new GPU: pc doesn't boot

[Evrion]

I just received a new GPU: rx 480

 

https://ca.msi.com/Graphics-card/Radeon-RX-480-GAMING-X-8G.html#hero-overview

 

Put it in my computer, and it does not boot at all (no beeps even) black screen, then no signal after a bit. The card has lights and fans that do light and spin.

 

With the old GPU it still works fine (using it now). When it boots normally there are beeps before I get the BIOS screen.

 

Current parts:

mobo: P67a G43 (original BIOS)

CPU:  i5 2500k

PSU:  xfx 550w

 

details:

Causes I've thought of:

 

1. BIOS needs an update (thought I saw this for some other people with similar parts)

2. GPU is DOA

Did you plug in the power connectors for the card?

Even if the card was DOA the pc should still boot with it installed

sounds like a power issue.

now there is a problem with the RX 480 that involves drawing too much power from the PCI-e lanes which could be causing a problem, last i heard AMD did put out a fix for it so i would start looking into that

um, this was back in like July lmao.

 

Even then that wouldn't cause this issue.

i know this was back in july, but that doesn't mean that the card is a newly manufactured one could have been one of the ones made in the first month without the fix, we have no way of knowing that because the information wasn't provided and thus not ruling this out

if you want to bring this up............ before this was an issue with the 480, who actually looked beforehand at any other cards, regardless of manufacture? and who is to say that this wasn't an undisclosed problem for longer than meets the eye? and where was it ever measured that motherboards don't supply more than 75watts if a card will suck up more than that from the bus?

I don't think that's the problem.

OP, did you reinstall the old card and try to boot?

The old card works fine, still.

 

The old card uses two 6 pin connectors. RX480 uses 1x8 pin

 

My PSU has a single cable with two 6+2 pin connectors, so I used that cable for the both 6 pin in old, and a 6+2 pin for the new (tried using both connectors, neither work).

[LabRat]

can you try the new card in someone else' machine?

[Evrion]

no, I can't, there is no other PC I can play with.

 

I was thinking of bringing it all to a local PC shop to see what they find.

[LabRat]

I'm thinking a bad card or under whelming PS.

no friends with computers?

At this point, you really have to just troubleshoot.  We know it is the card.  Are the fans spinning on the card when the computer first boots?  Do the plugs going into your 480 say VGA on them?  You must use VGA cables going into your card, others wont work.

BIOS update fixed it!
