Question Is 650W enough for my build?

[BlueSilver]

Hi, i just wanna try if you're kind enough to give a piece of advice. I currently have this pc setup and about to buy a graphics card for it.
CPU: AMD Ryzen 5 3400G unlocked
RAM: G.Skill Trident Z RGB 16GB (8GBx2) 3200MHz
MB: MSI B450M Mortar Max
SSD: Seagate BarraCuda Compute 500GB 2.5"
HDD: Seagate BarraCuda 1 TB 3.5" 7200RPM
PSU: Thermaltake Litepower 650W

Some days ago, I'm looking for the best graphics card for my budget and after watching some reviews, it all pointed at GTX 1660 Super. Now my problem is my power supply. Will my setup still work after mounting this graphics card? If it would still work but really need to change power supply, it should be okay to use this power supply temporarily right?

Please help me ease my mind, jk. Please give some advice. Thank you

The wattage is enough, but that series of psus is not the best.

That system will actually be able to run on 450 watts (i usually take 100 watts more than what it could run on without a problem) so take a 550w (if you want to replace it)

you dont have to replace your psu, but it would be better since that isnt a high quality one.

Think you'll be fine for now, as said will the pc be under a not that high of a load so the psu won't be that highly stressed. Just don't wait until warranty is over to replace the psu.

Thank you. I'll remember this and will replace this psu of mine when there's a need for upgrade again. Thanks

The power you need is mainly gated by the graphics card.
Here is a handy chart:

I have no problem overprovisioning a PSU a bit. Say 20%.
It will allow for a stronger future graphics card upgrade.
It will run cooler, quieter, and more efficiently in the middle third of it's range.
A PSU will only use the wattage demanded of it, regardless of it's max capability.

Of more importance is the quality of the unit.
A cheap unit will advertise power at room temperature, not at 50c which you might see in a case.
Look for at least a tier 3 unit on a list such as this:

The psu you listed is tier 6.
