Poly 875M7AA Power Supply for Poly Studio X50, X70 and Studio USB
Original Poly partStudio X50 / X70 / USBAC 120 / 230 VCord not included
The Poly 875M7AA is the original external power supply for the Poly Studio X50, Poly Studio X70 and Poly Studio USB video bars, supplied without the mains power cord. It is the part to order when a meeting room video bar has lost its power supply, when you move a bar to another room, or when you want a spare on hand for critical rooms.
HP Poly sells it as a separate accessory for these three video bars. Because it comes without the country-specific AC cord, you either reuse the cord already in the room or order the correct one for Cyprus (UK-type BS 1363 plug) with it.
Before you order: HP lists this supply for Poly Studio X50, Studio X70 and Studio USB only. Other Poly devices, such as Studio E70 cameras or desk phones, use different power supplies. Send us the model on the device label if you are not sure.
What's in the Box
- 1 × Poly power supply 875M7AA
- No AC power cord (order the correct country cord separately if needed)
What It Means in Practice
- If a video bar will not power on after a move or a power surge, swapping in an original supply is the quickest way to rule out the adapter.
- Keeping one spare supply for several rooms with the same video bar models avoids a meeting room being out of service while waiting for a part.
- You can reuse the existing AC cord from the old supply, as long as it is undamaged.
What Will Not Work
- It does not include the AC power cord.
- It is not listed for Poly Studio E70, Poly Studio R30, desk phones or headsets.
- It does not power a Studio X50 or X70 over PoE or USB; it is the mains supply only.
- HP does not publish the output rating on the official spec sheet, so do not use it for non-Poly devices.

Frequently Asked Questions
Which power cord do I need in Cyprus?
A cord with a UK-type BS 1363 plug that matches the supply inlet. Tell us and we will add the right cord to your order.
Will it work with the Poly Studio E70?
No. The E70 uses a different supply. This part is listed for Studio X50, Studio X70 and Studio USB.
How do I know my bar needs a new supply?
If the bar shows no power LED with a known-good socket and cord, the supply is the most likely cause. Send us the model and symptoms and we will help confirm.
Singular Expert Insight · Buyer's Guide
Power supplies for meeting room hardware are small parts that stop a whole room when they fail. Matching the exact Poly part avoids guesswork with generic adapters of the same voltage. If the room also needs a PoE switch for its touch controller or cameras, see our
network switches.
✓ Buy it if you have a Poly Studio X50, X70 or Studio USB that needs a replacement or spare supply.
✕ Skip it if your Poly device is another model, or you also need a power cord and cannot reuse the old one (order both together).
→ Also consider a UK-type power cord for Cyprus, and spare supplies for every room with the same video bar.
