Bronze 6+2 pin vs Gold 8pin

post #1 of 6
Thread Starter 
Hey wonderful community!

I'll try be as clear as possible...

I currently have a 1000W bronze PSU. It only has 6pin available on the module. My graphics card is a SOC GTX 680 gigabyte edition which requires 2x 8pin. Because of this I am forced to use 2x 6+2 pin for my GPU (so it's actually drawing power out of 6 pins, and the extra 2 pins are sharing 2 of the 6 pins)

https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcTIOqi0yfF4rZo-Am1zQnF-jwQldM9dXtF8xlJx6Aa7j8RWKsCX - link of 6+2 pin

http://www.gigabyte.co.nz/products/product-page.aspx?pid=4309#ov - is the link to the GPU smile.gif

THe question is!! If i upgrade to a Gold PSU (i know this is to do with energy efficiency, however can this ALSO help with overclocking capabilities because the power is cleaner?)

Second question, if i used the 8 pins to 8pin connector on the new PSU module, would i notice a difference in OC capabilities and/or performance from the 6+2 pins?

I hope that was clear?


Cheers,

Daniel

Im no PSU expert . But the power doesn't come out of the pins, It comes from the actual output of the power supply so the 6+2/8pin thing doesn't matter.

It matters which power supply provides the best power (moar amps) and most steady power.

EDIT: An electrician would probably tell you that there will be more resistance using the 6+2 variation but to my knowledge you will not notice a difference.

Also, Post your System specs in your rig. Makes life easier for everyone:)

Naw you are actually completely fine with that PSU. It doesnt really matter whether or not you have an 8 pin or a 6+2 pin, they both give the same amount of power, its just that the 6+2 pin was designed in mind so that you could use only the 6 pin if you do not require 8. There is no need for an upgrade, because your PSU is wayyy more than enough to power you system. Your current PSU could power probably power two exact copies of your system even. As for the Gold power supply, it could have a possiblilty of giving you slightly cleaner power, but the difference is really negligeble, it would be near impossible to tell the difference.

Thank you so much for the quick replies guys smile.gif ... So a gold PSU wouldn't actually help me OC my GPU higher at all?

You just saved me a heap of money ^_^

The 80+ certification (bronze, silver, gold, etc) has nothing to do with power output, it -ONLY- refers to the efficiency in which the PSU converts AC power from the wall into DC power for the components, and nothing more. It does not provide a means to judge the cleanliness of the power output, nor does it have anything to do with the overall build quality of the PSU itself. I will repeat, 80+ has absolutely nothing to do with the quality of a PSU or the quality of its power output. Now, do PSU's with an 80+ Gold sticker generally have cleaner output than Bronze sticker PSU's? Generally, yes; but is this always true? No it is not, a good example would be the Antec Signature series, an 80+ Bronze PSU that has voltage regulation and Ripple suppression to rival or even exceed the values of PSU's like Corsair's HX series or even Seasonic's X series of PSU's. Buying based off of the 80+ sticker (which a lot of uninformed people do) is not a good idea, because unless you are a 24/7 Folder you will only be saving a few extra cents per year on your power bill through normal computer use, because most of the time your system will be idling which is where having a high-efficiency, and especially overkill PSU does not matter. And to top it off, many Gold and Platinum 'rated' PSU's are overpriced because of the marketing hype, there are far better deals to be had with other PSU's that have lower efficiency but just as good (if not sometimes better) power output than the 'Gold' or 'Platinum' competitors.

tldr; 80+ does not matter except to people who Fold or BOINC 24/7, stop using it as a way to judge PSU output and build quality.

Edit: sorry if this came off as a harsh rant, but this issue extends to quite a few people in this forum, and I will do what I can to fight this misconception.

lol, as long as the rant is educational, it's completely fine. tongue.gif

So bottom line that this post had. 6+2 pin vs 8pin, there is no difference.

Bronze vs gold - not worth switching from as its only pro is that it is supposedly cheaper. As far as OC capability goes, no difference.

Cheers guys smile.gif
