Need another 6 pin

[sirbonneville]

Hi all. I have 1 x 6pin connector for my PCI-E cable coming from the PSU. I need two for my GPU. Can I buy an adapter? Can I use a 1 x 4 pin from my motherboard?

A Y Splitter like this is what I am thinking. https://www.amazon.com/JacobsParts-Express-Power-Splitter-Cable/dp/B00JLU0UQ4/ref=cm_cr_arp_d_product_top?ie=UTF8

If your PSU only has one 6 pin PCIE, you should really consider if your PSU is enough to power said GPU.

There are adapters from 2x molex (4 pin peripheral, not to be confused with 4 pin EPS for your motherboard/CPU) to 6 pin adapter, but I have not seen them from 4 pin EPS to 6 pin PCIE.

I'm not sure about their quality and would be hesitant to recommend something like that.

My GPU is a 670, then 12gb ram and an i5 4460. My PSU is an 80+ bronze 450 watt, should be more than enough I think.

I just need one more 6 pin.

get a 500w. don't use a 450

Why?
What good does the extra 50W do him?
Have you ever measured a real PC with a powermeter in your life??

[andrewmp6]

That 6 pin spilter should work,But i would think hard on upgrading to a psu with more pci-e cables on it.What if later on you want a 2nd video card to sli it ?As is your kinda out of luick on that but a new psu you could go sli.

In my computer hardware class in college I was taught to have overhead and also by not having enough pcie plugs proves that this power supply needs upgraded.

Overhead, or lack thereof isn't much of a concern so much as the quality of the power supply itself. A decent quality 450 watt should be able to take a quad core cpu and a GTX 1080 (stock clocks) without problem. As this is the component that could kill everything in a PC if something goes badly wrong, it is advisable to not cheap out here.

What PSU is it?

Oh dear...
Look at that Picture:

 

You still think you need "overhead"??

 

That may have been true 10-20 years ago but in the last 10 years the quality of PSU gotten so much better that you can without problems use 100% of load and that is what they are designed for. 

To make it worse:  Most decent quality PSU are certified for at least 40°C ambient temperature, some even 50°C...

 

Also some manufacturers advertise their wattage as "continuous Power". Antec for example. To distunguish themselves from the peak rated crap.

 

Again, your Teacher was wrong and told you things that might have been true more than 10 years ago, but today has no basis in facts, especially if we are talking about mid to high end units.

 

Please print out the box or share the picture of the box of the 850W Bitfenix Whisper M or this Posting with your teacher. ANd see what he has to say about that now.

I don't go to that college anymore but the book we used was the CompTIA A+ Guide to Hardware and it talked about overhead and it was the latest book back in 2015 that we used. Plus that professor has been in IT since 1973, been a professor for 10 years, and I think is now working on his doctorate. Also, most websites online are still saying you need overhead. Also OP says he has a 670 and Nivida's website is saying min 500w psu is required.

Yes and?
How long did they need when they collected the information? 5 Years? 10 Years?
What Processors and graphics cards are in that Book?
What Windows is Mentioned? XP?
That are some things you can use to time it.

 

And things in IT change - and they change fast... 

 

Thinking that something that stands in a book, that's probably a bit on the old side has some values now is just wrong, in an area that changes faster as you can print books..

Irrelevant...

Because in the last 10 years PSU changed more than in the 30 years before!

You can take a look at AT PSU from the early to mid 90s and see that the topology is practically the same - minus 3.3V and the +5V Standby circuit than in late 90s ATX PSU.

Some (Seasonic) PSU also look like they were indeed reworked AT PSU...

 

And today things are completely different. PSU work completely different, use completely different topologys and components!

 

Because in those days there were no low ESR/Low Impedance capacitors.

In those days there were no MOSFETs in PSU at all.

In those days they didn't even have PFC! or newer/OEM ones just a fat coil in the input (passive PFC).

 

Old PSU had most power on +5V, modern have most on +12V.

Old PSU used some PWM mode topologys - with power Transistors for the primary side and Schottky Diodes for the secondary side.

Modern PSU use MOSFET for both.

 

And the quality of PSU was in general pretty bad in the early 2000s, especially for endusers there were no real good PSU...

Especially what you call now 'named brands', they either didn't do PSU or they were garbage.

 

And the rest so so...

 

 

You just have to look at the efficiency:
It rose by around 20-25percent points!

 

low 70% (if you're lucky); 75% max to today ~95% maximum efficiency.

 

That alone should show you that there was some change that made the "old knowledge" just useless...

Yes and some people still tell the tale of 'PSU Aging' and that they will loose power because of capacitor aging and things like that.

That doesn't make it right, there is NO EVIDENCE for it to be true, quite the opposite.

 

So just accept that whatever was written in that book was wrong, false, too old or just so superficial that it doesn't help nobody...

 

 

Buttom Line:
Modern PSU (since 80plus gold was introduced) are just soo much better, that it isn't a problem to use them to 100%!

Especially the ones we are talking about here, the consumer grade, not the System Integrator shit.

And you also forget the temperature rating of the PSU. 

And we are talking about 40-50°C ambient temperature....

 

And that might be what you are talking about: that the book assumes the PSU is rated for 25°C ambient temperature or something like that and used under 40°C ambient or something like that.

in that case (and only then!) it is right.

But with the opposite, it is not. And most people tend to use those PSU in an ambient of 30°C and less.

It was 2015 and it mentioned sandy bridge. Yes while it was a few gens old it was still recent of a book. Copyright was 2014.

Windows 8 at that time.

 

I am going to believe that book before I believe you because CompTIA A+ Cert is an industry standard certification.

Yes, because a Book that someone wrote, who probably had no idea about PSU is more trustworthy than the box of a manufacturer who guarantees 100% load in a 24/7 situation....

 

It was 2015 and it mentioned sandy bridge. Yes while it was a few gens old it was still recent of a book. Copyright was 2014.

So around 2011. Ivy Bridge was around 2013...

 

So that was just around the time the first 80plus gold PSU came around.

Enermax just introduced the Pro87+/Modu87+ series a year earlier.

www.realhardtechx.com/index_archivos/Page567.htm

 

Seasonic X Series just came out about a year earlier:

http://www.realhardtechx.com/index_archivos/Page678.htm

 

And even Corsair just released the AX series with 80plus gold.

 

 

Now go back to what I've written in my last posting. That was exactly what I was talking about!

Most companys didn't have an 80plus gold unit at the time or were just releasing it within that year or the year before. 

 

But since then the Quality of the PSU increased still a bit!!
