[TR] Corsair sheds light on Haswell PSU support, lists compatible units

post #1 of 23

If you were reading TR last week, you probably know about Haswell's new low-power state, which causes compatibility problems with some PSUs. When the story broke, Corsair said it believed all of its PSUs were compatible. However, it was still checking to make sure.

Corsair has now publisehd a full Haswell compatibility list. According to that list, all of the company's AXi, AX, HX, TX-M, TX, and GS units support Haswell, as do the CX750M and CX750. Lower-wattage CX-M and CX units are "likely compatible," as are all VS-series models, but Corsair says it's still in the process of validating those.

Source.

Good to know!

Also, SilverStone and Seasonic have also published information on Haswell compatibility (thanks to chuckula and Heighnub's comments with the links on the source article).

Presuming it's a SilverStone PSU, it should be compatible, since they state at the beginning of the list that all of their PSUs, even the past ones, are compatible.

Most recent and high quality PSUs should be compatible. For all others, I presume that the BIOS in most motherboards (at least the entry level ones, where it is presumed lower quality PSUs may be used) will ship with the lowest power state turned off by default so as to avoid any potential problems. On a desktop it shouldn't matter much anyway, the power savings in question are not really that relevant in terms of electricity usage, this is more important for laptops, where all power bricks will obviously be compatible. In any case, it's good to know that you can take advantage of this new feature and have a more efficient use of electricity, even if it doesn't make much of a difference in the power bill.

That's what i was thinking aswell, low power state doesn't use much juice anyway, don't know why we would need even lower rolleyes.gif

Intel just proving they can save you another $1 a year on power.

Thanks for this, I was wondering if my Seasonic platinum would support Haswell and now I know it does.

If I have to upgrade I won't cry too much. I got that thing for like 30 bucks I think.
