i have a 660 ti and a greenme650 psu,, so on the 660 ti , it has 2-6 pin connecters on it , i thought i had found the solution but i just tried the 2 6 pin connectes in the 1st slot on the gpu and the both 6 pin connecters worked in the first slot on the gpu ,, now i tried both 6- pin connecters in the 2nd slot on the gpu and neither worked in the secound slot so im thinnking my gpu is bad?
ok is my psu bad or my gpu bad?

GPUs don't have slots. Motherboards have slots.
What "2nd slot on the gpu" are you talking about?
Each GeForce GTX 660 Ti graphics card must have both of its 6-pin PCI-E power connectors plugged into the PSU.
How many GeForce GTX 660 Ti graphics cards do you have?
What is your motherboard brand and model number?
yea when i said slots i ment the 2 pci ports where you connect the 2 pci power connecters
the 2nd slot ,, is the 2nd place where you plugg in the 2nd pci power cable , the 660 ti has 2 places to plugg the 2 pci power connecters in, i was refering to that secound spot on the gpu

Both 6-pin PCI-E connectors on the graphics card must be connected to the power supply unit. The way that the graphics card draws power from the PCI-E power connectors is not distributed equally. Usually one of the PCI-E connectors will have a heavier power draw than the other.
I don't think there is anything wrong with your graphics card at all.
my pc wont turn on if i have the graphics card in ,,, it will work just fine with it out of my pc,, something is cuaseing my computer to not boot up when the graphics card is in my pc. thanks for the help btw
,, so i tested it to see if i could find anything out and the 2 - 6 pin cables both work in the 1st 6 pin connection spot but in the 2nd connection spot on the gpu for the 6 -pin connecters wont boot up at alli know both need to be plugged up but s\does it mean anything if the first 6 pin connection on the gpu the computer will boot up but not with the 2nd one connected ,, see my problem is if i connect both 6 pin connecters on the gpu my pc wont even turn on

How did you determine that the graphics card works with only one PCI-E power connector plugged into it?
I know the NVIDIA reference design GeForce GTX 660 Ti card draws less than 150 Watts so in theory it only needs one 6-pin PCI-E power connector. It's when you decide to overclock the graphics card is when the power consumption increases above 150 Watts and then you do need to also have the second PCI-E power connector plugged in.

i tested it by plugging both 6 pin cables into the 1st 6-pin spot ,and turned it on and it would boot up on both, now i tested the 2nd spot with both 6-pin cables , each by them selfs and nothing from that 2nd 6 pin spot .,, see from the 2nd spot on the gpu it wont even boot up i get nothing when i turn it on , i have tested it alot and get the same thing everytime

The graphics card is not designed to operate that way.
The first 6-pin PCI-E connector on the graphics card seems to be its primary power connector. The second 6-pin PCI-E connector appears to be used only when the graphics card's power draw exceeds 150 Watts.
You can try a different power supply unit. If the same problem occurs then your graphics card has a circuit problem. If the same problem doesn't happen then your In-Win GreenMe PSU has a problem.
ok thanks for the good info ,, i wonder why it would boot up on the first spot and if the 2nd spot is only used if the power is over 150w then why wouldnt it boot up if it isnt even useing the 2nd spot? i have a chance to send my gpu back , but you suggest try the power supply first? would you say the psu is the most likely reason?
by the way it was working good for 2 mounth then it just turned off one day, weird
dont have one
was thinking about buying one just to see what the problem is cuase its driven me crazy lol guess ill just send the card in and im sure they will let me know if it good or not and either send it back or send me a new one then ill know what to do ,, but thanks alot man!

no i had a exstra system but my mom pawned it awhile back , but yea what about going to bestbuy buying a psu and trying it out and if that dont work take it back and buy a graphics card? idk im getting desperate lol

Since you've already planned on getting the graphics card checked out you should just do that first before buying anything else.
