Check before use cables!

I want to share my experience with ModDIY, so others don’t face the same issues.On September 16, 2025, I ordered two “10 Pin to 8 Pin + 6 Pin GPU PCIe Power Cables for HP ML350 Gen9” from ModDIY. The seller explicitly guaranteed these cables are “original and correct for ML350 Gen9.”The facts:The cables I received were miswired. Instead of the correct HP pinout (3× +12V and 4× GND on GPU side), ModDIY’s version forces 5× +12V and 5× GND.Even their own product photo reverse-searches to a cable for DL380 Gen8/Gen9, not ML350 Gen9.Multimeter tests show completely wrong behavior: 10.5V on pins that should be 12V or GND.After connecting the cables, my HP GPU Power Backplane (P/N 780968-001) was physically damaged. The logic IC 74LV165AD (U1) burned out.Evidence:ModDIY’s own chat: instead of accepting responsibility, they aggressively denied any problem, insisted their cables are “100% standard,” sent random Amazon links as “proof,” and finally told me: “Please cut the cable in half and send us the photo, then we will refund you.”This is not professional support — it’s a clear admission that returning the item is pointless.The result:The cables are not as described.They damaged working HPE Server hardware.ModDIY refused to cooperate properly, denied evidence, and acted aggressively.Replacement of the backplane costs ~€100 incl. VAT and shipping (serverShop24.de). Together with the cables, my total loss is around $250 USD.Conclusion:ModDIY sells cables that are not what they claim, can destroy expensive hardware, and their “support” is unprofessional and hostile.I strongly recommend avoiding them.All evidence (photos before/after, multimeter measurements, chat logs) is available and can be provided publicly.Update after MODDIY’s response:MODDIY’s cable had the wrong pinout, proven by direct testing. It caused a burned backplane on my HP ML350 Gen9 — real damage that they never compensated for. Their “14 years of experience” means nothing when their product destroys hardware.They shipped a faulty, dangerous cable and refused responsibility. Never trust them.
