Pros: Needed 2 6 pin pcie for HiS R9 270x. 400w PSU only came with 1. Was skeptical to try this as the 270x "requires" a 500w psu and I didn't want to fry anything. Has worked perfectly (so far) for 3 days of intense gameplay. Inspected cords to see if there are any issues and it looks good as new.

Cons: None so far.

Overall Review: I should mention I haven't overclocked the 270x and don't intend to with this PSU / connector out of paranoia, but this product does work as described.
