To check if it's it's split rail PSU. A single rail PSU and I move ahead. A quad rail 550W and it's replaced with a single rail. Dual rail? Gets iffy, would have to check specs.
I have a NVIDIA GeForce GTX 750 Ti and Intel(R) Core(TM) i5-4460 CPU @ 3.20GHz PSU 550 W. I want to change my gtx 750 ti to an msi geforce 1060!
If i do this,i need to change PSU or cpu or something else?
