PC Won't boot with new GPU

Craftninja7 · Apr 15, 2017

So i bought an R9 270x today, an upgrade from my old GTX 550 Ti, and the PC won't boot with the new graphics card, and its not that it just wont display anything, my keyboard and mouse lights aren't even turning on. It turns on fine with the integrated graphics and the old gpu, and i've tried a lot of stuff and none of it has worked. Please help.

What make and model is your Power Supply (PSU)?

DRagor · Apr 15, 2017

Ok, so you have perfectly working systems, that will however not even boot with new card.
Did you connected all power cable(s) to the R9?
Is your PSU powerful enough to run the R9?
Is the mobo beeper giving any beep error code when trying to boot with R9?
Try booting with R9 installed but monitor connected to mobo.

My psu is a Visiontek 700w

Dragor, all the cables are connected and my psu is good enough, I don't know what you mean by Mobo beeper, and it doesn't show anything if I connect to integrated while the other GPU is installed.

That PSU manufacturer doesn't even appear on the trusted Tom's Hardware PSU tier list. A quick Google search came back with quotes like this:

"The VisionTek 700W looks to be anything but a 700W power supply. In fact there is nothing about the build quality of this unit that makes it seem like even a passable 500W power supply."

"What do you get when you combine an old design with extremely poor integration, corner cutting, knockoff/cheap components (Cheng/Chang/Chengx capacitors), and atrocious support? The VisionTek 700W."

I'd be willing to wager that your PSU is not good enough to power the 270x, and thats why nothing will turn on when you have it installed.

I think you're right, my old gpu only used one 6 pin and this one uses 2 and more power, so I do think it's the power supply. Thanks for your help!

"and it doesn't show anything if I connect to integrated while the other GPU is installed"

That's normal. The iGPU is automatically disabled while ever there's a PCI/PCIe GPU installed.

My new graphics card is actually Visiontek too, so if the Visiontek PSU is bad, the Visiontek GPU might be bad too.

No worries.

Please consult this list when buying a new PSU:

Stick to Tier 1 or 2 if possible, only buy from tier 3 if you really have to. Avoid anything else like the plague.

So it seems your machine properly detects that GPU has been installed, and all cables are good. Old card works, so PCIe slot is okay. While your PSU is not good quality, it runs, so should be at least able to boot with R9 onboard. Looks like R9 is not working.

As for mobo beeper, it is something like this: https://www.alibaba.com/product-detail/PC-Computer-Motherboard-Post-Code-Speaker_60215079360.html connected to motherboard, so it can give audible error codes when something does not work.

A bad GPU wouldn't stop the whole system from reacting at all when powering on.

No display signal, POST or boot failures, BSODs, artifacting, crashes etc. are things one would usually associate with a faulty GPU, but not complete power failure.

I'm looking at the EVGA 80+ WHITE 600w PSU, will that be good enough?

Craftninja7 · Apr 16, 2017

So I bought an EVGA 600w Bronze PSU, and that changed nothing. So either the psu is still not enough or my gpu is for some reason making the whole system not work.

You decided to jump into action before all possible steps has been taken to find out what is the cause of your problem. No real harm is done - you would need to change old PSU sooner or later anyway.
So let get back to my previous question: do you have beeper installed?

The link you gave me didnt work. Any other links?

Craftninja7 · Apr 16, 2017

Is the beeper a download or a physical product?

DRagor · Apr 16, 2017

Craftninja7 :

I already answered that question.

Craftninja7 · Apr 16, 2017

I'm considering just buying a crazy wattage psu just to test the gpu to see if it works and then returning the psu. The card was used so theres a possibility it doesn't work, but the fans spin.
