Ugh I truly don't know how to search for this particular psu is there any key I could use to find it? All I found was a manual nothing else don't know if it's of mScreenshot_20201212_090606_com.android.chrome.jpguch help

They tend not to release their schematics so I'm pretty sure you won't find one on the internet.

If somebody has one perhaps they can take a look?

From the picture, I see only 2 legs and an insulating strip behind it. That suggests a diode of some sort, or perhaps even a thermal switch/fuse. If a thermal switch, is may have gone open like a fuse, stopping the circuit. Try to find the part number. Remove it and do a diode test with a multimeter to see if it is a diode or is "open" or "shorted"

It should be stamped on the component. Can you take a closeup of just the component? Also of the area of the PCB where the component is placed.

It is clearly marked on the PCB D23 which is a diode and the component markings indicate BY-C15 which is a Hyppefast power diode. extension://nhppiemcomgngbgdeffdgkhnkjlgpcdi/data/pdf.js/web/viewer.html?file=http%3A%2F%2Fpdf.datasheetcatalog.com%2Fdatasheet%2FNXP_Semiconductors%2FBYC15-600.pdf

The PCB markings in the other spots are for transistors. Without them or a schematic specifying them you are outta luck.

OK first of all thanks for your answers, now OK, if you look to the sides of that hyppefast diode you mention theres a silhouette of the transistors that were there clearly bigger than than that, I remember the components had 3 legs.

Please can anyone help me determine what type and model of transistor this psu uses(voltage, amp, etc), the one it had were removed and I have no idea what Trans use D:
They have a TO247 case & could be FETs, type SPW20N60C3 20.7A 650V Check if the device driving them is a transformer, in which case they could be transistors, of in IC design to drive FETs. the datasheet of the device will tell you.
