Am i going crazy? Are these two PSU's different?

[Flambard]

Hello everyone, 

 

Just want to start by saying thank you for the community and some of its members for helping me get to this decision on which PSU to purchase. 

Please see this topic for the help on choosing between Corsair RMx and HXi https://linustechtips.com/main/topic/1024129-stuck-between-two-psus/

 

I am purchasing the RM750x of amazon but there's two which have the same name look to have the same specs but the images and price are different and number of connections? 

 

First one:

Price - £125.26

Amazon - https://www.amazon.co.uk/Corsair-CP-9020187-UK-RM750x-Modular-Supply/dp/B07HFKST91/ref=sr_1_15?ie=UTF8&qid=1548093277&sr=8-15&keywords=psu%2Bcorsair%2B750&th=1

Corsair - https://www.corsair.com/uk/en/Categories/Products/Power-Supply-Units/Power-Supply-Units-Advanced/RMx-Series-White/p/CP-9020187-UK

Second one:

Price - £131.86

different model year probably

The cheaper one (on the corsair website) is a newer version.

It has 2 EPS vs 1 EPS and 1 Floppy on old and 9 SATA vs 8 SATA.

The rest is pretty much the same.

The 2018 version is also smaller (150mm vs 180mm)

Okay awesome so the cheaper newer 2018 one is technically better then the 2017 which is more expensive, great that works for me thank you!

Yup, just get the newer one. Btw the "old" one is a 2013 design.

Thank you! How did you find out that it was a 2013 design?

Go to my local price comparison website, see there are 2 rm750, one with the "model 2018" suffix. Click on the normal one, check price history and it shows that it was first listed in 2013.

I thought that the RMx was released around 2015? The Corsair RM which is a different unit again came out a few years earlier around 2013 I think. Maybe you're looking at the RM series and not the original RMx?

The earliest reviews of the RM are from 2013, and 2015 for the RMx. 

The 80+ reports for the RM are from 2013-14, and 2015/2018 for the RMx. 

So you're right.

Am I still correct in thinking the cheaper version RMx is better then the more expensive RMx? RM confusion aside? e.g. smaller, 2EPS compared to 1 and 9 SATA vs 8?

For performance, both are good. So if it has more of the useful connectors, then sure.

They're both good units. 750w and higher units are physically smaller on the 2018 version (I think about 15mm shorter from memory) and have slightly different connector count. If you need 2 EPS connectors get the 2018.

 

@Flambard the 2018 model (the shorter one) is cheaper, so go with that.

 

I actually had no idea the old RMx came in the white edition. I thought it was only the 2018 that got the sexy make over.

Awesome thank you both! I have now ordered the newer version can't wait to get it set up, i have a white Corsair graphite 780T case so should look quite nice. - Think im going to be downsizing case to the NZXT H500 for looks/weight and portability soon though. 

 

Also i see that you have the PSU already @Spotty how is it for you?

No complaints here. Nice and quiet.
