What power supply do you have in this rig? sounds too low end.

| Most of that info came from my own experiences when I first put a nVidia | Geforce 6800 GPU (requiring 1 additional PSU connection) in my PC, it | would often power down for no reason whatsoever, and then trying to find | out why _____ Well, a few anecdotes don't a summer make. 1. ATX specification power supplies (ATX12V and later) don't operate in the manner you seem to have understood. They have 'load sharing' - wattage is shared among the important rails, +12V, +5V, and +3.3V. 2. A display adapter using the nVidia 6800 uses far less power (perhaps half) compared to one using the nVidia 6800 Ultra. 3. New GPUs aren't 'requiring their own power'; some display adapter have several connecting pins for +12V DC; this connects to the same +12V DC rail that drives use. This replaces power that was previously drawn from the +5V DC and/or +3.3V DC rails. The display adapters have on-board DC-to-DC down-convertor/regulators that work more efficiently with +12V DC input than with +5V DC or +3.3V DC input. The connecting wires and traces can be smaller. The higher input voltage provides more stable operation. There is power wasted and less heat produced using +12V DC than with the lower voltages. Just because a display adapter requires a +12V DC connector doesn't mean it draws more power than one which does not - it may even draw less for the reasons just given. Using multiple +12V DC connectors SAVES power because less in wasted in contact and conductor resistance. 4. Multiple USB devices ~= multiple fans ~= negligible. Multiple drives ~= not very much except during spin-up. ATX power supplies DO NOT SHUT THEMSELVES DOWN IF TOO MUCH POWER IS DRAWN! ATX power supplies DO shut down if a dead short develops. ATX power supplies will begin to overheat if to much power is drawn, but this takes a relatively long period of time, much longer than the period of time for drives to spin up. The overload protection fuse is to protect the AC wiring with in the case and the AC wiring between the case and the building breaker box. This fuse is a safety feature, not an overload protector. An overload of several times the rated power is necessary to blow the fuse within a few minutes. 5. | I replaced my system with a | 500w power system but it would also suffer power downs for no apparent | reason. I was advised that my system did not draw enough power and the | PSU was invoking power-over management and reducing power output to | avoid a 'burn'.

Power supplies are rated at a specific temperatures. At higher temperatures they must be derated. A power supply that is more than adequate at 60 C can be inadequate at 75 C. 7. | I was advised by others not to put in a 500w PSU as I first wanted to | do. Yes PSUs have under-draw protection, but prolonged use at low power | levels supposedly reduces the lifetime of the PSU. You were advised wrongly.

If it's a cheapie PS,it doesn't matter if it's 800W!! Not saying you've got
a crappy PS. But if it doesn't have enough amperage on the 12V(18A at least) and 5V(35A at least) you might get problems with new hardware and software.. It could be Far cry stresses everthing and shows some weaknesess. I could be wrong. Might be a software problem with motherboard drivers or even sound drivers. "AAvK" wrote in message news:VXo1f.630$UF4.88@fed1read02... It's probably related to your power supply. You are probably using too much power for it to handle. anything less than 350 watt power supply and you are asking for trouble. If you have alot drives etc then a 450 watt PSU would be the go. Thanks but that's what I've got, 450 watts and it is plugged into the card. No other game besides Far Cry shuts the computer down. -- Giant_Alex cravdraa_at-yahoo_dot-com |

You say this is sufficient, I have enough cooling definitely as the whole case is internally exposed... the side cover is off. Only Far Cry shuts the computer down, doesn't matter if anything is drawing too much power, so the PSu must have some kind of short? I did find a small capacitor on the floor of the case one time over a year ago. I examined the whole mobo and the cards, no place could be found where it would be missing from. Do you think the cap could have lopped out of the PSu through the fan??? This PSu has a fan on it's bottom face and another on the face that is the back, where the power switch and cord are located. -- Giant_Alex cravdraa_at-yahoo_dot-com |

To top thing off I | reason enjoy the reduction in noise. _____ What I've found to be very useful is to arrange for the CPU heatsink fan to blow down into the heatsink, then cutting a 120mm hole in the Tower case side and mounting a 120mm fan to blow outside air directly into the motherboard area that contains the CPU heatskink/fan, DC-DC voltage convertors/regulators, memory, chipsets, and the back of the display adapter. Two 80mm fans blow blow out the back. The power supply has two fans that exhaust through the rear. All air intake is through the front across the hard drives and removable media drives. With this arrangement the temperatures go UP when the side is removed. The cases I like best (if bulky isn't a problem) is a tower that is deeper than is usual, the EN-8950. This Enlight case is convertible to use either as a tower or a rack-mount case, and has the dimensions of 25.6" inches high by 8.6" wide by 19" deep, deep enough for the drives to be nearly a foot from the motherboard. There are 9 slots with rails for 1 inch hight hard drives and/or removable media drives that can be removed and isntalled through the front door. It isn't fancy, but the extra room inside promotes good air ciruclation and makes component changes easier. It comes with or without power supplies (including redundant supplies, up to 2 X 600 Watts) as well as a hot swap module for 5 X 1" height drives. Electrostatic filters are provided for front intake and rear exhaust. The price is bad, ~ $100 US last time I bought (no power supplies or hotswap module included at that price.) The one I have up and running at the moment has 5 hard drives, a floppy, a DVD +R/W, a CD R/W, and a zip drive, leaving one slot free. The system is a 'Northwood 2.6' GHz @ 3.510 GHz with 640 MBytes RDRAM and the display adapter varies. As you experiment with air flow, you might want to invest in a small digital indoor/outdoor thermometer with a probe. A store like RadioShack will have one for ~ $15 US. _____ Phil Weldon "Al Kaufmann" wrote in message ... | On Sat, 08 Oct 2005 05:41:59 GMT, "Phil Weldon" | wrote: | | 'Al Kaufmann' wrote, in part: | _____ | | | I bought the Antec TruePower supply and I knew that the power supply | | fans run at the lowest speed appropriate to load and conditions.

| Phil, power I am using, 375 watts plus 20% adds up to exactly the same as my | PSu is rated, 450 watts. _____ Looking back over your posts, it sounds like a heat problem, but where? If the power supply is involved, then poor air circulation is possibly the culprit, otherwise the power supply might just be poorly built. Certainly 450 Watts is more than sufficient. One easy diagnostic tool is MotherBoard Monitor 5. It is a free utility and very well respected, available at http://www.3degs.net/ . It will log and display three or more temperature sensors as well as fan speeds and voltages. Install this utility and log the reports as you operate your system at various crunching levels. The log should give you an idea of what's going on. Also use an indoor/outdoor digital thermometer with a probe to check air temperature inside the case and especially the temperature of the air leaving the CPU case. Removing the side from the case may make some areas hotter and some areas cooler. Check the PSU intake air temperature and output air temperature. It may be that the power supply is getting air that has already been heated by the rest of the system. Also, before buying a new power supply, try removing the power supply from the case, but keep the cables plugged in. This should determine if poor air circulation is the cause of your reported problem. You say you found a capacitor in the bottom of the case. There are so many capacitors on the motherboard it would be hard to determine if one were completely missing. I think it highly unlikely that a capacitor could have escaped from the PSU box. A description of the capacitor you found would help. If it is a tubular electrolytic capacitor, about the size of a 1 inch length of pencil, with a value of 10,000 microfarads or so and a working voltage of 20 Volts or so, and it fell off the motherboard or Display adapter, then it likely is from one of the capcitors in a DC-DC regulator/convertor, and that is a serious problem that likely will make the DC voltage it supplies sag under high current draws. If it is smaller, say a 1/2" length of pencil, with a capacitance of ~ 100 to 1000 microfarads, and with a working voltage of ~ 7 Volts, then it likely helped eliminated noise on the power traces on the motherboard or a card. But those are just guesses. By the way, I have a system with a 450 Watt power supply 'Northwood' 2.6 GHz @ 3.51 GHz 640 MBytes of RDRAM 5 hard drives 1 DVD +R/W 1 CD R/W 1 SCSI Zip drive 1 3.5" floppy SCSI PCI card Sound Blaster Audigy 1 wireless LAN 1 USB2.0 PCI card 1 Television Tuner/Capture card 1 AGP slot with varying contents, usually about a 40 Watt card Worked fine with a 350 Watt supply, works fine with a 450 Watt supply. However, I don't play games demand a lot of GPU power. I do run high CPU usage applications. Good luck. Please post as you gather more information. The shortest, easiest path to identifying your problem might be to #1. remove the case side and place a 20" box fan blowing directly into the system case and try to recreate the problem #2. swap in another known good Power Supply and try to recreate the problem #3. then swap in a known good identical graphics card and try to recreate the problem Oil squeaky wheel.
