you're better off buying a new 450W PSU maybe a CX450 or CV450, they'll do with a 1650.Hi i am looking to see if anyone knows of a 300 watt psu for the acer aspire xc-886 because i want to buy a gtx 1650 lp 4gb and could i also use the card only with 220 watts and under power it with the msi afterburner

What is your CPU?
I think using a 75W GPU on a system with only a 220W PSU might be trouble.
The closest I came was with a Dell, which was a 220W PSU (18A available on the 12V rail, so 216W of the power available on the 12V rail), and the GPU I used was only 55W max, but the CPU was also only about 54W max.
It would be helpful if you could get a clear image of the power supply label, so we'll know who makes it, and how much power is made available on the 12V rail(s). Some OEM power supplies are notorious for not providing enough on the 12V rail.
Still need to know what CPU you have.
BUT, at 15A on the 12V rail, that's a total of 180W. I'd be EXTREMELY hesitant to go with adding in a 75W card, unless you have a low-power CPU.
You'd be much safer with, say, a GT 1030 - maybe the 1650 is viable if you have a 55W or less CPU. If you have a CPU with a higher draw, though, I think you'd be cutting it a bit close.
thats ok but still thank youI don't know - I imagine the drop in performance might make it not be worthwhile, but I have no experience in doing that. I don't know how much power you'd save in undervolting it, nor how much the performance would be reduced.
