does the seasonic 750w not work with gigabyte ud5

ants83 · 1 Aug 2009 at 14:09

i have an i7 system, the seasonic md12 750w does not work with the gigabyte ud5 mobo. It powers on for 2 secs then stops, i take it there is no way around this? anybody manage to get a similar system working?

make sure you plugged everything in

try clearing cmos as well

ants83 · 1 Aug 2009 at 14:28

cmos cleared, everything is plugged in. i have tried to boot it up at stock ie no overclock but still nothing?

You're getting power for a split second then nothing? Have you checked to see if its shorting? Have you tested the PSU to make sure its not hosed?

Drake22 · 1 Aug 2009 at 14:38

mm could be faulty psu or not enough power, try taking out components one by one, start with graphics card

ants83 · 1 Aug 2009 at 14:41

i have tried it with just the mobo, then with gfx and mobo and all it does it boot for 2 seconds ie fans spin up then it dies. i test it with another psu and its fine. i mean is it possible for a psu not to work with a certain type of motherboard?

Try just one stick of ram, unlikely to be PSU.

Drake22 · 1 Aug 2009 at 14:48

ooo btw, is ram in blue or white slots? are there any codes on motherboard?

Take the board out of the case and seat it on a bit of cardboard and try it that way, and no, they will be compatible, that's what standards are for. There's something up and it sounds like a short, a busted/loose component or a busted psu.

Ive had exactly the same problem with the 850w. I RMAd the first and the 2nd did the same thing.

The PSU works in every other system I've tried it in. And every other PSU I've tried works with the Gigabyte.

Ive ended up swapping it with a PSU in another system to avoid a 2nd RMA.

right so basically i have no chance of this working? i wonder why this it? i mean i have got it to boot but after i shut it down i get them same 2 second boot up error.

just make sure ur ram is plugged in white slots

if its in blue, try swapping; if not, then its karma

Oh thats interesting, I just RMA'd an 850W because I had exactly the same issue with a Gigabyte UD5. I'll phone them up on monday and point them at this thread.

Yeah sounds like an iffy psu tbh

Yeah I had that too. First time I installed the 2nd PSU it booted up fine and I thought all was ok. I shut down it down and after that rarely ever got the thing to boot again. I had the fans cut out anywhere between 1/4 of a second to 2 seconds after power on.

I have no idea what is up with it, but it works perfectly well in my 2nd system that I built for my missus (not an i7 with Gigabyte UD5 mobo), so I cut my losses and just switched the PSUs over. I couldnt be bothered with paying to send it back again. Plus the small case I have means to remove the PSU I have to remove the entire mobo and HDDs etc. It was wearing a little thin with me....

H'mm must be just that board or something very very strange.

I've got the Gigabyte MA790FXT-UD5P (AM3) motherboard works fine with that.

PlumpMonkey · 1 Aug 2009 at 16:25

It is the Gigabyte GA-EX58-UD5 board that I have from the overclocked bundle. But I had the same issue at default bios settings too so its not an overclock issue

ants83 · 1 Aug 2009 at 16:27

just flashed the mobo with a beta f8f i think it was and still no luck. It did boot then after a shutdown it doesnt want to no. RMA i guess then, shame i liked the look of this psu

thats the one and no its not an overclock issue

Silly question but have you tried waiting a few extra seconds? I seem to remember when I used my Biostar X58 I had to wait a good 10 seconds before pressing the power button otherwise it woudnt boot up.
