Need PSU opinion

wsarahan · Mar 7, 2014

Hi guys

I just bought this PSU for my rig

http://www.seventeam.com.tw/product_contentx.php?theme_select=1english&cid=165&pid=689

I would like to know if it was a nice choice

My rig is a 4770K @ 4.5 and GTX 780 SLI more 5 Har Drives

And about a single ou multiple rail 12V? I don`t know if this PSU uses a single or multiple, and what`s the diference?

Thanks guys

Yup, that's a Tier 1 PSU. Very good quality.

However, that's still way overkill for your build. I'd go for ~850W, maybe 900.

Single vs Multi is a way overblown topic. That looks like a single rail. Multi rail is a bit more forgiving if you wire something wrong, while single rail ones can make a decent arc welder.

Its a good psu. However 850-900 W PSU would also have done the same thing without putting a hole in your pocket.

Thanks guys

About the price was almost the same

And about the single or multi rail i didn`t get it, my english is not soo good

It does not care if it`s single or multi rail in this case?

Thanks again guys

Someone Somewhere · Mar 8, 2014

Single vs multi does not matter. Either is OK.

wsarahan · Mar 8, 2014

So resuming it`s a top PSu that will make the job as it supposed to be considering my rig right?

Thanks all of you guys

Someone Somewhere · Mar 8, 2014

Yes, but it's bigger than it needs to be and thus more expensive. Where are you buying from? I might be able to find something cheaper.

wsarahan · Mar 8, 2014

The last question

How do i know if i`m using multi or single rail?

Thanks

A 1400 Watt PSU with a single 54 Amp rail? I don't think so.

It's 105 Amps according to Note 3:

The maximum continuous combined load on +12V outputs shall not exceed 1260 Watts.

It also says;"or sextuple independent"

A picture of the psu,

i count six rails.

It also says a max of 105A as a total combined +12V on the sticker and the specs tell that too.

@Vic

The spec on the site says a single rail and the PSU stick says 6 rails right?

What should i trust?

And i`m using the psu at 220V here but with a multimeter my jack says that the energy that is coming is about 243... 245, should i be ok with that?

And there is a way to know if a PSU is working in a single or multi rail? I mean a viewable way?

Thanks again my friend

I was on the wrong thread sorry.

I was bouncing between different site forums and links ignore my post.

wsarahan · Mar 8, 2014

Why my friend?

wsarahan :

Like i already said,

Vic 40 :

Sextuple independent is multirail in this case.The sticker is right,the site gives contradicting info about it.

wsarahan :

Yes,at the site under the specs it says the following,

Full range input voltage: 90-264Vac

when it does go over one of the protections should kick in=ocp if i'm not mistaken..

wsarahan :

By you yourself? I don't think so.

In the end it doesn't matter as Someone Somewhere already pointed out,

Single vs Multi is a way overblown topic.

as in,it doesn't really matter.

wsarahan · Mar 8, 2014

Vic 40 :

Vick last question about the voltage, the site says 264, but take a look at the stick at the PSU

It says 240, that is way lower than the site, and the stick says the multiple lines as you already said

Now with the stick in hands, should i worry about here getting 245V or relax about it anyway?

thanks again man

Someone Somewhere · Mar 8, 2014

240V nominal. Generally your lines company considers it OK when it's inside 10% of the specced voltage. As some countries use 240V, and some places will have voltages above nominal, that makes it 264V max.
