Guys I think he's only selling the box, and not the actual power supply.
I do not understand your reasoning behind writing this. You sent me a message on ebay and asked me. I told you the listing is for the actual 600W power supply.
It's a common scammer tactic on ebay to list the box, then the buyer gets angry when they get just the box when they were expecting what was INSIDE the box. I see you canceled the auction and relisted it to indicate you arent selling just the box anymore. You should maybe edit your OP to indicate you aren't selling a box anymore. (you might be implying you are selling the actual power supply, but so long as it says you are selling the power supply BOX, I think you are just selling the box and not the power supply)
btw, don't think many people will bite on this, regardless. when it comes to power supply, brand means everything. it could be labeled as a 1000 watt power supply, but if it has shit parts in it because its a no-name brand, you'd be lucky if it powered 150 watts without blowing up and burning up your more valuable PC equipment like CPU, RAM, video card, hard drive, etc.
