I'm currently planning to upgrade my graphics card in my PC. However a few years back I bought a Recom Power Engine 550w plus PSU. This PSU only has 1 6pin PCI power cable. The XFX HD7950 I want to buy needs ofcourse 2 x 6pin PCI power cables.
I've read online that it is possible to buy a sata to PCI Power adapter. However I've also read that the Sata to PCI power adapter needs to output the correct amperes.
I'm not really into electricity stuff so could you guys please help me out? Should I buy that adapter for only a few dollars or should I upgrade (again) to a newer/better PSU?
