I had a bad power switch in my 450D case. If its not to old corsair will send you a new one. Are you sure the case power and led connectors are on it the correct orientation? Have you tried bios 2 for the hell of it?
If bios 2 still same issue then go back to 1 and press Cmos and power up with one stick of ram in A1see if it starts. Is the keyboard and mouse in the correct spots. There are others on here that will help. Put GPU in the top slot x16#1

All parts were ordered 13 Mar 15.

I have tried several different orientations
Have you tried bios 2 for the hell of it?
No, I will have to read up on it.
If bios 2 still same issue then go back to 1 and press Cmos and power up with one stick of ram in A1see if it starts.
I will try this.
Is the keyboard and mouse in the correct spots.
I have them on the back, plugged in to USB 3 slots.
There are others on here that will help.
Ok
Put GPU in the top slot x16#1
I will try this

I had dead power+reset switches (and power+HDD LEDs) on my Corsair Obsidian 750D, as well, out of the box. Fortunately this didn't waste a lot of time since I'd seen a number of user reviews complaining about the same issue. But if I had not already intended to mod the case this would have been the deal breaker. The chassis has beautiful looks and top-tier quality, but too many tradeoffs, too many compromises. I've de-branded the case and (after also having a Corsair PSU and some Corsair fans fail) I refuse to ever buy Corsair's overpriced junk again.

Anyhow - confirm your power+reset switches work, lol, it's a stupid problem but seemingly also a stupidly common one.

I just noticed the BIOS 1 LED is amber. When I switched to BIOS 2 it is amber. Not change with BIOS set to 1 or 2.

Ok... I removed all the hardware from the case and reconnected everything non-case related.
The mouse, keyboard and monitor still don't come online. No lights, nothing.


I tried everything drop4205 suggested.

I noticed the light green light on the disc drive.

The BIOS 1 LED is amber.

use the adapter that connects all the case connectors to the motherboard. All the lettering on the connectors will be facing up towards the top of the motherboard in the top and lower row. Cant tell by the pic you have which way they are orientated.Try reseating the cpu and check for bent pins on the socket

"use the adapter that connects all the case connectors to the motherboard"

I am not sure what you mean by 'adapter'. Would it have been in the mobo box or the case box? Thanks for helping drop4205.

Remove your motherboard from the case. Disconnect all the cables and remove the CPU, RAM and GPU as well. Inspect the CPU socket carefully for any bent or missing pins. Report back once you've finished doing so.
