So I've searched through Google and it seems like the only thing I can find are people having the opposite problem I am. I'm putting my first build together and I've run into a bit of an issue with power cords. Pic related is the CPU power porn on my Motherboard (MSI Z270 Gaming M3). It's an alternating arch/square pattern for the pins. Yet on my PSU (EVGA 650 G2), I have a 4+4 connector where one side is the same arch/square pattern but the other is all arches. It also came with what they are calling an 8-pin+8(4+4)-pin CPU adapter on which both sets of connectors have the alternating arch/square pattern but the other end of the cable is some sort of weird connector with clips on the sides that doesn't actually attach to anything else.

I'd really like to not mess up my first build (not to mention all the money I spent) and would appreciate any guidance I can get.

youre in luck, i had the exact same problem myself.

did some sleuthing and it turns out that the all-arch shaped connector on the second set of 4 is designed to fit into different arrangements of pins. arches fit into squares, but squares do not fit into arches. therefore the second set is all arches so that it can fit freely into either hole.

i dont have the link handy, but i found a site that detailed the pins and voltage/power for all of the pins, and the layouts and the design specifications for them. so youll just have to take my word for it.

the 4+4 goes into the 8pin cpu, youre safe.

Thanks. Went ahead and plugged everything in and it all powered up.

Now I just need to figure out why my DRAM LED is on.

might just be the RAM isnt seated properly. you want to apply pressure at the far ends of the RAM (by the little latches) and try to get it to seat evenly.

take out all the RAM and put it in 1 stick at a time to be sure each slot works, and each stick works.

Alright, so there might not be an issue after all. If I let things run for 5-10 seconds, the LED goes out.

I'm going to start putting the cooler on and then put everything into the case. With any luck once I get the GPU in and get it hooked up to a monitor everything will work fine.

you shouldnt run the CPU without a cooler. ever.

you can put things in 1 by 1 to see if there are any issues. to boot, you only need the cpu (and cooler) and some kind of feedback (leds to indicate problems, or a pc speaker for beep codes, or some form of video out, if you dont have the first two.

it will boot without ram, but it should tell you that it didnt find ram.

id probably do GPU before RAM just so i was working with output. then do RAM 1 stick at a time. if anything comes up faulty, then figure out if its the stick or the slot.

add more components and keep testing.

your RAM led might be going out because it might be checking the RAM, and that is what the led means. double check your led codes in the mobo manual.

Just passing by and wanted to say to both of you, thank you for being the good part of Sup Forums that actually knows what they're talking about, and is actually willing to help.

Well I'm fucked for the time being. I can't put it in my case. The Corsair Spec-2 apparently only allows for flat cables to be run for the CPU power, since the cable has to actually run in the space behind the motherboad for about a half inch before bending over and plunging in. The cables that came with my PSU are all thick beefy braided cables that don't fit.

Now I need to go find a way to buy one single bloody cable for this thing. Many thanks to everyone who helped out.

so don't run it behind the mainboard then. just make sure it's not touching anything that moves and you'll be fine.
My 750G2 cables are fairly flexable. Are you sure you can't get it in? I'd say plug it in then pull all the slack into the main chamber of the case so you can wiggle it around.

i mean, you can run the cable over top for now, i.e. dont bother routing it behind the mobo tray. if its the only thing run that way it would be no issue.

also, you can usually get the cables into the spots they need to be before mounting the mobo to the mobo tray. that is sometimes all you need. though im not quite sure i follow what you mean about the cable fitting, unless there is just a really small clearance between the back of the mobo tray and that side panel.

if thats the case, that sucks. ive had the same problem before and ultimately the case was just too slim back there. - but dont forget, the cables in the braid are still cables. you can flatten it out a bit just by moving the cables apart with your fingers and then fastening them in place with a zip tie or something. i used duct tape to hold the flattened shape into place so i could then zip tie them. and in one instance i left the duct tape in place so it stayed flush to the mobo tray such that i could get the panel back on.

routing can be a pain. GL with whatever you go with. and mark down that case as being less than friendly.

in the mean time you can still test your components at least. get to installing your OS and whatnot. then do surgery when your extension cable comes in.

Cant. The way to MB sits in the case, there is about a quarter inch of space between it and the top and side of the case. It's jammed all the way into the corner of the case. There is one small hole BEHIND the MB about an inch in from the corner where the cable is supposed to comes through. If I went the other way, I would have to threat it around and over my GPU and between my PU and Cooler, and I'm not too keen on having my power cable in it's fancy nylon looking braided cover rubbing up against so much hot stuff.

it's fine. just don't let it hang into/onto a fan

My GPU is fucking huge. I'm not even sure my cable is long enough to snake around, and I'm not sure I have enough clearance between the side panel either.

For reference, this is how power is supposed to be run. This is from earlier in the week when I fist tried putting thins together. Turns out I had a bad PSU though. Amazon comped me by upgrading me to the next better model for free. And my dumb ass didn't keep the old cables.

you wouldnt snake around it, you just go over it and let the cable rest where it rests. it wont melt and there should be enough room between the gpu and side panel to accommodate the width of a cable.

ultimately your choice, obviously.

From what I can see the case doesn't have a PSU shroud. Just make a straight run from the PSU to the CPU power plug. it doesn't have to be neat and tidy to work. Run it over the GPU and round the heatsink. If it touches the fan shroud of the heatsink it doesn't matter, just don't let it touch the fan blades.
lel. guess they make corsair cases for corsair PSUs

It'll look like ass but whatever works I guess. Funny enough that's the side with the glass panel and I have it facing away from me anyway.

solid side panel>windowed side panel. Trust me you're not losing out on anything.

yeah that is a tight squeeze. that just seems like a very stingy case design (space wise).

you could still fit a power cable there if you routed it before placing the mobo in... but whether or not it would fit without some flattening by hand.

yeah, it wont look as pretty, but ultimately one stray cable is better than a rats nest. and it wont affect performance in any way (not even airflow, since its just a lone cable).

all depends. i would just get it up and running while waiting for the flat cable, if youre set on getting it. win/win.

yeah i agree here. but my first case or two had windows too. i think most first builds have windows.

The whole point was that I wanted as small a form factor as I could. I was originally going for an ITX build but was running into too many issues with being able to fit the GPU and PSU in any of the cases that I liked. The Spec-2 was smallish, but very light weight and came with a bunch of 140mm fans and I got it on sale for 30 bucks. If I had my way, I wouldn't get any glass panels at all, but like 80% of cases come with the these days.

Time to get all my peripherals hooked up and see if it will post.

i hear ya. i did a rebuild of a matx board and i tried to get the smallest case i could that would still support everything, and ultimately its not a very small case. its a small midtower, but still obviously a midtower.

best of luck with the rest of the build.

I got that same case for my girlfriend. I have the bigger version of it

>power porn
l-lewd

IT LIVES!!!

Wow, my fist ever scratch build done. Damn it has been one hell of a rough week.

>anything less than 1.5mm of sheet metal stopping you from finishing your build.
Get on my level user 1/3

2/3

3/3, also what the fuck is that shit on the screen in , it looks like eye cancer visualised.

UEFI

Always hated how ductile that sheet metal alloy was...like a fucking slice of cheese... Why can't it just be 6061 aluminium

Jesus Christ. The picture is my build from 8 years ago that I'm still using now, just with a couple upgrades (RAM and GPU) and in a nice proper case rather than a nigger-rigged server one that my employer was tossing out. I'm long overdue for a total replacement, but when I think that anything I buy now will have that UEFI shit on it it makes me not want to upgrade ever.

Fucking this, I can't describe how much of a pain was cutting out that hole for PSU vent, especially without proper tools. At least it's not something I would do very often.
