hi so... i made a new pc build... but it wont power on

im guessing because i might have the pc cables connected in the wrong place maybe?

It's really not possible to offer you any help without more information. Specs? A few pictures of the wires? What do you think you did wrong?

[Rauten]

Yeah gonna need a lot more information; do you get any beeps? Do any lights turn on? Do you get any fan spin? Does your motherboard show post codes?

no no beeping... no lights turn on

Well there's your problem... You need to plug in the 20pin connector from the PSU into the motherboard.
The cable is the big one that's hanging off the computer case. The connector is to the right of the RAM.

I'd start with plugging in the power connector for the mainboard

Judging by that you thought that the ssd plugs into the psu, i would stop building the pc right now before you damage it, and instead try to watch a pc building tutorial.

But right now it seems you forgot to connect the 8pin and 24pin motherboard power cables.

 

Please read the motherboard manual or watch a tutorial.

I see another problem: the power supply. Such a low tier PSU and non modular too, not even semi. Get a CX750M or something.

Why would he waste money on that? The PSU he has there is just fine.

Where do you see an SSD on the pictures? They usually do have a 15-pin SATA connector, and thus need to be connected to the PSU, except it's an M.2 in which case I wonder how you would plug those into a PSU.

He's referring to a different thread by the same OP in which he was asking about how to connect a PSU to a SATA SSD.

[norritt]

@Rauten Ah okay thanks, didn't get that.

You're funny. That PSU he has there is a tier 5 PSU, closer to the hazard side than it is to good. At least something like a CX750M is tier 4 and in terms of being a hazard or being good it's medium. Personally had a CX750M for a while now, heavy use in a quad socket server and now retired to my normal rig, hasn't let me down. That EVGA pile of garbage won't last half as long as a CXM PSU.

1st of all 750W is *WAAAAY* overpowered for that build or most other gaming rigs you see around except those running SLI. You can expect that EVGA PSU to have solid build quality. It does exactly what the CXM750W would do - supply the computer with power. There is literally no real-world advantage of swapping that PSU with the one you mentioned. If OP has excess money he'd be way better of investing that into another stick of RAM, than in an oversized PSU.

That PSU has FAR worse build quality than a CX750M. Also the op's build's power draw is 749W, meaning he is 1 watt under the max load for a CX750M and 149W  over the load of his PSU that he currently has. Do you realise how dangerous this is? Yes a CX750M has pretty much the exact amount of power that the computer needs, but at least it isn't OVERLOADED like his current PSU.

To the OP: Your computer won't power up because you're overloading the PSU. Get a PSU that is AT LEAST 750W or greater. I can help you with that.

Miscalculated your power draw, read my last post.

[xriqn]

I would recommend this PSU for you, 250W above what you need but its better than having a PSU that is overloaded or maxed out:

While I don't believe that the CX750M buildquality is "far" superior I'm not argueing about relative build quality here. All I'm sayiong is that the OPs PSU build quality is way more than good enough.

That build's power draw is not even remotely close to 750W it is not even scratching the 500W mark. So no it is not dangerous.

Are you stupid? 1080 is 180W power draw EACH at full load and they have TWO OF THEM IN SLI. That is 360W in supply just for his graphics cards.  Recalculated his power draw anyway, turns out I went for 1080tis by mistake before, they're still over the 500W threshold (569W total power draw) and is pretty much touching the 600W limit of their PSU. A 750W PSU would be MUCH safer for them since it gives more headroom for any hardware upgrades (*cough* such as the 1080ti *cough*). Also a question for you: Do you have a multimeter at home? If the answer's no (which it probably is), then how the hell can you say that the EVGA PSU is of an acceptable build quality? These people who make and update the PSU tier list HAVE a multimeter and various electronic testing equipment and the results they get from testing a power supply on that equipment determines its tier in the list. In the EVGA PSU's case, I can safely say that it is NOT a good quality PSU.

Dude calm down and peel your eyes. That is NOT an SLI build there is a single 1080 in there. You can use a 450W PSU for that and still be good.

Well either way its a shit PSU. Garbage build quality, low down on tier list. It's a hazard. End of story.

[norritt]

It is a decent PSU now matter how much you love your CX750M. If you like it that much get one yourself and stop wasting other peoples money and time for no benefit.

[Cbfbrolol]

I agree with xriqn. There is soo much more to a psu than output rating. Protection circuits for a start (over volt, short circuit, etc..), ripple suppression,voltage regulation. Poor ripple suppression to within 50% of within spec (so for 12v rail spec is +/- 120mV) so a ripple of 60mV constantly can reduce lifetime of parts signifigantly. The closer you get to that spec limit, the more it can affect your parts and stability. Most low end psu will have poor qualiry protection circuits or complete lack of them all together. I have seen low tier psu's from name brands with ripple of above 50% of range of spec.

Yes but the OPs PSU is not a poor quality one, it offers good protection and also is overpowered by far for this build. This pretty much says it all:
