X51 R1 Power Supply upgrade from 240w to 330W Question.

#1
Want to install an EVGA GeForce GTX 1060 SC GAMING, 06G-P4-6163-KR, 6GB GDDR5, ACX 2.0 (Single Fan) to push my 4K monitor. I'm about 5w short on power with my configuration to meet the 120w card requirement.
The question is if I purchase the 330w power supply brick is that all I need, to upgrade my power supply 90w.

Thanks,

Jeff
