Service manual for MS-7826 Kalili motherboard, upgrade PSU in Envy Phoenix 810

[Rasumusu]

This is a long shot, I know.

I want to buy a new PSU for my computer, but I know that pre-built systems often use proprietary motherboards. Therefore I would want a service manual for my motherboard MS-7826 to see if the pinning in the power connections are the standard ATX one or not.

Anyone have a service manual or have changed their PSU in a Envy Phoenix 810-201no

Greetings,

Welcome back to the forum.

I am not a HP employee.

I have never worked on the 810-201no or the installed MSI (Kaili) motherboard. Unfortunately, HP does not provide PSU pinout information.

I have upgraded PSUs on 810 series HP PCs having the Pittsburgh motherboard and the Pittsburgh2 Motherboard. Both Pittsburgh motherboard 24 pin power connectors were standard ATX connections.

The PSU upgrades went very well.

The length of the new PSU (other PSU dimensions wil be similar) should be as close as possible to the existing PSU. A very long PSU will butt up against the optical drive power and data connectors.

HP does provide very general PSU replacement instructions at this site (Link) starting on page 36.

Some of the latest gen consumer HP PCs don't use a 24 pin PSU connector on the motherboard.

The connectors are labeled ATX_Power etc. Would that be a guarantee for it being standard? Or is there still a risk for an alternative pin layout?

I really don't wanna fry the motherboard...

Hi.

I can't answer this question.

The alternative pin layout risk does exist.

I don't want to see you fry your motherboard either. 

Maybe a different forum member has first hand experience with your specific PC.
