Corsair PSU not compatible with Haswell motherboard?

post #1 of 20
Thread Starter 
Hi guys,

I put together my PC on www.pcpartpicker.com to check for compatibility issues, and bump! I've come across one.

When I try to choose the PSU, I can't find the Corsair AX760i on the list. (I actually even turned off the compatibility filter, and still couldn't see it).

Could someone explain what's up? Thank you.


This is the hardware I am about the buy:


Intel i7 4770k

Gigabyte 2GB OC GTX 770

Asus Z87-A motherboard (don't really know why.. just couldn't think of anything better).

Corsair Vengeance 16GB DDR3 1600Mhz

Corsair C70 Case



Thanks again,

-Rich

No reason it wouldn't work. You'll be fine with that PSU.

Although you could get one just as reliable for a bit less.

Or these if the 80 Plus Platinum is what you want

Thanks for your quick response.

Those look very nice. I wasn't aware they all had interchangeable wiring - great! Are they silent however? I don't know much about Seasonic.

Unfortunately I'm over in Europe, so no newegg for me :\ This is the only "good" one available round my end. http://www.caseking.de/shop/catalog/Seasonic-X-750-Gold-Modular-Netzteil-Semipassiv-750-Watt::14166.html

Seasonic is one of the most reputable PSU brands. If you are buying a unit from a reputable brand they are almost guaranteed to be near silent. Nothing is guaranteed of course because the fan speed is dependent of the load on the PSU. However, with the system you are putting together you won't come close to the max power of that unit, even with a healthy OC. So it should stay nice and quiet biggrin.gif

Seasonic is a top-tier OEM of power supplies (in fact many of Corsair's units are built by them) and their X-Series line is excellent. It's also compatible with the new Haswell C6/C7 states that you were originally asking about.

Technically speaking, all the CX-line PSUs under 750w are group-regulated without DC-to-DC conversion for the minor rails, and thus aren't compatible with Haswell's C6/C7 states.

Of course, that is easily remedied by disabling said states in the BIOS...

Thx for your replies everyone smile.gif I might get a seasonic PSU then.. Dunno.

Anyway 760w is fine for my rig right? I thought 650w would be too little, so to be safe Im going with 760w.

Honestly as efficient as new GPUs and CPUs are you'd have plenty of power with a descent 500W. Go 750W plus if you think you might go SLI in the future.
