Overview
PowerRiser v2.2 is an open-source printed circuit board by nandfarm, from the nandfarm/PowerRiser repository on GitHub, published under the CERN-OHL-S-2.0 licence. It is a 4-layer board of 119.1 × 23 mm with 22 parts on 101 nets, routed with 1,201 tracks and 214 vias.
It is built around the AS0BC21-S30BM-7H. Its parts include 5 resistors, 3 capacitors, 1 IC, 1 diode and 1 connector. It belongs with the computers and single-board computers and interfaces and adapters boards of this library.

PowerRiser Board
PowerRiser is a custom-designed passive riser board that allows you to break out the proprietary Lenovo Tiny 5 series PCIe connector into a standard open-ended x8 PCIe slot, while also providing an additional M.2 NVMe slot (2230/2242 sizes only) for further storage expansion. This board was specifically designed for select Lenovo Tiny 5 series systems (8th/9th gen), such as:
-
ThinkCentre M720q
-
ThinkCentre M920q
-
ThinkCentre M920x
-
ThinkStation P330 Tiny
These boards are compatible with the following Levono riser FRU codes: 01AJ940, 01AJ902, 01AJ929. Basically if you are looking for any of the risers with the FRU codes mentioned above, this riser will do the same job and will allow you access to an extra 4 lane NVMe M.2 2230 or 2242 slot.
⚠ Please note: The additional M.2 slot supports only PCIe NVMe drives, not SATA drives.
Background
This project is inspired by the TinyRiser board originally designed by WifiCable. After building a batch of TinyRisers for personal use and realizing some of my Lenovo Tiny systems had clearance issues (due to the WiFi/BT expansion boards), I decided to create my own variant — which I now call PowerRiser. If you are considering using 2260 or 2280 (with caution) NVMEs, please connect with WifiCable for details on how to acquire the TinyRiser.
PowerRiser was developed to:
-
Avoid clearance conflicts with other expansion boards.
-
Allow installation of short NVMe drives (2230/2242) without obstruction.
-
Provide an open-ended x8 PCIe connector that can accept longer x16 PCIe cards (electrically still x8).
Physically, the only modification required is removing the front metal bracket that holds the Bluetooth antenna. (Please refer to the photos in the repo for installation examples, including with an x16 graphics card installed.)
Usage & Limitations
You can safely install longer PCIe cards (x16), but electrically the slot remains x8.
NVMe drives supported: 2230 and 2242 sizes only.
This riser is only compatible with the Lenovo Tiny 5 series models listed above.
SATA M.2 drives are not supported on the added M.2 slot.
The riser is cabable of accepting x16 PCIe boards but in order for them to be detected, the "PCIe_Detect" solder bridge on the back needs to be bridged.

Project Origin & Intent
This project was built from personal need, trial, and experimentation and so far I have built about 20 boards for my own setups and for others. I hope it helps others facing the same limitations with their Lenovo Tiny builds.

Reports from buyers
As some amy know I have sent a mass email to everyone who bought this board to ask what drive they are using and if they had issues with them. So many replies! Thank you all for the support. Below is the list with everything I received. I will update it as things come in. Keep in mind that this is not an exhaustive list. There are many moderls of drives out there and all should be compatible. If you do find anything let me know!

-
SK Hynix 2230 BC711 512GB -> works but ASPM needs to be turned off in bios, or disable the L1.1 and L1.2 substates in the OS.
-
Micron 2400 Series MTFDKCD1T0QFM 1TB -> gets detected at Windows startup but then dissapears. Probably also a ASPM related issue but no further tests were made.
