I ordered custom cables and choose shipping method that should arrive between 6-12 days. Today is the 14th day and I have yet not received my order. They can not keep up with their promise and blames it on Chinese new year. I WOULD NOT RECOMMEND ANYONE buying from MODDIY.

Can't believe someone said "FAST"... I ordered a GPU power cable from MODDIY on Feb. 5th. Their website did inform that any custom item would not ship until after the Chinese New Year--but the item I ordered did say IN STOCK. On Feb. 25th I emailed them, where is my order? and they replied about it saying any orders not in stock during the CNY would not be actioned until after CNY --Feb 6th to 26th!! yet later that day I got an email telling me my item had SHIPPED. Okay--now today--March 7th!! I checked their website and it says my order is being PREPARED!! The real kicker is that when I ordered the item I include a note telling them I need this item and asking politely that they send it at the earliest... NEVER AGAIN!

I ordered some PCIE connectors to put on my damaged power cables. A week later and it still says packing? Now after ignoring me they say some chinese new year garbage will mean I must wait several weeks before it gets shipped out. They say the web site said I would need to wait several weeks. No chance it said that. It also is not a custom cable nor did it say out of stock. I would never use this garbage company again. They have no respect for their customers time. I have a rig down, it has been down for a week. Now I have to order from some one else. And since they are now once again ghosting me after demanding my money back I will have to go to the bank and demand a charge back. Which they will initially refuse so I will have to harass the banking regulators until they get sick of my voice and order the bank to do the charge back. Avoid this company like the plague. They are dishonest, and have no respect for their customers time. They bring shame to themselves but since they have no self respect, they don't care.

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.

Moddiy tried to slap on a hidden fee when cancelling my order. On top of that, it was troublesome to communicate with the customer service. While chatting it felt like they were stalling. For example, when I asked for clarifications on how to proceed with a refund, the chat was abandoned on their end in the middle of it

ModDIY claimed my intial review on trust pilot was not based on a genuine experience. Unfortunately, the email I received from trust pilot somehow ended up in my spam folder and I didn't see it until the last day. I sent the required information to Trust Pilot to prove that my experience was genuine and hopefully it goes through. If not, here is my review and don't worry modDIY, this time, I'll be ready to make sure my review sticks on this website, unlike your website, where you only select the good reviews to show. Anyways, the original review is as follows: This company is very selective of what reviews they show on their website. I had placed an order for a 90 degree adaptor cable for the new Nvidia 40 series GPU on 1/16/2023. I had left a bad review for them on their website for sending me the wrong product and for poor follow-up service. Please note, that I did not leave a bad review until after their poor response and service... I was using their chat to contact them and they had initially responded, seeming to express concern. However, when I had informed them that they had sent me the unsleeved cable instead of the sleeved cable, they immediately stopped messaging me back and for 2 days, and every time I messaged them, I kept getting message prompt: "We are very sorry, but all our agents are engaged right now. Would you please leave your question and email address here and we'll get back to you shortly." I had asked them if they would just send me the sleeve, as they had sent me the un-sleeved one, and I still had no reply. At this point, on Friday, 1/20/2023, I decided to leave a bad review on their website for their poor service. I still do not see my review on their website. This means that they are selecting reviews that only make them look good, and I find it highly unprofessional, that they would choose to contact me back to ask me to "take a picture," only after I had decided to leave a bad review. Bad practices and bad company. I do not recommend them.

I ordered a cable for my graphics card on their site. The product page clearly stated it was compatible with my series of graphics card. However after ordering i inspected the corresponding connector on my graphics card one more time and realized that it wasn't compatible because there are two different kinds of connectors this series of card can have and their cable is only compatible with one of them. Of course there is no disclaimer on their product page about this. Anyways, just a few minutes after i ordered i tried reaching them via live chat and email to cancel the order. The person doing the live chat support magically went offline right after i asked them to cancel my order and i didnt receive an email until after the package was shipped 24 hours later, basically telling me: "Tough luck. Your package has already been shipped."

Ordered 4/25/22. Debit card charged same day. Web site says shipped USPS on 6/1/22 from Hong Kong. No way to contact on web site. Emails just get auto response. Save your money and buy American. They sell on Google so you can't see they are Chinese Bandits til the get your money.
