skeezix Posted January 10, 2008 Share Posted January 10, 2008 Hey everyone, I built a new system: Motherboard: GIGABYTE GA-P35-DS3L LGA 775 Intel P35 ATX Intel Motherboard Processor: Intel Core 2 Duo E6750 Conroe 2.66GHz Memory: ******** 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 Video Card # 1: EVGA 512-P2-N757-TR GeForce 8600GT 512MB 128-bit GDDR3 PCI Express x16 Hard Drive # 1: Seagate Barracuda 7200.10 ST3160815AS 160GB 7200 RPM SATA 3.0Gb/s Optical Drive # 1: LITE-ON 20X DVD±R DVD Burner Power Supply: CORSAIR CMPSU-450VX ATX12V V2.2 450W Power Supply Case: Rosewill R220-P-BK Black 0.5mm SECC Steel ATX Mid Tower for a present and it worked fine for about a day. I left it on several hours at a time, restarted several times, the RAM passed memtest, etc. Then I went to turn it again and it turned on for about 3 seconds and died. It continues to do this and I can't get it to power on. I RMA'd the mobo with Gigabyte after working with their tech support to come to the conclusion that the board was the problem. The final test they had me do to clear the RAM of fault was to start the system up with just the PSU and the board. The same thing happened, after about 3 seconds or so and a beep the system shuts down. The fans spin up, including the PSU fan, but then everything just shuts down. I just received my new board from Gigabyte today and hooked everything up. The same thing happens, 3 seconds of power then shut off. Now, some other people on this forum have mentioned that their 450w VX's make a high pitched whining sound and they have been advised to get an RMA. I noticed mine does have a high pitched whine that I just wrote off before. I'm not so sure now... So my question is, since the same thing is happening, and it happens with just the mobo and the PSU hooked up, it has to be the PSU right? Even though the fans spin up a bit before shutdown? I just want to be sure before I start RMAing things like crazy to newegg or spend more money. Thanks PS Sorry for double topic, I got disconnected in the middle of posting. It's been a bad day.

utetopia Posted January 10, 2008 Share Posted January 10, 2008 It's the PSU. Corsair know about it. There are literally thousands of people with VX450W problems & a simple RMA for the same model will not fix it. An admission for Corsair to recall these PSUs shouldn't be too far away.

Corsair Employees RAM GUY Posted January 10, 2008 Corsair Employees Share Posted January 10, 2008 skeezix, if its making a whining sound, it shouldn't be and we would want to get it replaced. Please use the On Line RMA Request Form and we will be happy to replace it. I would also try the test outlined here to see if the PSU is shutting down on its own, or if something else is causing it to shut down. utetopia, there should be no problem using the vx450 with skeezix's system, and where are you getting this "literally thousands of people" having problems with our PSUs? With any type of electronic device there is going to be a failure rate, and I can assure you that our failure rate is below the industry average. Should someone end up with a faulty PSU we will certainly replace it. Keep in mind that this is a support forum, and the thousands of people who purchase our PSUs every week who do not have any issues are unlikely to post here to tell us about it.

skeezix Posted January 10, 2008 Author Share Posted January 10, 2008 Ok I tried the test with a hard drive because I don't have a fan that can hook up to the PSU directly, if I'm understanding the test right anyways. Nothing happened when I shorted the pins with the paperclip. But I don't fully understand the point of the test, the fans spin up when the system powers on but then stop once the system promptly shuts down. It seems to me that if I had a fan to do the test with, it would probably work but not solve my problem. Shall I try anything else before I go for the RMA?

Corsair Employees RAM GUY Posted January 10, 2008 Corsair Employees Share Posted January 10, 2008 Shorting the green wire with any of the black wires should start up the PSU and the fan on the PSU should begin spinning. If the PSU stays powered and does not shut down (like you explained was happening when connected to the motherboard) then there could be an issue with the motherboard telling the PSU to turn off for some reason. Could be faulty PSU, CPU, motherboard etc. The only way to know for sure would be to test the unit in a different system, but if this is not a possibility and you would just like to replace the PSU, then please use the On Line RMA Request Form and we will be happy to replace it.

skeezix Posted January 10, 2008 Author Share Posted January 10, 2008 Thanks a lot RAM GUY and Corsair for offering to replace it hassle free. However, I wasn't convinced it was the PSU based on previous bad PSU experiences (thank you Dell), so I tried it the 450VX in another system and it booted fine, I didn't notice the whine this time either. But...now what do I do? Was I just very unlucky and got a dead replacement board? Could something else be the cause? I was told processors rarely go bad, and because mine was working fine for a day I'm inclined to think it's ok. :confused: I suppose I could swap out the RAM maybe. Hmm EDIT: My friend said this doesn't rule out the PSU as the problem stating the other system's board could be less sensitive to power. He recommended trying a different PSU in the new system but the only one I have is a 350W in my Dell (also the one I tested the 450 VX on) so I doubt it would work anyway. He says I may be getting a brown out. Any thoughts? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 11, 2008 Corsair Employees Share Posted January 11, 2008 Reset CMOS and test the system with one memory module at a time. If the PSU is working in a different system, it is unlikely that the PSU is faulty. If you do not hear the PSU "whine" in the Dell sysetm it is likely that the noise was being made by a coil on the mobo, probably near the PSU. I would suggest testing a different PSU in your system if that is an option, and see if you get the same results. Link to comment Share on other sites More sharing options...
skeezix Posted January 11, 2008 Author Share Posted January 11, 2008 Ok. So. I went out and bought an Antec 500W Earthwatts PSU, same result. I retested the RAM sticks one at a time. I've cleared CMOS before with the same result. I swapped out video cards and no luck. The only thing left is the processor or a possible bad motherboard. Given that the board is a new one, and it did the same thing as the old board immediately rather than after a day, I'm concluding the processor is to blame because something obviously went bad. Thanks RAM GUY for your help despite the problem being something else (I hope). When I find out what the problem is I'll update this thread for closure.

EliteKiller Posted January 11, 2008 Share Posted January 11, 2008 Disconnect everything (including the cpu) from the motherboard, remove it from the case, and set it on a cardboard box. Now reinstall the cpu and hook up the 24-pin & 4-pin 12V ATX connector only. Now try to hook up the front panel power switch, or use a paperclip/screwdriver/etc. to short the power switch pins on the mobo to initiate power on. Even though it will not post it should still power on. If not you've narrowed it down to the board or cpu. Link to comment Share on other sites More sharing options...
inertiaticesp Posted January 26, 2008 Share Posted January 26, 2008 I have the same motherboard and my vx450 was also making that exact same whining/electrical buzzing sound plus there was a slight smell in the room after the first power-up (i think the smell comes ocassionally, not sure). It seemed to go away when the system was under load but would return if I started a program or browsed the HD (synched with double clicking). At first I thought it could be my videocard because the noise goes away when it isn't there, but can't be entirely sure because there's no screen and I can't exactly recreate the situation as if I had card in. Besides the sound, there is absolutely nothing wrong with anything. My computer's new with parts from Newegg so I RMA-d it, hopefully the new one will be better. Another thing, I just finished reading a couple of reviews on some of the parts and the motherboard seems to have trouble with some ram at stock settings (1.8v), in my case it's a gskill 2GB. They have fixed it by upping the ram voltage by 0.1 or 1.9 and I was just wondering if that might have anything to do with the PSU making whining noises. I'll report back in a few days after Newegg sends me the replacement PSU and will hopefully have more answers for others with the same problem. EDIT: PS: I also pulled the PSU out to listen and I'm fairly sure it's coming from there. Link to comment Share on other sites More sharing options...
