[Solved] 280x Not Posting!

[Zheka]

I have a bit of a problem here and want to know what you guys think, before I start ordering parts I might not need.

 

Issue:

Updated from an AMD 6850 to a 280x. My brand new 280x is not posting on my machine. I plugged in everything correct and the two little leds above the 6+8 pin light up. I have put the 280x in my brothers computer and it boots up fine.

 

My Specs:

PC Part Picker

 

MSI z68a g43 g3 with the latest BIOS update (5.2)

Intel Core i5 2500k

ASUS 280x

8gb Corsair Vengeance

OCZ Vertex 4 128gb

Antec EarthWatts 650w Bronze

 

Troubleshooting I did:

1. I tried both PCIE slots multiple times.
2. I put the 280x in my brothers computer and it posted and booted just fine.
3. I tried my brothers MSI 270x in my computer to see if it was the dual 6 pins having issues and it also booted up fine.
4. I tried my brothers Lepa 500w in my system and it did not boot.
5. Swapped in my old Sapphire 6850 (One 6 pin connector) and it posted and booted up perfectly.
6. Cleared CMOS RAM.

Conclusions:

 

• The GPU is fine because it works on my brothers system.
• The PSU is fine running single or dual 6 pins.
• 6+2 pin might be faulty, but how can both of our PSUs have the same problem?
• Something might be wrong with the motherboard or the PCIE slots.
• Or, my system isn't getting enough power. I need someone to confirm this.

I am totally out of things to try and feel like ripping my hair out. What can you guys suggest for me to try? Much respect and love to you guys for trying to help.

I think your 280x isn't getting enough power.

It's probably just a dud card, get RMA for a new one.

nvm i can't read

Have you tried clearing the CMOS?

I think your 280x isn't getting enough power.

Maybe. But it booted up on my brothers 500w system. Although he is using an amd 750k cpu. Maybe PSU really is the issue. Also, the Newegg PSU Calculator recommends 607 watts.

Have you tried clearing the CMOS?

Let me look in motherboard manual and see what that can do for me.

Update: Cleared CMOS but still nothing. I know it worked because when i turned it on, the fans stopped spinning and then started up again. Still, CMOS RAM was not the issue

Power supplies are more than just wattage. You must make sure the power supply can actually deliver on its advertisements. A cheap no-name brand PSU that advertises 700 watts will likely not be 700 watts and have crappy components and a poor soldering job compared to something like a SeaSonic unit.

I always believed Antec had quality PSUs. My brothers LEPA on the other hand is the first time I've ever seen or heard of that brand, yet, the 280x works just fine on it. I know he has a weaker system which does not draw as much power, so that might be why it works on his. Will a corsair 850w be a good choice to buy in the future?

Antec makes quality units. I'm not sure about LEPA though. However....it might actually be a compatiblity issue with the motherboard perhaps. Who made the 270X?

MSI

To me, it feels like the motherboard or card BIOS is causing the problem.

You sir have saved me! This whole time I was led to believe that my BIOS was up to date. I open MSI Live Update and it said I was on 4.20, an almost 2 year old BIOS! So I got the latest one, put it on my USB, ran the program and BOOM, my 280x has posted! Thanks a ton for replying to my posts. One suggestion. Never believe anything the original poster has posted. Always request proof (sysconfig, dxdiag, etc.) Anyways, this was one hell of a ride! This problem is officially SOLVED!

No problem. I'll try doing that.
