Re: Upgrade a 300watt noname power supply

... I don't know which rectifier is what so i don't know which is the the 3,3, 5 and 12v rectifier. Can you tell me which rectifier is what? ...

The color of the output wires can give you a clue:

Often the +3.3V rectifier is aligned with the orange wires, the +5V with the reds, the +12V with the yellows.

To be sure test for continuity between the center leg of each rectifer and the orange/red/yellow wires.

On your PSU, the BYQ28E is for the 12V, the STPS2045CT is for the 5V rail, and the STPS1545CT is for the 3.3V.

EDIT, you could use those other heat sinks, but maybe bend the fins outwards, that way, you will get some airflow between them

The OEM for this PSU is Channel Well (CWT).

How can you tell that this is Channel Well and not Solytec/L&C?

The part numbers on the transformers don't looks like L&C, neither do the heat sinks, and L&C have never used Fuhjyyu caps (whereas CWT love them).

The PSU in post #20 is an L&C, though

EDIT: Maybe I should add that the OP's PSU looks like it is from their ISO division, and so it lacks some of the usual CWT features, like green tape and CWT markings on the transformers.
