Old/New Build just connected, no boot...

[BillyF]

Hello guys.. after 2 weeks I've got my order of:

Radeon 7800XT, Corsair PSU 750W RMx and Antec case

My old parts:
CPU: i5-10400
MB: Asus Prime H410M-E
16GB RAM

I have connected everything according to many videos I have seen and asked in the forum.

Also, I have added an nvme from other PC I have (HP Pavilion desktop) which has Windows installed.

I have connected also my 2xSSD (old SSDs) which stores my games.

I just turned the pc on, power is working, MB has its led's on, the RGB fans are working. the GPU also has led that working.

But nothing pops up. no boot, no motherboard logo, nothing! but theres is no beep or like ALERT sound...

im so disappointed and worried as It's my first build im making myself, it might sound stupid but it took me 7 hours to put it all together...

What have I missed?

Thank you guys....

is it a 10400 or a 10400f? integrated graphics would come in handy : unplug the mains, take out the cmos batt for 10 secs, then connect back in and try to boot with integrated gpu, with the monitor hooked up to the motherboard itself of course.

It looks like you may be missing some of your CPU power cable there. only 4 pins are plugged in, but it looks like the motherboard is set up for 8. It appears the other 4 are just floating in space there.

As stated above, connect all 8 pins of that CPU power connector. The PC should post then.

+1 on the CPU power there, try it again w all 8x pins connected.

If no boot after that, pull the graphics card out and 2x check your front panel connections.
If they're not plugged in correctly (wrong location, +/-s are flipped etc) it won't boot either.

It also looks like you only have 1x RAM module installed - is that just 1x16GB or did you remove the other 8GB module for testing purposes?
Not having memory operate in dual-channel will affect performance so FYI just in case (disregard if this was just for testing).

Notes with that motherboard:
*1 When a device in SATA mode is installed on the M.2 socket, SATA6G_2 port cannot be used.
*2 A chassis with an HD audio module in the front panel is required to support 7.1-channel audio output.

If you check OP's system specs:

Memory	Crucial 16GB (2x8GB) DDR4 2666Mhz

Ok so for the CPU its 10400 and it has its own HDMI port, I have connected it besides the GPU connection - Still the same.

For the 8 pin connector - Ive got cables along with the PSU, BUT:
When I take the CPU cable, one side plugged to the PSU, the other cannot be connected as whole, only half of it can enter. The "build" of that 8 pin is similar to the build on the PSU, so, I can take the other side of the cable which connected ro the PSU and plug in to the MB as whole, but then - the other side does not fit the PSU!
I really hope I explain it well but you cannot connect it...

For the RAM - Its a 2x8GB but they aren't the same, one is generic Crucial and its color make it seems empty, the other is a Kingston HyperX Fury.

P4-630, Im sorry mate but Im pretty newbie and I didnt understand what you mean..

If you watch the cable closely on the right 1 you will see on one side 2 squares on the middle-upper
And 2 squares on the sides-down

This fits as whole to the motherboard, but then the other side doesn't fit the PSU, and the opposite - It fits the PSU but then the other side can connect only half (4 pins)

I must mention that the PC the motherboard came from, had a generic 500w PSU - and it was connected in 4 pins also :x

Edit:
Added PSU picture
Thanks for the support guys..

Don't flip the cable around. the split side (two 4-pin parts that separate) goes to the motherboard, you just need to plug both sides in. your motherboard manual confirms it is an 8-pin connector. If it doesn't work with your motherboard, you may need to reach out to Corsair and have them help you verify that the cable is correct.

With how you plugged in the EPS power, I could see the board being fried or the PSU shutting off for protection.

Also.. what is with the bottom fan pulling air from the GPU and the daisy-chained GPU power?

Omg does it mean the GPU is gone?

The PCI-e cable had a split 8 pin so i connected them to the GPU, I was thinking if I need to plug 2 cables to the PSU and then separately connect it..


As for the fan it's a built-in and yes it does seems wrong I was mistaken here again maybe by choosing this case.

I shouldn't do that by myself I guess

Unlikely it just looks like you didn't plug in the EPS cable correctly in the top left corner for CPU power.

For the gpu it's usually recommended that you use two individual pc cables just zip tie the daisy chain portion.

I'm abit confused, the cable for the GPU is connected ok?

As for the CPU connector, there is no way to connect both 8 pins of the motherboard and PSU with 1 cable. each side of the cable is different while the 8 pin connections on both PSU & MB are same.

If I use 2 cables connected to the PSU when the other sides goes to the 8 pin as split, like.. only 4 pin that fit. lol that's weird.. would that work?

The EPS cables splits into two 4 pins both need to be plugged in for the PC to boot.

You need two individual pcie cables plugged into your psu running to your gpu. Using the daisy chained portion on a 250w+ gpu is frowned upon.

Understood, I'll use 2 cables then, if I haven't fried it already lol..

The EPS cables won't work if I use 1 also, I can use 2

This might help

When you have time take a picture of the eps power slot without a cable plugged in.

Thanks mate it does seem like 1 side of the cable is fine but My CPU cable side which splits and supposed to be connected to the MB does not fit as whole, the other cable is exact same. Other cables I got are another daisy-chained PCI-E and 2x SATA cables (6 pin)

 

[Toothless]

Your PSU comes with two EPS. Try the other one. Also has four PCI power which is probably two cables with pigtails. Run the two dedicated cables for GPU.

Also flip that bottom fan for the love of everything holy. Give the GPU air.

alright, I will use 2 Pcie cables then!

for the CPU Cable - the other one is still the same.

if you watch the pictures you will notice each side of the cable is different while the connections on both PSU/MB are the same...
I mean.. what is going on? How is that possible?

OK UPDATE!

I managed to plug the whole 8 pin to the motherboard and the PC starts!
Thats my stupidity again..

The PC is working now but the GPU is plugged out, also the old SSD's is plugged out. only the Nvme with Windows is connected.

When I plug in my old SSD's which has my games and apps the PC dont start again and then "Beeping" (I must mention that the ssds are fine).

I haven't got forward to plug again the GPU cause I want to go step by step now...


Thanks guys..

I have managed to start the PC without the GPU but it wont start when nvme+old ssd connected. its beeping, is that what you meant?

does it mean I cannot use old sata ssds with a new nvme ssd??


LAST UPDATE !!!

Everything is working guys! Nvme+Sata ssd's and the GPU is now plugged and seems to work fine.

It was my mistakes and lack of knowledge and I thank you very much for the big support!

I just have to "re-wire" the route/path of the drives because now my apps/games ain't working, but that shouldn't be a big issue I guess.

Happy you figured all that out it can be tough when you have little or no experience doing it. Always a good learning experience.
