Question Looking for a decent, inexpensive PSU to put in older XPS PC?

Will be for my young son to play games on it (nothing extreme, no overclocking etc.) Upgrading the GPU to a GTX1650. The current PSU works (350w) it's about 8yrs old, only ever used to get online or stream videos; do you think the current PSU will be ok with the new GPU put in? If not what would be the lowest cost, reliable PSU I could put in there; just 450w or so?
 
If it's a GDDR5 GTX 1650 (not "Rev. 2.0 or "Super" or "KO"), then it likely doesn't have nor need a PCI-E 6-pin power cable. (If it does, one can be adapted from a spare SATA power lead, if you have any available).

Regardless, a PSU upgrade will solve all of those problems, anyway.

If you were going to upgrade to an RTX 3070 or higher, I would stick in a 600W (80Plus Gold preferred, but make sure it's at least 80Plus, White is the lowest these days) from a name-brand.

If you just want the GTX 1650 for now, and don't want to worry about GPU upgrades until the time comes, than any decent 450W would do.

A Corsair CX450 is a popular choice, although they aren't as cheap as they used to be 4-5 years ago, they used to be $40 with a $20 rebate quite often. Now they're around $50-55 before any rebates.

Edit: If your current PSU is 8 years old, then I do recommend replacing it, if you are going to drive a GPU (even a slot-powered one). It may work on the existing PSU, but for how long? Afte 8 years, unless it has a 10-year-plus warranty with JPN caps., then it's best to replace PSUs after 5-6 years, unless they are "put out to pasture" on an iGPU system, as yours used to be.

You're right about the Corsair CX450, so am wondering if there are 450w PSUs for less $$ that'd be comparable to the CX450?
 
There's the Gigabyte and Montech PSUs @ Newegg that I kind of wonder about. If they are decent, they could be a good alternative at low wattages, and Montech offers some in 80Plus Gold at an affordable price, but I don't know enough about them to actually give them a thumbs-up or thumbs-down.

EVGA 80Plus White 500W is another alternative, sometimes you can catch those for $40 on sale @ Newegg.
 
EVGA presently has a few B-stock power supplies in the $40-$55 range on their website.

Well, I was going to post a link, but got this:

Maybe they managed to post an RTX-3080 for sale and the bots went berserk??? 😉

Are the EVGA White & Bronze 500w as good as Corsair CX450?
