Which is the better psu the Corsair 650W rmx 2018 or the Corsair 650 rm 2019 ?

The RM (2019) is a cheaper version of the RMx (2018). Based off the same platform but the RM 2019 is designed to meet new energy efficiency targets that system integrators will need to meet for their systems in the state of Cancer (may cause California). It does this with a newer LLC resonant controller which boosts efficiency at low loads. Since it's targeted at system integrators it's also had a few cost cutting measures to keep the price lower. Cheaper fan, cheaper hold up capacitor, cheaper cables (without inline caps).

 

Quote

The RM650 uses an upgraded platform, provided by the same manufacturer (CWT) that made the RM650x. There several essential differences between those two platforms, as you can see in the table above. The areas where the RM650x wins are the higher quality Japanese caps and the NR135L fan. On the other hand, the RM650 uses a new resonant controller, allowing for higher efficiency under light loads, and it is equipped with an electromagnetic relay which enhances its inrush current protection. On top of that, it uses a micro-controller in the fan control circuit so Corsair can easily tune the fan's speed and provide the ideal fan speed profile.

The Tom's Hardware review linked also has a side by side comparison of the components used in both the RM 2019 and RMx. Though from the components listed (and lack of relay bypass for the thermistor) that appears to be comparing to the older RMx not the 2018 version.

 

Both are fine and neither will blow up your system, but the RMx is the better of the two if you aren't required to meet those low load efficiency targets.

There's more to a power supply than how many watts it's rated to deliver and what its efficiency rating is. There is a difference between the two units and they did not just scratch off the x from the label and sell it as the RM (2019). This also wouldn't even make sense to do financially since the RM (2019) MSRP is $10 lower than the RMx (2018) so by your reasoning they would be releasing the same power supply at a cheaper price when they could just keep selling it under the RMx (2018) branding at a higher price. 🤷‍♂️

I don’t  whether a Corsair rmx 650w 2018 is better than the Corsair rm 650w 2019

RM650x is a step up from the RM650 (w/o an X).

Yes but the rmx is 2018 while the rm is 2019 and what your saying is the 2019 model which is newer is worse than the 2018 model

That just means what year it was released.   I hate when they do that.  But they do that to show you that it's the RM from 2019 as opposed to the RM from 2014.

 

RM does NOT REPLACE RMx. 

 

They co-exist in the market.

 

RMx was out, then they said, "let's make a cheaper version and differentiate it by removing the 'x'" and that happened a year later.

he's probably frustrated because he works for corsair so simple differences that he has to explain a lot are a little annoying

 

they're definitely not "the same thing"

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

How many watts do I need? ATX 3.0 & PCIe 5.0 spec, PSU misconceptions, protections explained, group reg is bad

I’ve just noticed the 2019 one has an additional connector opposed to the rmx model

Ah ok so I can do without even if I want to do a tiny bit of over clocking right

So I can do a bit of overclocking without the connector then right?

Ye the amount that you need that additional connector apparently would fry the cpu if

That is completely incorrect. 

 

All either of you guys need to do is read a review of each... which exist in ad nauseaum.

As in apparently if I were to overclock with that additional 4 pin connector I would have to really overclock to really see the need for it then the normal amounts of overclocking and live with out it

And of course one has an extra slot one doesn’t but both can overclock right just the newer one slightly more due to the additional slot 4 pin connector

You apparently have this misconception that "total watts" is the only thing that matters. 

 

I suggest you read some PSU reviews before giving incorrect advice to others. 

 

Have you ever read a PSU review?
