Lenovo ThinkStation P3 Tiny Gen 2 Power Configurator

Overview

The ThinkStation P3 Tiny Gen 2 is the latest desktop workstation in the ThinkStation family, succeeding the P3 Tiny. Unlike traditional desktops, the P3 Tiny Gen 2 does not feature an internal power supply. Instead, it utilizes an external power adapter, similar to those used with ThinkPad or ThinkStation Ultra SFF computers. Three external power adapter options are available for the P3 Ultra, with power ratings of 170W, 230W, and 330W. This document aims to provide detailed specifications of system components with the highest power demands, enabling informed decisions when selecting the appropriate PSU for your hardware configuration.

Section 1 – Key Architectural Design

The P3 Tiny Gen 2 is powered by an external power adapter connected to the rear of the system. The three available power adapters are rated for 100-240V AC input and provide a 20V DC output. The power cord connector is a 20V type, also found on some ThinkPad computers. Figure 1 illustrates the rear view of the P3 Tiny Gen 2, highlighting its connectors:

The P3 Tiny Gen 2 is equipped with a single PCIe x16 slot designed to accommodate select low-profile GPUs and other PCIe cards. This is achieved through a PCIe x16 riser card for supported GPUs or a PCIe x4 riser card for other PCIe devices. Figure 2 shows the motherboard's PCIe slot on the P3 Tiny Gen 2, with no PCIe device installed.

Section 2 – Power Ratings for Key System Components

To fully understand the power capabilities of the ThinkStation P3 Tiny Gen 2, it is essential to know the power ratings of its individual system components. The following tables detail the power ratings for the various CPUs supported by the P3 Tiny Gen 2. All supported CPUs include integrated graphics.

Table 1 - Arrow Lake CPUs Power Rating

Currently, the P3 Tiny Gen 2 supports either the A400 or A1000 for a discrete GPU.

Section 3 – P3 Tiny Gen 2 Power Configurations

As previously stated, the P3 Tiny Gen 2 supports 170W, 230W, and 330W power adapters. Table 2 outlines the minimum required power supply for various CPU and GPU combinations.

NOTES

• *Can ship with either 170W or 230W PSU from Lenovo.

P3 Tiny Gen 2 Power Configuration Notes:

• All supported GPUs require the use of the PCIe x16 riser. Other supported PCIe cards necessitate the PCIe x4 riser. Refer to the Appendix for more details.
• The premium internal speaker cannot be utilized if the system is configured with an A400 or A1000 installed.

Section 4 – Board-To-Board (BTB) Cards

The P3 Tiny Gen 2 offers expanded system rear I/O capabilities through the use of Board-To-Board (BTB) cards. Two BTB connectors on the motherboard facilitate extensive customization based on user requirements. This section covers the currently available BTB cards. It is important to note that when any BTB cards are installed, no PCIe device can be placed in the PCIe x16 slot. Consult the Appendix for images and part numbers of all supported BTB cards.

P3 Tiny Gen 2 BTB Configuration Notes:

• The Dual & Quad USB BTB cards occupy the entire width of the rear I/O, preventing the simultaneous installation of other BTB cards.
• The P3 Tiny Gen 2 can support up to two of the following BTB cards: DP, HDMI2.0 (4K), HDMI2.1 (8K), VGA, 2.5G LAN.
• Single-width BTB cards can be mixed.
• The P3 Tiny Gen 2 supports up to one USB-C BTB card, which must be installed in the BTB1 port.
• The P3 Tiny Gen 2 supports up to one Thunderbolt 4 BTB card, which must be installed in the BTB2 port.

Appendix

This section provides supplementary information regarding the hardware used in P3 Tiny Gen 2 systems. Table 3 lists the available BTB cards for the P3 Tiny Gen 2 as of the document's creation.

PCIe Risers

PCIe risers are installed at the factory based on system configuration. If no PCIe device is selected during the initial purchase, no riser will be installed in the system. The part numbers for the risers are provided below. An M3x6 screw is recommended for securing the riser to the side of the chassis.

• PCIe x16 Riser - 5C50W32107
• PCIe x4 Riser - 5C50W00909
