I'm looking at reviews for the RM PSU's from Corsair and they dont seem to have been reviewed very well.

However, I must add here that I didn't feel comfortable with the fan engaging as late as it did, and I would prefer it to spin up earlier to protect sensitive components, like electrolytic caps. I also don't agree with the caps choice Corsair made, since they went with Ltec, a brand with a bad reputation. I can understand the desire to keep cost down, but increased internal temperatures are part of the day-to-day routine in a semi-passive unit, and you absolutely have to be careful about the components going into such a unit.

Overall, Corsair has been one of the extremely solid brands we have seen and its products have developed a rabid following among enthusiasts. Certainly, a number of its power supplies have been a part of that. The Corsair RM750, however, is not one of those. Barring the fact that this unit is an outright failure as it is today, this unit was just not good compared to the competition including its own internal competition. Sure, the voltage regulation, DC Output Quality, and Transient Load Test results were in specification for the tests it would complete, but the RM750 could not pull ahead of the competition in any category or even keep up with the competition in many aspects. If we couple that with some of the unknown and/or low end component selections in this unit, we quickly can see that, even if this unit had passed all of our load tests, there simply would be no reason to buy this unit as there better options out there. If an enthusiast wants a really quiet power supply, they probably are going to want one that at least is competitive with other products not the one that is bringing up the rear. So, if users are really considering this unit it would probably behoove them to consider some of this units competitors like the Seasonic G-750 or (if they must grab a Corsair unit) the TX750M or TX750 V2 before Corsair tries to kill those lines off in favor of this newer and lesser product. While rabbits apparently don’t lay Raisinets, Corsair has sure laid a turd with the RM750 in its current form.
 
Corsair psu's have gone downhill ever since they stopped using Seasonic as an oem. When you look at Superflower, and especially the EVGA (Superflower) units it makes the Corsair ones even less appealing.
 
Yeah, doesn't look good.
Still, my RM850 hasn't missed a beat and has never let me down regardless of the clocks I've thrown at cpu/gpu's. The only thing I hate are the flat cables... :mad:

Also owning a Superflower, I have to say that they rock :)

This tbh, i have one of the older HX 850 units made by seasonic. Bought sh over five years ago and it has powered 4 or 5 heavily oc'd sli systems without skipping a beat.
 
Still running an old Corsair VX450 which must be around 5 years old now and has never missed a beat but would be inclined to go with Seasonic, Antec or Superflower these days if buying a PSU. It's a shame Corsair let the quality of their units slip..
 
I had a Corsair unit made by Seasonic that died so you never know with PSUs..although I do agree they have gone downhill..maybe it's to do with them focusing more on cases and cooling now?
