Manufacturer Response:

Thank you for submitting your review of our product. We at ACPC strive to manufacture and offer quality products. This user seems to have been experiencing issues based upon his/her configuration. However, in response to his/her statement concerning that our product will "fry your motherboard", it is apparent that he/she has very little understanding of how modern PSUs are built. There are many standard internal protections offered on ACPC PSU products, as well as, those of our competitors such as Over Voltage Protection, Over Current Protection, etc. In regards to our RMA policy, our policy is to hold a deposit amount for the value of the replacement PSU. The freight of the replacement PSU to the user is billed to ACPC. If the user returns the RMA PSU in their possession, to our facility, we will release the deposit amount immediately.

Should users experience issues with the product, or have questions, we do highly encourage he/she to contact our Customer Service at 626-510-5008 or via email at
