I just received three video cards for a 3-way SLI rig - however my current power supply does not have enough PCI-e connectors necessary to fully power all three video cards. The cards didn't come with any molex-to-pcie adapters.
Can I use a spare power supply to power the third video card? My spare has the connectors I need. Would I need to somehow switch the spare ATX power supply to on mode, perhaps with a piece of wire on two pins on the rail, the switch in the back, or some other method? Or will the card draw the electricity on its own? Do I run a risk of damaging the video card by doing so?
tl;dr - Currently running two Asus nVidia GTX 480, water cooled, want to hook up the third but don't have a free PCI-e connector on my PSU, want to know if I can use a secondary PSU and how to do it.
Thanks in advance.
P.S. I ordered another, modular PSU with plenty of PCI-e and molex connectors just a few minutes ago, should arrive in a few days. I just want something for the time being - can't wait to try my new cards!|||It is possible, BUT it is VERY complicated and requires wiring, soldering, splicing and so forth to ensure that both psu's work correctly and together. It is my understanding that when this is done one psu is used to power the cpu/hdd's/cdroms/sound card/mobo/fans etc and the second is used to power the gpu's. I have only ever seen this mod needed on EXTREME systems (for example a SR-2 motherboard with TWO Xenon 6-core cpus, 24gb RAM, 4-way SLI GTX480's, dual loop water cooling all in the same system when a single 1500watt psu wasn't enough. The system above was pulling something like 2200watts on full load .
I would personally either buy molex adapters: $4.99 each

or buy a psu that can handle 6 pci-e connections:

*Edit* didn't see the part where you said you ordered a psu already. I would try to get those molex adapters and best buy or frys or something nearby, or just wait it out. not worth the risk imho|||I don't know for sure, but I think the PSU has to rely on the bios to work right and if not recognized by the bios, it might not run.
Power supplies go through a power up self test and if everything is working that has to be powered up, the psu keeps running. If it finds a problem, it shuts down. So I think, the psu needs the POST to keep running.
I could be wrong.|||I wouldn't risk it.

Is one graphics card enough?
Im planning to build a new rig with all the recent stuff and here are the planned specs:
Intel core i7 930 cooled by corsair H50
MSI Big Bang X58 XPower mobo
3x2 gb of 1333 mhz corsair ddr3
120 gb corsair SSD for games and OS, 2x 1tb HDD for media stuff
corsair 1000w modular PSU
GTX 480
Cooler master HAF 932 case
combo drive
The only 2 question is will I be able to run al the recent and the "coming" games on the highest graphics with one GTX 480 card or will I need to SLI two? If I need two, will the 1000w psu be enough? Oh keep in mind that If I use one video card that will be water cooled.|||That's some monster machine and you can have 6 graphics cards but they don't recommend using more that three! since one 480 can beat the snot out of any game out there one will be more than sufficient...as to the "future" ...well There is tech being developed to make the 980X obsolete, new PCIe version 3.0 is almost out with version 4.0 on the drawing board. New chip sets to handle an improved version of SATA and USB...oh..and LightPeak...a miniaturized fiber optic unit that converts electronic data to light speed and of course equipment that can use it...wouldn't it be nice to have just one connector (fiber wave guide) built into your mother board that will plug in to your hard drives and CD/DVD drives to send and receive data at much higher speeds (bandwidth) than today and use less energy to do it! I wouldn't be spending huge bucks just yet!|||IMO 1 graphic card is enough in 99% of cases. I doubt theres anything you REALLY need 2 for. Some people will say otherwise
And 1000w is way more than enough for everything.
These days the hardware is catching up to the games. Even so called “budget” gpu’s can max out games.
And a word of advice, don’t put your games on the SSD thats for your OS|||one card should be enough i have one myself very powerful card, i also have the same power supply corsair are great i would say if you wanted to run another card you'd be fine with psu you have.|||Do you really need to play StarCraft 2 with max specs?!?! :)

Water Cooled PC?
I'm planning to buy a
Motherboard - nvidia 780i sli
Processor - Core 2 Extreme QX6800
Video Card - evga geforce 8800 Ultra KO
Case - Cool Master Stacker 830 Evo
I'm planning to leave everything at stock performance, not going to overclock anything. So should I air cool my pc or water cool it. I'm going to mostly use this pc for gaming, but again not overclocking anything.|||Unless youre doing some extreme overclocking you dont need water. Just get a nice Zalman 9500 or 9700 and some Artic Silver 5 paste and some case fans front and back sucking in the front and blowing out the back. Running water requires maintenance and and can get a lot of clock out of that quad with a Zalman 9700 without the grief of water even if you do decide to overclock it.|||dude... the stock cooler is good enough if your NOT going to overclock.
with stock cooler, no overclocking, its FINE.|||go with air cooling but make sure you have enought fans so that you can suck cool air from the front and then have a fan at the back to blow the hot air out. Since you are not going to coverclock you souldnt need to have watercooling.|||h2o! that stuff will still get hot. and h2o is quite and much better at cooling. if you do decide later to overclock you'll be good|||If your not going to over clock stick with the air.|||if your water cooling fo with a lian li, if your just keeping it stock go with the cooler stacker 830 and go with zalmans|||That PC will make much heat, use water cooling system.|||Since you mention the specifics... I think you might want to stick to air cool, after all since you are not doing anything on extreme upgrades, you can use the extra saved cash for games, simple and easy to cool your pc, by just keeping it off the carpet ( to avoid static/and or if you have a carpet) and on your desk. water cooling is just fancy thats all.|||Air cool. its cheaper.

High temps with water-cooled Phenom 9950BE?
I have recently built a new system with the Phenom 9950BE with the intention of overclocking but when I checked the temperature it reads around 45 degrees on idle. I have an Antec 900 case with all the case fans on the highest speed. The rear fan was moved to the side of the case to make way for the water cooling kits radiator/fan. The power cables are not obstructing the airflow in any way and the water tank and pump are placed next to one of the front fans to cool better. I used the themal paste and coolant that came with the water-cooling kit.
System Specs are:
CPU: AMD Phenom 9950BE
MB: Asrock K10N780SLIX3-WIFI
RAM: 2x Corsair DDR2 Twin2X 4096 6400C5 4GB (8GB Total)
Video Card: 2x Zotac GeForce 9800GT 1GB (SLI)
PSU: OCZ GameXstream 850W SLI Ready PSU
Case: Antec 900
HDD: Samsung 500GB
Optical: LGE GGC-H20N/L Black Blue Ray HD Combo
OS: Vista Ultimate 64-bit
Water-Cooling: ThermalTake ProWater 850i Liquid Cooling System Kit|||I suspect the thermal paste is the most likely suspect. I always use Arctic Silver 5, so I don't know about the quality of the paste that came with your liquid cooling kit. Ensure that you didn't put too much of it on your CPU, that can seriously screw up the heat transfer.

Is liquid cooling quieter than air cooling?
PC parts are getting faster and as a consequence are putting out more heat. To get rid of this heat, fans are getting faster and noisier. I'm right next to my PC most of the time and the noise pollution is really starting to bug me. As I consider a new heat generating video card, should I switch to water cooling as well to cut down on the noise? Is liquid cooling quieter than air cooling?|||Yes it's quieter, but you're just trading one problem for another.
The noise reduces, but then you got to put in fresh liquid since even the best ones start forming algae over time. Very messy to handle all that!
*
*
*|||Usually yes. The water may cool the computer parts but something has to cool the water, i.e. fans.
of course on low end systems you could get a radiator with no fans, a passive cooling power supply, and ssd's
the only sound then would be the pump and high quality ones sometimes are silent.
if you have something extreme you usually would get a 3 fan sometimes 4 fan radiator, so 4 120 mm fans plus hard drives, plus pump.
still quieter than what air cooling by itself would do.
Remember that peltier coolers are not safe if they are low quality because they might cause condensation. They also need a fan or liquid cooling on the hot side.
so the more higher end it is the louder.
for fans i recommend noctua fans, they are dead silent yet move more air.|||yes and no. Liquid cooling has a fan that blows on a radiator, thus the fan can make noise, also the pump will make noise depending on how cheap it is. The quietest cooling option one has is called peltier or thermalelectric cooling, this takes a lot to setup and I have though about doing it on my computer this can potentualy get the cpu to just about freezing temp. But even this will require a cooling fan.

Will an HD 6950 1gb video card cope with battlefield 3?
Setup im getting comes with:
1090t BE 6 core OC CPU with Antec water cooling
Asrock 890 Extreme4 MB with USB3, SATA3,eSATA3 and Firewire,
HIS IceQ X HD6950 Graphics
16gb Ram,
2tb HD,|||More than enough power.|||Yes, I have a 6950 and have all settings on High except the terrain textures and a couple others that I have at Ultra, and I usually get 50-60FPS.|||I have an XFX 2GB "XXX" version of the 6950, and I run BF3 easily with all settings on ultra (I turn AA off) and I have the Phenom II x6 1090T as well. I average 50 FPS. If I turn a few things down a hair I get over 60 FPS no problem. So yes- you will be able to run BF3 even with a reference model 6950, and especially with that HIS model which is a very good one.
Its a great card and you'll absolutely love it.
FYI- I can also run Crysis (the original) on the highest settings and still get 30+ FPS. It looks pretty freakin amazing running at 1920 x 1080!|||Battlefield 3 recommends a 6950, one would hope that this card would play it
I personally think a 6850 will play it just as fine (if you look, gtx560 is the same price as the 6950, to me this suggests that the developeers only looked at the nvidia card then price matched it to newest thing)
Edit: That true dfsdfhgf...? what about your other system specs (if you are running a pentium dual then its completely logical to not be able to handle it)
System requirements lab is pretty cool, though they require you to install an add on (which I hate) I would look up the recommendations and compare it with your system, don't know how to look at system specs? right click "My Computer" and left click "Properties"|||yes :]. I have a gtx 570, which is basically the nividia equivalent of your hd 6950.
though I can't run it on ultra with a full resolution, I can play it on high with no AA on full resolution.

Re: computer wont turn on with video card?
my RAM & video contacts were clean, but yesterday i took out my video cards and pwerd on the computer, then with it on, i slid the video cards into their slots and noticed that a spark came from one of the pci-e ports and the comp shut off, i tried again, then there was some smoke & smell. i removed my video cards and found that the left pci-e slot burned 2 contact pins on my video card. i took a look at the pci-e port and there were those 2 same pins in there but displaced a bit. because of water cooling and case restriction, my video cards sat a bit crooked; there was a little more space to push that card forward but the case was in the way.my computer worked fine for a month after i replaced my psu, but i think when i took it to my friend he had a hard time taking my video cards in and out, and remember he jammed that parcticular slot a bit lol; i should have done it for him becase my cards are in the tightest spot.
with those 2 scorched marks can my video card still work?|||Don't put computer components in with the power on! Only way to see if it still works is to try it out, but you probably fried it.|||u probably fried your card / mobo. u can always try a friends video card... but i believe any sparks are a sign of a fried board. been thru tons of circuit boards with sparks... next time make sure you're grounded when working on parts. static electricity is a bich. burning smell and smoke? yea thats a bad sign.|||if you saw a spark, your mobo is probably gone....ESD got the best of you on this one...|||Why ask us? Youre there with your puter and video cards. Plug them in and see. You have water cooling 2 video cards in SLI or Crossfire and you plug video cards in with the power to board on? Geez. Your board and/or cards are fried.
Sparks on jumper cables are ok--in a computer its not ok.|||power on the pc with the video card out you should get a beep
code from the pc that is a series of beep tones that trouble shoots the mother board if you get no beeps your mother bd may be toast as well.....if you get beeps write them down they'll
be long & short ones then call the manufacture and find out what they say.......you could try another used video card but you might
blow up and thing you put in that slot
