Product Review Tips:

  • Be real – We and our customers want honest reviews, so tell others the good, the bad, and all the in-betweens.
  • Get detailed - Sure, saying that an item was “Good” or “Bad” is nice - but what made you feel this way? Include something that you may have wanted to know before you bought the item.
  • Stay respectful – It’s ok to be upset, but anything that breaks our review guidelines will be removed - so be sure to follow them otherwise your feedback won’t be seen.
  • Don’t mention price or shipping issues – That’s not the product’s fault.

Please allow 1 to 2 business days for the review to become visible.

Great product! Only problem is...
I would 100% recommend this PSU to someone else who needs a replacement or to build a PC. I love the price, but I have one question. Where are the cords? Before I purchased this PSU, I had a non-modular PSU and didn't have the cables for the new one I'd buy. I thought, "Oh, it'll come with the PSU." . . . It didn't come with the PSU. And I can't find anywhere saying, "Does not come with cords." I have one request, Rosewell. Can I get the cords? Please? I need it. I just used the rest of my money on this thing. I literally can't do anything with it. Thanks in advance for your answer!
