Doesn't look like a Pico-Box or Genuine Pico-PSU. Your results may vary wildly - I've had an unbranded 80w unit cope with 160w, but I've heard horror stories of others losing boards to no-name products.
Plus, I wouldn't want to push 160w thru the barrel connector - they tend to melt. Woops >.>
I second that about the melting. Had one go on me a couple weeks ago at the end of a gaming session. I hate to think what could have happened if I hadn't been right at the computer when it went : /
