Connecting components to power supply

[mindspin311]

Ok, I got a 2 pin Power LED cable in a 4 pin case (like the ones you plug into the PSU, with 2 empty spaces for 2 of the pins) with just a male adapter. I also have 4 fans with the same except they're all 4 pin in a 4 pin case with male and female connectors (split to 2 connectors m/f). Do I link all of these to the psu separately (not using the female end) or do I link them all together?

The way I have it set up right now is 2 cables from psu. 1 for PWR LED, and the other that goes to fan1, which connects to fan2, and so on...

I was also curious why the 9 pin(with 1 useless pin) connector on the motherboard has 9 (4x 2p + 1 useless) pins and my case has the little 2 pin female connectors for PWR, RESET, HDD LED, but no PWR LED. It is instead a bigger 2 pin adapter which is supposed to be connected to the PSU??


Now just 1 more.... My 8800gtx video card has (2) 6pin power slots right next to each other, and my psu came with (2) 6 pin -> 6 pin + 2 pin adapters.
Do i connect just 1 of them from the GPU to the PSU or both?
If just one, which one of the GPU.. closest or furthest from the back panel?
What do I do with the extra 2 pin connector?

Right now I have the 6 pin end connected to the PSU, and the other 6 pin end with the 2 pin connected to the video card with the 2 pin connected to nothing. This is connected to the furthest point from the back panel on the video card.

Any help would be greatly appreciated. I want to try to get all of this right before I power it up.

The LED question isn't that important. I mean it makes no difference in running the PC. What I really wanna know is the questions about the 8800gtx. Do I connect to both power adapters on the card or just 1? if 2, splitter from 1 PSU souce or from both 6 pin connectors to each on the card?

 

[mindspin311]

The manual that came with the 8800gtx is horrible. I mean it's not even card specific. Put card in PCI-e slot and secure and screw in.. if there's an external connection to PSU requried, connect it. Just basic stuff. I can't see why I would connect 2 power cables from PSU to GPU. That would defeat the purpose of it being SLI ready, so why is there 2 6pin power slots on the card? Do i connect 1 to 1, or fork it and do 1 to 2 with a splitter? and what is the extra 2 pin power adapter for?

Most modern PSUs offer at least one 6-pin PCI Express power connector whereas advanced models for enthusiasts are equipped with two to four such connectors. The GeForce 8800 GTX uses two external power connectors – you’ll probably need a splitter. You’ll have a problem only if your PSU does not have a single 6-pin power connector.

more 2 come ..

Can't find a 6 pin -> (2) 6 pin splitter.

I have 2 of these which came with the 8800gtx
http://www.newegg.com/Product/Product.aspx?Item=N82E16812200106

Under system requirements it says:

- A 450W PCI Express-compliant system power supply with a combined 12V current rating of 30A or more*
- One 6-pin PCI Express supplementary power connector
-or-
- Two 4-pin Molex power connectors

So only connecting 1 of the 6 pin connectors is required?? I'm confused..



Pretty much I have
(2) 6 pin PCIe Power inputs on PSU
(2) 6 pin PCIe Power -> 6 pin PCIe Power + 2 pin Power
(2) 6 pin PCIe Power -> LP4 splitters in the link above.

What do I connect from the PSU to the GPU?

Figured I'd simplify this since it's a bit confusing when I just rambled on...


((1)) Ok, I have 4 fans with LP4 (male and female) connectors. Do I link all of these to the psu separately (not using the female end) or do I link them all together? (PSU -> fan1 -> fan2 -> fan3 -> fan4 -> nothing)

((2)) I also have a HDD and DVD-Burner (both IDE unfortunately). Can I just use the same LP4 from the PSU I was using for the fans to link the HDD, DVD burner, and 4 fans together all to a single power souce?


((3)) I got a LP4 for the PWR LED that's missing 2 pins. Where do I put this? The PWR, RESET, and HDD LED all have smaller 2 pin connectors which go to a single 9 pin slot on the board.

((4)) I got a PSU with (2) PCI-e 6 pin slots, (2) 6 pin -> 6 pin + 2 pin adapters, and (2) 6 pin -> LP4 splitters (came with the 8800gtx). How do I connect the PSU to the 8800GTX with these?

Any help would be greatly appreciated. I want to try to get all of this right before I power it up.

Yeah.. I've read that. It's very vague and not card specific, so wasn't much help. From the picture you sent, it looks like ya got (2) 6 pin connectors coming from the main PSU that split from 1 wire. Mine only has a 24 pin, and a 8 and 4 pin for the CPU. The only splitter I have is the 6 pin -> lp4.

LOOK AT THE 3RD PICTURE THIS IS WHAT YOU NEED

I'll just use both 6 pin PCIe connectors on the PSU to connect to the GPU. Seems to defeat the purpose of 8800gtx in SLI, but w/e.

Just booted with everything else hooked up and the 4 fans aren't working. The case came with no instructions on connecting the fans, and most tutorials I've seen talk about hooking up a 3 pin connector from the fan to the mobo, and since all of my fans have LP4 connectors (split into male and female) I just assumed link them and hook it all up to the PSU using a molex 4 pin power connector.

I'm using the top middle one in this picture
http://images10.newegg.com/NeweggImage/productimage/17-139-002-09.jpg

I connect it to the PSU, and the far end to the PWR LED connector.
I then connect the middle part of the molex 4 pin cable to fan1, then fan1 to fan2, etc... until all 4 fans are linked. I boot up and the fans don't start. I turned off the power right away, cuz I didn't want to overheat anything. Am I doing something wrong?

 

[mindspin311]

Scratch that. Must've had a loose connector. All fans, LED's, everything works now at boot up. I assume the video card is working cuz I can feel the GPU fan when I put my hand under it, but I've hooked up my 22" Acer LCD monitor to each of the DVI ports, and I get no video. Nothing... I just tested the monitor on another system and it works.

Any reasons I shouldn't be seeing any video?

vidio card could be damaged...doh.
or not put in the pci slot all the way, check it.
try using a vga cable.
