Hx850/ax850

[Sem]

Im in the market for a 850w psu and i cant decide between the HX850 or the AX850

 

i already know the main difference between the two the only deciding factors would be the cables and the noise

 

which is the quieter of the two units under load

 

i know the AX850 fan doesn't spin up at low usage but from what ive read it is quite loud under load compared to the HX850

 

can anyone confirm this?

 

thanks

I guess that you don't have better dBA measurements than SPCR. :)

And TBH I'll always pick a Seasonic Gold unit in front of anything else.

What do you want to power with it?

I was about to post the same question ! Great minds think alike... was about to ask under load how is the noise also.....

 

Quite a few guys have suggested even under load there hx is quite silent... and doesnt seem bothered much when running powerful cards/overclocked systems....

 

heres the link just in case :

but this is regarding just the hx, I would however like to know why Corsair downgraded the fan from a 135mm silent fan to a 120mm in there newer AX models since surely 135mm is more silent/better airflow ?

 

my gutt tells me there was a noise issue perhaps with the hx series so they put a better quality 120mm fan instead in the newer ax series, but where can one find an honest Corsiar Worker ? :)

 

If anyone has had either, please let us know if its been noisy, or under load if the fan barely spins ? Thx

AX is a different design and only spins as needed. Also... size isn't everything :) Blade design, blade angle, etc all have effects.
