aftermarket power supply. If someone has a tried and tested method of upgrading the power supply, purchasing an additional power supply just for graphics card please share. Thanks in advance!

On the reviews on amazon people who said they did try to upgrade their power supply had failed because of the 12pin connectors. I think the best possible upgrade for that system would be a 750 ti which doesn't require any power connectors but it gives you even more power than most of the 6 pin video cards that I have seen.

That's pretty much your only option other than switching the motherboard.
