USB Risers were introduced after I started GPU mining so I never used them but I never had a single issue with the ribbon risers.
And yes you can get them cheap from China but it will take 3-4 weeks to receive and by that time ETH mining might not be profitable anymore. If you buy from Canada you would get it in a couple days even.
I once even bought a riser locally at a huge inflated price of $20/each because everyday that the GPU was unplugged, was $10 of losses per day.
Time is money also
It took me 1-2 weeks so far (or would be less if you buy a big lot and get same week shipping) but sure. Regardless;
They're still available locally in Canada at 6-8$ each from retail. I'd buy those before buying ribbons ones at 10CAD, but either way, i'm not in desperate need. But i do use them when i run out of USB ones until i receive the USB ones.
Anyhow i've sourced enough for my immediate use. Thanks to those i've dealt with so far. But i will need more soon, so i'll continue buying at a small markup over China. Just not 500% markup.
Getting the frames is much harder than the risers, alas.
I didn't get it, his shipping estimate ran up to 40$ and from the US it would take a while to get here. Still a good price but, meh.
