Corsair RM750?

[Copyright]

I know these units had issues a while back and Corsair said they fixed them. Anyone seen any tests on the newer units? The price is great for a 750 and love the fact it's zero rpm fan under 40% but is it a good power supply?

Even if they fixed the fan issue, the RM750 was not a competitive product. However, Corsair has started shipping a different platform in the RM series without so much as a peep that they changed the platform. I have no idea how to tell them apart as Corsair seems to just be calling them RM750's on the packaging (probably by serial number but good luck getting Newegg or Amazon to tell you the serial number) or if the new units are any better. I would simply look at the plethora of other options that can be reliably identified and whose performance can be referenced.

Editor's Note II: Corsair has verified changes made to RM units that would address the shutdown issues we experienced. These changes would very likely earn the Corsair RM series at the very least a "HardOCP PASS."

We have changed the value of the resistor between the thermistor and the fan controller so the fan turns on much sooner than the temperature that would trigger OTP. Therefore the fan should always turn on before OTP is triggered; preventing the PSU from shutting down before it is necessary.

This change has been implemented in all RM PSUs produced since mid October. While we honestly believe even extreme users will never run into the issue encountered during HardOCP’s synthetic test, those end users that want to know if their RM can endure HardOCP’s torture test can identify the updated PSUs by a lot code of 1341 or higher.

That issue has already been addressed a long time ago. All retail inventory at this point should have a lot number later than 1340. If you get a unit from Amazon or Newegg, it will surely have the fix implemented in it.

Thx, I will check the lot number tonight. I just bought it couple weeks ago so hopefully it's a good one! The system doesn't need a full 750w PSU so I am hoping the fact I will only be loading it with about 500-550W the PSU will work for me.

The number that the Corsair rep. told you, was referring only to the fan problem, that Corsair claims that solved it a long time ago, so to look if your PSU has a lot code >1341 is pretty much useless info in my opinion.
What is important, is the Corsair rep. to tell us what serial number should be looking for, if we want to buy the new RM750 (*build quality speaking), which has, -in theory at least, because i've seen no reviews so far-, superior build quality from the previous RMs 750.

Corsair hasn't changed the name for this upgraded version of the RM750, so the customers have to look at serial numbers, in order to to find out which version they bought !!

I'm a bit lost here. I don't think that there is an "upgraded" version of RM750, I don't even know what that means. We implemented the OTP fix in the later batches (1341 or higher) and that's about it.

This is what he would be referring to:
