Replacement video card takes 2x6pin but PSU only has 1 6 pin, can I use an adapter?

Yes, I am well aware that if a PSU doesn't have the right cables for the graphics card I should just get a new one, or that the replacement video card is so old that it takes 2x6pin I should get a new one. But can we ignore these ideas because I don't have the money to do either right now and I need a quick temporary fix.

My current graphics card is very broken, and my friend had a spare really old one lying around that I could use until I gather the money to get a new one. But since its so old, it takes 2x6pin powersupply cables and my powersupply only has 1 6 pin. In theory, I manage to find some sort of adapter, to make the 1x6 pin into 2x6pin would it work?

Yes I'm well aware that this sounds like the worst idea and its unadvisable, but I'm broke. All I want to know is if it would work.

Thanks :)

it works? yes
is it recommended? no
the PC is on the brink of death? k then... let's hope u have life and house insurance... coz PC might not be the only thing it'll damage...

when a manufacturer don't gave u enough PCIe connector, there's a reason behind this, this might indicate that the PSU itself are not meant to supply an electricity-eater [read: power-hungry GPU], if the manufacturer doesn't even support it, why would u go out of the way to fight it...
besides, the post above already state other reason, some PSU can't even supply wattage as it is rated for....



Thank you very much, I will order it :) !
 


What is your *exact* PSU and *exact* GPU? 9 out of 10 times -- maybe 99 out of 100 -- PSUs missing a basic connector are missing it for a very good reason, which is why you'll almost never see anyone recommend an adapter like this. These are almost always junk PSUs and if this is the case, there's no quicker way for you to end up with a second current graphics card that is very broken.
 


Meh the computer is on the brink of death anyway. Thank you for the info though. The PSU has plenty of voltage for what is required of it.
 


It's a horrible idea. As bad as it is to suggest adapter usage for this purpose -- which is why you'll almost never see anyone recommend it -- to offer this advice without even knowing what the PSU and GPU are is malpractice.
 


Well your choice is:
Use it - be prepared to buy another new card and PSU, but you can game, for a while.
Live without it - nothing will break, but you can't game.
Buy a new PSU - nothing breaks and you can game.

You already know the answer, but it's not the one you want to hear.
 


And it is nothing to do with voltage, it's current that matters..
 


That's not how you evaluate power supplies. How many amps on the +12V rail do you have? What is the new GPU? There are many "500W" power supplies that can't even run 200W worth of modern components.

Sounds like you just came here already deciding what to do, making the question a complete moot point, but hey, it's your PC and your house's fire insurance, not mine.
 


The PSU came with the case, I'm assuming its chinese and brand-less. The video card is a geforce gtx 570.
 


I came wondering whether it would work or not as I stated, I know how much of a bad idea it is. Desperate times.
 


Yikes, that can go 225W at load. How many amps on the +12V rail does it have? It should be written right on the power supply.
 


I can tell you later in the day when I have access to it, not with it right now. Sorry 🙁
 


Aha not everyone is a TomsHardware Pro like you are.

If you can't afford to replace your PSU, I would think that putting yourself in a situation where you may have to replace the PSU, the GPU, the CPU, the motherboard, etc. would put you in an even more desperate situation.

If you don't know the +12V rail (you still haven't given us the specifics) you shouldn't be putting *any* GPU in your PC. If you want to risk anything frying or in the worst case, a minor house fire, that's your business, of course, but you shouldn't be making this decision without knowing the basic information about *any* GPU installation.
 


Don't play all smart, you're the one who gave advice without doing your homework. Why would you *ever* give a recommendation to use an adapter for a PCIE card without knowing either the PSU or the GPU first?
 


The GTX 570 is a power hog.

My recommendation is not to use any sort of adaptors with that generic PSU.

You risk burning up your whole system and or starting a fire.
 


True. Soon enough I will buy new stuff but I can't right now, and also its my work computer. Lets hope luck is on my side.

 


Can you give me a probability in percentage that my computer doesn't turn into a firework? Guesstimate?
 


Maybe because I forgot to ask the question first? I think it's pretty self explanatory buddy. However, it's not like the advice I gave wouldn't work for a better PSU. I didn't give "bad" advice, just uninformed advice. Get off my ass, I understand I almost killed his whole system, I made a mistake.
 


Wait, this is your work computer too? This gets worse all the time - you're not just risking your PC that you play games on but your very livelihood? What CPU is it?
 


Likely not very long.

Could be right away, not way to really know.

Not worth risking your whole PC for, you could lose it all.

Take a picture of the PSU for us and post it.
