No post with new GPU.

[Hallfrisch]

Update. realized I had got the 390 not the 370 while I was writing this, sorry to throw people off.

Rig needs a new gpu went with a [strike]xfx370[/strike] xfx390 but after installation no bios beep. Checked and still can load on integrated and the old one, AMD 6850.

MB gigabyte z77-D3H rev 1.0
PSU corsair 620w
CPU 2500k
Bios version. american megatrends inc F13 5-11-12

new gpu is a 6+8, I'm using the same power cords from the 6+6 AMD but one is a 6+2.
reseated the card a couple of times.
GPU fans spinning.

Do i need a bios update? Any other ideas, things to look at?

I have a corsair 620w,

Already looked at that. This isn't a new build.

If you had read that, then you performed steps 19-23? Those steps really don't matter if it's a new build or not.

Have you also tried another PCI slot? Double check cabling. It's ultimately possible the GPU is DOA or your motherboard refuses to recognize it. Does it boot at all using the motherboard graphics?

You did NOT read the MANUAL in your new card NOR the outside package. It specifically states

"External Power ­ 6­pins : 1
External Power ­ 8­pins : 1
Minimum Power Supply Requirement : 750 watt <<<<<<<<<<<<<<<<<<
XFX Recommended Power Supply : XFX 850W PSU" <<<<<<<<<<<<<<<<<<

Easy there. You linked a r9 390 Double Dissipation. The OP has a 370. 620 watts is more than enough here.

Yes the webpage does link automatically to DD, http://xfxforce.com/en-us/products/amd-radeon-r7-300-series#* Click the first top left model r7-370p-4sf5, which is the lowest end model XFX370, http://xfxforce.com/en-us/products/amd-radeon-r7-300-series/amd-radeon-r7-370-4gb-core-edition-r7-370p-4sf5 , which at the bottom SPECS says
REQUIREMENTS

External Power - 6-pins : 2
Minimum Power Supply Requirement : 500 watt
XFX Recommended Power Supply : XFX 650W PSU

But OP says "new gpu is a 6+8" - so reviewing ALL XFX370s, they ALL are only 6+6 NOT 6+8,
the only cards that ARE 6+8 (as I linked) XFX390, and the OP mistyped XFX370 for XFX390 OR OP has some weird rare OEM specialized edition NOT listed anywhere on XFX's website of the ONLY products it supports.

Tom has a point OP. What GPU do you have? I'm guessing you have a Corsair 620HX which does have 6+2 cables.

 

[Hallfrisch]

Sorry about that!! I do indeed have a 390, I was told by a fellow member here on tomshardware that my psu was good enough so unfortunately glanced that over. I'm not the most experienced with computers, forgive me.

Does it sound like it simply is only a power supply issue? I'm gonna look into a new psu, should i get anything more than 850w? I'll make sure to stick to the reliable brands but any other pointers or things to look out for?

 

[barto]

Well you should be fine with a 620 watt. The Corsair HX has 54 amps available across it's +12V rails.

The power consumption for a 390 .

I'm actually surprised your PC isn't starting. I'd at least expect it to start even if the wattage is on the higher side.

 

[Hallfrisch]

barto what am i to think then?

@Barto : I thought the same thing about my GTX 970, but the solution WAS to get a more powerful PSU (instead of the brand new 500W I had to get a 700W) and not had a problem since, ESPECIALLY with the PSU having the 'default right connectors' wired right in (no adapters) as I have the Refresh ATX which requires 4x2pin Power instead of ATX 4 pin for the Mobo.

Honestly, when they say recommended, that is what I go with as that is "just like we advertised and sold you on buying our product" standard. I would get the 850W. Better to be overpowered then.. well a computer that doesn't boot like you got now.

What PSU did you originally have? That just doesn't make sense though. There's reasons why benchmarks and tests are done to see how graphic cards perform. Manufacturers always overstate what's actually needed for a component. 970 GTXs can easily run on less than 500 watts as they only draw 150 watts. Trying to remember my power classes and one thing that comes to mind is start up in rush current. But even then it should be fine because good power supplies can output more than what's rated until the load decreases and flat lines. \

@Hallfrisch, You can try a new PSU. The Corsair HX620 was discontinued in 2010. It quite possible the PSU has just lived it's life and can't output higher end wattages.
