Thanks but I can't get an EVGA PSU in India (except for special imports)

Here we have a choice b/w (most) PSUs from Corsair, Cooler master ,(some from) seasonic ,antec and local players like zebronics,circle tech and xpro ( I agree all of which should be avoided ) to get  a sense of what's available look here :https://www.theitdepot.com/products-PSU+(+Power+Supply+Units)_C14.html

 

FYI : looking for 700-750w(modular is a bonus I don't mind if its not)

Looking at prices you have 3 options:

 

The 620W S12II for Rs 6065 https://www.theitdepot.com/details-Seasonic+620W+Power+Supply+%28S12II-620%29_C14P7878.html

The 650W RMx for Rs 8935 https://www.theitdepot.com/details-Corsair+RM650x+650W+Fully+Modular+PSU+%28CP-9020091-EU%29_C14P25857.html

The 750W M12II for Rs 8950 https://www.theitdepot.com/details-Seasonic+M12II+750+Bronze+750W+Modular+Power+Supply+%28SS-750AM2%29_C14P22805.html

That M12II is mighty sexy - the higher wattage M12II units are quite good for what you pay.

Thanks guyz so m12 II It is ... My local retailer + buddy  says he will deliver it by Sunday

Alrighty, enjoy your PSU!

I wonder if this PSU is fine to power an i5-6500 + R9 Nano + SSD. Pcpartpicker says it's fine.

120W for the system
175W for the Nano

It's a tight fit - look at at least a 430W one

Any word on the new CXM units yet?

They're better than the lower-wattage M12II EVO (520/620) but worse than the higher ones (850)

They're perfectly good units and recommendable.

I want to look at reviews T_T

 

On a happier note I found them in my country for the same price as old CX.

I'm going off of what quan told me. From what I understand they're comparable to a Seasonic M12 but slightly worse quality.

Corsair Vengeance is a German-fied version of the new CXM, so you could get an idea of how the platform perform electrically here

http://www.hardwareluxx.de/index.php/artikel/hardware/netzteile/38397-corsair-vengeance-650w-im-test.html
 

Of course, it's ideal to see a review of the actual CXM unit, but that's the best you can do atm. At the very least, I hope this can put the FUD with using these new CXM units with higher-end GPUs setup to rest.

 

Efficiency @ 115V : 86.9% | 88.3% | 84.2% - In the operating range of which most people will put the unit in, they will be achieving silver efficiency.

Load Regulation | Ripple Suppression - 3.3V : 0.3% | 21mVpp; 5V : 0.2% | 36mVpp; 12V : 0.6% | 22mVpp

All of the rails had stayed within 2% of nominal.

 

The difference between the Vengeance and the CXM is the AVL (Approved Vendor List) for the secondary capacitors are all Japanese (CX has both Japanese and Taiwanese/Chinese) and multi-rail on the Vengeance.

 

Now there's a few test that hasn't been shown.

Crossloads - A test to see how the load on one rail will affect the voltages of another, in which a group-regulated design must stayed within a certain ratio for it operated optimally. You could get a near 0% deviation with an ideal load scenario, while that same sample can have a 3%+ deviation in another as you can see with the CX600M. Since the new CXM are DC-DC regulated, this typically isn't an issue and had Hardware Luxx tested for this, it would likely had stated within that 2% nominal as well.

 

Transient Load Response, which is a very important test, as it determine the PSU's ability to maintain its regulation during dynamic loading like how it is in the real world. While it being DC-DC regulated to some degree help with this, transient loading is more determent on the primary side. As such certain topology such as ACRF typically doesn't do too well as you can see with the EVGA Supernova GQ 750w review. Since both the Seasonic S/M12II-B 380-620w and the new CXM both utilized the double-forward topology, I would like to say the CXM would be comparable if not better in this category.

You're the best.

 

The units are still made by CWT right? Just with the same topology as S12II

CWT but a better platform (not the S12II platform :D)

So I just built a server that is functioning as a NAS / Teamspeak / dedicated game server rig. Currently I am using a CX600 (I had it already for use in a test-bench cause it was $20, and just needed something temporary in the server) Anyway, running my server 24/7 on a CX600 is concerning, so I would like to get a good PSU for 24/7 use without going too high for budget (nothing like a 650g2 as that would be really overkill). Only things using much power are a Skylake Pentium and 8 hard drives. Any suggestions?

A Seasonic M12/S12 (whichever can be found cheaper) or Antec Earthwatts.

If the server has no GPU, perhaps one of seasonic's 350-400W power supplies will be enough? I'm not sure how much power 8 hard drives will consume.

each HDD is 15-20W (depending on the model) so I'd say a max of 160W + 120W for the CPU, RAM and anything else for a total of 280W max load (under extreme stress) so 350W is fine

Yep, I was thinking an S12/M12 cuz they're so damn cheap for what you get.

They are all HGST Deskstar NAS drives. I was thinking 350w or 400w at the lowest end as well.

From what I can find that looks decent it seems you are right about the S12 being best for the price. The S12II 430B is $54 and the S12II 540B is just $2 more.

The M12 is often the same price or less. If you can grab it for said amount of money then go for it.

Go for the 540B so as to re-use it later on if you build a rig with a GPU

Right now that M12 is $15-20 more so thats a no-go.

For $2 more that was my thought exactly.
