[HELP] Correct 4 pin adapter for CPU

[PLAfiller]

Suup weekend warriors?

I need quick help as my search didn't convince me what to do. A friend of mine has bought this PSU: Seasonic G12 GS 750W. According to the specs (we haven't opened the box yet) it has one 8 pin cable, but his MB is Asus TUF B760 DDR5 WIFI and it requires 8 pin + 4 pin for the CPU. What is the correct adapter we need to buy? Is it Molex to 4 pin? is it 8 pin to 8 + 4 pin ? Where should we get the extra power from? Please post an image or a link if possible. CPU is i5- 13400.

Thank you in advance.

They say only 8 pin will do, so it should be fine for that i5 as well.

A quick google:

An 8-pin connector can deliver up to 384 watts of power, which is twice as much as a 4-pin connector.
This means that an 8-pin connector can support more powerful CPUs, and provide more stability and performance.

(My motherboard has 2x8 pin for the CPU, I'm using them both , just because I had the cables/connectors for it)

Yeah I saw that, but there were people arguing their CPU misbehaves at only 8 pin, so better be safe than sorry. I need to at least know which is the correct place to get an adapter for? Is it from the PCIe? Is it from molex? If it doesn't matter molex to 4 pin are the easiest to find.

Not sure where you heard that. I've been overclocking my 13900KS with just the one 8 pin no worries.

More than 8 pins in for the more serious hardcore overclockers.

Your 13400 will be fine.

OK, thanks. It was Reddit, somewhere in the comment section. But two opinions in a row in TPU saying the same thing I trust you guys more than a random post there. We will run the 8-pin only.

Don't insult us by wasting our time posting unsourced statements, post the actual link to where you allegedly read this.

I'm willing to bet however that those people either have no idea what they're talking about, or were talking about high-end overclocking, as @Outback Bronze mentioned. The former is irrelevant and the latter is irrelevant for a 13400.

YOU. DO. NOT. NEED. MORE. THAN. A. SINGLE. 8-PIN. POWER. CONNECTOR. FOR. A. 13400.

OK, mental note taken for next time I refer to something. Got back to my browser history, but I went through so many reviews, that I couldn't really find the post that bothered me. My search string wasn't really "do I need 8 + 4 pin", but "4 pin CPU adapter" which is different and returned these:

1.) an Y-splitter of the PSU's own 8 pin

2.) molex to 4-pin



3.) dual molex to 8-pin
4.) PCIe female to 8 pin male CPU connector

PSU has different rail voltages on each one, hence my question which is the correct spot to get the extra power from. Anyhow, rest assured I appreciate the time you spent to reply.

You don't need it.

Don't waste your time with those adapters. Either run it with the single 8-pin, or if you want to go overboard then get a new PSU.

 

[Remeca]

I also run my 11600k with just the 8 pin.

What's a weekend?

Beyond that, adapters, if truly needed, are potential sources of failures. Also, anything that adds additional, unnecessary connections in a circuit increases unwanted resistance in that circuit.

Adapters are fine for occasional, short term use, or as a "temporary" short-term solution until a permanent solution can be obtained.

Therefore, I agree with the others. "IF" you need an additional connector (and it sounds like you don't), buy a new power supply that already provides it.

Multiple CPU power connectors is nothing more than a marketing ploy to make a motherboard look better on paper.

The TUF is a pretty cheap, basic motherboard with arguably enough VRM cooling to warrant casual overclocking on air cooling or with an AIO, but it's definitely not anywhere remotely near the list of boards that serious overclockers would use hard enough to justify multiple CPU connectors.

The 24-pin ATX connector delivers 144W to the board on 12 rails alone, up to 75W of which can be diverted to PCIe lanes.

Typically, a motherboard with a single 8-pin connector is within spec for any CPU demanding up to 450W, and in practice that's closer to 500W because very few graphics cards pull more than about 30W from the slot these days; the exception being low-end GPUs that are powered entirely by the slot with no additional power connectors.

Honestly, it's hard to imagine a situation outside of hardcore liquid nitrogen overclocking where 500W can flow to the CPU without it becoming hot slag, so a single 8-pin is plenty. At least ASUS have you covered because you can get that to almost 700W with the addition of another 4-pin connector!

Amazing! /s

Seriously, if it's not just a stupid marketing stunt, it might be to alleviate customer support from all the questions of people working out how to connect their ancient, ATX 2.0 power supply into this board with its single 4-pin CPU connector.

#6 is right. Reddit is a cesspool of ignorants, even more when it comes to the mainstream computer sections, it's only "popular" because it's often the first result in search engines, but the content is mediocre at best.

No need for any adapters on that mobo, it's said it's 'required' for overclocking configurations but it's not like you'll be overclocking a lot with a midrange board anyway... it's all for the looks with gaming mobos. Mine needs 3x8 connectors in case you add a top of the line CPU, and the mobo was shipped with the adapter for the third connector already (they know most PSUs only come with two), which is required if you make use of all the expansion slots.

We needn't turn this into a "reddit suks" discussion especially when a link to reddit wasn't even established.

But yes, you'll be fine with one 8pin.

[ir_cow]

I've pulled 380 watts from a single 8-pin during VRM testing. It gets warm . Really though, its rare to ever actually need the second one.

Motherboards with a 8+4 is lazy and don't want to commit to a second 8pin, but don't want to seem like the MB is "underpowered" in marketing.

Honestly, Reddit it both amazing and awful. The communities in some niche subreddits are some of the most tolerant, educated, and helpful people I've seen posting on the internet, period. If you have questions about editing your own BIOS, modifying your laptop's cTDP when the manufacturer doesn't want you to, or just talking about super-niche hardware like diagnostic equipment or tech from companies that folded and vanished two decades ago...

The more mainstream the subreddit is, the more likely the unwashed masses will come along and shit all over it with their herd mentality, lack of critical thinking, and general bias imparted by places like other mainstream subreddits, youtube comment arguments etc...

You still have the option to return the Seasonic G12 GS 750W unit since you have not opened it.

Simply return it, buy a PSU with two CPU 4/8 pin connectors.



The 4-pin connector may not be intended for the CPU.

I have seen boards with 4-pin connectors that are for the PCIe lanes, also USB type C rear AIO charging ports,..

My main point was not so much about reddit but more that we probably should avoid rating other communities in general with lack of literal http/https linkable evidence, but I realize I managed to communicate that rather poorly. My brain is mush from a recent covid bout so I'm gonna blame that.

I don't need any excuses for my brain to be mush

OP: You don't have an overclocking board or an overclocking cpu, 8 pin will be ample

 

[Toothless]

If I can pull 375w on a single 8-pin with a x5675, your chip and board will be absolutely fine.

@ IZKoce, as mentioned by other TPU'ers here, the second 4-pin EPS connector (as well as an 8-pin) is totally unnecessary, unless you're hooking up a mini nuclear powerplant for supply and cool it with liquid Helium to draw record breaking power out of your socket to OC the living shit out of that I5 to astronomical heights and make the scoreboard leaders wet themselves.

Nevertheless I've two 8-pin EPS connectors on my MB too and I have them hooked up to the PSU, not because I had to, but because I thought it would not hurt and looks better.
Regarding the purpose of this second 8-pin connector, in my case (MSI MEG X570 Unify) this connector is used to support the PCI-e slots in case I'll fill them up with super duper high end power hungry graphic cards (which I can't afford anyway) just to keep the 24-pin from melting.
Some stuff is explained in this YouTube stream:

I'm not sure if ASUS implements this the same way as MSI did with the X570 boards, but bottom line is you won't need it. If your friend thinks it looks better when connected, invest in a power supply that supports it, or the cheap way is just plug in a dummy cable (nobody will notice it unless they open the case ).

 

[LabRat 891]

4-Pin +12CPU and PCI-e 6-pin have the same number of current carrying conductors (by spec).

Adapt a 6/6+2-pin to CPU power, IMO.

I've done the same thing! If I have two EPS on my power supply and board, I'm gonna use the damn things.

just don't mix up the pin layout or you'll have bad day (hardware wise)
