Hey there. I'm looking to upgrade my graphic card from a GTX 1050 to a GTX 1660 (both not Ti). However, i'll need a new PSU, or else it'll be underpowered, knowing that my current 1050 already is a bit over my current PSU's peak wattage(350W).

Here's my specs (Tell me if you need more details) :

OS: Windows 10 64x
CPU: Intel Core i5 3330 3GHz ivy bridge
Motherboard: ASUSTeK COMPUTER INC. CM6330_CM6630_CM6730_CM6830_M11AA (LGA1155) (mATX) (yes, this entire thing is the model name)

I'm looking for a 400-450W PSU, since that's about the total wattage of my system.

I've done a bit of research, and i've had my eyes on this product : https://www.amazon.com/Seasonic-S12II-520-SS-520GB-Capacitor/dp/B07MWHYQRC/ref=sr_1_1?keywords=seasonic+s12ii+520w+80++bronze+certified+atx+power+supply&qid=1565559144&s=gateway&sr=8-1&th=1

I THINK it could work out, but not being as much of a PC connoisseur as i'd like to be means i can't be 100% sure.

Would it be compatible with my current hardware? If not, why is isn't it?

? All PSUs are not the same. The seasonic listed isn't bad, but it's a much older design. Pick one of these.

650W gold and modular psu for $50. Much better idea.
I see. However, the 650W is pretty overkill, and i'd rather do as much savings as possible. It also jumps from $80 to $100 in CAD, which is somewhat inconvenient as i'm on a tight budget. Is the S12III really not that worth it?

It's a bronze psu instead of gold. It's based on an ancient design, and it lacks nearly all forms of protection. Here is where we talk about it for a bit.

It's not going to blow up on you. But there are much better psus out there.
Well i guess i'll just listen to you and get the Corsair RM550x you suggested. However, seeing as the GTX 1660 requires an 8-pin connector, do i need an additional adapter? Or is the 8-pin already included? Also, seeing as this is an ATX power supply, will it be compatible with an mATX motherboard(I'm guessing it is, but i'd just like to be sure)?

This is plenty for your configuration considering that RM unit is not that price in your region, but is about forty dollars more. If you can afford the 550w version of either the CX (2017 version) or RM, then obviously those are better choices, but if not, you should not have problems with the unit below as even the TI version of the 1660 only calls for a 450w unit.
