By "not for gaming" that's exactly what I mean. It's a workstation card. For productivity and design work. It's not meant for gaming. It's not a gaming card. Cancel it.
Trying to use a Quadro card for gaming is like trying to use a Prius for doing construction. Yeah, it will get you there, but you'll be seriously limited in what you can do on the job and it's going to really suck if you need to carry a load. Same thing here.
You want a gaming card, and, you REALLY want to replace that PSU. It's a serious piece of worthlessness when it comes to being used with any kind of gaming card. Sorry Matt, but there's no way I'd recommend trying to run a 1650 Super that needs a six pin connector on a PSU that when new could barely do 350w, but is now somewhere between 10 and 12 years old because that unit hasn't been manufactured since about 2010 so far as I know. Any of them out there for sale from the last few years are certainly old stock unless Thermalfake is running production on 2008 platforms.
With the price of things right now, considering the major push for gaming purchases by people stuck at home for the last few months, and the lack of any re-supply from China where 99% of these power supplies and graphics cards are manufactured, there's no realistic way you can get a worthwhile graphics card AND a halfway decent power supply for 200 dollars, in the Canadian market. Used, maybe, but that's an incredible risk in my opinion. Not worth the risk to be honest. About the best I can see right now, even for a very basic entry level graphics card that is at least moderately capable at 1080p and a decent, but budget power supply that isn't a complete turd, you're looking at about 300 bucks CA.
Used you might have a lot more options, but you also have exceedingly more risk involved and if you, or anybody else, actually believes that Ebay will enforce a refund if you get a graphics card that takes a crap after a week or a month, then you, and they, are just fooling yourselves. If it's used, and the person you are buying it from isn't somebody you know well enough to invite to your mother's house for dinner, then it's a poor option IMO.
