AX vs RM series (psu)

[Diego Farras]

Hi, I'll try my best to explain my doubt

I need to know whats the difference between both, ax and rm corsair psu series. Specifically between:
rm750 plus gold vs ax760 plus platinum

I know that only the second one is fully modular but I understand thats not very important, no?.
So my question is: when or why it's better gooing for the ax series? I mean, does the performance justify tha price of the 760?

PS: I don't plan to overclock my PC (I don't know it that's important on this issue xD)

the both are good ...just take the less expensive one

It's quite important if your a uncluttered person to have a full modular. That makes sure wires don't get tangled all over the case.
Difference between 80+ Gold and 80+ Platinum PSUs are the quality and reliability. Platinum is the best, and Gold the second. If you need high quality stuff, go with the AX760, if not really then the RM750 would be fine. If you don't even need that stuff simply because you need the wattage, a CX750 or CS 750 is fine.

EVGA g2 750w - Better performing than AX, better built than RM

But I thought the only difference form platinum and gold was the efficiency, and between rm and ax the ax is fully modular. Am I wrong¿?

In terms of power supply both are equal?

Corsair doesn't actually make PSUs they just re-brand them. The RM and the AX are made by different companies. The RM is made by Chicony Power Technology, and the AX you are looking at is made by Seasonic. Seasonic is arguably the best PSU maker in the industry right now. The RM, while still a decent power supply, doesn't go to the level of quality that the AX does, specifically with its capacitors. The RM has some lower quality integrated into it while Seasonic built AX uses higher end materials.

The RM also has a 5 year warranty while the AX has a 7 year.

Difference between Platinum and Gold is reliability and quality. CS, CX, RM, AX, etc. for Corsair brand are the 80+ ranking. RM and AX have different 80+ ratings, and which AX is better.

They aren't really equal.

That first bit is inaccurate. The difference between platinum and gold is ONLY efficiency. You can have a high quality bronze unit with fantastic parts giving great Vreg and ripple suppression that will last for 10 years but is low efficiency because of its topology, you can also build a gold level unit with a very efficient topology but put low quality parts in it so it won't last very long. The Cooler Master Silent Pro Platinum is a nice example of this, Platinum rated unit, pretty good Vreg, but rather poor ripple suppression and poor capacity selection. Just because many fancy cars are fast, don't infer that all fast cars are fancy.

As for the question at hand, The RM and the AX series are built by different companies on different platforms, the AX/AXi is Corsair's flagship platform so you get excellent efficiency, fully modular, fantastic ripple suppression and voltage regulation, the RM is sorta a middle of the road platform, it still gives you good efficiency, great ripple suppression and voltage regulation, but you traded down on part quality to fit it into the price point for the target market.


It's important to realize there are only about 20 companies that make internals for PSUs and most of them don't sell PSUs under their own names. So when you see a Corsair PSU it isn't made by Corsair, it is likely made by CWT possibly Seasonic or Chicony.
