Good tester for USB3.0 A/M-M cables (for risers) ?

[charles2k]

Could you recommend me good tester for USB3.0 A/M-M cables? Inside are 9 wires - http://imgur.com/a/KGTcM

Recently I bought big quantity PCIE USB 1-16x risers from China and I have trouble with them. If more than one card in the rig it is not hashing only pcie errors. When I replace USB cables it works ok. Previous batch from the same supplier was ok.

Just take a multimeter and see if you have conductivity with both ends

Well pay then to someone. In every case you need to test one by one.

I just ended up throwing all the Chinese cables away and buying some off amazon. I got tired of troubleshooting things only to find out it was a crap cable the entire time. The extra $9 per 2 GPU pays for itself in no time at all. Also im sure if you contact a supplier and tell them you need 1000 cables you will get a better deal. Below is what I bough

Just keep a few known good cables on hand and when you think you might have a bad cable swap it with the known good cable.

It is strange. With Asrock H81-BTC Pro MB it seems it works with this "bad" cables and also it is working with more cards in the rig.
But with Biostar TB250-BTC and GTX1060 cards it works usually only with 1 card, with 2 cards max. 10 minutes, with 3 and more only pcie errors. But with other (good) USB cables the same risers work ok also on Biostar...
Tested aprox. on 60 cards.

But a lot of cables from Amazon are also manufactured in China. And I buy whole riser with/cables cheaper than this Amazon cable, it is very overpriced.
