I have some very specific questions about a PSU and MB
Last response: in Motherboards
Hey guys,
I am currently in a situation where my MB lacks documentation on its ports. The exact motherboard I am referring to is this one:
H-RS880-uATX
My first question is how do I know if I am plugging my SATA III-compatible HDD into a SATA II port on this motherboard? I have been looking around for documentation on which is SATA I and SATA II and to no avail.
Does anyone know?
Also:
I'm in another situation where I had disconnected my PSU via pulling the power plug when it was in operation before the OS starts. Will this have any immediate or future damage to the Power Supply if I pulled the plug during POST 3 times while it was on?
I heard a spark noise each time I pulled it (I don't know what I was thinking) but it still works out ok. I was just wondering if that could damage the PSU if I did that during POST?

Best solution
The AMD 785G chipset on the motherboard determines the SATA revision supported. That chipset supports 6 SATA 2.0 devices.
Since SATA 2.0 ports are backward compatible with SATA 1.0 devices that is why HP listed both Sata 1.0 and Sata 2.0 on the Internal Connectors list but nowhere does it mention the number of each type because that is irrelevant when all six SATA ports are SATA 2.0.
Pulling the AC power cable during POST is equivalent to a power grid failure occurring during POST.

I want my PSU to last for at least 3 years because I just bought it...
The sparking sound may have been coming from the outlet/plug. When you pull the plug it can cause a spark in the gap created between the plug and socket. Try not to do this in the future. If you do not know what you were thinking perhaps you were not thinking at all. Mindless actions often lead to disappointment with their outcomes.
