Power To GPU

Go to solution Solved by minibois,

So you mean you have a PSU with only one 6+2 pin PCIE power connector, but a GPU with with a 6+2 and 6 pin connector?

Best case scenario it will run, until you are fully loading the GPU in a game and it will crash, worst case it won't start up at all.

 

Don't do this though, if your PSU only has one PCIE power connector, it likely is not of sufficient quality with a beefy GPU.

I know i have enough power to power it iv ordered a molex to 6pin for it which apparently will work

molex to 6 pin is not recommended, not for a system you care about.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

How many watts do I need? ATX 3.0 & PCIe 5.0 spec, PSU misconceptions, protections explained, group reg is bad

why what will happen? also its not perminant just for a few weeks

 

The power delivery of molex is not appropriate for a power hungry GPU. Anything from the PSU dying to cables melting is possible. I speak from firsthand experience

how long did yours take to meal or your psu dying also its a 2xmolex to 6 pin if that makes a differance

I was running a 780 off a PCIe 8 pin + a dual molex to 6 pin, that was the death of both the PSU and the motherboard. When a crappy PSU dies it usually takes something with it.

the integrator is a super cheapo model. definitely not recommended.

Maybe you could put the power limit to like 50% or so so you shouldn't overload it but can enjoy it for the time being? :)

980 my friend has been using a molex to 6 pin for almost a year and it worked fine and he has a 980 also

Some win the gamble, some lose. I choose not to gamble at all.
