Another Corsair PSU is in the lab, commanding our attention. We already reviewed the RM750x and RM550x, so we couldn't leave out the RM650x. It promises the same high performance as its siblings, along with super quiet operation.

Full power at 49°C; Ripple suppression; Load regulation; Performance with transient loads; Silent; Compact dimensions; Quality caps; Fully modular; Hold-up time; Warranty

Single EPS connector; Short distance between peripheral connectors; No bypass relay in the inrush current protection circuit

Thanks to Corsair, today we'll be taking a quick look at the Corsair RM650x Power Supply. The RMx Series of PSUs, are Corsair's premium range of power supplies aimed at the high-end and enthusiast market. These power

80 Plus Gold certified; 100% Japanese capacitors; Fully modular cable management system; Rifle bearing fan; Zero RPM fan mode; Massive 10 year warranty

If you have the money for it, you won't be disappointed. Very reliable and high quality product from Corsair, would look forward to using one again.

Installed to my case with no issues, and powered everything with no problem whatsoever; Comes with every cable you need, and plugs into the unit easily; The packaging and product quality was top notch, and felt very premium

The $110 price point seems a little bit high; and for some odd design choice they split the 24 pin ATX cable into two separate connectors on the PSU side

I have lost quite a few PSU's to power outages & ageing caps. But out of all of them this one has the most accurate and stable power coming off all rails. Then to add a 10 year warranty on top of that. Highly recommended.

Very stable voltages across all leads when hooked up to my meter

None

I finally tracked down reliability problems to the first power supply. A couple of emails to Corsair, and the replacement was on the way. The replacement has worked very well for a couple of months now. Very quiet, and when I look at power reporting, it's very steady and smooth.

I was looking for a modular PSU to make cable management easier within my case. This power supply did the trick, and allowed me to easily manage my cables better. Comes with a little sticker too, which I obviously stuck right on the front of my case. Would power my system with Corsair any day!

An excellent very quiet power supply Easy to fit, the modular design allows just those cables which are needed to be attached, avoiding the jumble of cables on units with integral cabling. The cables are sufficiently long for use in large tower cases, but not too long to "clog-up" the case.

Great power supply, should handle most builds quite well

Good power supply, it being modular helps with cable management.

Looks great, no complaints. In my corsair 300c it's pretty quiet too. It was a close toss up between this and EVGA 750 G2 but happy with it.
