PCI-E Riser cable insight

So I recently bought a GTX 750 ti to turn my media PC into a little gaming box (it's actually powerful enough). However the case I made for it was never designed for a video card, hence the need for a riser cable.

Now I know the 750 ti does not require supplementary power which is one of the main reasons I bought it, plus my power supply is only 300 watts and it's the only card on the market that's compatible.

I ordered a cheap basic riser cable and tested it out, it works fine until I try to start gaming with it, drivers crash constantly and the occasional BSOD makes it impossible to work with, sending it back and I need to get a better quality one maybe like this: http://m.newegg.com/Product/index?itemnumber=N82E16812368001

Okay now that I put forth the information, I have a question regarding these cables. I noticed some of them are powered, and a few forums around tell people that powered cables are necessary for Bitcoin miners; blah blah blah.

Since I practically know nothing about risers, is a powered cable even necessary for a 750 ti to function properly? Or can I just use the basic extender? Surely since it's just extending the PCI connection it wouldn't need a powered cable anyway?

    The pcie slot actually has two slots in line with a divider , the small slot is power and the large is data , the adaptor you have must be data only, the deepcool is both, so should work.
    With the bsod when starting game, this could in fact happen if the gpu is not being fed enough power. but can be software related too, but power is my first bet.
    Can you link us to the first extender you bought, to checkout.
  2. I've had problems with the riser that came with my Silverstone FTZ01. Long story short, some riser cards/cables might not be able to pass through enough power to run your card. There may be other quirks as well. In my case, with a gtx 770 the drivers kept crashing if I tried to run the card in PCI-E 3.0 mode. Everything works fine in PCI-E 2.0 mode though. I imagine that the riser can't quite handle either the power or bandwidth requirements of PCI-E 3.0, despite being rated as 3.0 compatible. You might want to try this if you still can't get things working with the new cable.

    Anyway, good luck in getting your stuff working. Hope some of what I said helps.

    Heres the link, its SLIGHTLY more difficult to get computer parts than the States, otherwise i would've ordered the deepcool one from Newegg.com initially (its not on newegg.ca)

    theres a review on the same one I ordered that describes pretty much the exact problem I had with it, but i thought id give it a gamble.

    Interesting, I didn't know you could switch PCI-E modes. Is that built into the windows OS? Does it cause incompatibility issues or performance drops?
  5. I guess what it may come down to now is if even a good quality PCI-E Riser cable is capable of powering a 750 ti SC without supplement power (like on a molex)? For instance the DeepCool one i was looking at?

    You can't switch PCI-E modes from within windows. You have to do it in the BIOS. From what I've read, the performance drop is nominal. I don't think either the 750ti or the 770 saturate the PCI-E 2.0 bus, so it shouldn't be a problem.
