Hello friends! I have a question/concern. I finally built my rig last night, woke up this morning, took a quick look around the case. Made sure all plugs in adapters were where they were supposed to be and plugged her up fired her on but one thing did not happen. A boot. Literally nothing, no beeping no PSU spin, nothing! Proceeded to switch outlets and plugs, nothing. I will look tomorrow and see if everything is plugged in correctly and try again. I feel it may be the PSU itself. What do you guys think? It is a Corsair CX 750M. I want to make sure the header for the power button is in the right place just to double up. Please let me know what you think. SOrry if this is a braindead post but it is my first build.
Thank you in advance,
Danny

i've found corsair's quality to be in the toilet of late. i would recommend testing the system with another power supply. could be anything honestly, but the psu is a good place to start.

The Corsair CX series are not recommended. They have quality issues.

Do you have a case speaker for your motherboard? They are an important tool when diagnosing a computer problem. Do you have access to a multimeter?

After checking the power supply, I would re-seat the RAM and check the CPU installation for bent pins.

I know this is pretty obvious, but you have remembered to flip the switch on the back of the PSU before trying to boot your system? If you're sure you've done this then I guess it's a high chance your PSU is the problem ;D

I do have access to a multimeter. I am going to use it in a few minutes when my friend gets here as I never have used one. RAM has been reseated and the CPU has been checked for bent pins. My parts list is as follows:
CPU: FX 8350
CPU Cooler: Hyper 212 EVO
PSU: Corsair CX 750M
MOBO: Gigabyte GA 990FXA UD3 Rev 4.0
RAM: Corsair Ballistic Sport 8 gigs 1600 Mhz (2x4)
Case: CM HAF 912
Optical Drive: $15 LG
GPU: Diamond R9 270X OC
OS: Windows 8.1
Case Fan: CM Megaflow 200mm Blue LED

Which PSU would you guys recommend to replace this one? I am looking for high quality at a relatively budget price if it is workable, I am not looking to skimp as it is the most important part honestly. Can spend I guess $65-90 if it is workable. Looking for 700-750W with at least the 80% Bronze effieciency. I will post what I can with the multimeter later when I can test it.

Thank you for your time!
Dammy

If it is necessary, I would recommend a PSU by Seasinic or XFX (which is made by Seasonic).

Would it be better to go with a non modular PSU? This way I can only plug in what I need as opposed to having everything attached to the PSU? This is my first build so please forgive me if I have something wrong in my perception of parts.
Thank you,
Danny

I prefer the modular PSUs by far. It allows you to use just the power cables that you need. It cleans up the installation allowing for better cooling airflow.

The advantages of a regular PSU are basically that they are cheaper ($10-20) and it prevents the loss of the cables. The wad of cables apporaches the size of the power supply itself.
