Can A 6pin Pcie Draw 150 Watts

Can I use a GTX 780 with only the half dozen-pin power continued?

Both ability connectors need to be continued. You also need a better PSU for that video card.

Running my 4770k @ 4.2ghz and gtx 780 @ 1189 / 6900 with a 450 watt Silverstone PSU (same PSU Valve used in their steam auto prototypes).

EDIT: I don't know much nigh the OP's detail PSU though, so maybe his isn't as reliable as mine.

Just a notation on the pivot requirements. First if the carte du jour requires a six pin and eight pivot information technology will not boot without both. I accept forgotten to plug them in and wondered why my system was non booting. Basically unless you lot start modding the card here what the ability draws are based on and internal circuitry requires so much power to initialize.

No pivot means the card draws less than 75 watts and draws information technology all through the PCIe bus.

1 half-dozen pin means the card draws up to 150 watts, 75 watts over the PCIe buss and upwardly to 75 Watts over the six pin connector.

Two vi pins means the card tin draw up to 225 and needs a bare min of 150+ watts or it would just come with one six pivot connector. The added cost of the electronics for that 2d power line cost enough no company would add the second connector if it was not needed.

One six pin plus One eight pin can supply up to 300 watts, which tells y'all that the eight pivot lonely is supply 150 watts past itself, which is equally much every bit the 6 pin plus the PCIe express together are supplying.

Yous might get two six pins to work but I sure as hell would never apply that configuration as information technology non what the spec calls for. 225 vs 300 or 75 watts brusque. The card might simply depict say 250 watts just likely there will be issues. If the pegs that are missing are the grounds your insane since 250 watts that is not grounded is only a bad idea.

Though if you lot simply don't plug in the eight pin the system won't boot so there really is no question as to do it or non.

How many ways are at that place to say no?

Will I? The card requires 250W, significant ~21A on the 12V rail. The PSU provides 33A, and apart from the GPU, all I have in the auto is i SSD (usually under load, has Os/games on it), ane Hard disk (just storage), ane DVD bulldoze (rarely ever used), and 3 or and then low power fans. Even if nVidia was bourgeois with the power requirement figures (which I doubt), it looks similar I have plenty of headroom there.

Y'all MIGHT be able to get away with using that card for a brusque time with that PSU, but it will burn out quickly. 6 pin PCI-e is rated for 75W, and viii pivot is rated for 150W. A unmarried molex is but rated for 35w, and then even if you run a dual molex to 8 pivot you are nevertheless trying to pull at to the lowest degree 150w from a source that is just rated for a MAX of 70w. Get a skilful 550w - 650w PSU for your rig and call information technology a 24-hour interval.

For reference, my 3770K machine has a 1300W platinum PSU, the X6 rig has a 750w silvery, and the dual CPU ane has a 1000W gold PSU.

Its no good pairing a Penryn dual core with a 780..its just a waste matter.
Time for a platform upgrade.

Just it seems similar a catch-22. "Sell the 780 GTX, buy new motherboard, processor and RAM . . . " Graphics carte du jour? The OP should also consider keeping the card, selling or recycling her old CPU-mobo-RAM combination, and edifice a Haswell system with a motherboard that either matches or foresees her needs. This in addition to the PSU.

I detest to see people facing these sorts of crossroads, although I do information technology all the time. Merely "all the time" means that I target household hardware for upgrade, schedule the purchases over a several-month fourth dimension-horizon and take my time putting it together. If a person isn't computer-obsessive, situations similar this hitting y'all without warning.

I recollect he is off to a skilful commencement if he wants to have a very overnice PC. The 780 is ane of the most important and expensive components. Kickoff he volition need a PSU and and so he could at least game on it while he saves up for a haswell combo. MicroCenter has some amassing deals. You know he might could choice up a proficient bargain on used HW. ivy bridge or sandy 2500/2600k or 3770/3570k. Compared to the GPU, these things could be scooped up rather cheaply.

This is a practiced place to commencement, if he decides to build him up a powerful gaming PC. But showtime off, get an appropriate power supply

Link to source? That paradigm doesn't actually say anything (not saying yous're incorrect, that CPU is ancient)

I'm certain this has been said more than one time, just you need a new PSU before you can employ that card.

Yous also

want a new CPU.

There is nothing on that socket that will properly run a GTX 780. Recollect, you're talking about i of the fastest video cards ever made, and a socket that was abandoned by Intel in 2008. Your chip was introduced in January 2008. I remember it fondly...I bought it the month it was released. I ran it with an 8800GT, released in Oct. 2007, which had 1/6 the ability of a GTX 780. That was a pretty practiced match for the e8400.

So, every bit to the minimum system you'd demand to back up the GTX 780...I'd say an Intel i5-4570 plus a B85 motherboard, ideally with 8GB of DDR3 RAM. So that'south roughly $200 for the processor, $75 for the motherboard, and $75 for the RAM. The total comes to $350, and I'd say information technology would be money well spent.

an overcooked q9550 with ddr3 is on par with commencement gen i5s. an overlcoked Xeon equivalent at four.two-iv.6ghz is even more powerfull (if your using socket 771 to 775 adapter) Ane user on overclock.net even test a gtx780 on a q9550 with a moderate overclock on ddr2 and little bottle necking and adept frame rates.

I have a 850 watt PSU with four of these connectors,

so what i take is 2 150watt 6 pins with 2 wires tacked on just incase the GPU checks for 8 wires.

I desire to know if the GTX 780 will post and run with 6 capable 150watt pin connectors. (say my those footling extra wires broke/brutal off all four connectors and i'm down to the 6 pins.)

how does someone just get a 780 as a gift out of the blue? that actually makes no sense. the person buying that would have to have had some reason to think you wanted that.
