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.

Difference Between 4/8 Pin And Sata Power Connectors?

For a hard drive, what is the difference between 4/8 pin power connectors and the sata power connectors? Do i need to use both in order to power my hard drive correctly? I noticed that there is an 8-pin power slot, but i also know that the long sata slot on the far left is also a power slot, and i was just wondering the difference between the two.

I have an evga 133-k8-nf41-ax sli motherboard and it has both a 4 pin and a 24 pin power connector. I have only been using the 4 pin. Should i have the 24 pin connected to the psu as well?

Dual Supplementary Power Connectors

Just bought a pny 8800gtx xlr8 768mb card. Ready to install it but surprised to find that it has dual power connectors. (Dual supplemental power connectors). It appears i need to use 2 power connectors for this card. No problem, my power supply came with 2, for running sli, but what am i to do if i want to run 2 cards? I only have 2 rails set specifically for pci-e cards. Guess i will need a new power supply with 4 rails if i want to run sli.

Problem With Power Connectors On Ga-ma790x-ud4p

I got all my power cables hooked up the way they should be, except there is still the, what the motherboard calls, atx_12v_2x4 plug that has nothing plugged into it. After looking at the cables from my power supply, i see that the only one that looks anything like it is what the power supply calls the 8 pin eps12v cable. The pins don't look the same, but it will plug in. (There is a couple hexagons where a square should be, but it still can fit) is this where the cable is supposed to go or does it not need anything plugged into it?

Motherboard: ga-ma790x-ud4p
Powersupply: cmpsu-650tx
Video card: pny gtx 260

Nvidia Gtx 460 Power Connectors Problem

I got a new nvidia gtx 460 which requires more power than the motherboard can provide and has two 6 pin (2x3) power connectors. Unfortunately, i have no idea how to connect them to the power supply. I currently have a 500 watt power supply, so do i need to upgrade it, or is the problem simply the one of finding the right cables and/or adapter?

4 Pin - Pci-x Power Adapter

Can't believe my psu nor my video card came with one of these adapters, now i have more wait time. Does it matter whether you get the 2x 4-pin -> pci-x adapter, or the 1x 4pin -> adapter is sufficient?

I'm looking at building a computer with a ocz ocz500mxsp psu and an asus m4a78 plus motherboard. I've spent the night trying to make sure all my components will work together, but i noticed this and am not sure if it will work.

Connect Power To Hard Drive With 7 Pin Connector

The hard drive in my desktop took a nosedive. A friend gave me an hp tower with a bad motherboard. The data and power sockets on the hard drive have the flat blade type connectors. So i swapped out the power supplies too. My tower has a gigabyte motherboard. Now, i can connect everything except for the power to the hard drive. It has a flat ribbon connector that goes from the flat power socket to a small 7 pin connector. My gigabyte doesn't have the 7 pin. How can i power the drive? Is there an adapter made for this kind of connection or am i just out of luck?

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.

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 / 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?
