Corsair RM650x or Seasonic Focus Plus Gold 750W

[Niels G]

Hi,

I am considering either one of the two, but I can't choose. Does anyone have any advice which one I should choose, and why?

 

Edit:

They both have the same price

[TrigrH]

The seasonic is newer, smaller, and of higher quality. Go for the 650w version if thats all you need.

[genexis_x]

Full specs of your PC? Focus Plus Gold is slightly better but RMx is slightly quieter. Both are excellent units, personally I'll go for the cheaper one.

[kameshss]

Both are good units. Get whichever is cheaper.

[Niels G]

@TrigrH The 750 watt version is cheaper , thanks for the advice!

Get the cheaper of the two, but your system only will ever draw maybe 400W.

Is it?

 

Like to know where you get your information from.

"One, two, three, four, five. Five cold looking joints on the line input side of the mainboard. Two more questionable, but probably solid. That'll lose you a point later, Seasonic. The rest of the board is flawless."

 

Unfortunately, I've seen a lot of failures including cold solder joints.

Which one would you suggest? I am tempting towards the Seasonic but I can't judge whether transistors in the lines is a good or bad thing

just get the corsair one

Explaining why would help the OP...

Transistors?

 

I think you mean capacitors.

 

Capacitors in the cables just makes the PSU review better because PSU's have gotten to the point of mythic ripple suppression performance and the only way to get better is to put the caps in the cables.

 

As others said:  Get whatever is cheaper of the two.  My comment was just for TrigrH that made the claim that the Seasonic was better build quality without any kind of supporting evidence.  

 

Cold solder joints is a legit issue, but that's what warranties are for.  The percentage of failed units is still fairly low.

Great!

Both are the same price, so I can't take that into consideration

By reading this I am getting the idea that I should avoid it due to poor soldering. Even though there is a warranty, I would not like to risk my components. Will I be better off buying a RM650x or does it have the same problem?

I'd just go for the SeaSonic.

You can read the reviews for yourself.  I'm not aware of any cold solder issues with the RMx.

 

The fact that the Focus is 100W more for the same money is inticing, though. 

 

Here's a question :  Why only those two options?

Well, I started on a rather big list based on reviews and tests that I saw on national sites (Netherlands) and other sites like Amazon, forums, etc. After some browsing, I found out that I could scratch some off my list.

 

Original list:

Corsair HX750i (too expensive (€60 more than RM650x)
Corsair HX850i (too much watt)
Corsair RM650x 
Corsair RM850x (too much watt)
EVGA SuperNOVA G2 650 (not the most ideal PSU)
EVGA SuperNOVA G2 850 (too much watt)
EVGA SuperNOVA G3 750 (braided cables, would be hard for cable management and 2 HDD's / 2 SSD's)
Seasonic Focus Plus Gold 750
Seasonic Focus Plus Platinum 650 / 750 / 850 (too expensive for my needs)

 

After some concluding, I got the Seasonic Focus Plus Gold 750W and the RM650x, though after your question I'm doubting about the G3 (~€25 more expensive)

Why not a 550W PSU? That's enough for any single GPU system.

You seem to have pretty good English proficiency.  Don't limit yourself to Netherland review sites.  Tweakers.net is the only competent PSU review I can think of in that region.

 

BitFenix also have some good options (like the Whisper).  Also, you seem to be stuck on fully modular.  That's correct?

 

Same question as seon123:  What 650W+.  Single 1080 doesn't need more than a 550W.

Every other review of the product on the site, only the 750w model had that issue, which is likely down to a bad batch. Which if its going to fail should be WELL within its 10 year warranty. No OEM as far as i'm concerned has a perfect production line, even amongst the best PSUs there always will be some failure rate no? (due to reasons like this)

You are absolutely correct.

 

But cold solder joints is a known issue with the latest Seasonic PSUs.  One that they are addressing, but I'm not sure a "fix" has been implemented.  Due to the fact that Seasonic's PCBA is outsourced, they have very little control over quality, process, etc.

 

Most OEMs do their own PCBA, but Seasonic is a bit too small for that.

Yes, because Seasonic.

They are awesome because Seasonic.

And everything they do is awesome.

 

Anyway, @NielsG

Since you are in Europe:
Be quiet Straight Power 11, 450 or 550W

Bitfenix Whisper M 450 or 550W, Formula.

Why go for 650W, 750W and 850W at all when all you need is a good quality 450, maybe 550W unit for that unit?

 

And there are other options available in the Netherlands as well...

I indeed would like it to be fully modular. I will try and a look at the BitFenix! I would like some overhead and also the possibility to upgrade safely in the near future.

You can upgrade safely with a 550W. Well, except for dual GPU cards and an overclocked, liquid cooled RX Vega 64 (that thing draws 450W by itself according to PCPer). 

A system with a 1080 Ti and an overclocked 7820X will draw under 400W from the wall. 550W is plenty. 

The better Be Quiet PSUs have good fans, you won't hear them under a light/no load.

There is no advantage of a semi fanless operation, if you have a good quality fan that is rather quiet in operation.

And also you have electronics noise anyway, so there isn't really any advantage.

 

And a fan spinning at around 200rpm or so is hardly noticable at all, even with Ear next to PSU...

I've had experience with power supplies that did not have enough wattage so I'd rather take some overhead in case of any problems.

I've had both active and semi-passive cooling, but I prefer the semi-passive cooling due to the less wear of the fan and the more silent operation.
