Corsair RM series

[ahmedecho111]

I am willing to buy a corsair rm series power supply but found that the rm 750 had thermal issues...i couldn't fidn the review of this psu on jonnyguru...but the issue is quite older and i want to know that if corsair has solved this issue now...

The RM750 with the thermal issue was an older revision, that got fixed within a few months of release back in 2013 (the week of October 13).

Current revision is build by a different OEM and based on a different platform, so you don't want to worry.

 

Can you provide a link to the store you are buying from? There may be a better alternative for you than the RM750

I can't Provide the link now but can u plz tell me some alternative in the same price range of rm 750?

Wouldn't use the new RMx series and possibly the RMi - system builders at work have found that the capacitors in the cables make the motherboard connecection end of the cable solid for about 1.5" meaning it'll stick up off the board before you can move it to route it.

Well, that would depend on your region. That's why I had asked for a link - to see what's available to you and for what price. When you can post a link, please do so, as it will be helpful if you live outside of the US.

 

Here in the US, the RM750 is $119.99 USD. You could get the RM750x for cheaper at $99 and that's a superior unit. You could get the EVGA Supernova 750 G2 for cheaper as well for $109.99 base price with a $20 MIR.

So which one should i buy rm series or the rmi series?And what's the difference between rm,rmi and rmx series psu?

The difference between the RMi and RMx is that the i version has an higher quality FDB fan, software monitoring with Corsair Link, switchable between multirail and single rail via link, and a fan test button. Other than that, they are based on the same internal platform from CWT using the same Type 4 cable type which uses extra v.sense wires and capacitors to improve voltage regulation and ripple suppression. They also offer a 10 year warranty and is rated for a more robust 50C.

 

The RM is targeted more toward the mainstream segment with a shorter 5 year warranty and lower 40C temperature tolerance. It used the older type-3 pinout, so it wouldn't have those caps and v.sense wires, but the lack of it does help with the routing of the cables.

 

I still would go for the RMx though, unless you find Corsair Link appealing. Here's a picture of my cable management (yes, I'm aware it's overkill, but I got it for cheaper than the 550w model and even then that's also overkill).

Spoiler

Hmm, I think I should re-route that SATA power cable.

Lol..  ok i will bother u again..  Some people are saying that the rm series power supplies are made with low quality capacitors and components...iS it true?

The RM series uses capacitors from CapXon in the secondary side. The RM750/850 had used Ltec in the first revision, but the change in OEM and platform had shown they had upgraded to higher quality Japanese capacitors. I'm unsure whether or not the AVL (Approved Vendor List) is just Japanese caps or a mixed of Japanese and Taiwanese/Chinese which there's some luck involve with the sample you get (which is understandable as the original RM series wasn't intended for the high-end segment).

They are not a bad unit but often a poor value.

I think the whole Ltec shenanigans were blown somewhat out of proportion. These capacitors were dealing with less ripple, and mathematically according to calculation their lifespan would be greater than 15 years when running 24/7 with PSU temps of about 44C-53C.
