Don shoot me because buy prebuilt pc and old GTX1650 GPU
How to know max refresh rate supported by this desktop GTX1650?
It come with DVI D & HDMI port

144hz? i googled that for you sweat.gif
but you need to have DP and correct display.

Very soon your PC need 2nd power cord because your GPU will come with a freaking PSU.
They could made second connector to distribute the load, instead of every cable cramped into single connector delivering 600W.

Pin based connection have limits, i used to be working on machine for japanese, they insisted using screw based terminal because it provide better contact.

600w is not a lot wert tongue.gif  half a 1hp aircon power only, the small punny 12vhpwr can take it as they certified it. lolx, Just kidding.
*
600W is not a lot if the pins surface contact is good, good contact = lower resistant build up.

remember those molten 13A wall socket, those are cause one bad contact plus over current, the same thing will happen to GPU, EVGA really dodged a shell here lol

dont know how these stuff can make into ATX 3.0 spec lol, customer are the best and free QA/beta tester!

smartphone also pushing high speed charging, supervooc now 150W sweat.gif
but at least the stock cable and other cable i use provide very firm connection.

it looks like rush job here, welp, Christmas is near, collect money from sales first, do rework later!

Oppo demo-ed supervooc support 240w over usb-c,
phone with 150W charging support already released on the market.
earlier version with 65/90w also never heard about ppl complain burn charging port or exploding phoene.

inconsistent cable quality + design oversight. i'd say.

Nvidia can consider supervooc 240W over usb-c, 4 x 240w over usb-c will solve the issue, not to mention you ONLY need 4 cables. notworthy.gif tongue.gif
world first usb-c powered GPU. lol

Sorry guys, some correction after reading standard 6/8Pin PCIE connector spec, "most 6 pin PCIe connector with 2 x12V yellow wires"

**Rule of thumb = 14awg wire carries a maximum of 15 amps, 16awg can carry 10 amps of current where as 18awg can only carry 7 amps of current
Found something interesting, check the below 2 links from aliexpress on the 4-1 adaptor

Adaptor 1. It's written there says that
a.) Wire gauge: UL3265 14AWG + 28AWG
b.) Current rating 9.2A = x4 PCIE connected x2 yellowwires x 9.2A x 12V = 883.2W. (But if 14AWG max is 15A = x4 x15A x12V = 1440W max)

https://www.aliexpress.com/item/10050048556...763876148%21rec
Adaptor 2. The same adaptor but with different cable spec
a.) Wire model: 18AWG
b.) Not mentioned, I assume is 7A = x4 PCIE connected x x2 yellowwires x 7A x12V = 672W

https://www.aliexpress.com/item/10050048399...695947517%21rec

Looks like the regardless 14awg, 16awg, or 18awg, all met the 600W rating. However looks like 14awg is overkilled, 18awg rated just on the line, the best is stick with 16awg
Cablemod.com is selling the 12vhpwr cable 4-1 comes with 16awg which in my opinion is good.

Just sharing my opinion, I could be wrong.  notworthy.gif  icon_question.gif

the connector melt because contact not good, if user bend the connector like side way/bend downward(because never read the f*king warning), may be only 25% or less surface mate with each other, instead of 100% and possibly create arcing ,
acing will further create resistant due to oxidization between contacts, that's where molten connector come from.

wires gauge has very little to do with melting connector, last time i working in switchboard for motor controller, the cable is not thicker than those PCIE 8 pins, like half and only 5 cores (3 live, 1 N and 1 E),
i use the cable it can power up 3 phase vacuum motor lol, it run fine until shipped to STmicroelectronic China

Bro, you are right in a way. Connector contact must be tight, else causes resistance and heat when current flow through.

But I also do believe in wire thickness, I have seen before overloaded devices on a single 3pin extension cord where the cable heats up and causing burned at the 3pin plug. but changing to a thicker cable with the same connector doesn't causes any heat on the same load.
*
it must be thicker due to it's only 3 cores, live wire does the most work,
while PCIE and 12vhpwr has 8 cables, so they're adequate for their job,

thatt's why some appliance like water heater for bath room has special rounded socket, and it's 15amp.

if people are smarter and don't use cheap power stripe, and keep daisy chain them. they could avoid a lot of trouble.

burnt socket/plug is due to the contact between pins/wire has the highest electrical resistant than the rest.

They knew they fked up, instead of rectify the issue, they ship the defective product with a notice warn what you should not do..
And the connector is designed by Nvidia, welp, there gonna be class action lawsuit incoming in US.
There rest just waiting for failure to occur then RMA.

I wouldn't be surprised if EVGA go to red team

Anyway here are the meme lol

For those already have 4090 powered up,
Never leaves your pc unattended, or let the game idle,
plastic burnt smoke smells really bad, it may melt the plastic connector and wire insulation for hours, plastic smoke are generally toxic,
and the worst is up in flames.

This is the exact reason why you should never buy new and fancy tech at launch - you're essentially paying companies to do QC for them, and the usual early adopters tax icon_idea.gif

plastic to be melt at 1st then eventually the whole connector and the gpu power connector itself i guess?
what's good when the plastic not suppose to be melt in the 1st place. its like a time bomb just waiting to go off.
*
Plastic connector melt first, electrical resistant between 2 pin and receptor are the highest.
When wall socket overload, the that always melt and up in fire is the plugs/sockets too, depending on the quality, then the wire insulation will slowly melt.

That's why in industrial switchboard they prefer soldering or screws clamp.

let's make things more confusing, see what cable mod said in regards to that matter

user posted image

however, the inference from the FE manual is very strong, "Use of non-compliant or third-party power connector adapters may cause technical issues, and may void your manufacturer warranty".
wonder who's right or wrong now.
*
The adapter from first post about burnt connector have nvidia brand in it, they knew it has issue, even their own adapter also fried.
Just admit you have done fkup up nvidia.

I suggest people don't buy it, not worth the trouble and time.
Wait the product recall then wait for new 4090 with proper connection that doesn't burn down your house when you are not looking at it

i think the problem is not just the adapter, it might be issue with the socket design itself too. i notice the socket pins are very small/thin/delicate to hold such high voltage

i still playing games everyday and monitor closely on the adapter and socket

edit: i wonder is there a list of which brand burnt the most including FE
*
Nvidia designed the 12vhpwr, they can blame no one else.
If you think then pins are small, usb-c very soon will support 240w charging.

2x 12vhpwr might just alright IMHO, 1x is pushing to the limit.

I can only imagine that nvidia test their gpu in open bench, short gpu stress test then pack up ready to ship! Lol

we always use our cable from PSU. So our GPU power cable is always third party.
How can nVidia ask us not to use third party cable. So weird.
*
They are pushing the blame, just wait for class action lawsuit, or more serious incidents.

All it take is just more tech site to recommend against buying 4090 and more burnt connector.

any thermal pads to recco for this section? 2mm/3mm?
the stock ones is putty, and don't contact well with the heatsink and dried up

or i need not mess with it?

When you open up the heatsink, putty one must re-apply, especially the highlight one are vrm, which is same important as die l.

Remember the good ol VGA? analog, low voltage, older than some people here, use 2 screw to tighten.

12vhpwr, transfer 450-600 wattage, USE PLASTIC CASE AND CLIP TO SECURE.

seems like need to put more force to make sure its fully insert or hook up the psu cable properly 1st before slot it into the pcie.

i suggest people do it once and do it right,
remember the connector has max 30 mating cycles, if close to maximum, people might still end up with burnt connector.

30 mating cycle is just adapter right, not the psu 12pin

The PSU connector are bigger, and probably more durable.

but you have to take the gpu receptor into consideration too,
when a smart phone company can push usb-c charging to 240 watt, while multibillion company designed much larger connector still end up burnt.
