Difference between AXi and RM series power supplies from Corsair?

[legend8887]

I know the RM series is optimized for silence because it has a zero RPM fan mode, but the AXi series has that as well. Also the RM series has Gold efficiency, so is there a reason to get the RM series over the AXi series?

Platinum rating?

Yes it's cheaper and has sexy cabels.

Platinum rating?

Yeah but is there THAT much of a difference between Platinum and Gold?

Platinum rating on the AXi and the RM has Gold (Still very high efficiency) Also the AXi series allows digital monitoring of the PSU with Corsair Link.

No 3% max. That is on 100% load with 230 Volts.  80+ Gold is 89% efficent in this situation and 80+ Platinum is 92%.

Just get the cheaper one.They're both great. (unless you really need axi's features,which if you did then you would have probably known already)

The AXi offers longer warranty, better efficiency, better electrical performance (voltage regulation, ripple suppression, etc), better internal components (the higher 50C rating also reflects this), etc.

On the other hand, the AXi series cost quite a bit more (around $85 difference), and there have been complaints from people regarding the fan profile (though, not from everybody). For the price it is at, I don't see any reason to get the AX860i...

platinum efficiency

higher quality components than RM

more power options (1500i coming soon)

Different OEMs, way better performance from the AXi. Having said that, these are not things you generally notice so go with what you want unless you are getting this for benching.
