Corsair has been switching PCB manufactures lately. Try to get seasonic of you can.

how long have you been using the psu?

how long have you been using the psu?

 

Considering how the RM series was release in October-ish of 2013 not long enough to see if the cons will be an issue.

 

If the issue with the RM650 you heard about has to do with Oklahoma Wolf's review at Jonnyguru.com regarding two of the +5v wires not working on the 24-pin, then that's a non-issue. As Wolf had said, on a modern day setup, the amount of current passing through the working wires is high enough to affect reliability and performance. Even if it does, that issue had already being address before the first shipment of the RM450-650 had been sent.

 

Anyways, from a performance and quality standpoint, the RM series isn't on par with the other high-end unit in the same price point (at least the price point here in the US), in which I personally would recommend one of those over the RM series. The RM series isn't a terrible unit though and is a viable option if you are looking for something to power your system that is quiet and fully modular.

Oh, in your initial post, you mentioned the RM550 about bad reviews.

 

Anyways, the major problem with that review sample that [H] had found is that the unit got dangerously hot, and despite of that, the fan did not turned on causing a protection (OTP) to trip and shut the unit off. It was a considering issue that I had been worry about when seeing the review initally at Techpowerup.

 

However, it is because of that review, Corsair had address that problem and came up a fix a few weeks later. All unit that had made after 41st week of 2013 (after October 19) should have been fix. Since it has been nearly four months, the stores inventory should be stocked up this unit, so the shut issue shouldn't be an issue.

 

The other issue that had been discuss numerous of times is that the RM series uses low quality caps, in which many people are worry about the longevity of them. It's a legitimate concern; however, Corsair is confident that the caps will outlast its 5 year warranty even if your were to run it 24/7 at full load, which you more than likely won't be doing.

I'm running a couple of RM series since I've had a lot of issues with PSU coil whine in the past and I've had no such issues with the RMs. They're quality units.

not necessarily, RM PSU are a mid quality/range PSu designed to specifically not have coil whine or make any noise for that matter

No, the RM doesn't provide you the ability to turn-off "Zero RPM" mode and have the unit actively cool at lower loads.

 

A possible option you can consider is the XFX ProSeries 850w Black Edition. http://tweakers.net/pricewatch/362104/xfx-pro-series-full-modular-edition-%28gold%29-850w.html

Like the Corsair AX860, it based on the higher-end Seasonic KM3 design but doesn't meet platinum efficiency and does uses a lower quality fan.

those are more expansive i will got with the rm 850W. going to buy a new pc in 5 years anyway.

Just keep in mind, if you get a nice, durable PSU now, it will last you 5-10 years and through many builds.

That's exactly what I was saying: I specifically purchased them to resolve my coil whine issues with previous power supply units and they've done a great job in doing so.
