corsair ax 860w

[GlasgowBhoy]

Im thinking of buying a system with an estimated total wattage power of 451 watts and im wondering if the corsair ax860w power supply will be good enough but i may be probably going for 2 way sli in the future which will put it up to 616w

Yes it is better than good enough, a quality unit.

In that case you can pick a Corsair RM750 for less money, and still enough power for sli.

That's an excellent, truly superb PSU that is also very overpriced.

You can get this one much cheaper and it's almost as good if not better: http://www.newegg.com/Product/Product.aspx?Item=N82E16817438018

The wattage is somewhat overkill but if you plan on SLI'ing it's a very good choice. If you want the AX860 or AX860i anyway you won't regret it, but you can do basically the same for a lot less money.

EDIT: Just checked Newegg, the difference in price is apparently not that big anymore. You can probably get the EVGA cheaper elsewhere though. You can get the AX860 elsewhere a lot more expensive, that I know for sure.

thanks everyone , much appreciated

Yes and it's manufactured by seasonic, which is even better news.

Nope, this unit is low quality. Barely tier three. It failed most websites PSU tests and then all Corsair did was change a resistor to make it not shut down under heavy load which makes it MORE dangerous. DO NOT buy an RM750.

They have fixed this, also they didnt change the resistor to NOT shut down, but to start the cooling sooner, it still shuts down if necessary.

" 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."

The RM Series PSUs, like all Corsair PSUs, are designed and tested using methodologies that closely simulate the environment of an enthusiast/gaming PC under heavy, sustained workloads. Our testing has proven that the cooling system of the RM Series will engage and provide the necessary cooling during heavy real world use.

That said, we’re enthusiasts, too. We understand why Kyle and Paul came to the conclusions they did, and based on their feedback, we’ve implemented a design change that will allow our RM Series PSUs to go the extra mile and endure the extreme synthetic test conditions of the HardOCP test lab.

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.

Instead of using higher quality parts that do not overheat so easy, all the did was replace a fan resistor. This is what Corsair gets just a bad rep in the PSU world. Ridiculous.

The RM750 uses junk capacitors that get WAY too hit and fail WAY too easily. It stands that it is still not a quality unit and all Corsair did was band-aid the issue instead actually addressing the real problem with the unit.

As it stands, that is still a tier 3 unit at best. We do NOT recommend it.
