I know the reason for the six pin connector is if you want to OC the card but I thought the whole point of these GTX 1650s was for people who just want to stick one into their DELL, ACER, HP, etc., and not worry about swapping out a higher power PSU.
Most 1650 will not have a 6-pin.
This MSI (much like other reviewed card from ASUS) are top models for this GPU - with factory OC and some headroom for you. Their predecessors (both 1050 and 1050Ti) also had a 6-pin despite 75W TDP.
Really? If you're that worried about the power consumption I hope you're using expensive TV's and Fridges that are energy efficient too.
It's not about peak power usage of the household (although I know people who worry about it as well because of solar power or tariffs).
It's about pure cost of a card.
At some point (hours of GPU usage) the cost of extra power used will consume the initial price difference. It's not that hard to calculate as well.
Keep in mind power prices really vary around the globe. In many developed countries it's 50-100% more expensive than in US.
And if the final cost is the same, GTX gets you less noise and heat.
Extra 100W can really impact room temperature and it gets noticeable in summer.
My point being it doesn't make a significant impact on your bill, and there's something called undervolting which works best on vega but it's worth a shot on the RX 570 even which will drop power consumption a bit and it still kills the 1650 in performance.
1650 is a mainstream consumer card. You can't expect these people to undervolt.
And if we're talking about OEM/SI desktops, you may not be allowed to.
