You get a PSU that fits your needs.

The AMD FX 6300 is a 95W TDP processor The processor, motherboard and a single 4gb stick of ram goes over your power budget (I calculated based off this site - and it suggests you'd use 152w at load - but looking at the TDP alone tells me something is off).

In theory you could power the fans off the motherboard (but once again, you're cutting it REALLY thin on how much power you have), and a cheap PSU is more likely to do strange things that close to their capasity.

That said, its somewhat unlikely its a 150w PSU. From memory, even the cheapest PSUs you commonly come across are 350W or more. Its also unlikely someone would throw an enthusiast grade processor and a very nice case and somehow throw in a grossly underpowered PSU.

If you're on a budget, there's seriously cheap powersupplys of over 250w around. If you're not, get a good powersupply with some headroom.

This is without taking into account storage, and a video card, which the FX family would need
