Lenovo P3 Ultra ThinkStation P3 Ultra Platform Desktop

Overview

The ThinkStation P3 Ultra platform is the new desktop workstation that replaces the P360 Ultra in the Lenovo ThinkStation family. As a successor of ThinkStation P360 Ultra, the P3 Ultra does not have an internal power supply. Instead, it is powered by an external power adapter, similar to that from a ThinkPad or ThinkStation Tiny computer. There are three different power adapters available for P3 Ultra, each with a different power rating (Watts): 170W, 230W, and 300W. The goal of this document is to highlight the specs of the system components with the highest power demand and allow you to make the best decisions when choosing the correct PSU for your hardware configuration.

Section 1 – Key Architectural Design

As mentioned above, the P3 Ultra is powered by an external power adapter that is connected to the rear of the system. Each of the three available power adapters are rated at 100-240V AC input with 20V DC output. The power cord connector is a standard 20V connector, available on many mobile WorkStation notebook computers. The P3 Ultra rear 20V connector is shown in Figure 1:

Another design feature of the P3 Ultra is that it has PCIe connectors on both the top and bottom of the system motherboard. As shown in the Figure 2 below, the top of the board contains a Mobile PCI Express Module (MXM) x16 slot and the bottom have a PCIe x8 slot (limited to x4 electrically).

The MXM slot on the CPU side of the board, in some configurations, requires using a x16 riser card (FRU# 5C51D95675) that positions the PCIe card parallel to the motherboard.

Here is a view of the rear of the system with the Nvidia T1000 installed (with a riser card):

Please refer to the P3 Ultra Hardware Maintenance Manual for detailed PCIe card installation instructions.

Section 2 – Power Ratings for Key System Components

To fully understand the power capabilities of the ThinkStation P3 Ultra, it is important to know the power ratings of the individual system components. Table 1 below shows the power ratings for the various CPUs supported on P3 Ultra.
Note : All CPUs supported on P3 Ultra have integrated graphics.

Table 2 – Raptor Lake CPUs Power Rating

Table 3 – Raptor Lake Refresh CPUs Power Rating

Table 4 below lists the power ratings for the various PCIe add-in cards supported on P3 Ultra.

Notes:

• PCIe cards are length-limited due to the compact chassis design.
• Stated Max Power Rating of GPUs may vary from specifications given by vendors or other online sources

Section 3 – P3 Ultra Power Configurations
As mentioned previously, P3 Ultra supports 170W, 230W, and 300W power adapters, which allow customers to tailor their system to best meet the requirements of the components they intend to support. The following diagrams and notes show allowable hardware configurations for systems with either power supply.
Note : See Table 4 for supported single-wide and double-wide GPUs referenced in the diagrams below.

Note : See Table 4 for supported single-wide and double-wide GPUs referenced in the diagrams above.

P3 Ultra Power Supply Configuration Notes:

• Officially supported configurations could still be limited by additional factors not defined within this document.
• PCIe cards are length-limited due to the compact chassis design.
• For configurations that are not listed above but appear to be feasible, please work with the Technical Solutions Team to have the configuration validated/vetted.
