So I have gotten all parts for my computer and it won't power on. The fans fun, hdd turns on, disk drive powers up, case lighting turns on and is bright. But my gpu does not turn on. I called msi my motherboard company and they are saying I need a 450 watt minimum psu. I have a 430. Please tell me if I do need a 450 watt or if the 430 is enough. My specs are:

Msi a78m-e35

Amd Athlon x4 750k

Xfx r7 250

Samsung disk drive

WD 500gb HDD

8gb (2x4gb) corsair vengeance ram

3 1500-2000 rpm fans

1 cold cathode light

Cx430 psu

Please tell me if I need a 450 or larger psu.

A 430 watt power supply should be more than enough. Did you get everything plugged in? Everything seated firmly?

Yes everything is in firmly and plugged in. Just the gpu does not power up. I'm not sure if it is DOA or if it isn't receiving power.

yea you could easily get by with anything over 400 watts. Also off topic but I'd recommend swapping out the cathode for an LED strip to save space.  Never mind I didn't realize you already got it.

My System Specs: (Short list) i7 4770k, GTX 780, many SSD's, a 2 TB HDD(deceased :( ), Corsair 650D. Full list: http://pcpartpicker.com/user/kchriz6097/saved/8dh7YJ

Upgrade Plan: Acquire some Black Noctuas then add 16 or 32GB of 2133MHz memory

I agree. Doesn't leave much room for upgrades, but that will be enough.

It might be dead. Hate to say it, but it's a possibility. Could also be the motherboard, but not that likely.

Have you been handling the card carefully? You shouldn't touch the PCB and components too much or put the card on conductive surfaces. Discharging static electricity is also important.
