Psu requirement for Vega 56 OC

[ghalvz]

Hello, I am new to overclocking and was wondering if a 750W corsair cxm would be enough to support a slight overclock in a vega 56 (say to 1520 or 1550 mhz); my current pc specs
I7-7700k/hyper 212 evo heatsink
Tuf z270 mark 2 motherboard
Rx 480
16 gig ddr4
Razer Gaming mouse/keyboard
1 monitor (thinking about getting a 2nd)
An xbox 1 controller
3 120 mm case fans (I believe - rosewill challenger case)

Any feedback would be helpful, I've looked up requirements on psu calculators, but I've had a card fry with insufficient power a few years ago so I'm a bit scared to get within 100 watts even if that may be a bit irrational.

550w , 750 is pure overkill.

The vega cards in general can be power hungry especially when overclocked. I have seen from reviews that systems with a Vega 56 overclocked can hit over 450w system draw. Factor in as well a cpu overclock and that will increase a bit again. None the less though your PSU (if you already have it) is more than enough to handle your system.
