XPG PSUs are actually really good to my surprise.
I was really hesitant on recommending them at first.
Then going through the internet and a whole bunch of reviews and experienced opinions, They are quite reliable.
Almost as reliable as Corsairs Gold PSUs.
But make sure to get the Gold PSUs from XPG, as the bronze ones aren't up to the par and you can definitely grab better corsair ones at that price point.
XPG Core Reactor 650W Gold should be your choice.

The only other alternative around your budget is the Coolermaster MWE Gold V2 750W at 22.5K but that's over your budget.
Only these 2 I recommend currently.
If you can find a Corsair TX650M or TX550M Gold PSU (Grey/Black Label) Then grab those. Same prices around the XPG Core Reactor as well.
Avoid Gigabyte and 1stPlayer PSUs at all cost.
