I never said it was. :banghead: Read the review I linked.
lmao, relax your badself. The OP is doing a fine job trying to blow it all up w/o the psu's help.

Something doesn't sound right. It's unheard of for a power supply to not have any 6+2 connectors, since 6-pin power connectors are so common.

If you make sure to be specific about which PSU you're talking about (since you've got at least three on hand) it would be less confusing on our end.

Most of the connectors will be 8-pin on one end where they plug into the power supply, but the should still be at least two 6+2 power connectors amongst all those modular cables.

EDIT: Never mind, I read your post above and it clarifies things better.
Hi,
Really seeing most psu's I have came with 6-vga cables enough for 3 gpu's lol
Also all of them came with 2-4x2 for cpu to fill at least 2x8 pin boards

Anyway, think we found the problem. Tomorrow I'll see if I can get hold of an extra 6+2 pin connecter for the GFX, and I will update you, when I've refitted the cables. Thanks for the help.

Where is this "extra" 6+2 PCIe power lead coming from?

You generally can't just "find" a cable from some other PSU and hope it'll work. There are a dozen different OEMs that make PSUs and they don't use the same pinouts on the PSU side. Which is why you'll see a custom cable maker like Cablemod maintain different kits for different PSUs; even if the number of pins are the same, the pinout is not.

It should be clearly visible which one is a 6+2 and which one is a 4+4 EPS. The locking tab on the EPS splits into two, symmetrically. The 6+2's locking tab is located squarely on the 6-pin piece.

I'm just trying to explain that this PSU isn't worth keeping even temporary. I'm sorry but you didn't read before replying, not much I can do about that. I think you can handle a simple emoji. ;)

Yeah TPU already confirmed its excellent quality. /s

I did check what's in stock in DK, it's a lot worse than I imagined.

So I guess you've got all the cables you need then. I'm pretty sure those dual outputs are supposed to be used at the same time.

But again, that PSU is crap. I still think you should RMA it while you can, not only to save money, but also to avoid damaging any components. (unless it's too late)

According to "Linus Tech Tips" one cable can draw a max of 150 watt - which is why there is 3 inputs, since the graphics card can pull a little above 300 watt. However, an extra output on one cable, doesn't make it able to actually transfer 300 watt, so using 2 outputs from one cable should, again according to "Linus Tech Tips", be concidered a nogo.
But maybe you're right, I could just do it, since it's at the very max it draws above 300 watt, and I won't be benchmarking it, before I get my 5900x and Be Quiet 1000 watt psu anyways, so it won't be needing enough power to become a problem.
Besides that, the best way to overclock a 6900 xt, should, according to "der8auer", be undervolting them. If that actually makes them draw less watt, well, then it's a win/win situation.

You really need to STOP building computers.
Thanks alot for your general constructive and very helpfull comments. However, we got the situation under control here, so you can use your time elsewhere.

Hi,
Well I have to give corsair a little credit at least they only pigtailed the +2 off the 6 pin vga cable side lol

Not sure if you're aware, but power supplies are one of the most thoroughly tested components in the manufacturing process. If there was a flaw where it couldn't be plugged in properly, they would have rejected it on the production line.
Ummm, no. Sorry but just not true at all!

It would be great if each and every PSU coming off the line is tested, but no way is that happening. The logistics and resources involved would be way too expensive and time consuming to pull each PSU off, inspect each connector, power up the PSU and test all voltages. No way are they doing that.

They likely test 1 or 2 units out of each production run and that's it.

Also, like many PSUs today, including the OP's PSU, it is modular PSU. No way are those modular cables coming off the same production line as the PSUs. It would not surprise me if the cables are made in a totally different factory. And only later, during packaging do the PSU and cables (and mounting screws, documentation) come together and stuffed in the box.

So no. Just a tiny percentage of PSUs are tested - and I doubt even thoroughly before they leave the factory.

I'm not sure that's true. Many brands do the same. It's 150 W per 8p connector AFAIK.

I were going to contact the shop where I bought the PSU, and buy an extra cable.

However, with second thoughts, I really don't think it's needed, and I can just go daisy chain one of those 2 cables I got with 2 connecters on it.
I "just" need to find out, how the graphics card, is drawing its power. If it uses first one port for 0-150 watt, and then another, and the last port from whats above 300, I need the daisy chain, to be on the last of those 3 ports. So I don't end up having the graphics card, try to draw 300 watt through one cable.

Or if it's splitting the power it draws between all 3 connecters. In that case, it might be a problem using 2 connectors from same cable.

I personally want separate cables for each connector but that's just me. At the moment you don't even have to start a game, finding out that it boots at all is good enough for now.

According to this page:
You're right about the 8 pins, it's the connecters that sets the limits, not the cables.

No, it's definitely true. Have a look at these images of power supply production and you tell me what they're doing:

1613946774999.png


1613946828858.png


1613946800831.png

These are production units. Not R&D, not random sampling....every single PRODUCTION unit goes through plug-in testing at each stage of manufacturing. It's part of the quality control process and has to be done to prevent costly RMAs.

Look at what Coolermaster does, they run burn-in tests for every production unit to ensure they can withstand worst-case loads (go to 9:40):

Thanks for that and yes, I am surprised that much testing is done. I was certainly wrong by saying 1 or 2 per production run.

But I do note that video is certainly used for marketing purposes too. Also if you listened to that video, it said the cables are made elsewhere and packaged together later. So the cables that come with the PSUs are not tested with the PSU. And my reply above came about due to the comment that testing at the factory would have found a bad cable.

Sure, no that's a good point. I know that power supply manufacturers don't really like fully modular power supplies for the reason that having a removable 12-pin ATX connector introduces additional points of failure that can't be fully eliminated by testing. But semi-modular power supplies just aren't very popular with consumers and so there's no choice but to go fully modular.

I believe the PSU manufacturers still do random sampling (I think it's covered in the GN video) but it's so rare that any quality issues are found due to all the prior testing. Power supply manufacturing is much slower and thorough than one would think.

I rewired the setup, but nothing changed, the same sound is comming from the PSU, when I try to turn the machine on.

I'll just deliver it to some IT service tomorrow, else it won't be finished until a month from now. Damn, assembling it was a nightmare! It's a little funny, how there can be so little space, in this super huge be quiet case.

Thanks for all the helpfull comments. :)

Hi,
3600c14 is new stuff mostly for z490 that I've read so yeah likely not amd compatible it takes a lot of dimm voltage 1.45v I believe to achieve c14 pretty funny if you think about it lol
3600c16 is good for amd and only needs 1.35v dimm voltage so yeah is c14 really worth turning sticks into space heaters :confused:

Gigabyte well just look at the last part of the name should give you a clue what's to come byte/ bites I personally wouldn't buy anything of theirs sure not some new psu.
OP is having problems on first boot, therefore he's running RAM at stock settings, not XMP. It's impossible for the RAM CL / frequency to be the issue here. He needs to first be able to boot into BIOS in order to enable XMP profiles.

Second, even if we assume he did enable XMP, your advice isn't sound. You can run DDR4 3600cl14 at 1.35v just fine on AMD (which is stock for G.Skill trident Z 3600 kits). I've done it with my 3700X and it's an early production unit. Now DDR4 3733 is a problem on AMD due to the limitations of some chips not being able to reach a 1:1 infinity fabric divider at that frequency. If you need to, you can use the AMD DRAM calculator to tune timings to suit an AMD CPU.
PSU: Gigabyte P850GM

That power supply has some extremely bad reviews from both users and professional reviewers. I would first ask the shop you are taking it to try and substitute another unit in and see if that fixes the issue. In any case I would want to replace it regardless. Your build is too expensive to risk to a low quality power supply.

It's the one I got in my old computer, bought in 2013.

Kind of old but I did manage to find a review of it: http://translate.google.com/transla....overclockers.ua/power/huntkey-800w-xfx-850w/

It doesn't appear to have any critical flaws like the Gigabyte but testing was less rigorous and we have less info to go on. At the very least I'd say it's worth installing and trying. Not sure about long term use though.

It's not long term, I expect the PSU I ordered should arrive in 1-2 weeks from now.
You might have missed it, since you joined the debate late, I have a be quiet! Straight Power 11 Platinum 1000W in order, the GIgabyte (Or now my old XFX) is just a standin until the other arrives in the shop.

As Mats mentioned in an earlier comment, the PSU stock in Denmark, is horrible at best for the time being.

I just did a little search for it, and as they had found out in the review you linked, my XFX PSU is actually a Seasonic M12D series - https://www.realhardtechx.com/index_archivos/Page625.htm - That's a little odd, since the reason I checked, was because the review you found actually was of "XPS-850W-BES", but apparantly they're the same Seasonic PSU to begin with.
On that page I found this review:
It's 5 pages, super long, but if you're looking for something specific, you're welcome to check. Don't read the entire 5 pages!

In the conclusion, this is added under the "bad" section:
- OCP failed to power off unit in max-load test 7 before it died with a bang.
However, my build should draw around 500-550 watt, so I don't see that as a huge problem.

Where is this "extra" 6+2 PCIe power lead coming from?

You generally can't just "find" a cable from some other PSU and hope it'll work. There are a dozen different OEMs that make PSUs and they don't use the same pinouts on the PSU side. Which is why you'll see a custom cable maker like Cablemod maintain different kits for different PSUs; even if the number of pins are the same, the pinout is not.

It should be clearly visible which one is a 6+2 and which one is a 4+4 EPS. The locking tab on the EPS splits into two, symmetrically. The 6+2's locking tab is located squarely on the 6-pin piece.

I got a set of cables from their PRO series for my Seasonic and I'm not sure if their other kits for EVGA and Corsair PSUs suffer this problem but...the majority of my cables aren't labeled, with the exception of a couple "PSU" stickers on the ends of some. But as far as the PCIE cables go, no labels on either end, dear lawd. I pretty much had to figure out which were the 8-pin mobo cables and the PCIE cables... :fear:

As far as the topic at hand is concerned, OP, DO NOT DAISY CHAIN THE GPU CONNECTORS, FOR THE LOVE OF GOD! If a card has, say, 3 8-pin (6+2) power connectors, then your PSU damn well better include THREE separate 6+2 PCIE cables!! Pigtails might work for lower-end cards that don't require a lot of power to feed and keep feeding, but doing the same thing on a high end card like the 6900XT is just ASKING for the damn thing to blow up - if you haven't fried the damn card already!

I were going to contact the shop where I bought the PSU, and buy an extra cable.

However, with second thoughts, I really don't think it's needed, and I can just go daisy chain one of those 2 cables I got with 2 connecters on it.
I "just" need to find out, how the graphics card, is drawing its power. If it uses first one port for 0-150 watt, and then another, and the last port from whats above 300, I need the daisy chain, to be on the last of those 3 ports. So I don't end up having the graphics card, try to draw 300 watt through one cable.

Or if it's splitting the power it draws between all 3 connecters. In that case, it might be a problem using 2 connectors from same cable.
Don't forget about the pcie slot. It delivers 75w to the card also.
