I only go for PSUs that are at least 70USD or more... So... What's your definition of cheap?
Inexpensive-cheap. It can be quality-cheap as long as there won't be a chance of it exploding my computer when it decides to die. It would also be nice if the wattage its labeled as is the actual wattage it contains. I suppose I'm fine with 500W, but I wanted to leave room in case I upgrade my PC in the near future to a stronger gaming rig. I don't really want to replace parts if I don't have to.
