Those all sound like BSoDs you get when your RAM isn't quite 100%. Run a memory test (MemTest86 is the one I use) to ensure your RAM is stable. If you have DOCP on, turn it off and try your games again.

I have the exact same Gigabyte RX570 4g model that you are contemplating. In my opinion, as an RX570 user, I would go for the 1650 super. It has a lower TDP with a higher base and boost clock, as well as 4gb of GDDR6 instead of GDDR5 like the RX570.

the gtx 1650 super is much better in thermals, and powers. it also is like rx 580, so iwould get gtx 1650 super.

Hi Jon. I thought it could be trusted because Xigmatek looks like a rather big a popular brand here. I see a lot of its product and bought that PSU from one of the biggest PC component distributors in Vietnam.
After your comment I did also dropped by the store again and became officially lost in the world of PSU and electricity...
Yes that PSU is Vietnam only https://www.xigmatek.com/product_detail.php?item=220 Ouch that 80 Plus sign is fake? I never seen any other model... No each of the column in the PSU's wattage table does NOT represent one power cable? One tech guy brought me a 24 pin cable and started telling hey red means 12V yellow means -12V (something like that). I mean... wow... And the saddest part is NO everyone here and there say I should not add RX 570 to this PSU, even if I don't overclock at all. The website even says this VGA needs 150W https://www.amd.com/en/products/graphics/radeon-rx-570 I'm totally baffled. Then how should I calculate how big my PSU should be if the basic math CPU 65W VGA 150W is less than 400W does not work?
 
 

Thank you all so much for the quick help. My PSU can be trusted. It is a Xigmatek X-POWER II 450 with 400W real power (as I see in the table on the box). It is also of 80 Plus standard.
 
My confusion originated from a rather popular formula from youtube guides:
Recommended PSU = CPU TDP + VGA TDP + 200W I assume 200W was just a safe advice? In my case my CPU (65W) and VGA definitely won't exceed 300W. The remaining 100W could well be spent on 2-3 SSDs and fans right?
