Overview

The Logitech 8541645500 is the official replacement USB nano-receiver for the G900 Chaos Spectrum gaming mouse — a single-purpose component that restores the wireless operating mode of one of Logitech's most technically accomplished wireless mice. The G900's wireless architecture achieves 1000Hz polling rate over its proprietary 2.4GHz protocol, maintaining the sub-1ms effective input lag that competitive gaming demands. The receiver is factory-paired to function with any G900 Chaos Spectrum mouse without additional configuration: install it in a USB port, and the mouse reconnects to its full wireless specification. This is a genuine Logitech OEM part — not a third-party receiver claiming compatibility — which matters because the G900's proprietary protocol requires hardware-level firmware matching that generic wireless receivers cannot provide.

This receiver exists for one scenario: a G900 Chaos Spectrum user whose original nano-receiver has been lost. The G900 operates in both wired and wireless modes, so a missing receiver only eliminates wireless operation — the mouse remains usable via its USB cable until the receiver is replaced. For competitive players who use the G900 specifically for its wireless-at-wired-latency performance, restoring wireless operation with this replacement is worth the purchase. The component-level nature of this product means there is no meaningful compatibility decision to make — if you own a G900 Chaos Spectrum and need a replacement receiver, this is the correct and only validated solution.

Frequently Asked Questions

Will this replacement receiver automatically pair with my G900 mouse, or does it require a pairing process?

Logitech's USB nano receivers for the G900 use a pre-paired configuration from the factory — in most cases, the replacement receiver will pair directly with the G900 without any software steps. If automatic pairing does not occur, Logitech Connection Utility software can force a pairing sequence between the receiver and the mouse.

Will this USB receiver work with any other Logitech wireless mouse, or is it locked to the G900 Chaos Spectrum?

This receiver is specifically designed and validated for the G900 Chaos Spectrum only. It is not a Unifying receiver and will not pair with other Logitech wireless mice. If you're looking for a multi-device receiver, the Logitech Unifying receiver is a separate product that covers the Unifying-compatible mouse lineup.

What wireless protocol does the G900 receiver use, and what does that mean for latency?

The G900 uses Logitech's proprietary 2.4GHz wireless protocol — the same protocol underlying the Lightspeed standard — rather than Bluetooth. This dedicated protocol maintains sub-1ms effective wireless latency in competitive gaming conditions, which is operationally indistinguishable from wired input. Bluetooth mice at the same polling rate exhibit higher latency under RF congestion.

Does this replacement receiver support Logitech Unifying, or is it dedicated to the G900 only?

This receiver is dedicated to the G900 Chaos Spectrum and is not a Unifying receiver. It cannot connect to other Logitech devices using the Unifying protocol. Only the G900 is compatible with this specific receiver unit.

Will using this replacement receiver affect the G900's wireless latency or report rate?

No. The wireless performance characteristics — including the G900's 1ms wireless report rate and LIGHTSPEED-class signal processing — are determined by the mouse's onboard hardware and firmware. The replacement receiver operates to the same electrical specification as the original, so latency and report rate are unaffected.

My G900 receiver was lost — will my existing mouse work correctly with this replacement?

Yes. The G900 receiver requires no additional pairing procedure — it is factory-matched to function with any G900 Chaos Spectrum mouse out of the box. Connect it to a USB port and the mouse will reconnect to its 1ms report rate wireless operation immediately.

Does the receiver support the G900's full 1ms (1000Hz) polling rate in wireless mode?

Yes. The G900's 2.4GHz receiver maintains the full 1000Hz polling rate in wireless mode — the same report rate as a wired connection. This is the technical differentiator of the G900 platform: wireless operation without the polling rate compromise that older wireless gaming mice imposed.

What USB port type does this receiver require?

The receiver uses a standard USB-A nano connector — it plugs into any full-size USB Type-A port. It does not require USB 3.0; USB 2.0 provides sufficient bandwidth for the receiver's wireless data rate. For USB-C-only machines, a USB-A to USB-C adapter is required.

Is this receiver covered by Logitech's warranty, and is it a genuine Logitech part?

This is listed as a genuine Logitech replacement part. As an accessory component, warranty coverage terms depend on the seller — buyers should confirm warranty terms at point of purchase if coverage is a concern.

Should I plug this receiver directly into my PC or use a USB extension cable?

For optimal signal performance, plug the receiver into a USB port as close to the mouse operating area as possible. If your PC tower is on the floor or behind the desk, a short USB 2.0 extension cable (30-50cm) positioned at desktop level will improve signal consistency by reducing the air distance between receiver and mouse.

Strengths & Trade-offs

👍 Pros

Genuine Logitech part restores the G900's designed wireless signal specification — including the mouse's native report rate — without the compatibility uncertainty of third-party receiver alternatives
Factory-matched to the G900 Chaos Spectrum — connects immediately without pairing software or additional configuration, restoring wireless operation in under 30 seconds
Maintains the G900's full 1000Hz polling rate in wireless mode, preserving the sub-1ms effective input latency that defines the G900's competitive gaming performance specification
Nano USB-A form factor sits flush in the USB port with minimal protrusion, avoiding the physical leverage stress that full-size USB dongles exert on port housings during transport
Dedicated single-device pairing eliminates any risk of cross-device wireless interference from shared Unifying receiver traffic
Dedicated 2.4GHz proprietary protocol avoids the interference and latency variability that Bluetooth connections introduce in RF-congested environments
Genuine OEM replacement from Logitech ensures firmware and protocol compatibility that third-party USB receivers cannot guarantee for this specific mouse
No driver installation required — the receiver enumerates as an HID device and the G900's existing Logitech G HUB software profile continues to function without reconfiguration
Restores the full wireless functionality of the G900 (including wired/wireless mode switching) at a fraction of the cost of replacing the entire mouse
Small USB nano-dongle form factor occupies a single USB port without blocking adjacent USB ports on compact motherboard rear I/O panels

👎 Cons

Compatible exclusively with the G900 Chaos Spectrum — provides no additional value if the user later upgrades to a different Logitech mouse model that uses a different receiver standard
Single-device compatibility — this receiver pairs only with the G900 Chaos Spectrum and cannot be re-paired to any other Logitech mouse model, making it a zero-versatility purchase
No Unifying receiver support means G900 users cannot consolidate this receiver with other Logitech wireless peripherals under the Unifying protocol to free up USB ports
Nano receiver physical size makes it easy to misplace again — a secondary USB port or included tether/storage solution is not provided
USB-A only form factor requires an adapter on USB-C-only machines, adding a dongle-on-dongle scenario that undermines the flush, minimal profile of the nano receiver design
If this replacement receiver is also lost, there is no software pairing option — the G900 becomes permanently wireless-inoperable unless another receiver is sourced
Receiver operates only in the 2.4GHz band, which shares spectrum with Wi-Fi and other ISM band devices — in extremely congested RF environments, signal reliability may degrade
No onboard indicator for pairing status — if the receiver fails to auto-pair with the G900, diagnosing the issue requires downloading Logitech Connection Utility separately
Single-unit purchase with no backup — losing or damaging this replacement creates the same procurement problem as the original loss
No physical power indicator or connection status LED provides no visual feedback that the receiver is active and communicating with the mouse
