So I'm building my first rig and just the other day ordered this psu which was on sale.

I'm still not sure whether or not I'm jumping on the first revision haswell or going with ivy bridge. But reading around I've read that a lot of psu's wont be compatible with haswell...

anybody know what the deal is?
Will this PSU work with haswell? Would there be anything I could do to get it to work?

The issue with power supplies and Haswell is they don't drop to a LOW enough voltage.

This is only going to impact cheap and older power supplies.

You'll also be able to disable the power saving feature with the bios of the motherboards to not drop to that level.

That's a high quality power supply - you'll be fine.

Just want to clear that up. Some power supplies used to have a minimum current draw on the rails to keep them running in spec. This should not be an issue with good modern power supplies

You power supply as said above is of VERY good quality and should have no issues.

I do not know how low the cpu will get, but even my FSP 300 watt power supply in my media center remains stable at 23 watts from the wall.

If you have a gaming system, the video card will also take some power :)

Sorry for the mistake - sometimes the brain knows what it wants to say but types the wrong thing.

Here's an article about the C6/C7 power state "issues".

I can NOT wait to see this kind of cpu in my media center. It spends lots of idle/light load times(but can I just randomly build a new system....hmmmm decisions decisions....).

I just want to avoid confusion was all.

The Haswell Celeron processors should be perfect for a HTPC - low power, efficient, higher end integrated video, low temp (hopefully) and just enough power.

thanks for all the input. I saw that there might be problems with some PSUs the DAY after I purchased mine, so I was a little worried.

I'll keep an eye open for mine on the list, and if worst comes to worst I'll just disable the feature.

Now I just need to wait until haswell's release, then a-building I go!
