Wow. I didn't know about the SilentNight. Newegg sure loves Super Flower! Geez. :)

 

For anyone who's wondering, it's the Super Flower Golden Silent:

The whole issue more have to do with group-regulated design PSUs, where low loads on the +12v (in this case 0.05A) would cause the +12v to increase and go out of specs with some load on the 5v rails (the higher the load, the higher the voltages goes on the 12v). The thing is the load on the 3.3v/5v in this state more than likely isn't going to be high enough to cause it go out of specs anyways.

Edit: Here's where Corsair stated it btw (written by Jonny Gerow. You may know him from Jonnyguru.com) : http://www.corsair.com/us/blog/haswell-compatibility-with-corsair-power-supplies/

 

Whoa. Thank you, thank you, thank you! This is the understanding that I was looking for!

I don't know, but I feel that this PSU is overpriced. Its +12V capacity is only 648W which means it's really just a basically decent 650W PSU.

 

Here's a high-end 650W modular PSU for $99.99 shipped and $79.99 shipped after the rebate card:

 

650W LEPA G Series

 

Its +12V capacity is 648W.

Oh i'm asking because it's bought at around $50 before and I was using it as a back up. If it's compatible I guess I don't have to buy a new pSu for haswell. Just wanted to know if it is...

It sounds to me like the only way it will be compatible with the C7 state is if it has a DC-DC secondary instead of a group-regulated design. I don't fully understand what I just said though: I'm only going by what qwan456 said.

Hmm I see, here's a more practical question: is it safe to test C7 states using the power supplies or will it ruin components? If it's safe then I'll just test my current PSU before purchasing another.

That's something I don't know, so we'll have to wait for someone who does.

There is both an I and a G series. I spoke to CoolerMaster representatives just the other day. G series is higher end than I series.

CM said they haven't tested C7 compatibility on these yet, but they aren't expecting them to meet it.



Testing C7 states should not affect a PSU adversely in any way; if it fails it will either A. refuse to start, B. shut off, or C. present out of spec voltage and/or ripple. Component damage is highly unlikely.

I'm more worried about MOBO damage tongue.gif I might just test it then unless these PSu companies start releasing compatibility charts.

You can either wait for compatibility charts, or try to find out if it has a DC-DC secondary.
