Power Supply Replacement (M81)

I have a ThinkCentre M81 which has been regularly shutting down without warning and then re-booting.

A technician saw that the power supply does not appear to be the correct type and suggested that I replace it.

The M81 manual indicates that the model is equipped with a 280w power supply.  The Lenovo website lists a 240w power supply as the replacement model for the M81.

Will using the 240w power supply cause the same problems?

Why doesn't Lenovo offer the 280w power supply that it indicates comes with the machine originally.

Thanks.

Re: Power Supply Replacement (M81)

Is a tower model or small form factor (SFF)?

A 240w watt power supply is sufficient for a SFF system.   See this thread:  M83-SFF-PSU-and-Graphics-upgrade

Re: Power Supply Replacement (M81)

Hi everybody,

 

Can you explain a little more about this thread?

 

I have a ThinkCentre M81 (7518-D2S, SFF) and I would like to add a MSI GEFORCE GT 710 1GD3H LP.

 

Recommended PSU for that graphics card is 300W so I would like to upgrade 240W factory LiteOn PSU.

 

Is it possible?

 

Thank you in advance!

Re: Power Supply Replacement (M81)

ThinkCentre systems with PCIe slots, including SFF, have power supplies sized to accommodate a low-power (35w) graphics card. 

 

That said, I remember that there's a quirk to the Nvidia adapters supported, skipping over the GT 710.  Some people on the forum tried it, and it failed to boot.  I just checked the latest Nvidia driver readme file on the M81 support page, and the GT 710 is still missing.
