Pc does not power on at all

[Ropnolc]

So I've been fiddling and fidgeting with all these new parts, namely and most importantly in this case, an ASUS H97I Plus within a Silverstone Sugo SG08 and it seems that I can't get the PC to power on.

I've made double sure that the front panel wires are all connected to their respective pins.

Here's a picture of the front panel wiring

And the diagram of where they should go from the instruction manual

I've ruled out the PSU as the culprit.
Because this LED on the mobo lights up when plugged to an outlet.
The LED signifies that the mobo is receiving sufficient power

I'm completely stumped right now, any help would be greatly appreciated!

try reseatting the memory and video card. also have you check your motherboard's website for compatible memory list?

Check with your case specifications and make sure the cables are what you think they are (mistaking the power led for the power button kind of thing). Also, just because the psu can make a light come on on your motherboard doesn't mean that the psu is good... If you're careful you can bridge the power and ground pin (the same pins the start button connects to) on your motherboard and it should start up, be really careful here since although there isn't much you can do to damage the motherboard by bridging the correct pins, things have a way of going wrong if you don't take things slow and know what you are doing before you do it.

Also, re-seat all of your motherboard power connectors. Unplugging all of the items in question and coming back later and reconnecting everything while being careful to stick to the documentation is also helpful for those times you get stuck.

One other thing, it's possible that your power button is broken on the case... just something to keep in mind. If you have a reset button, using it will normally start the computer if it's setup correctly.

I've made sure the connectors are all in place. Especially the front panel connectors
I have noticed something very strange though.
everytime I plugged it in and hit the power button, the GPU fans would budge slightly. Nothing else seemed to move though.
I decided to remove the GPU to see if anything would happen but nothing, nothing moves, and nothing lights up.

I've tried reseating the RAM as well and nothing came of it either.

Do you have another PSU that you can test the machine with? Or do you have a known working machine that you can test using this PSU?

Do you have the 4/8-pin CPU power plugged in correctly? A PCIe 6+2 pin connector will plug into the CPU power socket but +12V and Ground are on the opposite sides, grounding the +12V and giving the symptoms you're seeing.

The PSU came with the case actually, I didn't even install it. Though I suppose it is still possible that it may be faulty from the box. But sadly I don't have any spare gear to test it out with.
Thank you so much for the suggestions though!

I'll try messing with that in a bit!

I'm afraid the 4/8-pin CPU power connectors were in just fine.
I've tried with both or just one 4-pin connector(on either side) but the result is still the same.

What are your computer specs. I suspect you may not have enough watts for your new parts and may need a better power supply. And it is possible something is shorting the mobo. Have you tried a out of case test?

 

[Ropnolc2]

I'm fearing the PSU may very well be the faulty part here...
I don't know how I could have possibly damaged a pre-installed PSU unless it was already shot to begin with, which is ridiculously unlucky.
I'm going to dismantle the whole thing tomorrow and take it to the retailer and ask to test the PSU out(and get a replacement through warranty if it is in fact busted) in the near future.

Thank you all for your help and sorry if it was a waste of time to any of you.

 

[John Floyd]

yes but if your new parts are in need of a'lot more watts then you could have stressed the psu too much and caused it to blow. or it just shuts off because its not strong enough to power the new parts

is 600w too weak for these?
(I swapped the optical drive for a slim after some clarification)

 

[John Floyd]

You should be fine with a 600w psu so it may be bad

Short the pwr and gnd pins (with a screwdriver) on the system front panel connector. If it turns on then the connections from the front of case are on the wrong pins on the front panel connector

 

[John Floyd]

The power switch connectors are not polarized meaning it wont matter which was they are plugged in. but please note some of the connections are. But you could still try to short it with a screw driver to see if it works because the button it's self could be broke
