So I just got my new GPU MSI GTX 770 but am having difficulty. One of the 8 pins will not go in correctly. No matter how hard it is pushed it will not go in all the way. I thought i got it in and pressed power but my comp won't turn on which i guess is because its not in all the way. Some pics

Odd, usually 4+4 pin connectors will clip together so that they remain flush. What make and model PSU is it?

Also, your carpet is absolutely disgusting.

Nope....Apparently you don't have (2) 8 pin cables on that power supply.....and most of us would NOT be comfortable using adapters to make this work at least not for long term

It can, but you need to have a molex to 8-pin adapter for your second PCI-E power connection. Your PSU only have 1 6+2 (8-pin) PCI-E connector and one 6-pin PCI-E connector. As I said, the connector you are trying to use, is a motherboard connector (EPS/ATX 12V). This is your PSU:

These are your connection options:

omg. Dont.... Hope everything's ok still. Probably is. The card didn't come with molex adaptors? They work fine.
 
If Iit is not labeled PCI-E like the other cable, then it is not meant for a video card. 4+4 is a motherboard cable, I'm actually surprised you got it in at all because I thought the shapes were different for the different connections. A+ for effort but sorry, PSU won't work.

Why does a 770 need 2x 6+2 when my 780s only need 1 6+2 and 1 just 6-pin... Molex adaptors will be fine on that psu. Also my 780s came with the adaptors in the box.
 
i do not understand people really, that PSU have 1x 8PIN PCI-E Cable and 1x6+2Pin PCI-E cable.. so it should be able to make it work without any kind of issue..

It SHOULD come with that... but they were dumb and only included 1 6+2 and 1 plain 6pin cable with this psu model... weird.

It doesn't. The 8 pin cable he's trying to push into the GPU is an 8/4-pin 12V EPS/ATX motherboard cable.

yeah i know thats the EPS 4+4.. but that PSU have 1x8 Pin and 1x6+2 i've had that PSU like 2 years ago and came in that configuration.. also its mentioned in the [H] Review..

The 8-pin and the 4+4-pin are ATX connectors, not PCI-E connectors, so they don't work with GPU's. As also shown in the [H] review:

reading its fundamental :eek:

Overall the picture painted by the Seasonic power label is that of a good modern midlevel power supply. The unit has ~93% of its DC output capacity available on the 12v rail (there is only one as there is no OCP set on the individual "rails") which is good for modern systems. This single 12v rail due to no OCP settings is similar to what we saw some time ago from the S12II 500W and really not that unusual for Seasonic units (why they continue to be labeled dual rail units though is unknown). This generous single 12v rail is coupled with the nine Molex and six SATA connectors for all of your peripheral needs as well as a pair PCI-Express connectors (one is an 8-pin PCI-Express connector) for your new single Fermi card builds should be inclined to go in such a direction. Overall though, this unit should satisfy the vast majority of users' connector requirements.

Maybe with image?

that PSU indeed have ONE dedicated 8PIN PCI-E and one 6+2 PIN PCI-E
 
well i got it all connected but when i press the power button nothing comes on
 
Reading is fundamental. Pair means two. In the review, [H] states:
"a pair PCI-Express connectors (one is an 8-pin PCI-Express connector)", meaning there is 2 PCI-E connectors, one is 6-pin, the other is 8-pin (6+2). So does the chart say:

1272633703oxXJd2Y0gS_2_7.gif


Note that there is 1 PCI-E 6-pin and 1 PCI-E 8 pin (which is the 6+2 pin PCI-E). Also note that there is 2 4+4 pin, which is actually 1 4+4 pin and 1 8-pin and those are ATX/EPS cables. On the chart I provided on the previous page, you can see this even more clearly:

did you connected the 4+4 EPS cable to the motherboard? yes that 4+4 Cable you was trying to connect to the GPU.. right in that place:

Should be apparent.... the 780 is a different, much more efficient architecture.

yeah its plugged in

Then its time to troubleshoot. I would disconnect all cables, except the 4+4 pin for motherboard, the 20+4 pin for motherboard, the 6+2 pin for PCI-E and the 6-Pin to 8-pin PCI-E adapter for GPU. Do an extra check to see if those cables are seated properly. Of course, keep the fan cables for the CPU on as well. Do a bios reset and see if it starts.
 
Nevermind fixed it. The PSU power cable came lose. Once I plugged it back in it worked fine.

Great! :D

Don't worry about the PCI-E 6-pin to 8-pin adapter. The cable difference between a 6-pin PCI-E and 8-pin is an extra ground wire. The adapter provides this and makes it possible to draw the 150W vs. the 75W 6-pin. Your PSU have enough AMP and Wattage to power this card over the 12V rail also. Love Seasonic PSU's. :D
 
ok im confused...did it have the appropriate cable or not...not calling anyone out on being a dumb ass or anything...but it appeared to not have the correct cables...or so that's how it was described to be...the listed wattage was borderline at best
from the way the issue was described..it appeared to not have the correct cables..or were you just using the wrong one?
 
Those adapters look like the right way to go connect the 6-pin header from the PSU on one end and the video card on the other.

No, his power supply didn't have the correct cables to get 2 8-pins PCI-E connections, but he did get a 6-pin to 8-pin adapter with his GPU that worked with his 6-pin PCI-E connector. The 8-pin connector that some suggested could be used for GPU is a 12V EPS motherboard connector and isn't compatible with PCI-E (won't even fit as the 4+4 pin ATX/EPS didn't fit either). :)
