I bought this adapter, as new motherboards usually have no PCI 32-bit slots more. In this slot, I wanted quality (and expensive) sound card X-Fi Elite Pro with breakout box installed my. But there is a lot when using this adapter card to beachten.Ich have the slot holder of this card removed, otherwise is not possible to install the sound card. In addition, I have made of wood (strip) an attachment because the bracket is higher by the adapter, and can not be fixed. A corresponding hole in the wood (slightly smaller than diameter screw) now allows the attachment of the sound card. The manufacturer should accompany this product, a sleeve, and a longer screw, then you can save yourself the tinkering. Since the sound card caused sits higher through the adapter, it may be that (in my microphone jack) is no longer the top socket accessible. For me, no problem, since the breakout box (on the table and is connected to the sound card) provides all connections. I have not installed the card in a PCI Expres x 1, but in my Fal in a (large) x 4 PCI Express slot. The sound card is running without any problems. What I've been looking forward beonders, is the support the company CSL. This company is highly recommended.
