Custom Built PC Fails to show anything on monitor

[skelped]

I recently purchased a motherboard (ASRock 990FX Extreme3) a CPU (AMD Piledriver FX-8 Eight Core 8320 Socket AM3+) a case and PSU (Akasa Venom 550w Modular), and I was wondering where I'm going wrong with the set up; i.e if it's all compatible. I believe all those to be compatible but I also obtained an EVGA GEForce GTX 660 2GB GDDR5 Memory and also DIMMS- G.Skill 8GB Ripjaws X DDR3 2133mhz dual kit.

The problem I'm having is that when all this is connected and I plug it into a monitor (tried more than one and different types of connection) that nothing comes up on screen. I'm fairly certain that it is all connected together properly.

I think the issue could be the power supply? It's too low. (AMD CPU requires 125w and the GPU requires 450w and I only have a 550w PSU) But could this be why nothing comes up on screen? Everything does turn on except for case fans.

Or could the problem be something smaller such as the RAM I have are 2133MHz and the GPU states it can only handle 2100MHz? But wouldn't this mean that it would just run at its highest speed it can handle?

I am returning the PSU so i can get a high wattage one as this will need to be done no matter what the problem is.

Thanks for your help!

have you attached a buzzer ot the motherboard to see what error beeps it gives? try reseting the bios, ensuring that the RAM is seated correctly.

do you hear the dvd drive move itself after about 5-10 seconds? if so it means it has posted correctly and your problem would lie with the gpu

If you can get it working underclock your ram to 2100mhz you dont want to do that. Problem is most likely gpu or psu in a more you have bad luck case it could be the mobo.

Thanks for the fast response.
The RAM is seated correctly.
Yes the Optical drive does move and make a sound once booted up. So you reckon a dud GPU?
The ASRock motherboard annoyingly has no video connection options so I can't check this.
What about the PSU; would this not affect the ability for the GPU to display an image on screen?
I'm purchasing an Aerocool 800w 80 Plus modular anyway now. So I guess I can check if it is the overloaded PSU that's the problem.

Your psu is bad most likely could be wrong since im not there could you post some pictures it wont show the problem but i could get an idea of your system and further help.

i cant see it causing the gpu to not be able to display. if anything all that would happen is that it would shut down if you try to game. generally if it post's and no screen appears then the gpu is dud

Your motherboard doesn't support 2133MHz RAM. Try underclocking it.

P.S.: Your PSU is crap.

Hey ksham i already gave that. Thanks for repost!...

The psu is probably not able to handle that. Did you use pc part picker because if you didnt bad idea if this is you first build. If not its mobo or gpu. OR you didnt build it correctly.

That is not true. The GTX 660 has a TDP of 140W. It doesn't require 450W. The recommended 450W is for your entire system, not the GPU itself. With that said, your GPU requires a PSU that has one 6-pin power connector and at least 12 amps of current rating on the +12V rail. Your PSU comes with 2x 6+2 pin PCIe connectors and 45 amps on the +12V. Other than Akasa being a less-than-reputable manufacturer, it can support your GPU fine, as well as the rest of your components.
