PCIE slots can provide something like 75W on their own, so a GPU installed but not plugged in will still run, albeit very shit. It will run enough to post to BIOS, and enough to get into settings and mess with drivers in safe mode, but you won't get any performance out of it

[@maintake3792]

Correct! My GTX1070 from zotac would post fine without the 8 PIN

[@joveaaron-real]

I was searching for this comment. This is true

[@axeldaelmans7215]

True! Also, ive seen this but dont know if this works for every GPU, but if you plug your monitor in IGPU port, the GPU would still render it but display it with the igpu, i wanted to test my UHD750 lately, but i was surprised to see 400+fps on valorant, turned out in task manager nvidia still did the hard work 😆

[@richardmillhousenixon]

@@axeldaelmans7215 The latter is only true if the card has mGPU support, which to be fair is most cards nowadays. But the old ones that required a Crossfire or SLI bridge to run more than one card won't behave like that

[@ravioli0239]

Not all cards will power up with just the pcie slot, I've had this happen a couple times when I forgot to plug the cables back in after taking the GPU out for cleaning

[@mirekstanek]

That happened to my friend. Dude was playing for 5 months on his CPU entirely until I came to visit him and noticed that his 1660 was really not doing great. And Oh man, when I had a look at the back of his PC he had HDMI in his motherboard instead of GPU. My man had a blast with his PC afterwards and He is joking about it to this day. He knows how to make fun of himself 😄 Im not a PC expert myself, but I knew this was a nono and I still have no idea why it didnt show black screen like my PC did when I did the same mistake 😏

[@RealAnslanternYT]

For me, my mistake is building a PC where the PSU to the GPU is connected via a 'converted' cable from a 6 or 8 pin to 12 pin instead of using the 12 pin to 12pin type cable directly connected to the PSU

[@skystreem4860]

Personally, I would ban anybody who’s being deliberately malicious when somebody is just trying to understand something not knowing something isn’t a crime

[@CristopherYusuke]

Depending on the setting in the BIOS, you can actually use your external GPU through your motherboard HDMI port, similar to how laptops function, essentially by passing the power from the GPU to that port. If I am not mistaken, there is a slight increase in latency, but if you lack HDMI ports, it is a very good solution.

[@CristopherYusuke]

I found the setting is IGPU multi-monitor

[@Ficles81125]

Two fun facts there is a lot of GPUs that can run on pcie power alone without separate cables and sometimes HDMI from the graphics card can pass through to the motherboard port which is used most commonly on laptops

[@Kyermike]

Doesn't the GPU state "Please plug in the cable" or something when starting it up?

[@DrEtzor]

The thing is though that the GPU will provide some of it's performance through the motherboard HDMI port (for example) but it won't be anywhere near the same as if you'd put it on the GPU port.

[@pineapplefadeaway1827]

I wish I knew this with my old pc, it was a GTX 1080 and I had no idea until yesterday, the PC is destroyed now sadly due to somehow spilling kool aid on it but I’m thinking about salvaging the Corsair h100i off it and putting on my new setup… That setup lasted me my greatest years and yknow I’ll probably never actually get rid of it as a whole!

[@loganstaats8215]

Back in my day our pcie slots powered our cards on their own... good times :(((

[@pitangura]

You can actually pass the calculations done by the gpu through the integrated graphics drivers

[@TheTrueDarkNight101]

So here's something that people may are, may not know when you don't have the 6 or 8 pin power connector plugged into the GPU, it is more likely going to have a critical error, not realizing that GPU is not drawing any power, therefore, if it is plugged into the PCIE slot it's going to be confused more or less over what's plugged into the slot because it will see that it is not all there and is going to have a critical error and is going to give shitty fps

[@KoleePlaysGames]

I also plugged my hdmi into my motherboard. I know it is probably obvious that you would need to do that but i had watched dozens of tutorial videos and not a single one showed them plugging the cables in

[@itashious]

I think instead of pc builder ripping new people a new one they should be offering helping hands and advice. Last thing I wanted to do was scare off my ten year old nephew cause he didn’t know what he was doing. Treat people with respect

[@Allustar]

Oh, so that’s why there are HDMI ports on the motherboard. Makes sense. I personally don’t have any integrated graphics in my PC though.

[@progamer3000-uz7pj]

It's not the case on every motherboard. Some boards redirect your graphicscards output if you have one plugged in

[@king077]

I did the same thing cuz the pc building guide i watched said nothing about plugging the hdmi to the gpu, so i just plugged it into the first port i saw, which was the motherboard

[@bhawk4233]

I did the same thing for a month until my friend fixed it, he was bewildered

[@greenRichard-e3j]

Ah same as my friend he plugged it in to the mobo HDMI and for hrs talking online nothing was solved until he took a picture of the back side of the PC

[@ZachDxn]

That's honestly crazy, do people not obsessively watch turorials on KZbin before attempting projects like this?

[@Eyedunno]

Would be cool if GPUs automatically downvolted/downclocked if you didn't plug in external power though. I bet a 4090 would still be pretty good on 75W considering how good my RTX 4000 SFF Ada is with far fewer cores than a 4090.

[@DemonSliime]

I have four 4090s overclocked and connect my vga cable directly to my mobo with lakeport.

[@tina1061]

I ordered for a custom PC. Was losing it when I couldn't see anything on screen. My tech friend who was on call, you sure that was the GPU? My noob ass now knew better 😂

[@AxleGenesis]

Ok so I use a server GPU to accelerate my inboard graphics, so this is actually a legit issue that I've run into when putting things back together mindlessly after a change. Because my HDMI goes in the MoBo plug, so if I forget to plug in GPU everything works fine but I have the power of a uhd760 integrated graphics unit

[@letsstartriding125]

Actually the pcie 16x slot can provide 75 watt of power. I tested it with a RTX 4070

[@Drewab133]

I feel bad for people running on integrated graphics

[@kizzanimations3024]

…now I need to check where my hdmi is plugged in on my computer since I didn’t even know you could do this lmao

[@dexsters5643]

Useally if you froget the powercables for the gpu. But have the monitor plugged into the gpu it shows on the screen "turn off computer and plug in requared cables"

[@mightyavengersgaming8530]

Recently I Purchased a Budget PC with iGPU (5600G+B450+16Gigs ram) for my Dad. I forgot To connected the 4pinPWM Fan connector... He Used his PC almost 6 Months without Spinning the Fan. I noticed it when I opened the PC for cleaning purpose 😐.

Atleast if fhe had a glass case then he should see if the gpu's fans were even running....🤦🏻‍♂️

[@mentosvagabond]

[@awwwman348]

Iam so glad i subbed to you i didn't know about this and i was playing with intergrated graphics im surprised some of my friends acutally could optimize my pc a lot for me to get a lot of fps in video games in reality it was only 60-75 fps but ey i guess it kinda worked

[@virgilevirgile9295]

If you actually can't use the gpu output, i think that some games allow you to use the gpu graphics with your cpu output (ex: watch dogs 2) which is actually useful

[@camerondavis640]

I feel like it should power on drawing the line 90w from the slot, just be power limited

[@camerondavis640]

But I know that’s not how it works

[@yodyl9811]

That one time I forgot to plug mm GPU in the fans just went WILD the entire time making it pretty obvious something was wrong.

[@Kenno10rapid]

We're allowed to make mistakes. PC's are not simple to most people and there's alot of places a mistake can be made.

[@7A7z]

no actually what i think happend is that the GPU was runing but with just like 75W trought the PCIE slot Acording to my knowladge database in my head GPUs can run trought the power of the PCIE slot and there are GPUs like the GT710 that run exclusively trought the power from the PCIE slot

[@mr.g354]

i spent an hour troubleshooting a pc only to find out the power button was stuck down.

[@captainbubb1278]

the only wrong thing youre saying is, that the gpu still gets power and outputs a display signal, saying that the power isnt plugged in. It gets a bit power from the motherboard, which isnt enough for graphics cards with an extra power connector

[@ytkartikfnhimself]

One time on my first pc build I literally forgot to connect my psu cables and it took hours for me to figure it out 😅😂

For intel streaming, quicksync still good. The workload should be on the gpu. I'm wondering how much vram game development eats while streaming.

[@The_majestic199]

some gpus like some modded or op 1050 tiS amd rx 550S can run like normal without the cable but then if u attach the power cable u get better performance

[@likrecelineation]

I don’t really see why anyone would make that mistake of plugging in the hdmi to the motherboard. Idk why, but even when I first started learning about pcs, I had already seen enough Linus tech tip videos where they show them plugging in the hdmi to the gpu to know

I just built my first gaming pc after not having a personal computer for nearly 15 years and I bought a graphics card without realizing that it required additional power. No problem right? Well it was when I realized the PSU didn’t have the extra connectors and was underpowered. $130 bucks later I’ve got a nice little system that I can play Truck Sim and fortnite on. i7 cpu and GeForce 2070 so I’m probably not running anything like Cyberpunk well with decent graphics

you do lose some performance but if all you do on the motherboard screen is watch youtube, discord chat and word docs the delay is not notisable. I think on my old rig that thing gave me a 10MS extra (at least ) delay/lag.

I only found it was missing after I opened the machine to check everything was connected properly. I’d love to have seen my face when I realised my graphics card was gone, I was so confused.

This is not as bad as one repair I did. Customer brought in her PC and stated that the mouse pointer looked like it was possessed by demons or something. I kind of laughed at this and took a look. At first everything was okay. Then after a few minutes the pointer started to shake and move around the screen randomly. This had me puzzled for a while until I opened up the case and saw what was wrong. Whomever had last worked on the PC noticed that the motherboard didn't have one of it's mounting screws installed. And went ahead and fixed the issue. The problem was he didn't make sure that there was a brass riser under that spot on the board. So they had literally caused various leads on the motherboard to randomly short out to the case. By far the most puzzling issue I've ever seen on first glance anyways.
