#### **Cons:**

1. **Cost** Genuine Onkyo replacement parts are often more expensive than aftermarket alternatives. Depending on availability, prices may range from **$150 $300 **, depending on the seller and condition.

2. **Limited Availability** Onkyo has phased out many older models, making this part harder to find than generic power supply modules. You may need to order from specialty audio repair shops or eBay.

3. **Potential Counterfeit Risks** If purchasing from an untrusted seller (e.g., random online marketplaces), there s a risk of receiving a **counterfeit or refurbished part** that may not function correctly or could even damage your receiver.

4. **Labor Costs** If you re not comfortable with electronics, hiring a professional to install it could add **$50 $150** in labor fees, increasing the total cost.

5. **No Performance Upgrade** Unlike some aftermarket power supplies, this is not an upgrade it s a **like-for-like replacement**. It won t improve sound quality or power handling beyond the original design.

6. **Age of the Part** The **DX-C390** is an older receiver (released in the early 2000s), and some components may be harder to source in the future. This could become an issue if you need additional repairs later.

7. **Shipping Delays** Since Onkyo parts are no longer mass-produced, shipping times may be longer than for new consumer electronics.
