Installed a GTX 1660 TI in my XPS 8500 i7 3770. It will require a newer power supply with a 6 pin connector to power the video card. Stock PS only has 4 Pin. But once installed, it works perfectly! Very good card and system upgrade for this PC. Getting HIGH FPS!
what PSU, watts?
what card exactly makers (10+) and 25 sub models made, even fan counts and DDR ram sizes small to huge.
the card needs 120watts all by itself.
does the card run FURMARK and not crash,
make sure the card has lots of cool are or they can overheat, cooling matters.
run gpu-z to see how hot it gets, full tilt.? that be like first thing once, booted.
