Acceptable PSU Voltage Drop ?

stock12to32
Level 10
I have recently purchased a Lepa 1600W Full Modular PSU. I am getting some big drops in voltages even under small loads and I am wondering what is acceptable.
I have messaged Lepa a few days ago and still waiting on a return message from them.
I had a Antec 900W High Current Gamer PSU in my system and I would monitor my voltages and they would stay above the spec voltage.12v 5v 3.3v
I have a lot of stuff running in my computer with it being water cooled and I did not want to burn the Antec up so I purchased a Lepa 1600w PSU and when I put a load on the system through games I notice I big voltage drop. 12v = 11.74v, 5v = 4.8v and 3.3v = 2.8v.

Is that ok or should I be looking for a RMA on the PSU ?

I am judging this by how my Antec PSU performed, but the Lepa is gold certified.
I am getting the readings from AIsuite but it seemed to have done a good job on monitoring my Antec.
I have read the support page on the Lepa website and I have plugged PSU directly in to the wall. I made sure that I have spit the power load on each 12v rail and it did not make any difference.

I suggest to use a multimeter to test all the RAIL for the actual reading of your PSU.
Change is the law of life. And those who look only to the past or present are certain to miss the future.

I think you may have missed my last post. I no longer have this problem. I did test with a multimeter and got good results. Also found out why AISuite was reading low and it is fixed. Thank you though 😛
