12vhp cable Adapter plugging question ?

[CasoF13]

is it ok to use a 4plug pci 12vhp adapter with only 3 dedicated cabels from the psu or a 3 plug adapter with only 2 psu cabels similar to this example ?

 

 

thx in advance

also can it damage a gpu if i use a 4plug aftermarket adapter on a gpu that shipped with a 3 plug adapter only?

If you have a quality PSU then  it shouldn't be a problem.  However, Daisychaining on low quality PSU's is not recommended.  People don't even recommend daisy-chaining at all but I have done so with my 980ti, 2080 super and I am doing it with my RTX 4080.. I have overclocked the cards to the max without any issues.  I am running a Corsair RM750i.

I think it would warrant mentioning what PSU you're talking about.

 

Newer PSUs that use a daisy chained set of 2x8pins can generally support 300W properly. 2 cables with 4x8pin in that setup is sufficient for a 600W 12VHPWR.

 

If its an older PSU but still has 2x8pin daisy chained cables, I'd say you'd be safer running 3 cables with one daisy chained.

 

The other stuff you've mentioned, I'd stay away from like the plague. I've got quite a varied experience with 12VHPWR running weird configurations and its a scary connector, but as long as you seat it properly and don't do dumb stuff like extensions and PSUs that don't support the wattage draw, you should be fine.

i am not planning any oc at all. i even want to undervolt it for a better efficency

the question is if a 750 psu on a 4080 or a 850 on a 4090 (i am still planning)

but i want to reduce the extra cabling so thats why i am asking if one of the psu cabels is ok to be split at the adapter end (only one the other cabels are 1 cable to 1 adapter plug)

Personally I'd stay away from aftermarket adapters, I deliberately spent more to get the one sold by my PSU manufacturer.

 

I do have one GPU using the supplied adapter as I haven't gotten around to replacing it but its cable tied above the GPU (ugly but functional) so that the weight isn't straining on the GPU connector.  The case is hidden behind the monitor so not concerned about "the looks" but I will likely still replace it with the official cable at some point.

I have a 4070 Ti (previously a 3080) running off a RM650x and had a 4090 running on a RM850x perfectly fine.

Its largely down to the quality of the PSU as the 3080 didn't work reliably on a Cooler Master 650W Mastercool.

i want to use a linkup aftermarket adapter similat to the pic are these good? my fear is - a hardware local reseller is selling also returned hardware for a discount the thing is the dedcription said that not all Accessoires are shipped with it so i probaly need a aftermarket adapter

Why not just get a native 12VHPWR power supply then if you're potentially buying a new one? Otherwise the first party adapters from Corsair and Seasonic for their power supplies are just as good. Native ATX 3.0 / PCIe 5.0 power supplies aren't that expensive, especially in the 850W category.

 

850W will be plenty for a 4080 or 4090, but if you're running a high end CPU and overclocking the 4090, 1000W/1200W is recommended.

because my 850w psu from fractal is already good and the cable od it are super flexible unlike corsairs (for me at least)

MSI - MPG A850G PCIE 5.0, 80 GOLD Full Modular Gaming PSU, 12VHPWR Cable, 4080 4070 ATX 3.0 Compatible, 850W Power Supply - Newegg.com

 

Best value 12VHPWR native 850W in my opinion.

 

Seasonic VERTEX GX-850, 850W 80+ Gold, ATX 3.0 / PCIe 5.0 Compliant Full Modular, Fan Control in Fanless, Silent, and Cooling Mode, for Gaming and High-Performance Systems, 12851GXAFS - Newegg.com

 

Probably the best 12VHPWR native PSU line currently available. I went through a few different solutions before going with the 1200W version for my system. Has individually sleeved quality black cables with a long 12VHPWR cable, which isn't the case for all of the 12VHPWR native PSUs.

 

be quiet! PURE POWER 12 M 850W 80+ Gold, ATX 3.0 compliant, PCIe 5.0 compatible - Newegg.com

 

Probably the cheapest one I'd trust with an expensive GPU.

An 850W is perfectly fine, even if you need to only use 2 cables daisy chained. Just be weary trying heavy overclocks like what I run since that will regularly draw +550W alone. I started with my RM1000x and two daisy chained cables, added a 3rd just to be safe like 3 weeks into the same overclock.

thx i planned to undervolt anyway an no ocing so power draw will be less but thanks for your and all the other helpfull souls help but now its bedtime thx again

Undervolting is more trouble than its worth IMO, other than the OC Overclocker tuning in there.  Its already a very power efficient architecture where the voltage and performance sweet spot is at like 80% power limit.
