Psu turns off ?

[Hughes123]

i currently have my mobo outside my case running, i use a jumper to start it, but if i keep my 6 pin pci-e in the gpu it wont turn on, if i take it out it will boot but the gpu needs the 6. my psu is a corsair 430w so it has enough power. also i use a 2xmolex to 6pin pcie adapter

Faulty card or you do not have enough power. Post your full specs!

 

[scout_03]

give the name and model of that psu since most of the corsair 430 have a 6 pins pci-e connector .

I have tried the card on another system, works fine. i have also tested the psu and all the wires are working. my idea might be that the adapter for 6 pin might need a molex each from separate molex cables

gigabyte am3 mobo (not sure which model)
phenom x4
asus directCU2 6950
4gb kingston 1333 ddr3
corsair cx430m
usb boot up (no hdd or any other peripherals)

Check if there is a bios update for your board, many gigabyte boards need it for ver 3.0 cards or run BIOS in legacy mode.

I dont think that will be the problem because i ran a xfx 7950 with a different psu on it for a while and that worked fine. could running 1 molex from 1 line and running the other from a different molex line help. because the lines will be empty apart from that so it will both have separate power from each line to go into the 6pin pci-e

 

[scout_03]

this is your psu and it have a 6 pins pci-e cable so you dont need the molex adaptor check all the cable you have on hand .http://www.corsair.com/en/cx-series-cx430m-modular-atx-power-supply-430-watt-80-plus-bronze-certified-modular-psu.html

I had a look in the box but there is no 6 pin. only one 6+2 pin came with it, and also 1 molex line, and 2 sata power lines

 

[scout_03]

the 6+2 could be the pci-e cable .

 

[Hughes123]

Im already using the 6+2 in the 6950, but i still need another 6 pin

Only using 12 volts from a single rail PSU should not matter.

I thought that. but every time i plug the 6 pin adapter in the system just shut off again ?

 

[Hughes123]

since the psu still has a spare 6 pin slot for a modular cable, would this work, http://www.scan.co.uk/products/silverstone-sst-pp07-ide6bg-pcie-6pin-to-pcie-6pin-250mm-black-gold

 

[scout_03]

it will not since you already have another gpu on the psu it could not handle both card lack of power that why it cut to protect itself you need to get a bigger psu that will support all the parts in the computer .

so there's no way of powering it? i only bought this 2 days ago and i have no money left for a bigger one

i only have the one gpu on it, is there any way i could use any adapter to power it. i still have 2x6 pin sata&peripheral modular slots left.

 

[scout_03]

the power specs you gpu need so i dont think that psu could handle it . http://www.asus.com/Graphics_Cards/EAH6950_DCII2DI4S2GD5/#specifications

So this psu has no chance of even getting it to power on ?

 

[scout_03]

no it wont even on amd they say it need al least a 500 wattts psu or higher with 2 x6 pins power cable .

Ok thanks for your help. now im stuck with a power supply that is no good and a system i can't power 🙁

 

[scout_03]

does your motherboard have a onboard video chipset or try to find a older gpu card around to use the system until you could get a bigger psu and try to return this one if you could for the shut off issue .

 

[rolli59]

Agree with the above the PSU is struggling with the card although a system with a HD6950 here pulls only 326 watts total load. http://www.anandtech.com/show/5625/amd-radeon-hd-7870-ghz-edition-radeon-hd-7850-review-rounding-out-southern-islands/17
Maybe your specific PSU can not provide the full 32 amps (384watts) on the +12 volts it has but it is really cutting it close to have the CX430 running that rig.

 

[Hughes123]

would a cx500m be enough ? i just about have money left enough for that

 

[rolli59]

Yes it would
