reybeez Posted November 16, 2006 Share Posted November 16, 2006 I just bought the HX620 because it's sleekness and support for future upgrades. I plugged it in it indicates that there's power to the motherboard yet when I press the power button, everything lights up for 1 second then shuts down. I tested the PSU by itself (that paperclip bit) and it seems to be working (the fan turns on) but I don't know what's going on. Is my motherboard incompatible?

Corsair Employees jonnyguru Posted November 16, 2006 Corsair Employees Share Posted November 16, 2006 Wouldn't surprise me. A7N8X eats power supplies for breakfast. It has a high 5V load, virtually no 12V load and doesn't support ATX12V specifications. About two years ago when that board was new, I worked for a reseller that sold them and built with them. Never saw motherboard and PSU RMA's that high in my life. Get an old school ATX (not ATX12V) PSU if you really need to replace your old one, or get an ATX12V motherboard for your Socket A chip.

CandyKid Posted November 17, 2006 Share Posted November 17, 2006 I've built a few systems with the A7N8X-D motherboard and never had a problem with them! It was the A7V8X that always gave me troubles! You might want to check out your stand-off's to see if you've got a short in the system as that would cause your particular problem (protection circuit). If possible, run the system with the motherboard outside the case on a piece of cardboard. (FYI, static-proof bags are only static-proof on the inside. They're conductive on the outside so don't sit your board on one of those.) PLUR CK Link to comment Share on other sites More sharing options...

It was the A7V8X that always gave me troubles! The A7V8X gave me a lot of memory problems. But the A7N8X has given me PSU problems. The ones you built: What PSU did you use an ATX PSU or one with independent voltage regulation? And if you used a "modern" ATX12V PSU in it, do you have access to one to check out how high your 12V rail is?

Although I have to admit that I didn't take this path because I was under the impression the build was already up and running and that the only thing that changed was the PSU.

Yeah, the build was already running. The only thing changed was the PSU. Link to comment Share on other sites More sharing options...
CandyKid Posted November 17, 2006 Share Posted November 17, 2006 To be honest, the reason I suggested running outside the case is it's the easier of the solutions that I can think of. The other source of a related issue I've seen is a dead chipset and that's not any fun! As for the builds I can remember, they were: 2800+, Antec TruePower 430 ATX12V 3000+/333, RaidMax 400 ATX 3000+/400, OEM 400 ATX (if any PSU was going to die, I'd expect this one) Never externally checked the amperage, but rails were all stable. The third one of these also included an ATi 9800 PRO among other fairly power-hungry hardware as well. PLUR CK Link to comment Share on other sites More sharing options...

PLUR CK As far as I know, all of those PSU's have only a single +12V rail -- no +12V1 or +12V2 or +12V3. And all of those PSU's have more capacity on their +5V rail than modern PSU's with multiple +12V rails do. Thus, I can deduct that the problems are caused by insufficient +5V capacity for the OP's system, especially since none of Asus's Socket A motherboards have a square 4-pin ATX+12V P4-style connector.

Firage Posted November 24, 2006 Share Posted November 24, 2006 I've been running a build with the ASUS A7N8X-E mobo and the HX620W PSU for 2 days straight, and everything has been going smoothly so far. I don't have an accurate method for measuring my voltages, but the BIOS readings have shown less than 3% of variance. Link to comment Share on other sites More sharing options...

PLUR CK For what it's worth, I've built 2 machines with the first build (2800+, Antec TruePower 430 ATX12V) and with this motherboard, I've had to RMA 3 power supplies. Antec told me that there was a batch of power supplies with a problem with this motherboard. On machine A, the power supplies lasted about a year apiece. On machine B, it lasted only 4 months. On machine A (my machine) it died the second time last week, and I'm going to replace with a Thermaltake instead. Link to comment Share on other sites More sharing options...
CandyKid Posted December 11, 2006 Share Posted December 11, 2006 Wierd. That's a bit odd, but sure seems like a pattern. I'd get something a bit beefier that won't have a problem with the extra 5v drain or whatever it is. PLUR CK Link to comment Share on other sites More sharing options...
reybeez Posted January 4, 2007 Author Share Posted January 4, 2007 So are there any official solutions for this? Is there a list somewhere that marks my motherboard as incompatible with this product. There's no way that I can update the bios now and am being forced to buy a second power supply or upgrade my motherboard. Link to comment Share on other sites More sharing options...
Wired Posted January 5, 2007 Share Posted January 5, 2007 Corsair never said it was incompatible. I'll notify them of this thread, most likely it'll simply be RMA'd. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 5, 2007 Corsair Employees Share Posted January 5, 2007 There should not be any problems with this MB and our PSU's that I am aware of. Was the system working with another PSU and have you connected all of the other accessories like your HDD's and CD/DVD's? Also does your Video card take external power if so please make sure its connected properly. Link to comment Share on other sites More sharing options...
reybeez Posted January 6, 2007 Author Share Posted January 6, 2007 Yeah, it was working with the old PSU. With this PSU it powered the mobo (LED was green) but upon power press it'd spin fans up for 2 seconds then shut down. Update: I got it to work. Solution: I pulled out the battery on the motherboard, waited 5 minutes then put it back in. This time when I turned on the compy it didn't immediately power down but kept going. So I turned it off, plugged in all the drives, cards and hd's, turned it on again and it booted up just fine. Link to comment Share on other sites More sharing options...
