be quiet! System Power 10 750W

[Ferrum Master]

That's just it. It's my opinion that this PSU was never meant to be 750W.

Yeah but but ripple goes through the roof even at low loads, well like in 2000ies. Can you remind me when was the last we have seen passive on the secondaries? But even then it should not have such ripple levels as you could get them normal. I thought of bad/wrong main trans maybe?

Maybe it just is what it is. I'm way too optimistic.

I blame that on the poor selection of switchers. You can tell that they knew they were getting high ripple during the design stage because they use 20 electrolytic caps and 3 solids on the secondary side for filtering. To put that into perspective, the Corsair CV750, which is a similar, but not the same, HEC platform only uses 15 electrolytic caps and 1 solid on the secondary.

I like brands that I can trust. Across the full product spectrum. Not brands that have a "jeans" subbrand where product and quality is untrustworthy and circumspect.

BeQuiet is ready to risk reputation for the sake of some easy money on a cheaper lower quality product.

There is clearly a new "max the profit margin" management team, which is not the same team that built the company 20 years ago, who believed in "quality builds trust, brand reputation and loyalty".

11 A per pin. Which would be 132 W for 12 V and 55 W for 5 V.

SATA Power is 1.5 A per pin. 3 pins for 12 V makes it indeed 54 W. 22 W for 5 V and 14.85 W for 3.3 V.

132W is the maximum rated power for a single pin in the molex connector yes, but the connector itself has a total power limit of 154W, or maybe it's 156W....

Either way, all those numbers are irrelevant; 18 AWG wire to multiple connectors in a daisy chain is your limiting factor.

Nah.. They're all the same folks at beQuiet still.

Yep. This product isn't completely awful or dangerous, it's just poor. For a company like Gigabyte or Thermaltake who already have plenty of bad products to their name, that's less of an issue, but for BeQuiet it's one of their very first low-quality products, and it cheapens the entire company and everything they do. Previously you could blindly buy a BeQuiet product and be confident that it was well-designed and built up to a standard. Now, they've shown they're capable of building down to a price, quality be damned.

 

[lemonadesoda]

The secret of our success is not just the uncompromisingly high quality demand and the usage of established as well as newest technology but also the urge for constant advancement: We never accept the status quo, our products are never “good enough”. Quite the opposite: even the best ones can always be better! All of our components are being developed by our expert teams and continuously held to the highest standards. We are not interested in quick-and-dirty success, but in a solid and healthy growth. Each and every one of our products is made with passion, designed for highest reliability and durability.

Mission statement = they need to nix this bad product. Unless they want to rewrite those last two sentences.

Terrible idea:

Molex is a higher-power connector than SATA. If you convert from a lower-power connector that is only rated for 54W to a molex connector which is rated for 156W, you have high potential for it to be misused and melt/fire. That's probably less of an issue in practice because the 16AWG cable optimistically used for molex is only rated for 9A, which is 108W on the 12V circuit, but you're still looking at converting from a 54W connector up to a 108W connector. On the downside, Some SATA cables only use 18AWG and they could easily ignite or melt their wire insulation if asked to deliver the sort of power that a molex connector is capable of delivering.

In many PCs it won't be a problem, but you only have to see the idiocy people are capable of to know that it's a fire waiting to happen and with enough of those you get brand-destroying reputation or class-action lawsuits against you. As someone who manufactured their own cables for mining rigs and did plenty of research to check what was safe, I saw plenty of forum post examples and anecdotes of people using SATA-to-molex and starting fires. Within the mining community, SATA is a "do not use" cable for good reason.

Fair, with modular PSU's at least having them on one cable helps out - few modern PC's even need them.

I've got one device - just one (helix UV res) that uses molex, nothing else.

I also hate the molex connector. Enough that I'll probably solder my own Minifit Jr. onto whatever piece of crap came with a molex. That's what I did for my D5 pump....

Nah.. They're all the same folks at beQuiet still.

Completely off-topic (sorry) but since you are likely to read this thread, do you have any idea what Corsair PSU supply is so bad in the UK at the moment? I buy from (and for) Europe a fair bit and stocks seem low there too.

I'm guessing it's because of COVID production delays over in China again but Corsair seems to have worse supply than other brands. Perhaps that's just because Corsair PSUs are more popular than other brands so the inventory was depleted quicker. Any insight is appreciated, I'm buying 50 PSUs a quarter and like to stick to Corsair because of the reasonably good modular cable inter-compatibility between models...

 

[Ferrum Master]

That's what I did for my D5 pump....

I redid mine to XT30. Highly suggest.

Wait what? XT30 isn't something any ATX PSUs come with...

Just cut and solder new wires. You have spare modulars. There are no problems making your own.

Uh, WTF?! That's much worse, not better.

Molex is occasionally a compatibility problem, and necessitates plugging in and cable-managing a whole modular cable chain just for that one almost-obsolete thing you have.

Rather than solving both problems at once by replacing the molex connector with the standard MiniFit Jr connector that is common to all ATX PSUs, you're recommending that you ruin the molex device by replacing the connector with something not used in PCs, and then 'solving' that mistake by bastardising a modular cable with the other half? Why? Why would you want to add an incompatible connector to both your PSU and your (previously) molex device, permanently forcing you to use only that PSU with that device?! As far as I can tell you're reducing compatibility, adding needless work, and having to source a pair of connectors that are alien to the PC industry for no explicable reason.

Maybe I'm missing something; Can you ELI5?

Edit,
And in the unlikely case you're not aware, all of this is MiniFit Jr and in many PCs now it's the ONLY connector you will use.

 

[Ferrum Master]

Uh, WTF?! That's much worse, not better.

You completely misunderstood. You were changing the MOLEX on your D5. Not sure where you got your ideas. You construct what you use. There is no point making it compatible, what's your frustration? Actually the whole point is make it incompatible to use for only one intended use.

I am not sure I got your ideas. Your arguments don't even cover the variations of the same plug for different makers, basically the MiniFit Jr plug is irrelevant, they are not color coded and you can even manage to fry your device if you mix the cables from different sets if you have many devices, while they look almost the same. This practice should die. Making your own custom cables is a normal custom.

XT30 is obsolete only in your mind, but it is the widest used connector in RC drone even automotive industry and not only that for high DC currents while being compact and secure.

I changed the molex on my D5 to a completely standard PCIe 6-pin connector, obviously. That D5 now works fine on any ATX PSU with a spare 6-pin PCIe power plug and is 100% compatible because it's a freakin' standard.

I feel like there there's some language barrier here because you're not making any sense at all:

There is no point making it compatible

Actually the whole point is make it incompatible to use for only one intended use.

WTAF, man?!

Your arguments don't even cover the variations of the same plug for different makers, basically the MiniFit Jr plug is irrelevant

No, it's the ONLY 100% relevant plug in a modern PC; Even SATA drives are being phased out and the Nvidia HPWR connector is having enough issues that it probably won't make it into next-gen.

they are not color coded and you can even manage to fry your device if you mix the cables from different sets

They're not color-coded for anything else in a PC because they're keyed. You cannot plug an 8-pin EPS connector into a graphics card, and you cannot plug a 6+2 or 8-pin PCIe connector into a motherboard's EPS header. If you're implying that you mod the D5 directly for a modular backplane of one specific modular PSU then no, that is a dumb thing to do unless you want to intentionally lock your D5 to a specific PSU for some reason (I can't think of a good one).

why? I would say bq's history of PSU is more of mediocre to very good and most brands have a wide spectrum of lines they sell at different price points. It's a mediocre product, not their first, certainly won't be their last.

 

[Parn]

Such a shame for BQ to release a PSU of this low quality. BQ System Power 9 has been my recommendation for budget office PC build for years. Looks like I'll have to switch to something a notch higher like the Pure Power or Seasonic G12 Gold.

What I think they were trying get at is no matter what's on the other end of the cable you can't trust that is how it comes out of the PSU Corsair themselves say not to mix cables from different models even within the same SKU as the pin out could be different which is a stupid thing to do a PCIe 6+2 should be the same pinout from end to end no matter the maker or model but quite often they're not

No matter the PSU brand or type, you can always trust that the end of a cable from the PSU that plugs into your device will be standard. That is the ATX standard.

I now only buy Corsair PSUs because they are the one company that has standardised their modular cables, to some extent. We currently have Type4 cable sets and they are backwards-compatible with 10-year-old Corsair Type3 PSUs. The only caveat is that you can't use old Type3 cables on new Type4 PSUs, but at least it's VERY clearly marked on those modular PSUs as "For Corsair Type4 cables only".

Corsair production/supply is fine. If you can't get product, blame your local suppliers.

Good to hear, and yes - I already have!

 

[Athlonite]

and that's not how it should be pinouts should be the same at either end otherwise they're just forcing you into buying newer cables instead of being able to easily upcycle older cables from a dead PSU that uses type 3 this type of BS is just as bad as dells proprietary garbage mobos / cases that can't be reused

You can use type 3 cables on a type 4 PSU. Just not the 24-pin.

You probably should do a little of your own research before you post. Why modular side connectors are different has been posted to death.

As for why the Type 4 24-pin is different than Type 3's: A +12V sense, +5V sense and ground sense were added, so more pins were needed. How would you propose adding three pins without changing the connector?

 

[Chrispy_]

You can use type 3 cables on a type 4 PSU. Just not the 24-pin.

Yeah. If you personally had any influence (I suspect you may have) in directing Corsair towards a standard that's as backwards-compatible as physically possible then you have my thanks.

Not only is the modular cable compatibility good, I find the website info Corsair publish on the matter to be unambiguous, useful, and easy to find:
