Hi,
I have an HP Z400 with a 475 80 Plus Bronze PSU.
I m wondering if I can use a GTX 760 wich is supposed to have a 500W PSU.
The GTX 760 has a TDP of 170W. My CPU has a TDP of 95W. I have an SSD,HDD and DVD drive.
It looks like it should be fine. I m currenlty using a 150W TDP GPU without any issue. I wondering if those extra 20W will cause any system instability.
The detailled tech specs of my PSU are
