A:AnswerThe general recommendation for a GTX 1660 super card is a 450 watt power supply, so if the card is shutting off regularly, it's probably that the 400 watt power supply doesn't have enough headroom to properly drive the video card.
A:AnswerThank you for the question. Memory, processor, and storage are sufficient, but you'd probably want to add a dedicated graphics card, since the integrated Intel UHD Graphics 630 may not excel at 3D graphics.
