Corsair HX620 Powers system once then can't boot from power off.

Hoping you guys can help...

 

I Just bought a Corsair HX620 to replace a OCZ Modstream 450W. I needed the new P/S since the cables on the OCZ were too short for my P182 case.

 

got everything installed and the system powered up fine. I shut it down (pulled AC Line too) to install a new video card (HD2600XT) and when I tried to power up it would not start. the CPU HSF, Chipset HSF and Case fans speed up to 100% and stays there. If I pull the AC Supply and let the System sit for 30-40 min (after I drain the caps by holding down the Power Button for 10 secs) the system boots fine again! Put the old video card back in (6600GT) and it has the same behaviour.

 

the Motherboard (DFI LANPARTY see profile) has a Power Standby LED on it and when I turn off the power switch on the P/S (10 sec cycle) and turn it back on the light flashes 5-6 times then comes on solid. hit the power switch and it locks up with 4 lights on the diagnostic LEDs.

 

I initially thought that this was a power supply issue since the 450W OCZ powers it up every time. However, I pulled my Corsair 620 out of my other working computer (Core2 E6600 with EVGA 680i) and it does the same thing! :(

 

I've been extremely happy with the Corsair P/S and it is whisper quiet. But it would be nice to know if this is an issue with the new P/S or if its my motherboard in in the throes of failing...

 

I haven't had a chance to test the voltages with a meter but I'm skeptical of a failed P/S as my other Corsair exhibits the same behavior.

 

Any ideas would be appreciated. Thanks In advance...

You did set the PCI-e plug to the Video card?

THere is no ATX Power connector on this video card. the 6600GT that I have replaced didn't have one either. the system does post fine but only the first time after being powered down for a while.

I have the EXACT same issue with a Corsair VX550W... just got it last Thursday.

 

Works perfectly if I unplug the computer for ~10 minutes between power-on's. Otherwise, no boot.

 

Once running all voltages are spot-on, and it worked for my college LAN party fine this past friday... steady for 14hrs of straight gaming.

 

Also, my system was rock solid beforehand (for 8 months) with a cheap no-name PSU. I DONT want to get stuck RMA'ing this - I dont have the other PSU anymore and will be out of my computer for (probably) weeks, which is unacceptable.

 

Any help appreciated...

Cheaper power supplies will not have overcurrent/overvoltage circuits and may not be detecting if your board is going out of spec on startup. If your board is going out of spec on boot up then our PSU will shut off. I would recommend that you test the PSU on another system, however if this is not an option, we have no problem replacing the PSU for you. If a replacement causes the same issues, then I would RMA the board.

Of Course!!! that actually occured to my by reading more posts of similar problems in this forum.

 

I "solved" my problem by getting a new MoBo/CPU combo since there are no S939 boards anymore. I'll probably grab a lower spec P/S for the old one and try overclocking the snot out of it until it blows up :D:

I have also come to that conclusion... this PSU doesn't like my mobo. Since I can deal with waiting 10 minutes between boots (don't even have to unplug/reset PSU if I just wait ~10mins) I'll just stay with this setup.

 

I have one last question:

 

Since I don't have another computer to test this PSU on - and I keep it - say, 6 months down the road I build a new system and the PSU still doesn't work correctly - can I still RMA it?

 

If I still can, then I'm happy.

 

Thanks a lot. :biggrin:

Our PSUs have a 5 year warranty, so if they are faulty we can replace them within that time. Keep in mind that if your motherboard is going out of spec on the initial boot up, then all of our PSUs will behave the same way.
