5V max limit by ATX Spec for SSD's

JKR82 — Tue, 08 Aug 2023 05:54:23 GMT

Hi,

I am currently having a discussion about how many volts a 2.5'' SSD must be able to withstand. Regarding the Intel "developer_specs_ATX12V_1_3dg" chapter 3.2.1 the allowed max voltage for +5VDC is max +5.25V. However in chapter 3.4.1 Over-voltage Protection it says, "The supply shall provide latchmode over-voltage protection as defined in Table 14", and that is max 7.0V for the +5VDC rail.
How does Intel see this, do 2.5'' SSD's have to withstand 7.0V DC without interference to be used on ATX board?
Or are there 2.5'' Intel SSD's that are specified up to 7.0V, so that they can operate without hesitation on ATX power supplies?

Hello, JKR82.

This post is to inform you about the closure of this community thread.

I previously wanted to get more information regarding the drive (or drives) being used to check if there were any recommendations we could share, but there was no response from your part after trying to follow up.

The thread will be closed right now, and it will no longer be monitored by Intel support, but if you require any type of assistance from Intel in the future, just open a new thread, or contact us using any of the available support methods:
