Power supply has no 6 pin connection

[Gamerguy207]

Help I was thinking of getting a new card but my power supply has no 6 pin!!!!!!!! Btw the wattage is 400w

molex to 6 pin

[Oshino Shinobu]

If your PSU has no 6pin PCIe I would probably consider upgrading it.

Never molex to 6 pin. A new psu with a 6 pin should be less than $60 and will save a fire.

Try using some deep though and logic to analyze why a PSU that does not have a 6 pin connector may not be ideal to use for powering a device which requires such 6 pin connector.

He can get a photon 750 watt thats what I have.

 

It has split wires (8 pin, and you can split it to 6 pin) I got it for like $100 not bad for 750 watt and it does its job

There are a few power supplies out there that don't have a 6pin pci-e connector simply because they're pulled out of OEM computers that had onboard graphics, or because it's a subtle way to push customers to buy more expensive models of the power supply.  For example, a modern 360w power supply may not have 6pin pci-e connectors while the 420w model may have one or even two pci-e connectors... but both are actually powerful enough to power cards with a single 6 pin pci-e connector.

 

There are quite a few video cards out there that only slightly exceed the maximum power limit of 60 watts, so they need to add a 6pin pci-e to respect the standards. For example,  AMD RX 460 will use around 70-75 watts, maybe a few watts more if you buy the 4 GB version. 

So basically, instead of taking 70-75 watts from the pci-e slot, it will take 30-40w from the slot, and 30-40w from the pci-e connector.  For the power supply, it's just a 20w difference either way

Other video cards could actually work without any 6pin pci-e connector, but they may add one so that the video card would "look" more powerful (like the racing strips on cars... it has a 6pin connector, so it must be fast and powerful, says the "noob" buyer) or they add one pci-e connector so that the card could take extra power in case of overclocking.

 

So without knowing what power supply poster has, or what video card he's planning to use, don't make assumptions.

 

@Gamerguy207 , it would help if you tell us what power supply and what video card you plan to use. If you don't have some brand name power supply, look on the label of your power supply and determine the current available on 12v -  multiply the current by 12 and that should tell you how much power the power supply can provide on 12v : for a system with a video card that needs a 6pin pci-e connector, the power supply should be able to provide at least around 250 watts on 12v, or at least around 20A.

If it does and you trust that power supply, than you can buy adapters which convert one or two molex connectors (the old hard drive connectors) into a 6 pin pci-e connector or a 6+2 pin pci-e connector and you can leave those 2 extra pins unconnected.

well, if linus has done it, and ive seen other reputable sources do it, you should be fine.

Idk about you, but I don't consider house fires to be fine.

What PSU do you have?
What Card do you have?
How does the rest look?
 

If your PSU doesn't have a 6pin PCIe Connector, it's mostlikely absolute garbage or 20 Years old (wich makes it garbage)...

 

And with some more or less modern business PC Power Supplys it's a rather dumb idea to use any S-ATA or Molex Adaptors to PCIe - because you may burn the board!

[Princess Luna]

Only use molex to 6pin if the PSU has the needed watts to supply the card otherwise you will throw more demand that it can deliver what will end up killing a component.

1. We still don't know what PSU he uses, so without that knowledge, you better not give this kind of  tipp.

 

2. ...and the PSU has the connector...

There are many OEM PSU out there that only have one or two connectors for the board...

Excuse me, but it is you who should better not try correcting people like that, I said that he should pay attention to his wattage, if there is no pci-e connector it probably is under 300w regardless and if the graphics card he wants to use requires a 400w PSU for instance HE WILL burn something forcing it with the molex adapter REGARDLESS the brand and model.

And what about the quality of the PSU?
What about the age of the PSU? 
There's a lot of PSUs from the olden days that don't have PCIe connectors.

And there's a whole lot of low(est) quality units out there that have no PCIe connectors and are labeled '500W' for example this one. The Inter Tech SL-500.

 

So again, without knowing what PSU he has at the moment, you should NOT tell him to get any kind of adaptor!

Because maybe there is a reason the PSU doesn't have any PCIe connectors...

What the hell is the matter with you, I told him not to get it especially due to the power is more than likely not enough, and now you're trying to say I was telling him to? Grow up.

You said "Only use molex to 6pin if the PSU has the needed watts to supply the card".

 

So what you were suggesting was that if the power supply has the require rated wattage, he can used a molex to 6 pin adapter. However, there are PSUs with designs from the pre-ATX 1.3 era that has a high enough rating that is supposed to be capable of powering a <~150wDC card (a GPU with 6 pin PEG connector will not require a quality 400w) should NOT be powering a modern day GPU.

 

The reason being those PSU, despite being rated "appropriately", were design to power systems whose power draw comes mostly from the 3.3V / 5V rail and not the 12V rail of today (some of those PSUs will also have inflated 12V rating as well to give the impression that it is capable of doing so). Because of this, if the OP has a 500w PSU without a 6 pin PEG connector, it actually a bad idea to immediately make the suggestion to use that sort of adapter, as such we should ask for the power supply model first.

Quality is medium and is not a popular one but is has one problem with power is is rated for 400w which is more the enough for what I need

It's 400w and is more then enough the handle what I need so how about YOU use some common sense and find a solution instead of complaining about my problem

Why won't you just answer the question?

What PSU do you have?!

If you don't know, make a picture of the label and upload it here...

 

Without knowing what PSU you really have, we can not help you!

 

Or maybe you want to end up like this?

You made a thread asking a question on a subject that you do not understand, and when he made a comment that you don't like nor understand, you attacked him for it?It is true that there are quality OEM PSUs that may not have the necessary PEG connector, but what you just did is called "Biting the hands that feeds you". What he brought up was a legitimate concern.

 

As for a solution, well, that adapter may or may not be a "solution"

Again, just because it is rated as a "400w" doesn't mean that it actually is capable of power your system.

Check this review of a "680w" power supply. http://www.jonnyguru.com/forums/showthread.php?t=6714

You will noticed that it violated ATX specification by 6 times over at only 100w load and continue to do so beyond 200w before burning out. This mean that this 680w PSU isn't even a 100w unit.

 

So can you please provide a model or a image of the PSU specification chart?

Seeing that you have a IBuyPower mouse, can I assume that this PC is from them too? IBP, CBPC, etc. have the tendency to use very low quality PSUs based on an outdated design on some of their prebuilds.

[Ringthane]

Well, if the OP wants to risk damaging not just his shiny new video card, but indeed his entire computer itself, by using a low-end, perhaps underpowered and low-quality power supply, we can't stop him.  

 

OP - please listen to what people are saying.  Do yourself a favor and upgrade your power supply.  There are certain things you should never scrimp on when building or upgrading a computer.  Your monitor is one, since you spend your time at the computer staring at it.  Your power supply is another one, since if it goes, it can and (most likely will) take more of your computer with it.  I've been working with computers for 20 years.  I've seen it happen.

[Stefan Payne]

ANd if the PSU is low enough quality, it can even take out him, his house and/or all of his belongings...
