CPU: Intel Pentium G4560
MOBO: ASUS H110M-D
RAM: GSKill AEGIS 4GB DDR4 2133mhz
Case: AVF Casing with 450W PSU
SSD: WD 1TB Caviar Blue HDD

Currently I want to make this build w/o gpu and use for watch movie on my 40' FHD TV

Later I will pair up with gtx 1060 3gb

May I know is there any issue on usage with the PSU 450W?
And any issue with gaming while using TV?
