Atx Power Supply Question


I need a psu, but the server i need it for has a strict 24pin atx connector (not a 20+4 or any other variation). That's compaq for you. Check the pin config and let me know which psu i should purchase. Links to newegg or tigerdirect are appreciated. I really couldn't find a decent 24 pin atx psu @ newegg. I'd like to get a quality psu like an enermax, because this is a server after all and it will be on all the time. The original is beginning to die (fan starts going nuts).

Power Supply Problem

I have been messing with my two computers trying to upgrade them with the parts from one putting them into the other, since the computers are almost the same. Well, as soon as i plug in the power cord to the power supply, it sounds like it is starting up for a second, then shuts off. Then the computer wont start at all. It seems like a fried power supply to me, but i wanted to get other peoples opinions. What could it be besides fried?

Power Supply Wattage

My brother's power supply died and he asked me to help him find a replacement. He built the computer about 3 maybe 4 years ago so it's due for a memory upgrade at the least and probably a new processor. The old supply is 400 watts, but i'd rather he bought a better one, maybe 500 or 600 watts at least so that he can upgrade later without a problem. Will a higher wattage affect his current hardware?

Possible Power Supply Issue

I have a system i built myself i have a asus motherboard and amd sempron 2800 1. 7 ghz processor with a 350 watt power supply, 512 ram, dvd combo drive and 80 gb hard drive. I have this problem where i can run windows pro fine for a average amount of time and after i do a shutdown and the system completely shuts down i push the power button to bring back up the system and only the fans come on. No power what so ever to my hard drive or dvd burner and obviously my motherboard isn't getting power either. What have to do is unplug the power from the back of my power supply for about 15 min and plug it back in and everything on my system get all the power back to it.

Power Supply Problem / Spark

Today i had my second antec 300 watt smart power go boom on me. When i say boom, i mean boom. Sparks and loud noise then the air smells funny like burnt wire. I have no clue what can be causing this. I have my other machine (with an enermax power supply) plugged into the same power strip(which may be the problem). Any ideas of what can be causing this? Could the motherboard be causing this some how or am i just really unlucky with power supplies?

Problem With Case / Power Supply

I bought a case and put some older components into it to build a new system. When i powered up the monitor would never come on so i tried replacing each component. I add new motherboard, new processor - all with the same problem. I do not even get a signal to the monitor or bios info or anything. The only thing left to replace is the case/power supply. Is there something i should be taking into consideration when buying a case/powersupply - i had thought that was fairly straightforward?
The case is: jnc 4ja h7650 blue type 3 atx midi tower case 300w psu front usb firewire & audio, my motherboard (msi km2m combo) has on-board graphics & ddr and sdram (i've tried both) bought as i thought initially the graphics card might be a problem.

Power Supply With Pentium 4 System

Anyway, i am planning on building a pentium 4 system and was wondering what power supply to use. I have used psu "calculators", but is it okay to go with more wattage than it says. I don't want to fry my motherboard. Is there any danger to giving it say, 400 watts, if it only needs 315? I might be upgrading later.

Computer Shuts Down Power Supply

My randomly shuts down after about an hour or so and when i try and turn it back on it lasts about 1 minuit then it switches off again. After about 3 times trying to turn it on it beeps about 4 times then it says "cpu overheated" then some windows restore stuff then it switches off, at first i thought that it could be that the processor fan wasn't working because when i took the cover off the metal bits around the fan were very hot. I dont know what to do about this and i have no idea what is not working. I don't know why the cpu is overheating because the fan that cools the processor is spinning. If there is a fan on the power supply i dont think it is spinning because i cant feel any air coming out. My motherboard is an asus p5gdc and there is a a nvidia geforce pcx 5750 plugged into the pci-e x 16 slot and there is a modem which i have never used in one of the pci slots and two 256mb sticks of ram in the blue slots and thats all. There is a fan in the back of the case, a fan covering the processor i think there is meant to be a fan in the power supply and there is a fan in the side. Does anyone have any idea what this problem is and what can i do about it. It normally shuts down when im playing games. The only games i play are the sims 2 and halo, my problem first started when i was playing sims 2, the first times it happened it didnt shut down, it only restarted. Then it started to shut down and keep shutting down with the cut out time becoming shorter and shorter. Anyone had this problem before?

Antec Power Supply Failure

I've built quite a few desktop pcs systems, from motherboards, etc. And, i've also repaired quite a few machines (e.g.compaq, hp, gateway, etc). It seems that power-supplies are the failure point much more often than i had expected. Once again, a couple of days ago, on a six-month old machine i own and built, (with good fans, no overclocking, etc), i inserted a 2nd ethernet-pci card into it, and when i brought it up for the first time, it wouldn't boot. (No smoke or noises. )The little activity light seemed to indicate random action, just as though it was seeking the disk and booting, but nothing ever showed up at the console, not even initial bios output. So, i took the case-side off, and hooked up my little power-supply tester-unit. Sure enough, one of the tester's multiple green lights did not light up, and that red 'danger' light on the tester did light up! [It's a fairly nice antec 400-watt supply, which is plenty of wattage for this system. It is an antec model sp-400 'smartpower'. ]

Any advice or comments about how often power-supplies fail, or thoughts about why this one might have?

Power Supply That Has Two 20-pin Connectors

I'm looking to replace a power supply on a magma chassis that is used to supply power to 7 hd cards for a pro tools system. The current power supply is just loud as crap and i need something quiet. The current model is made by channel well technology, 400 watts, and the model number is psg400p-89. The difficulty i'm having is finding a power supply that has two 20-pin connectors on it. The power supply uses two of these connectors to power the main board. I noticed a splitter on ebay that takes one 20-pin connector and splits it into two, but i don't know that this would give me the right amount of power, would it? I'd probably rather have something that had separate connections running straight from the unit. I also want it to be quiet, since that's the whole point of me doing this in the first place.

Power Supply Adapter Myth

I recently built a new computer and noticed my power supply has a 20 pin connector to the m/b but i need a 24 pin. So naturally i am trying to find a little adapter that makes the 20 pin into a 24 pin male for the mobo. I heard from some people that there is around a 50/50 chance that this adapter will fry my motherboard, or possibly my power supply. Is this true?

Jumper Power Supply Permanently

Basically, are there any power supplies that i can "jumper" permanently. My goal is: i have an empty atx case, but as far as i'm concerned, its an 8 bay hard drive nas case or how ever you want to look at it. I had the default power supply in it, and i jumpered the green and the black pin to keep the power on with out a motherboard and it worked great! But after a month or so, the power supply did die, as all the blogs/forum post suggested it would. Is there any thing i could do to power 8 hard drives in an empty case, with out a failing power supply? Do they make power supplies that are able to run with out a motherboard? Or perhaps an option i have yet to find?

How Important Is Amperage In Power Supply?

I am trying to decide weather i should get a silverstone 500w psu (power supply) or a hiper 580w . Now the silverstone has a total combined amperage of 36 @ 432w while the hiper has 30a @ 360w. Yet the the silverstone only has 150w total for 3. 3v and 5v @ 25a each while the hiper has 280w total for 3. 3v and 5v with 3. 3v @ 28a and 5v @ 36a. How important are the 3. 3 and 5 volt rails for a gaming pc?

How low is too low for such a system? Should i go for higher 12v and lower 3. 3/5v or vice versa?Please try to be as objective as you can. I know that silverstone is a very popular name and i would hate to have information skewed by biased opinions. I have read that newer mobos do not need high amperage on the 3. 3 and 5v rails yet i like to view more than one source on such matters.

Moniter Issue After Replacing Power Supply

Ok from the top. One morning i came downstairs and i noticed the room was really dark. I had left my computer on overnight and i saw it was turned off. I knew right away there was a problem inside the computer. I opened the computer and noticed it smelt like burning wires. I took a whiff of the fan in the power supply and noticed that's where it came from. I turned off all power going into the computer and took apart the whole power supply. I unscrewed the board and looked underneath and noticed the whole bottom was melted to the metal casing. I took out the power supply and put in my old one. There was only one problem, a 4 pin atx inlet was missing that goes into the motherboard on the far side by the intel 4 processor. I closed everything up and plugged everything in. I turned on the computer and it was working as it should. Then i saw the moniter wasn't working. I rebooted the computer and watched the green dot. (It didn't blink for 5 seconds and then it started blinking again. ) I checked all my hardware it was all working fine. The video card, radeon 9800 was working, the fans all ran fine. I cannot resolve the the problem can someone help me?

Replaced Power Supply Now Monitor Not Getting Signal

I first looked at it and determined that the power supply was bad so i replaced it. I see the fan above the processor has started and it sounds as if the computer has started but my test monitor will not get the signal. Along with my monitor not getting the signal, it appears as if the keyboard and mouse are not getting power as well because the mouse has a light on it which comes on when it gets power. I also attached a thumb drive to the pc and it too does not get power to it. I am thinking that the board was damaged when the power supply went out but if anyone has any suggestions as to what else i should look at i would like to hear it. Btw the computer is a e-machines c2280 and not too sure what the other specs are since the computer was broken when it was brought to me.
