So I have many graphical errors on my pc when I play games where my gpu can run them at High settings but I have to run them at Low settings or they crash or if I put the graphics high I get texture loss and my games crash. So I think it's because of my psu I believe its some kind of chinese because it doesnt say who manufactured it, its not corsair, evga, cooler master, or any other it just says the wattage the voltage etc. So how can I find out how much wattage psu I need for my pc I am planning on buying an evga or cooler master (bought the pc pre-build). And there is no issue with my gpu.

ok, so getting a more reputable brand that uses reliable components is a must for PSU, however, I don't know how many watts you will need for your system and neither will anybody else here on the forums since you haven't told us what hardware your PC has that the PSU will need to power. In general though, I'd say a 650w will power pretty much anything, unless you are running dual GPU's overclocked and are overclocking your CPU pretty hard as well.

CPU wattage+GPU wattage+150W for the motherboard+20%= your PSU wattage
my rig
125W+250W+150W= 525W, I opted for a 600 as my math estimate is high on the motherboard front just to be safe.
when you have the wattage needed add 20% and you have the ideal, IMHO, wattage PSU to get.

you cannot judge a PSU by brand, EVGA and Corsair make some real stinkers. cooler master, no just no.
what are your specs?

you can also go to Pcpartpicker.com and enter the parts in your pc there it will give you an estimated wattage

That m12ii is poor value when the CX450/450M is selling for $15 while being a much better power supply.

If a power supply was needed, aim for a quality 400w+ PSU. Examples include the Corsair CX450m, be Quiet Pure Power 10 400.

Your issues don't point towards the power supply. Usually when a PSU faults, it will cause a full system crash/reboots.
