Hello, I believe that this unit is what I need to replace the old supply in my desktop, however the values listed for output current are significantly higher than on the original. I am assuming that this is not a problem as these values are only what it is capable of delivering, but I just wanted to make sure that this unit is definitely compatible despite the differing values. Please let me know. Yes, This will work perfectly as a replacement and upgrade for your HP Pavilion 7855 , this is designed to work perfect as a replacement for your unit.
