Yet another technical question....

I'm almost done with my PC, and I have one final question.

There are some LED cables in my case, for the power light and such, with nowhere on the motherboard to place them.

So, do I need another part to supply power to the LEDs, or do I most likely just have the port on my motherboard?

The motherboard is a ASRock M3A770DE AM3 AMD 770 ATX, and the case is a Rosewill DESTROYER 3x 120mm, if that helps.

Edit: Oh yeah, and if I need to order a part, it's gonna be alright to move on with software installation, right?

Thanks!

Assuming you have the manual: Page 10, #22.

If not, here's the location to the PDF: ftp://174.142.97.10/manual/M3A770DE.pdf

On Page 25 there is a more detailed description, it's called the "System Panel Header". The header has a selection of pins set aside for the "System Power" and "HDD Activity" lights, which is what I think you're talking about.

Not entirely sure. Having a degree of difficulty locating that specific MOBOs details. However, typical from my experience there is a small 4 pin near what would be the bottom right of the mobo on ASRock Mobos that can supply power to aux LEDs. However it seems more likely you would need to run directly from the PSU. Its just what seems logical to me. If I can find the mobo spec sheet, I will be able to respond again more accurately.

EDIT: I concur with Skorpyo's assertation based on the mobo diagram. If theres anywhere your going to ideally plug your LED array to its likely to be there. Ive built 3 PCs thus far with ASrock Mobos, and that pin array is always where Ive connected any such LED arrays (My current PC has two LED "eyes" on the front cover sheild along with a HDD activity sensor as well as an overheating LED indicator.

One other comment I will make is that lining the pins to the plug seems counter intuitive with ASRock Mobos in my personal exp as I think you can actually allow up to two separated plugs within that block and from what ive had to do in the past they lined up horizontally instead of vertically. May or may not be the case with this mobo.

Key thing is the LED array for the case should have plug ends already attached. It should seem fairly clear if that pin set is what the array is supposed to plug into once you visually compare them.

However, all this is assuming that the LED array is something that comes as a standard part of the case, and not something customized.

FINAL EDIT: anyway, Best of luck, and Kudos for doing a custom build. Every aggravation you experience from it, will equal a lifetime of knowledge that will benefit you in the long run.

Ok.
I'm taking a look at that, and the switch LEDs are three-pin female ends, while the others are all two-pin female ends.
It seems that the ends of the wires aren't the right size for the System Panel Header.

You can use a small pick to (carefully) remove the individual female pins from the connector and rearrange them to fit your needs, usually by pushing on a small metal tab showing through the plastic connector.

Couldn't say how to do it on your connectors specifically, but there should be a step-by-step somewhere online (Though I don't know where to look).
