How can I know the ATX 12V Specification number for a PSU?

[sbab123]

Hi guys,

I am currently building a PC from scratch for the first time and I am facing some difficulties. I am sure people here can help me and you have already done until now.

I was reading through the manual of my motherboard, when I read:

We recommend that you use a power supply unit (PSU) that complies with ATX 12 V Specification 2.0 (or later version).

What the hell is ATX 12 V Specification 2.0?

I am planning on buying the SEASONIC S12II 620W PSU and I had a look online, and nothing says that it complies with ATX 12 V Specification 2.0, or later version...

How can I know whether this PSU I will buy complies with the ATX 12 V Specification 2.0, or later version?

Regards

You have no need to worry about the ATX specification; it's been basically the same for a long time with minor changes, and anything you buy today will be based off the latest spec. However, most all units still fail some parts of the ATX spec unfortunately.
