baha.ayadi :
I have an old Asrock H61M-HVGS (2011 release) and i want to upgrade my gpu to Gtx 1050 , my mbd supports pci express 2.0 x16 and should work with new gpus but the latest bios version is 2012...
can you help me guys ?
Yes, it will work fine.
GPU's are PCIE cards. They are backward compatible. So most modern GPU's will be PCIE 3.0, and they fit and work fine in a PCIE 2.0 slot.
The 1050 does not need any extra power cables, and will power itself from the slot.
Just make sure you have a good enough PSU to run it. A decent 450w PSU is fine for that.
