If you use an external drive (connected by USB 3.0) plugged into system while it is in a low power state (S3 sleep), the system may not recognise the drive on resume. If you keep your OS on a flash drive, or keep an external drive attached at all time that uses USB 3.0 then I'd hold off on buying a Haswell board and processorOkay, have not pulled the trigger on the haswell stuff yet. I bought all of the other gear but I am reading a lot about the problems Haswell is having right now. I will be using a lot of USB 3.0 stuff and that is one of the issues it is having
Blown out of proportion. IF you enable low power (and power saving in the OS) C6 / C7 states in the UEFI then you'll need a zero-load rated PSU since the system draws pretty much no load in the C6/C7 state. Not having a zero-load PSU means that the system likely wouldn't resume from sleep and would need rebooting.I had already ordered the PSU and that is another issue Haswell is having. If it is not a CERTIFIED Haswell PSU you may run into problems. I had never heard of that until I did some reading first. Crap, what is everyone's take on this stuff???
I think you should have went with my suggestion of a reliable PSU. Like I said, I have been building workstations for years.
That list doesn't seem that up to date to me. The Antec TruePower Quattro are on that list for example, and is Haswell approved.
It is a little outdated but still you can get some good ideas from it. Not for Haswell though, so for that, it is really outdated.That list doesn't seem that up to date to me. The Antec TruePower Quattro are on that list for example, and is Haswell approved.
What PSU do you have?
And as GhostRyder mentioned, disabling C7 is very much an option even if the PSU isn't certified for zero load.
The USB3.0 card reader would be more of an issue. If it connects to the motherboards internal USB 3.0 header then it could be affected. If the card reader connects via other means (usually a SATA port) then you will be fine.
