As far as I remember 8 pin is good for 150W and slot is 75W.

There is a reason Corsair sells 2x PSU 8-Pin to 12VHPWR cables, that's 300 watt each.

1x 8pin OR 1x 6pin for the 7600XT and below 1x 8pin/ 1x 6pin for the 7700XT and below 2x 8pin for the 7800XT and below 3x 8pin for the 7900XT and above Done. Its a none issue, Nvidia made it an issue.

Don't get me wrong I think we can happily get a new connector, but trying to fit that much power into a single cable was stupid They should of done 2x8/12pin (new ones that allowed maybe 300w of power) or something else that wasn't a single cable to make it so we didn't need 3/4 cables for cards... that would of been fine as well though its been funny to see basically no one else on board with the whole thing xD Though think the bigger issue is cards are drawing far too much power, can we go back to 250-300watt cards now please

Blame 4K, 5K and 8K for the increased powerdraw.

A PSU maker can do that, because they know the capabilities of their PSU and their cables. A GPU maker can not make such assumptions, because the official requirements on those cables/connectors is only 150W each.

The cable is not the problem. Its entirely the connector/adapter combination. And 6+2 pin connectors have also melted in the past when they were installed with too much bent or through other factors. It'll likely turn into a non-issue once PSUs have proper native cables with sturdy connectors, and no adapters.

well my next build will have one those AX 3.0 power supplies but it could be 6 month before i do another build it could be another 3 years before i do that, I reduce power consumption of 1070ti from 180 to 130 with undervolting thanks to @CrazY_Milojko, and i couldnt be happier, less power draw less heat and quite gpu operations. with little to not lose in performance it stays as it it is less i start geting BSOD or something

How many melted 6+2 pin? Too many, and noone cares 😀 https://imgur.com/a/D9oEoXH#MAexSpa https://imgur.com/a/D9oEoXH#MAexSpa

Yeah, who cares if you get a dodgy product... Well, when it comes to business you better care because that's your rep. Out of the TINY amount of stock they released the 4090s on I am sure there is a good 1-3% that are doing this already and the card is only a month old. That's really bad... 4090's only sold out because they only released a handful of them. Nov they will be sitting on shelves. haha

It's good because no matter if it pulls 450W like a 4090, it won't turn into fireworks. The case that went viral on Reddit is not the only one that has happened in the wild at all. 12VHPWR is really misbegotten.

Quoted for ignorance. 8pin connectors have gone up in the same way on countless occasions.

Slot is 66w, the rest are non-12v signalling and standby power.

One of my favorite tunes by the old Deep Purple with David Coverdale I'm not a huge fan of all there music but this 1 is just one of those songs that is a classic. [Sorry off topic]

Why is it good? It's still using the same number of pins and connectors, or more and enormous amounts of power.

its actually not the same number of pins, there are only 6 pairs that carry power on the 12vhpwr, where as the old 8pin connectors which are rated for 150w, have 3 pairs+ 2 additional ground pins, so ignoring the extra grounds, 2x8pin connectors for 300w has the same number of power pins as the 600w12VHPWR connector, to achieve 450w on a 4090 you would need 3x8pin, which would be 9 pairs, or 12pairs for 600w. so quite literally half the pins of the old standard for the same power, , clearly the safety margins are inferior with the new connector.

You're completely correct on the first part of your post. The design is easy to cheap out on, and having modular connectors on both sides of a cable adds to the points of fatigue and failure. These GPUs are now so power hungry I wouldn't be suprised if future units have direct power rail edge connector behind the PCIe slot, and some kind of motherboard passthrough is set up. 12ATXVO is a standard that has that configuration in scope.

PCI-SiG themselves melted the connectors at the PSU end, so this problem is far from over.

Reducing the pins from 3x8 to 16 and then trying to push more power is quite stupid... and for what, to save space on the PCB?! LIke my GPU is a portable device and space is an issue... 😀

It's not just that, the 12VHPWR connector is the size of a single 8-Pin and that can handle over 300 Watts, the number of the pins and smaller size simply do not add up to 600 Watt.

they are PSU (type 4) to 12VHPWR, they are not PCI-E to 12VHPWR adapters each PSU type 4 attachment on corsair modular PSUs are used for 2x 8-pin PCI-E, so 2*2*150 = 600W https://www.corsair.com/us/en/Categories/Products/Accessories-|-Parts/PC-Components/Power-Supplies/600W-PCIe-5-0-12VHPWR-Type-4-PSU-Power-Cable/p/CP-8920284 https://www.corsair.com/medias/sys_master/images/images/h4e/hb5/10252903055390/base-CP-8920284/Gallery/PCIe_5_12VHPWR_PSU_Cable_Type4_01/-base-CP-8920284-Gallery-PCIe-5-12VHPWR-PSU-Cable-Type4-01.png_1200Wx1200H

Who cares if its 3x8 or 1x16, +400w for a GPU is really stupid anyway.

Quite surely. Considering also that Nvidia is on N4 and from all the facts we have AMD is on N5. And in general just being behind in the whole RT scene which isn't tbh easiest to simply catch up.

If its available, doesnt burst into flames and is cheaper, id take the hit on RT.
