yep get a new and better PSU, for example a decent brand like BeQuiet. Will be much more expensive than that 15 pounds PSU you showed us, but still cheaper than buying multiple trashy ones and especially buying a new motherboard when your PSU bites the dust (happened to me).
500w-550w should be enough. Expect to spend around 50 pounds.
