In need of a PC WIZ

KittyJaney · 3 Nov 2014 at 14:34

Hello!

Friday, my bf bought new parts for a PC, so he wouldn't lag in games anymore

We assembled everything correctly, but the PC starts and turns off constantly when the GPU is inserted.

PC spec:

ASUS Z97-p
GeForce 660 GTX
Corsair RM 650
Kingston HyperX Beast 8GB
Kingston SSD 120GB
Corsair graphite 230t

Things we've tried:

-Tried taking out the GPU and use the integrated and it works.
-Taking everything out, and leaving only the GPU in, turns on turns off
-Tried the GPU in another PC, it works
-Taking all the cables out, and putting them back in, no luck
-Looking at the CPU to see if any pin was bend, nope
-Looking all over the internet for answers, and most of the people say that it's the PSU or it's cause the MOBO has integrated graphics, and won't recognise the GPU
-Tried disabling the integrated in BIOS, but it doesn't work
-So we tried flashing the BIOS to the newest, succesfully installed, didn't work

Please help!

Do you know what power supply is in the machine? I've seen this twice. Once the psu was too low powered, just turned off a few seconds after posting the bios. Second time one of the PCI-E power leads was damaged, casing split, could see the wires. Changed that to another and the system started fine.

As the GPU works in another machine:

Have you selected the GPU in the BIOS when it's inserted?
It will try to use the GPU but as it's set to use the IGPU it will crash.

The 660 isn't the best card 'for not wanting to lag' so might be a hidden blessing to grab a better one!

darknite: it's Corsair RM 650 W, and the GPU worked with 550 W PSU in the old spec,
and the spec we bought needs only like 400 W to work, so it's just GRRR

ThaReaperGuy: it doesn't even come to BIOS when the GPU is in, it turns on, turns off in a matter of seconds

Take the PSU for the system it works in and use it temporary for this one to rule out the PSU you have bought.

I wouldn't put much faith in a RM PSU! :eek:

Just did it, doesn't work

Try the 2nd PCI-E on the board, should be the black one?

KittyJaney · 3 Nov 2014 at 15:06

We tried that too , no luck

DaleTheWhale · 3 Nov 2014 at 15:11

Do you have another GPU to test in the board, pointing towards the board being the issue.

KittyJaney · 3 Nov 2014 at 15:15

Yep we did that and it doesn't work
and yea, some people have problems with the Z97 and they flashed the BIOS and it helped them but not us..

How many pci-e power leads are with that psu? Try swapping them. Even change the order they are plugged into the card. Believe the gtx660 takes 2x 6 pin?

Try different ram

KittyJaney · 3 Nov 2014 at 16:25

searched the webs again and some dude said it was cause the PSU is not compatible with the new Haswell processors. forgot to put that in the list also! sorry ><

if its working with igpu and not the graphics card I would have thought it was a bios issue?

you sure you flashed to the very latest bios?

I doubt its a psu compatibility issue. That list is quite old and the RM are fairly new units in the corsair range. I had no issues using a much older HX 850 from corsair.
