I had a compatibility question and they were able to respond lightning fast validating my purchase decision. Very responsive to all email inquiries and replies. I still haven't heard a peep from the OEM manufacturer. Will be revisiting for future needs.

I stumbled upon MODDIY when I needed a set of white cables for an all white build I just completed. I had a great 1000w PSU, but it was all black. I ordered a complete set of cables at a reasonable price, when considering they were built to my PSUs spec, and noticed they also offered the new 12Vx6 plug I needed for my new 5070ti. I received everything pretty quick and they work and look great! Where MODDIY excelled even more is with their customer service. I switched out my GPU, and unfortunately the retaining clip on the plug snapped off, and I was bummed. It still works, but the back plate won't stay on. I sent in an email and got a response same day telling me they'd ship an entire new cable free of charge! This was amazing, as working with companies like Asus in the past, they refused to repair anything, or take a multi week exchange of emails and calls to actually take some action. Thank you MODDIY, you're my new favorite company when I need something for custom builds :)

Five-star service, every time ⭐⭐⭐⭐⭐ Customer service doesn’t get better than this. Sure, their catalog is massive and search can be a bit “meh,” but tap the chat bubble bottom-right and a real human will help you find it, customize it, or build it from scratch. Friendly, fast, and clearly not a bot 🤝 I’ve ordered customized cables from ModDIY multiple times and they’ll continue to be my go-to. Lead times are quick, quality is solid. I did have one fan extension where the connector came off on first unplug, but I’m confident they’d have replaced it in a heartbeat if I’d asked. Humans make things—and they make it right. Highly recommended 🔌✨

Carrie from MODDIY was very knowledgeable and helpful. I am impressed with the product, seemingly no one else is providing such high quality custom power cables. Specifically the 12V2x6 H++ connector with premium high-current Single-Split 4-Spring (Leaf-Spring) terminals. Thank you Carrie and MODDIY for answering all of my questions and providing a premium product!

I made a mistake on the order but rather than sending me the wrong thing the company checked with me and I was able to correct the order. That is great service and I'm happy to praise their staff and give credit.

I ordered 1 PTM 7950 50x31 for my MSI laptop. The first cycles weren't exectional, although a reduction of the temperature. After 4-5 cycles, my laptop still like an iceberg: frozen as ice. I struggled for 2 years to fix this up, nothing worked. This material saved me and my little baby. Shipping very fast, thanks for all moddiy!

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.
Dear Ivan, Thank you for your message, and we're genuinely sorry to hear that you're not satisfied with your experience. We appreciate the opportunity to clarify a few technical points that may help clear up the misunderstanding. First and foremost, a full refund has already been issued for your order, regardless of the cause. We always strive to support our customers with fairness and goodwill. Based on our communication, it appears that the cable you purchased—designed for PCIe 6-pin/8-pin configurations—is not compatible with your RTX 50-series GPU, which requires a 12VHPWR connector. These newer GPUs use a different power delivery standard, and unfortunately, the cable you selected is an 8pin/6pin PCIE cable. Regarding the pinout: PCIe cables typically have two distinct ends—the GPU-side PCIe 8-pin and the HP-side HP 10-pin. It seems you may have been some confusion between these two. For the HP 10-pin side, the standard configuration is 5 pins for +12V and 5 pins for GND. This is consistent and the same across manufacturers globally, including the cable you received from us. As for voltage specification, PCIe power cables are designed to deliver only +12V and GND. These are the only two voltage lines defined in the PCIe power standard. We’ve tried our best to explain these details patiently the difference of a 10pin modular port, an 8pin PCIE port, and a 12VHPWR port, but we understand that technical specifications can sometimes be complicated. It appears the cable was simply not the right match for your GPU. For over 14 years, we’ve proudly served customers worldwide with millions of cables sold, and we’ve never received a report of incorrect pinout in our products. That said, we always welcome feedback and remain committed to continuous improvement. If you have any further questions, please don’t hesitate to reach out. We’re here to help. Warm regards, MODDIY
Been ordering cables for my PSU. It's cheaper than getting the actual original cables. One time, they actually sent me the wrong cable, SATA instead of Molex. I complained and they immediately sent me the correct one, no extra charge.
