Really?

 

Well.. you could just RMA it and try again.  Failure rate on those is like .01%.

 

Yeah, everything I had read before making the purchase said they were super reliable. I was rather surprised and a bit worried something else had died when it happened but it certainly presented as PSU. Put the unit I had replaced back in and everything else is fine. RIP RM850x. Not worth going to those Seasonic Primes or Focus GX? I kind of hated the stock cables on the RM850x anyways; they don't work well with my case. I was ready to order some cables but since I'm back to square one anyways I would rather spend the money on a better PSU than on aftermarket cabling if I am going to spend the money either way if that is feasible.

Well, the double forward means it might not hold up to the high transient spikes of the new 30xx cards.  I haven't seen any tests with that particular PSU, but all of the other double forward PSUs I've seen do not like the new cards.

 

And the lack of DC to DC means that you don't get 98%+ of your +12V on your +12V rail.  So while it's a "750W", you're only getting the same amount of power as a good 700W.

 

It's just not a good value unless you were using a lower end graphics card.

 

Ok if i understand this correctly the double forward translates into the 2 cables with both 2x 8pin pci-e, couldn't i just plug in both forwards into the 2x 8pin's on the card to combat those spikes?

And when i look on the model page url it says 62 ampere on the 12v line, so 62x12 =744w but then cuz it's not combined i have do deduct like +/- 200w for the +3.3V and +5V  leaving me with 544w for the gpu, that wouldn't be sufficient or wise?

Those Seasonic units you mentioned perform worse than units from the RMx lineup, almost universally, and have confirmed issues with NVIDIA's new cards. I'd take @jonnyGURU's advice for now and try for an RMA.

 

Custom cabling is fairly easy to do yourself if you feel like going that route, there are plenty of places to buy them from otherwise.

Yes, the Focus and some of the Primes are shutting down withy the 3080 and 3090's.

 

Just saw another Focus mentioned today, 750W shutting down with a 3080.

Ahh... I had only seen the possible issue with some Focus and assumed it was isolated to older models (per the list and the first footnote). I hadn't seen that the Primes were also affected.

I realized that I should have started a new thread, other than maybe mentioning the RM850x RUD here, and thus I'm going to do that. Sorry for clogging up this thread.

God no.

 

Double forward has nothing to do with the cables included with the PSU.  It has to do with the topology of the PSU.  Double forward vs. LLC resonant. 

 

If you're inclined to do so, maybe read some proper PSU reviews with tear downs, component analysis, etc.

Ok, well Ive read upon some reviews bout the Double forward vs. LLC resonant stuff, from what i have learned most gold and higher rated psu's have LLC resonant topology, and i came up with this one :

Zalman Acrux ZM850-ARX

This should be sufficient,right ? it's low priced here at 120 euro, don't wanna waste money if this does the job well and the cables look like they can be bend easily to fit some tight corners.

This PSU were supposedly tripping with multi-GPU setups, i.e it's probably high-transient sensitive too, not a very good choice for RTX3080. You're from NL ? There are a lot of good PSUs for 120E budget, like Bitfenix Whisper, FD ION+, Corsair RMx.

any idea which focus it is?

PSUcultist (the people of this list) are looking into finding what units are sensetive to Amperes transiense

Is there somewhere that we can watch this conversation?

Well how is it high-transient sensitive too when it a platinum unit, isn't it then LLC resonant and not sensitive to high-transient spikes?

not really related to how transient sensetive it is.

not really any good place to watch this conversation. its really just noting down some units. either through PMs or discord etc etc.

Nope, they didn't say other than Focus 750W.

Add the Thermaltake GF1 to the list of not working with the 3080/3090..

Just personally tested the 3080 FTW3 Ultra with the Seasonic Prime Ultra Ti 750W (750TR) and it's good to go.

 

No shut downs etc.

 

Was asked to test it over on the EVGA forum....

[Ankerson]

Just got word of two Seasonic Prime Ti 750W's shutting down with the 3080....

 

The Non Ultra (750TD)

which wattage? and load conditions?

yeah Prime is very sensetive to the ampere lineup. Prime is pretty much a given unless proven otherwise. 

 

hopefully the 3070 wont be as bad. 

[Samfisher]

To anyone who knows, how would I go about testing my PSU with a 3080 if and when one is in stock?  I have a lead that might get me one by Friday next week, and really wanting to see if my CM V650 (MPY-6501-AFAAGV-UK) works with it, otherwise RM850x here I come I guess...

Superposition seems to be a load to enduce tripping.

850W and Gaming... Benchmarking...

Not all the Primes it seems, Like I posted (And you left out it was the Non Ultra 750TD) the Prime Ultra Ti does work fine... (Model 750TR).

Apparently, CM has refreshed its V series line-up (MPY-550V-AFBAG ; -650V- ; -750V- ; -850V-), labelled as "V2.52" ;

Other than removing the FDD cable, spacing out the 8-pin connector sockets and adding one for the 650W and 750W models, should we assume nothing else has changed, or do you guys have some insider info on this refresh ?

Given the V2.52 version number, I would assume these are updated to meet ATX 2.52 demands, similar to RM 2019 vs. RMx.

When LMG Staff reference this list to select components lmao 

 

"At Worst it's a teir D" 

 

They also purchase a 3800xt and used 1080ti for $400
