I've recently built a computer and whenever I boot up, a message is displayed saying: "The Nvidia system sentinel is reporting that Nvidia-powered graphics card is not receiving sufficient power.

To protect hardware from potential damage or causing a potential system lockup, the graphics processor has lowered its performance to a level that allows continued safe operations."

I have the 6 pin Power connecter conncted properly, I have a 585 Watt dual rail PSU It's also a MSI 9600 GT videocard, its the overclocked version.

System specs

Processor: amd athlon 64 x2 4800+
Ram: 2GB of DDR2 PC6400
OS: Windows XP pro.
VideoCard: MSI 9600 GT http://www.newegg.com/Product/Product.aspx?Item=N82E168...
PowerSupply: Hec orion XPOWER 585Watt dual rail 12v http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Is my power supply good enough???




NOTE: when the first time I ever booted up windows it did not do this, only after I got the latest driver. (I've only had this computer for 2 hours now)

That power supply is more than enough. I say roll back the driver and submit and trouble ticket to NVIDIA.

If you aren't noticing any problems with an older driver then I would suspect a problem with the new driver.

I have a 500w power supply (Antec Earthwatts) and a 9800gt, I do not get an error like this.

It's a poor quality PSU, but should certainly have enough power for that system.

Turn the computer off and unplug it from the wall. Then reconnect all the power connections and re-seat the video card.

A psu may have enough watts for the system but it may not carry enough amps on the 12v rails; especially split rails psu's with limiters. Cheaper psu's with more than one 12v rail use limiters to mitigate any chance of overloading and frying the psu.

Honestly, dump that psu and go snag a Corsair CMPSU-550VX as it's got a single 12v rail with 41a capacity. Compare that to the Orion psu with a 19a/20a limit on each rail.

Never cheap out on the psu!!!!

As a rule of thumb never get a psu with anything less than 30a on the 12v rail if it's a single rail. And if it's a dual rail, do some research to determine if there are limiters on the 12v rail or if the amps are shared across both rails.

and dont buy the cheapest psu on the continent either. $25 for a device that could fry everything else on a system isn't a very smart move...

Corsair HX620w, because overkill is a GOOD thing. :lol:

I went ahead and bought a 550watt power supply, its single rail. here's the link (I only have $30 so I had to get this one =/) best rating for the price.

This is good for my 9600 GT right? http://www.newegg.com/Product/Product.aspx?Item=N82E168...

The quality of that is equal to or worse than your HEC.

Lol....oh man...

Very few PC parts have their quality determined by brand, but the PSU is one thing where brand DOES matter. Cheap PSU = nightmare in the making. Numbers are not everything, for example Corsairs 1000W PSU can output more and handle more stable load than a 1200W by a cheap brand. Or Corsairs $60 400W PSU is about on par with a 500+W cheap brand for $30.

Looks like somebody is sad. -1's for all!
February 14, 2009 7:37:23 PM

So this PSU will not work?
February 14, 2009 7:38:07 PM

I mean if you already bought it its too late, at least try it.
February 14, 2009 8:08:09 PM

Wonder if the OP tried any trouble shooting before he ordered a new power supply. There are many times when just throwing new parts at a problem wont fix it.

Could be a faulty video card ya know. You would have been better served by knowing the problem before jumping ahead to newegg....
February 14, 2009 8:57:56 PM

I did search alot and found out that since my PSU is 2 12v rails at 19 amps and 20 amps, and I need 26 amps for my videocard it will not work. I also read my PSU does not combine the amps.
February 14, 2009 9:01:12 PM

26amps for a 9600GT? Uhhh
February 14, 2009 9:11:35 PM

Is 26 amps alot? says on the box that's what it needs lol.

The 26A requirement is for the entire system and they overestimate the requirements because of crappy PSUs such as HEC and Logisys.

The Logisys only has 25A on the 12V, the HEC probably more (but they don't list it).
February 14, 2009 9:45:55 PM

so then the PSU is not the problem, what is the problem?

The number of rails does not matter. Quality does.

/TILT/
As a general rule, a PSU that has Active PFC and is 80+ certified won't be crap; at worst it won't be quite up to its labeled rating. At best, it will be a Corsair, Antec, PC Power & Cooling, or similar high-quality unit.
I suggest you return the Logisys, eating the restocking fee as the fair price of the lesson. It is probably too lightweight to even be a good doorstop. The HEC should be up to the task; it may be low-quality also, but as others have pointed out, what you've described sounds more like a driver problem.
Does your mobo have a molex power connector on it too? I've seen them on some AMD boards, typically to provide additional power for the PCI Express slots. You shouldn't need it, but plug it in anyway if present.
It is possible the +12v rail on that HEC is low. Does your BIOS tell you what it is? If not, get Speedfan, I believe it does.
February 15, 2009 1:17:52 PM

Not sure what you mean by my motherboard having a molex connector, I don't think it does. and I checked the bios I don't think it tells about my power supply, will download speed fan.

Thanks.
February 15, 2009 1:39:23 PM

Most BIOS will tell you in the power management tab. Youll see listings for 12v+, 5v, and 3.3v. All of those amounts should be at least said amount, if any of them dip below said amounts the PSU is unsatisfactory.
February 15, 2009 2:11:30 PM

Even if the BIOS or Speedfan says that the voltages are OK, they may not be. The only way to be sure is to use a DMM.
February 15, 2009 2:23:59 PM

Good post over there animal.
February 15, 2009 2:28:24 PM

I downloaded speed fan and it says

Vcore1: 1.34v
Vcore2: 1.89v
+3.3v: 3.36v
+5V: 5.13V
+12V: 12.10V

I have this battery checker thing that tells me the voltage of a battery, is that a DMM lol? and how do I use it?
February 15, 2009 2:35:53 PM

Oh btw, I haven't tried the new PSU I ordered because it will not arrive untill wednesday or thursday. I did try unplugging my 120mm fan and my 80mm fan and seeing if that fixed the power issue, and it didn't.

I've also unplugged the GFX card and reseated it, tried two different adapters for the 6 pin PCI-E plug, I switched my HD and CD-Rom and my fan's all to one cord, and left the 9600 GT on the other alone. nothing worked.

I tried the driver that came with the videocard, that didn't work either.

I geuss im doomed, let's hope the new PSU works....
February 15, 2009 2:43:15 PM

Wait....youre using an adapter to change molex to PCIe? That's more than likely the issue. You need a PSU with a dedicated PCIe plug.
February 15, 2009 2:43:56 PM

Yeah my PSU came with one, it doesn't have a dedicated PCIe cord, just a molex to 6 pin.
February 15, 2009 2:44:40 PM

I also read a newegg review that this guy had the same problem as me with his 8800GT, he said the rails screw everything up.
February 15, 2009 2:47:46 PM

but I looked at the new PSU that everyone says sucks and I hope it doesn't because I don't want to take it back again, it has 2 dedicated 6 pin PCI-e cords, hope it works!

Is the new PSU the Logisys???

doom...doom...Doom...DOOM...DOOM...Doom...doom...doom...
February 15, 2009 2:56:30 PM

lol.
February 15, 2009 2:56:55 PM

it got good reviews.
February 15, 2009 3:08:14 PM

You should be fine with the Logisys one despite what was said above. Using those molex adapters is bad news.
February 15, 2009 3:09:55 PM

Yeah im reading alot of reviews on it and some people are powering 2 9800GTX with this PSU and he has had it for 2 years. im more happy now that im reading alot of good reviews.
February 15, 2009 3:52:57 PM

I think im a retarded idiot, my PCI-e adapter has 2 molex and then on the other end the 6 pin for the videocard, do I attach both molex and then straight to the videocard?? I didn't do this before! I just attached one molex, I thought the other one was for like if you wanna hook a second HD or Cd-rom fan etc. HELP

February 15, 2009 4:35:56 PM

You need both, typically attached to different cables off the PSU.
February 15, 2009 4:36:49 PM

AAH, I tried connecting both and still power issue, I was sure that was the problem! ugh!
April 5, 2009 11:43:55 AM

any news on this one, iv got a winfast a350 128mb agp gpu and i get the power low message and i ca't even do a proper stress test, my pc crashed and i get the blue screen, i have a 600 watt psu(win-power, yes i know a crap brand)

anyone any ideas?

The PSU you bought, the $30 Logisys, may not be up to the job, no matter how may watts it claims. I think you'll just need to bite the bullet and get a quality PSU. The Antec Earthwatts 430 is only $55 now.
Ugy, I suspect you will get more useful answers more specific to your case if you start your own thread.
