eBay Listing: Corsair SF850 Fully Modular 80 PLUS Platinum SFX Power Supply (Seller: thsentier)
https://www.ebay.com/itm/257253107928Why we think so?
This listing is for a "Corsair SF850 Fully Modular 80 PLUS Platinum SFX Power Supply" sold by the eBay seller "thsentier" from Nürnberg, Germany. The seller’s feedback score is 100, with 95 units sold, and 29 watchers at the time the listing ended. The listed price of $22.50 is dramatically below market value—brand-new units elsewhere are $179–$225. The item is marked as "Open box," and the seller does not accept returns. No credible external complaints or scam reports are found for "thsentier," but the price is anomalously low for a high-demand power supply, and the no-returns policy increases buyer risk. Always compare images, check feedback for recent negatives, and if you buy, verify the serial number with Corsair. Proceed with caution— while the seller shows some basic legitimacy markers, the price and lack of returns are strong red flags 🚩.

Detailed Checks & Insights
0-100 Scale
Seller feedback and reputation
Score: 60
Seller feedback and reputation
Reason: The seller shows a 100 feedback score with 95 units sold, but this is a modest volume for electronics and there is no evidence of sustained, long-term reputation. No major red flags, but not enough for total trust.
Unrealistic pricing or offer
Score: 10
Unrealistic pricing or offer
Reason: The listing price is over 85% lower than any major retailer. This is a classic warning sign for scams or counterfeits.
Return and refund policy
Score: 40
Return and refund policy
Reason: No returns accepted, removing a meaningful buyer safeguard for a high-risk category. eBay's guarantee is a last resort, not a replacement for reasonable returns.
Authenticity and product consistency
Score: 20
Authenticity and product consistency
Reason: Price and volume are inconsistent with official Corsair channel sales, suggesting gray-market, fake, or suspicious inventory.
Seller external validation (third-party, search, complaints)
Score: 50
Seller external validation (third-party, search, complaints)
Reason: No external scam reports exist, but the lack of positive coverage or identifiable business history is a drawback. Most confidence instead relies on eBay buyer protections.
Payment and platform safeguards
Score: 80
Payment and platform safeguards
Reason: eBay facilitates payment, and buyer protection applies if purchase is made using approved methods. Still, you must be proactive about documentation in case of disputes.
