FREQUENTLY ASKED QUESTIONS
Is this a direct replacement for my Acer Aspire AM3400? 
Yes, the power supply is guaranteed to fit your Acer Aspire AM3400 perfectly. 

Is this the correct shape and size? 
Yes, this will be the same shape, size, and dimensions.

Does this have the correct cable connectors?
Yes, you will have all the the needed connectors for all the devices.

This replacement unit says it is 450 watts, that is higher than what is currently in my computer, are you sure this will work?
Yes, the higher wattage is actually better. The 450 watts is a maximum output. This will work perfectly as an upgrade over your lower wattage power supply. Think of it as extra power if it is needed for extra devices. Otherwise it just uses the amount it needs. Furthermore, since the power supply is a higher wattage, it is much more reliable.

The voltage and wattage 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?
This is designed to work perfect as a replacement for your unit. This is also an upgrade as it is a higher wattage which can handle more devices: hard drives, DVD drives, Ram or CPU if you choose to add them. 
This power supply also adds higher efficiency. Further, this power supply is newly manufactured with newer components internally. Also it offers: over voltage protection, over power protection, short circuit protection, low noise and ripple fan, Energy star efficient. This is why this exceeds getting an exact/original replacement that was most likely manufactured years ago with older parts/technology. Also, capacitors go bad over time, even when not is use. Plus this comes with a one year manufacture warranty.
