Hi all,

Been reading & googling all around Internet for an upgrade for my GTX 960. Finally decided on ASUS GTX 1660 Super (see link below)

So I bought this new GPU yesterday along with 6pin-8pin adapter. Hooked it up but PC was not able to detect the new 1660 Graphics Card.
Checked on Device manager & there wasn't 1660 showing up :(

- I have had my BIOS flashed to the latest : 1.2.15
- External Power Brick of 330W
- Used single 6-pin to 8-pin adapter to connect to GC. Must i use a dual 6-pin to 8-pin instead?

Any advise on this?
