Pros: I'm very happy with this device. I've been using it as part of my digital audio interface for a few weeks now. So far it has been flawless. I run an EVGA x85 mobo with a M-Audio 2626 interface. The on-board firewire used the same IRQ as my raid driver. That might be OK for external drives but it's not(!) ok for time sensitive ins-and-outs needed for music production. The SYBA card was the silver bullet for my audio lag. I have sub 7ms latency for instruments through the DAW to the monitors. Nice work SYBA.

Cons: Not the cheapest available. But I can't vouch for the others.

Pros: This has been a wonderful product. PSU installed in Cosmos S without a hitch. I've had not a hiccup with it going on two months. Plenty of power for my SLI. Xigmatek has a coustomer for life.

Cons: None.
