Best power supply and wattage for Hyper Neogeo64

[Arcade-Projects]

Hello All,l recently acquired a HGN 64 fighting board ,l am uncertain of the wattage needed for the power supply. l have a 133 watt power supply in my cps 1, 2,3 and neogeo 1 slot which work with no issues. Also l have a 150watt supply in my neogeo mv4. I think with the l/O board in the HNG64 will draw more power than the 133w can provide.
My questions are,

What wattage is the best for the HNG64?

Will a 150watt supply be good enough for the HNG64?

Thanks for your attention
