Sapphire R9 280 does not work with mainboard Asus P8P67-M

LeanderAT · May 6, 2015

Hello!

I bought my computer in 2011. My components:

Intel Core i5-2500K PC1155 6MB Cache 4x3,3GHz boxed
ATI Sapphire HD 6870 1024MB GDDR5 DL-DVI
be quiet! STRAIGHT POWER BQT E8-450W
ASUS P8P67-M (Rev.3.0)
8 GB Ram
Win7 64 bit
Western Digital WD10EZEX Blue 1TB SATA 6Gb/s

I wanted to upgrade my graphics card. Some gamers suggested a Sapphire R9 280. I bought it but it does not work. No bios sound. I flashed and updated my bios (2011 version -> 2013 version) but still the card does not work.

The cooling works, the light is on...but the computer does not boot. No bios sound.

What should I do?

Please help!

Your PSU is too low. You need a bigger PSU

I suggest to get this PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151095

It should work if the board's PCIe x16 slot is functional. But your PSU is too small for that card. That may be the problem if the PSU is a under-rated cheapie. Do you have both 6 pin headers populated on the card?

R9 280 power requires 25A and a 500W psu minimum. You're psu needs an upgrade for r9 280 to work.

Thanks for your reply.

I have a be quiet! with 450W. The graphics card needs 500W but a lot of people say that the manufacturers list better PSUs because of cheap ones from China that have x W but actually only output 60% of it.
My PSU is of good quality..and I was told 450 would be enough.

What is "25A"? Yes, both 6 pins are connected. The fans rotate..and the small Sapphire logo is lit...but shouldn't it be that way that the computer boots but shuts down if the PSU is not good enough? The fans work, the light works...but the computer does not boot and no Bios sound is played.

I returned the card and guess what - it was faulty. Production issues. It did not work in the computer shop either.

Got a different card now.

LeanderAT :

Good to hear. Yes, the Be Quiet! unit is very good. With its four +12V rails having a capacity of 18A each and rated for 420W, it should be... adequate for the 250W card and the rest of the system. But you are marginal. I wouldn't OC anything with it. The Straight Power (E8) has some issues: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=247
Just so you know.
