Power supply recommendation

[CalinTamaian]

Hello,

I am building a new rig and cannot decide on the power supply.

CPU: i7 - 4770k
GPU: 2 x 280x Matrix (375 W rated each)
HDD : 2x SSD Samsung , 2 x WD 2T
Case 4+ fans, Watercooling, some LED's for modding

I was looking into Corsair RM 1000 W (has pretty good the price/ performance), but saw a couple of
"bad reviews' and some concerns about the capacitor quality.

My other option would be Seasonic 1050-x.It is around 50 Euro more (150 E vs 200 E) so I am not sure it is worth it.

I also found EVGA SuperNOVA P2 (1000W) or SuperFlower Leadex (1000W) at around 190 Euro which are Platinum (opposed to the above 2 gold) but I have no experience with this manufactures. Any hints/tips?

I live in Germany.

Thank you.

Are you interested only for 1000 watt PSU ?
You are correct about the Corsair RM series. They have inferior build quality comparing with Corsair's previous series, and i wouldn't recommend them to you.
P.S: I think that the sites that you can acquire valid information for PSUs are hardocp.com, jonnyguru.com, and techpowerup.com

Flip a coin between the Seasonic and the eVGA. Those are going to be your best bet in terms of warranty, customer support, and quality.

I will go with eVGA. Saw a very good review on johnnyguru and the price beats Seasonic with around 35%. All doubts were removed when I saw the 10 year warranty ...

also HardwareSecrets and I certainly wouldn't list hardocp first (even if we are on its forum).

Personally, i lost a lot of faith at Jonnyguru, when i found out on a different site (* Techpowerup.com), that the Corsair 860i, were using some lower quality polymer CapXon capacitors.

At Jonnyguru there was no mention at all, so this troubled me a lot, because i was about to buy a 760i or a 860i, untill i noticed that and changed my mind!
Since then, i don't trust only one review from one site.

You have not been paying attention to those reviews then. In the TechPowerUp review, they showed the pictures of the CapXon caps:

Same with JG:
http://www.jonnyguru.com/modules/NDReviews/images/AX860i/AX860i-050.jpg

I'll wait five minutes for you to figure out what's wrong here. HINT: Both reviews mentioned the caps used.


















Still haven't figured it out? The samples aren't using the same caps. The JG review specifically said that the AX860i were using FPCAP solid polymer capacitors. That is proven by the picture they posted. But TechPowerUp wasn't wrong when they said that the AX860i was using CapXon caps.

So how can TechPowerUp and JG both be right? This is where doing your research pays off: It appears that it's a common PSU industry practice to have an approved list of alternative parts/item when the main approved item isn't available. As such, the PSU that JG got was part of a batch where only the FPCAP caps were available and the PSU that TPU got was part of a batch where only the CapXon caps were used.

As such, you cannot blame JG for not pointing out that CapXon caps were in the AX860i when their sample had NONE in the first place!

While you are correct that you should try to read multiple reviews, it also pays to actually PAY ATTENTION to the reviews rather than skim them.

Of course i read the entire reviews on all sites, but i haven't been paying attention to the images. Why? Because i would have never imagined that the same PSU could be constructed with different components inside !!!
So what's the point to read PSU reviews then? I mean if my PSU has different caps inside from the ones i read in the review, how can i ever be certain of their quality ?
EDIT: Very useful the link you attached, i hadn't noticed it so far! But what exactly does it mean? That i can mail let's say : Seasonic and tell them i want them to make me a PSU that has full of Matsushita caps for example? Is that feasible?

Of course i read the entire reviews on all sites,

Then you didn't read it carefully then. Right on page 5 of the JG review, Tazz wrote:

Directly behind it we have the LLC main transformer, and the LLC synchronous rectification board. Here we can see several FPCAP solid polymer capacitors being used.

So if you had actually read the review like you said, you would have noticed the discrepancies right away.

Read more reviews and actually pay attention to those reviews. If 2-3 different and other proper PSU review sites show the exact same caps, then you will more than likely get the same caps as them.

It basically means that you should be reading reviews more carefully in the future.

That i can mail let's say : Seasonic and tell them i want them to make me a PSU that has full of Matsushita caps for example? Is that feasible?

No, not unless you're willing to provide hundreds of thousands of dollars for the research, development, and testing for that PSU and be willing to buy several thousands of said PSUs as well.

Hmm, i think you have confused some things about myself
-First of all, if you consider, that untill recently i was bying PSUs based only by the companie's advertisement, you can conclude that i'm not a psu expert in order to understand some details that you probably think as obvious: For example, i might have read the sentence " Here we can see several FPCAP solid polymer capacitors being used.", but i thought that the PSU also uses CapXon polymer capacitors and they deliberately choosed not to mention this!
As i said in previous post i could never imagine that the same model of PSU might have different components inside !!! so i thought that JG deliberately decided not to mention the lesser quallity caps.
-Secondly, as i told you before, i'm not American, i'm from Greece, so you can understand that i sometimes have some difficulties to understand some specialized terms that are being used in the PSU reviews. We are talking about a highly specialized area that few months ago i wasn't aware of it.
-And lastly, if the PSU manufacturers can construct same PSUs with different caps, who can guarantee me that the same caps that are using in the test samples they send at [H], JG, or in the first "wave" of their production, will also be used if i buy a PSU after a while?
I think, sadly,the answer is no one !!
