Replacing PLED / HDD LED - specs?

post #1 of 5
Thread Starter 
Hello,

I intend to replace the blue front panel power / HDD activity LEDs, as well as the hot swap bay activity LED, of my Silverstone FT03. Mobo is an Asus Maximus Gene, BTW.

I see some places that sell pre-tailed LEDs precisely for this purpose, so I may just go with that. Alternatively, I may just buy the bare LEDs and rewire the pre-existing connectors to them.

If I go for the latter plan, what spec LEDs do I need? Do I have to keep it under a certain current / voltage? What kind of power is supplied by the motherboard PLED / IDE LED headers?

BTW, I certainly don't want super-bright LEDs; I sleep in the same room as my computer, so just gentle indicator lights would be appreciated. What mcd LEDs would you recommend in that case? Or should I buy resistors as well and wire them in?

Any advice on how best to go about this would be appreciated. I have very little electrical experience beyond basic physics.

Thanks,
—Gabe

I just got the pre tailed ones. They were too short, so I just spliced them into the HDD LED wire and they work fine.....

I did not really pay attention to any specific power value. Maybe I just got lucky. I would imagine that any 5 or 3 mm LED should work fine. I could be wrong on that......

Thanks.

Further research suggests that LEDs rated for a max of 50mA are probably quite safe on a typical mobo PLED / IDE LED header.

Even if I get the pre-tailed LEDs, the hot swap bay LED is a separate issue (seems to be connected to a molex pin? I don't have the case in front of me), so I'll have to rewire a bare bulb anyway.

They have LEDs with molex....

Both of those are indicator lights; if you replace them think about brightness - which you don't necessarily need much of and may not want (annoyingly bright). IMO, shoot for 1-2000mcd which would still be pretty bright. I'd get the LEDs from someone like superbrightleds and solder them in - cheapest and you can order more while you're there if you want more for future projects (and get bulk 10+, etc discount).
