PSU tier list 2.0

[jimmysmitty]

I've had to RMA my Corsair AX650 as it refuses to power on every now and again. The unit is 5 years old and there is no newer version of it - if they can't replace it with the same type as per their warranty, what would be an acceptable (fully modular) equivalent in terms of build quality and performance? I believe the OEM of this one is Seasonic.

Thanks.

The AX line would have been their flagship line when you bought that. There is still an AX 760 and an AX 860 that are made by Seasonic. I'd assume Corsair would offer you a similarly high end unit as a replacement. I personally would be happy with an AX, AXi, ( unlikely since they will probably match wattage) or, more likely an RMi or RMx. The RM units use CWT as an OEM and they are both excellent.

Just a guess though. My one experience with Corsair RMA ( M65 RGB ) was very easy and painless.

For him the HX series would be the equivalent, they are Platinum rated fully modular non-digital.

@superninja, I doubt you will run into much issue wise with Corsair. My 570X had a bad LED and they just sent me an entire replacement for the LED and top I/O panel without any questions.

The problem is though that neither the HX nor the AX series now offer a 650W version (hence my question). With the RM being the next best thing, does it matter much whether it's an RMi or RMx? I'm also slightly worried that CWT makes both the RM and the CXM units, with the latter ending up somewhere in tier 4, far from any recommendations. Is there really that much of a quality difference between the two series?

His AX predates 80 Plus Platinum. It's an 80 Plus Gold Seasonic X platform. The current 760w and 860w AX are 80 Plus Platinum and based on the Seasonic Platinum series. The HX was discontinued for a long time but is recently back like all the previously discontinued Corsair lines. No reviews yet, CWT made but only 750 watts and up so far. The HXi is also only 750w and up.

The reason I asked for a thread is I forsaw this topic was going to be a little longer.
Anyways since the mods are fine with it , lets stick in this topic.

This is one of the 2 times I saw a broken AX, so that is quite unfortionatly,
Like anort said its based on a seasonic X platform , and that flatform was so good , it was the FIRST unit that got a 80+ gold certification , which is quite an achievement.

Cwt makes the OLD cx as well as the rmx /rmi units indeed, and the quality gap is quite big.
If you are talking about the quality gap between the rmx and rmi , nawh there isn almost any.
the rmi is a little bit superior with a fluid dynamic bearing fan (little bit more silent), and corsair link.
But I heard from people that the rmx is already dead silent, and corsair link isnt really worth it.

Last, What is your budget and country and system specifications?

He's not asking for recommendations he's just wondering what Corsair is going to send him and what he should be happy with. 😉

I actually forgot about the AX gold series. They were short lived.

 

[Deleted member 217926]

All the AX units except the 760w and 860w were/are Gold. You might be thinking AXi.

[Karadjgne]

Realistically, the only difference in an X unit and an Xi unit is the ability to sync with Corsair link. The plain units don't, the 'i' units do, otherwise as far as quality and output goes, there's no real difference between a new HX and HXi or new AX and AXi. OEMs might be different, platforms different, but ability is the same. So difference between an RMi and RMx is negligible, both are great units, but if you have no need for Corsair Link compatability, the cheaper option is the RMx.

 

[Sakkura]

The RMi has a better fan. Considering it's a replacement for an AX unit, I wouldn't be happy if they handed me an RMx unit. RMi would be more reasonable.

Does any know what tier these PSU are
Corsair - TXM Gold 550W 80+ Gold Certified Semi-Modular ATX Power Supply
EVGA - B3 550W 80+ Bronze Certified Fully-Modular ATX Power Supply
Corsair - CX (2017) 550W 80+ Bronze Certified ATX Power Supply
SeaSonic - 520W 80+ Bronze Certified Fully-Modular ATX Power Supply

corsair txm

You have no clue. I can't finds on the list. Is bit confusing for me

 

[superninja12]

list is outdated, the cosair txm is the best of the 4.

txm>cx550m>seasonic520w.

b3 is unknown.

 

[Karadjgne]

Yeah, Mebe not, I'd put that Seasonic about even with the cxm. Granted it's an older platform, and still group regulated, but there's absolutely nothing wrong about that unless you insist on having a full suite of c-states on a new Intel cpu. The b3 from what I've heard is basically the same as the B2, still a good unit, but built mainly for mainstream chassis, not enthusiast class. So TXM, CXM, M12-II are tier 2, the b3 is tier 3.

 

[Stigma311]

I found this few hours ago and want to know if correct I post haft of it since list bit long


Tier 1 - Best
Antec - High Current PRO*, EDGE*, Truepower Classic*, Truepower Platinum*
Bitfenix - Whisper**
Cooler Master - V-series (not VSM)**, MasterWatt Maker**
Corsair - AX**, AXi**, HXi**, RMi**, RMx**.
EVGA - G2**, G3**, P2**, PS**, T2**,
FSP - Aurum PT***, Hydro G***
Rosewill - Quark***
SeaSonic - All of PRIME series**, all of X Series**, Platinum** and Fanless** units
Super Flower - All of Leadex** (excluding Silver)

Tier 2
Cooler Master - VSM-series (Not V)**
Corsair - Grey CXM**, HX** and other RM** units
EVGA - 750/850W B2**, B3**
FSP - Dagger SFX**, Aurum Pro***
Rosewill - Capstone G***
Riotoro - Onyx
SeaSonic - S12G**, SSRM (G Series)** and M12II EVO**
Super Flower - Golden Green**, Leadex Silver**

any way if you want to see this list at https://vozforums.com/showthread.php?p=119054861

Like i said like to know if this is correct since list says 2017

 

[turkey3_scratch]

^^I don't see how they rank an item like the EVGA B3 without it being tested and having unknown quality. That is a majorly flawed list. The Rosewill Quark has enough problems like noise where it should be lower down also.

I can't stress enough how much people should really do their own research, because if everyone takes the word of some other person on the Internet but if their research is insufficient then problems arise.

Another flaw is having Antec EDGE and TPC in tier 1 then SSRM in tier 2. For all I care, both are the same damn PSU.

Cxm and Evga b2 same tier? It'd have to be a 3 tier list, good-ok-ugly. However, saying an M12-II/G's are worse than a B2 is a stretch, unless the author has some funky views on group regulated designs, knocking down a peg for that.
Rosewill Capstone G is tier 2 and tier 4?
Consider that list bunk...

I generally look down on group regulated designs today, everything crossloads the 12V rail, it's so much better to have DC-DC.

4 reasons why dc dc is better.

What are the benefits of the DC-to-DC converter design?

High compatibility with zero minimum loads on each line.
Better cross regulation.
Maximum capacity of the 12 V current for extreme utilization
Higher efficiency and better dynamic response.

 

[Karadjgne]

So by your reasoning, a new CXM is better than a older Gold rated AX? Not that the older Gold AX weren't group regulated, better efficiency, etc etc etc. DC-DC vrs group is only really applicable when comparing like psus. I'd still be more trusting of a Seasonic built M12-II over a CWT built CXM on a pound for pound basis, even if technically the CXM is slightly better.

The gold AX850 here is DC-DC http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story4&reid=197

 

[Karadjgne]

80+ Gold AX 1200 was group regulated, as was the old Bronze equivalent HX 620, best psu's of their generation. I did say 'OLDER' turkey...

The HX power supplies made by Seasonic were unreliable, with really bad RMA rates. And I doubt that AX1200 is group regulated, where does it say it in the review?

Edit: That AX1200 uses DC-DC, see the internals http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story4&reid=189 - VRMs used for the minor rails.
