Tell me if this PSU can handle Cstates

post #1 of 6
Thread Starter 
Got a XFX XTR 550W. It says it is "Haswell Ready". Whatever that means.rolleyes.gif
It doesn't specifically state it can handle Cstates C6/C7. Anyone know if it can?

Thanks!

The new C6/C7 power states on the Haswell-Shark Bay platform will require the system power supply to be able to maintain a minimum current load of 0.05Amps on the CPU exclusive 12V2 rail (0.6W). http://vr-zone.com/articles/is-your-power-supply-ready-for-haswell-/19848.html?utm_source=feedly

Note the .05 amps.... or .6 watts... that is the killer!




per this review, minimum output (.6 amp) : http://www.tweaktown.com/reviews/6022/xfx-xtr-550-watt-80-plus-gold-power-supply-review/index.html

XFX wesite
http://products.xfxforce.com/en-us/Power_Supplies/XTR_Series_550W_PSU/P1-550B-BEFX and shows that the minimum 12V output is (Min -12V Output Current (A) : 0.3) . Not the .05 amp standard for Haswell....


So no.. it doesn't look like that PSU is 100 percent Haswell C6/C7 state compliant.... based on the standard of minimum 12V .05 amps needed, versus the actual 12V .6 amps or .3 amps shown.



Interesting writeup: http://coolermaster-usa.com/press_release/haswell/haswell.html

From this writeup June 4 2013... http://techreport.com/review/24897/the-big-haswell-psu-compatibility-list
XFX
Here's the word from XFX on Haswell compatibility:

XFX power supplies use a +12V design that allows for a minimum of 0A so they will not have an issue with the new low power sleep states allowing the CPU to enter deep sleep mode without any problems. XFX manufacturing partner Seasonic in conjunction with Intel have worked together to confirm that all XFX Pro Series PSUs listed below are compatible with Intel's new 4th generation Core processor family for new CPU upgrades to current systems and future new builds.

And here's the compatibility list:

Pro Series Core Edition: PRO650W, PRO750W, PRO850W
Pro Series XXX Edition: PRO650W, PRO750W, PRO750W, PRO850W, PRO850W
Pro Series Black Edition: PRO750W, PRO850W, PRO1050W, PRO1250W
Pro Series Black Edition: Limited PRO1000W

The firm adds that its XFX Pro Series 450W and 550W units are not Haswell-ready. However, XFX is "working closely with Seasonic to develop a new 550W Gold Pro Series PSU that will be compatible later this year."

Maybe so, but what more is there to say? Holy cow. lol Nice work. I subscribed with the hope of learning the answer, and, well, I'd say that I just learned the answer!
