Overall Summary

Suspicious

Why 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

Failed

"A feedback score of 100 is not high for a seller moving significant inventory—proceed cautiously."

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

Failed

"Sellers regularly selling genuine SF850s do not price them even close to $22.50."

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

Failed

"Buyers cannot return the item for any reason unless invoking eBay Guarantee—not standard for expensive tech."

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

Failed

"Only buy if you can vet the serial number with Corsair and confirm all packaging and label details."

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

Failed

"Buyer must verify all details independently. No positive evidence available."

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

Passed

"Do not pay off-platform. eBay Money Back Guarantee is robust for eligible scenarios."

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.

Your Next Steps

1

Compare the product photos from the listing closely against official Corsair images and known reviews to check for differences in packaging, labels, and contents.
2

If you already bought, check the serial number with Corsair’s support or website to verify authenticity.
3

Keep all communications within eBay and only pay via eBay’s checkout system (PayPal, credit card, etc.). Never send money outside the platform.
4

If anything feels off or if the item is not delivered or is counterfeit, open a claim through eBay’s Money Back Guarantee right away.
5

If you have doubts, consider buying from a verified retailer despite the higher cost.
