Possible power supply issues? PLEASE help

post #1 of 13
Thread Starter 
I have been having strange issues with my computer since I built it. I am new to building but have taken apart and fixed many computers. I seem to be having some sort of issue with this one I cant seem to pin-point. I think it may be power supply related. I am not very familiar with the readings that come across and what they should be at. From what I understand there should be minimal fluctuations on the 12v, 5v and 3.3v rails. From my readings anytime the computer is under load the 5v drops down to around 3v. From what my MSI control center shows 4.5v-4.9v should be the LOW warning settings for 5v and it does this as soon as I open any game or anything with occasional spikes back up to 5v. Also the Vcore seems jumpy. stays around same numbers but jumps back and forth (not sure what vcore is even really).

So I guess I should really explain what has happened thus far with the PC to lead me to knowing there is a problem. I put everything together all new parts (listed below) with the exception of one piece, the graphics card. I hadn't received my new one at the time so it initially was using a Zotac Geforce GTS250. Again at the time seemingly no issues its lightning fast, the readings were still the same in control center (5v dropping to 3ish during load). But I really didn't know at the time nor do I really know now if that's bad or not. Anyways it seems to work fine but there is an annoying hiss type noise coming from what seems to be the power supply (very faint tho not a big deal). So I used it like this for about a week or 2 before my new graphics card finally arrived (Sparkle GTX 560ti). I quickly installed it forgetting to uninstall drivers (which nowadays I don't think usually causes any issues but who knows) and when I went to turn my computer on, It instantly turned off after showing the msi boot screen for a moment. I quickly turned it back on to make sure it worked and it came up with an NVidia bios screen of some sort mentioning the bios version. Everytime I start the computer (even after using multiple driver versions) this screen still appears. Not a big deal at first the card seemed to work fine. I always play with headphones on so I didn't notice at first but a couple days later I notice theres a buzz of some sort coming from the computer while playing need for speed. It seemed to be only under load but the buzz was pretty bad. It didn't effect performance (at first) but was annoying and not coming from the fan (stopped the fan with finger and sound continued). At first I thought maybe power supply because they are so close together its hard to tell, but then the next day I have gpu-z up (which I have been monitoring off and on through-out) and the noise comes back but with no game open, then all of a sudden it gets louder and quieter (best description via text zzzZZZzzzZZZzzzZZZ) and the reading in gpu-z was usage 97% (while quieter) 99% (when louder). The noise was fast and still loud (good description is it sounded like a hard drive reading/writing large file) even when on the low end. While this was happening lines were going across the screen and the screen flashed and the start menu bar changed colors and was having major graphics issues. I restarted the computer to see what would happen. It started up and seemed to be fine but when I go into gpu-z the clock speeds were all decreasing, and gpu-z does give reason for decrease and it says utilization. but the utilization was (atleast now) sitting at 0 percent. It kept going up to normal clock then back to halfish and all the way down to like 53mhz or something. it did it for a few moments then I decided to pull the card. I am now preparing the card for RMA. So I put the old card back into the computer and the NVidia boot bios disappeared and seems to run fine on newest drivers, except there still seems to be a low buzz or hiss (possibly psu hiss increasing or maybe the graphics card really hard to tell with this one).

So with the computer seemingly too loud under load. and the power supply making a strange hiss. only reason I know this specific hiss is coming from power supply is it continues to run when I shut down my pc for almost 2 minutes. I have never seen a power supply do this before but it stays on for literally 2 minutes with the fan running and hiss continues until it shuts off. Is there something really wrong with the power supply, not the graphics card? Does it just barely run the GTS250 and was only having issues because the GTX560ti takes more power? Is that 5v rail running in safe parameters? I have tried asking many people and websites (NVidia, msi etc) for help and no one has even offered a single suggestion. Please help me I cant afford to replace parts that work. I have work to do on this computer from home and I cant afford it to not function. Any suggestions or further questions feel free to reply smile.gif

I apologize for such a long story but it keeps getting longer and I still haven't had any real answers to any of this so I have no idea what to do? Thanks for your time

Specs:
Mobo: MSI 970a-ga46 (latest bios update i think 2.1)
PSU: PC Power and Cooling 750watt Silver Certified MkII Silencer
Processor: AMD FX-8350 4.0ghz (Slightly OCd to 4.3ghz never above 50degrees)
OS: Windows 7 Pro 64bit (updated to latest updates with all .net framework installed/updated if thats relevant)
Graphics Card: Sparkle GTX 560ti (previous Zotac GTS 250)
Storage: Corsair Force Series 3 90gb SSD
Ram: G.skill Ripjaws 2x4gb ddr3 1600

Image shows 5v dropping under load quite a bit but 12v doesn't move and 3.3v only drops slightly

It really sounds to me like you do have a PSU problem. The 5v should not drop as low as you are saying this is certain and also the reason the fan is running on the PSU like that is something is too hot. I would replace this before I shipped a GPU back. You would not need 750 watts.

this ^ Can you return the problematic PSU for a refund? When shopping for a new one, make sure to stop by the marketplace on this forum, as there will be deals for good, reliable PSU's for less than they'd be new.

I used what I thought to be reputable brand. most of pc power and coolings PSU are made by Seasonic and all seemed to have great reviews. Its not covered under warranty but I may have time to return it I will try. That makes me extremely sad though It was a great deal and seemed to be a decent PSU. It for sure should not be dropping though. should I try another sensor program to make sure that's the case? I would assume control center is accurate? The psu running after computer is off it does that even if its only been on for a half a second. I don't think its heat related I think its just a "feature" to make it last longer (Really all psu should do this as a lot of the time they are still hot after shutdown and could use a moment of extra cooling). Anyways you guys think its for sure the psu though and not the GPU? Don't send the 560ti back? I literally have less then a week to figure it out otherwise I have to RMA to japan for the gpu. I don't want to be wrong haha

The hissing noise is damaged voltage regulator the damage can also be caused by voltage spikes The hissing noise is a bad sign and means the power is not stable and could harm the rest of your computer. Don't use psu anymore cos the damage could add up thumb.gif

He is exactly right!!! I did not want to get that in depth but you need a new PSU.

I appreciate it I will see if I can return it I know its not covered under warranty. So hopefully I can. Going back to seasonic and the warranty from the big guy. Hopefully my vid card still works fine and I don't have to take a loss there too frown.gif. Thanks for the quick response though I will post here again when Im up and running with something new. I might have to use this for work until then though. Kinda worrysome but it never goes under any load while working. So hopefully it will last a couple weeks without damage. thanks again for the quick response. Never asking Nvidia anything again. waited almost a week with compiling issues without even a member response. Anyways thanks again

I would not use it at all or you might end up with a lot bigger problems.... really it is not worth it...

well when your job is on the line the only real option is to hope it works. I cant afford another psu until I get PAID. I cant get paid unless I sit here and use this computer. My old computer is in pieces and unable to fix. I certainly don't want to destroy my computer, but as I said the work doesn't put it under load and it never drops voltage while not under load. Of course I don't want to hurt my computer by any means, but I don't have a temporary fix and I HAVE to work.

I have noticed though that MSI control center does not say the voltage drops, just shows the graph drop. AIDA64 shows no 5v rail information and says the 12v and 3.3v are smooth. Recommend any other monitoring that I can atleast verify the 5v is having issues? I will try to get a multimeter to do a direct test but I cant even afford that right now. I am sure theres an issue since there is a whine but what if the whine is the only issue? My old psu from my dell screeched and whined for over a year before I finally got sick of listening to it and replaced it (with no issues) and I heard this was a common "coil whine" that shouldn't damage anything so long as rails are performing well?

Anyways Im sure I will be replacing it but just to be sure that the 5v is even dropping any other hw-monitor recommendations?
