Did I under power this? No post after 2 weeks.

Boared · Jun 12, 2014

Hi,
My build
( I never even used the new display, just a temporary 17" one.) After 2 weeks I couldn't pass post. No beep, just fans spinning for 2 seconds, pausing, 2 seconds, pausing ...
I rma'd the PSU and when I couldn't post with the replacement, either, I called and the tech felt my PSU wasn't powerful enough. I'm now waiting to be approved to rma the board, in the meantime should I buy a more powerful PSU?
I stream financial market data through moderate dsl, and will be watching movies.
Thanks.

What system do you have? And what PSU did you have?

Can't really go far w/o that information.

The CPU+GPU would come to around 250W. Add on an extra 100W for the rest of the system and you're at 350W, well under the 450W PSU...

The wattage is the right amount, maybe the PSU failed.

Thanks, I thought so as well.
But I replaced the first PSU with a new PSU and the symptoms remained. It doesn't seem they actually tested my first one, they just sent me a new one. The tech did an internet search and seemed to think my card required too many amps for the 37 supplied by the psu. I see two reviews of my card, the highest shows that it can reach 108 watts. Divided by 12 that would only require 9 amps. My chip shows an 80 watt max draw, that would correspond to 6.7 amps.
I'm waiting to see if Gigabyte will approve me to send them back my board to verify or replace. I presume after not working with 2 PSUs, it's the board or chip. The only change came when I cleared the CMOS battery. The fans now spin and pause for longer than before, but I still can't get beyond 2 seconds before the power cycles.

Well you have a point, but the problem you have is really common among failed PSUs.

Until Gigabyte responds you might want to try the steps on this guide and see if you can fix your problem:

I went through that sticky with the original PSU. Nothing changed with any step. I also bought a new chip fan, just in case. And the symptoms are exactly the same with new PSU. It seems they don't test exchanges in the first 30 days, they just accept them and replace them, so it's possible both PSUs are fine and exhibiting symptoms, but are not the underlying cause. I was just worried when the tech told me my amp draw was too much and even with this one possibly fine, I should still get a new one.

I spoke with another tech that agrees this card won't draw too much power. He also added that as it only gets power through the pcie slot, with no direct cable from the PSU, it will only draw the amount the board allows. We assume, perhaps, the other tech was looking at the amps and watts of another card, the names are very similar on many of them. That being said, I'm still waiting to hear back anything from Gigabyte. I will update any pertinent information.
Thanks.

I still haven't heard a peep from Gigabyte. I just tried to email them something. I went back to pcpartpicker and removed the board I had put there in a rush yesterday:
Gigabyte GA-B85M-D3H
with the one I actually have and used for two weeks:
Gigabyte GA-B85M-DS3H
and they flag it as incompatible with my chip. Gigabyte lists the chip as suitable for the board. I wonder which site is more reliable, Gigabyte or pcpartpicker.

Boared · Jun 16, 2014

PCPartPicker got back to me before Gigabyte did. They figured it was an oversight after confirming that Gigabyte does list the parts as compatible. Gigabyte issued an RMA, I removed my chip to pack and send the board away and decided one of the pins in the socket seemed slightly out of line. I nudged it with a piece of paper, very gently, and can now boot. Thanks.

Awesome. Glad that the problem is solved
