PSU Doesn't Have Slots

My new [strike]cars[/strike] card requires additional power supply. My older gtx 1050 didn't had extra power supply slot on it. I got a six pin cable but there is no where to plug GPU to PSU what can I do?
 
Where does the six pin cable you have go to? Is it coming from the PSU itself? Because that could be the one you need for the GPU. Out of curiosity, what GPU and PSU do you have? Is it a stock PSU? Because usually stock ones don't support add on cards that require external power, but most (not all) 3rd party PSUs do.
 
Yeah my PSU is the stock PSU. GPU is MSI GTX1050 TI GAMING X. And I bought the six pin cable, it wasn't in the case or in GPU's Box . There are some cable's coming out of psu.
 


I think it would be safe to upgrade the PSU. If your not actually sure where to connect it don't do it because some wire have different power variations. If it is a stock then most probably it wont have a PCI-E pin.

If you are upgrading go for the corsair cx 550m.
 
If your case and setup supports a standard ATX PSU:

You can use something like this, but it really is just a bandaid, not the best idea. It will just plug into one of the 4 pin molex connectors.

Better off just buying a new power supply in my opinion.

As an aside, I didn't think any of the GTX1050tis had an external power connector because they were very energy efficient. I looked at a couple myself and the ones I looked at didn't. The reaon your GPU didn't come with the cable is because a power supply that supports good GPUs will have the cable built on to it. The adapter is the cheap way out and it does have to have at least one of the white molex plugs to use (and the "Y" prevents you from losing your connector so you still have it available to use if needed), but a better power supply is really the recommended way to go for the long haul.
 


And that PSU didn't have a name or anything? Just a silver box with nothing on it.

Fine.

I'll get to the point.

Your on board sound could potentially require -5V to power the DAC. This isn't commonly done... in fact, I personally haven't seen it done in about 10 years. But you have an older motherboard so anything is possible.

Intel has since removed the -5V from its spec, so most PSUs today don't have a -5V. They'll just have an empty pin where the -5V should be. The PSU will still work with your system, but some aspects won't work. Like on board sound.
 
You do realize a negative 5 is simply reversed polarity. Switching the two pins that complete the circuit around will fix that. It is a DC circuit. If you have 5 volts, switch the red and black around and you have -5 volts. Anyone with basic DC skills can fix that. Where I work we deal with DC voltage all day, every day. It really is that simple, swap the hot and ground wires, voila, -5 volts if he needs it. My bad, like so many others here, I have a tendency to think that because I understand how something works, everyone else should also. That is why I try to go in-depth when explaining something to people, because often they do not, the same as I don't know everything they know. So for those who do not understand DC circuits, if you need negative voltage, simply swap the red and black wire (usually red for hot, sometimes it can be yellow or some other warm color) and you will have negative voltage.

Don't believe me? Take a multimeter and check a battery. Now, try it with the black lead on the postitive and the red lead on the negative and see what it reads. If you have a digital meter it will show negative.

That being said, he has a PCIe port, which has only been out for 13 years. If they haven't really used the negative 5 for ten years then chances are he will not have an issue. If his PC is over 10 years old, then the GPU is the least of his problems. You said his MB was old. I have looked and don't even see where he mentioned what MB he had.

Sure, the PSU is a POS. That is why it has 176 reviews and average 4 out of 5 stars by people actually using it, LOL.
 
Dearest Bo...

Welcome to the Internet. Good for you that you know about electricity, but clearly you know little about computers and PC power supplies. Allow me to introduce myself. My name is Jon and I started a PSU review site almost 20 years ago called jonnyGURU.com. I've worked in the PC industry for over 20 years and have worked in the industry as a PSU product manager, technical marketing manager and R&D manager for the last 10.

Yes. You can reverse the polarity of the +5V and ground to obtain -5V, but how are you going to do that on the 24-pin that powers the motherboard? You're going to trip the SCP (short circuit protection) of the PSU. That's why ATX PSU's used to have a -5V to begin with. A dedicated circuit that delivered -5V to the motherboard that WOULD NOT trip the SCP. You cannot simply reverse the polarity of the +5V rail and feed it to the motherboard. It DOES NOT WORK.

And yes... he said PCIe port. He also mentioned the onboard sound stopped working when he upgraded the PSU for the new graphics card. But that post or part of his post is now missing. Maybe I got my posts mixed up. 😀 Someone said something about upgrading the PSU and the GPU and the onboard sound stopped working. That would be because the 24-pin lacks a -5V lead.

EDIT: This might have something to do with the missing content in this thread:

And if you think 176 END USER reviews on a retail website is indicative of quality, I encourage you to refrain from suggesting PSUs to anyone. That PSU is single forward topology, no DC to DC, a sleeve bearing fan and no power factor correction. And that's what I can tell you WITHOUT even opening the PSU. I imagine the quality of components within are even worse than I imagine.

 
Sorry for my late reply. I ll upgrade the PSU. GPU requires 400 watt and my psu (FSP250-HMM) is 250 watt. But now I have much more problem =/. İ think after I tried to open PC without powered GPU something went wrong. I put my old GPU(it doesn't require additional power) and now I don't get a display. On forums people say my motherboard is gone 🙁.
