actually, amusingly, I have the same issue

Bob

@Sathya that network is vastly more powerful than yours => it interferes with/'drowns out' your signal to an extent

allquixotic

but it shouldn't matter if they're on distinct channels

Bob

remember, this is a logarithmic scale

Sathya

oh

allquixotic

only one fairly weak signal is on channel 11

Bob

3:00 PM

that's something like 40 times more powerful, unless I'm reading it wrong o.O

Sathya

that n/w isn't available now..

Bob

@allquixotic ya, but at the moment it's overlapping

hence "try putting it on channel 11"

allquixotic

@Sathya it might be popping in and out

Sathya

@allquixotic ok

allquixotic

which might explain your intermittent problems

Sathya

3:01 PM

@allquixotic suppose it can be replaced. need to check.

Bob

seriously, there's something very wrong with that network :S

@Sathya how far away are you form your router in that screenshot? is it through walls?

allquixotic

@Sathya 5 GHz is much less likely to be interfered with, because things like microwaves, vacuum cleaners, bluetooth, Logitech Unifying, etc. all use 2.4 GHz and not 5 GHz

Bob

could we get a comparison right next to the router? i'm curious :P

Journeyman Geek

@Sathya: I had the very same issue

allquixotic

oh and Miracast

Journeyman Geek

3:03 PM

(though, the AP is unsecured, I could EASILY just turn down their TX power)

allquixotic

basically everyone and their mother is broadcasting signal and noise of varying protocols on 2.4

5 GHz is pretty much just WiFi at this point

Bob

@allquixotic look at that crazy spike in the graph on the right of the screenshot...

Sathya

@Bob yes, throw 2, 1ft walls. Router is approx 20ft away

Journeyman Geek

@allquixotic: annoyingly most if my n gear dosen't do 5 ghz

even my laptop

Bob

@allquixotic also, far more available channels

allquixotic

3:04 PM

@JourneymanGeek fortunately, the Surface Pro, the Droid Maxx, and my NUC are all dual band :D

Sathya

Bob

@allquixotic the dual-band chip in my laptop is preventing Win8.1 :(

Journeyman Geek

(my router is dualband however)

Bob

@Sathya look at that graph on the right - what's with all those massive spikes on your network? :(

Journeyman Geek

@Bob: interference

@Sathya: the android version of inssider is MUCH more useful for this sort of thing

Bob

3:06 PM

@JourneymanGeek ya, but from other wifi routers somehow broadcasting dozens of times stronger signals

presumably from further away, too

Sathya

@JourneymanGeek ah okay

well, moved to Ch 11

Journeyman Geek

(wevo is the korean router I was bitching about the other day)

Bob

also, that new version of inssider looks fancy :P

Sathya

Bob

I'm still on 2.1.6.1395

> The application is up to date

like hell it is

Sathya

3:10 PM

@Bob just downloaded yesterday

allquixotic

@Bob kinda like my Lenovo ThinkPad Tablet (Android slate) saying it was up to date when running Gingerbread, despite ICS being available by OTA

had to manually flash it

Bob

eh, it's a whole major version ahead

so much for up to date

they even changed the logo!

it's fairly quiet here

allquixotic

I was gonna say, -25 dBm in sathya's original screenshot seemed highly irregular

Journeyman Geek

yeah

allquixotic

like, to get -25 dBm in normal circumstances, you'd have to be physically touching the antenna of the router to the antenna of the wifi chip

Bob

3:17 PM

I operate all three networks at the top of that list... and they're overlapping -_-

allquixotic

@Bob brilliant! :D

Journeyman Geek

lol

I'd spread them out myself

Bob

@allquixotic well, the build of dd-wrt I was running previously was broken in a weird way

so when I finally got 40MHz to work i just stuck with it

Journeyman Geek

(I operate two networks, but they're on either side of... The Dead Zone)

Bob

I'll probably twiddle the channels some other time

Sathya

3:18 PM

@Bob lol @ network called Marathi

ProgrammerGirl

Hi guys, can someone help me with a PSU installation question, or am I in the wrong place?

allquixotic

40 MHz width always turns out badly for me

@Sathya why is that funny?

@ProgrammerGirl you're in the right place, but we're a little busy... as they say in hearthstone, "Busy night! Pull up a chair!"

Bob

@Sathya I have no idea who that is.

Sathya

dunno, just found it funny to named after a language /scratches head

ProgrammerGirl

It's just a quick question about a cable that goes into the GPU, if someone has a quick sec. =)

allquixotic

3:19 PM

@Sathya oh, it's a language? interesting

Journeyman Geek

@ProgrammerGirl: ahh

there's two types of those

allquixotic

@ProgrammerGirl go ahead and ask

Sathya

also, wrong in reply to

Journeyman Geek

IIRC 6 and 8

Journeyman Geek

8 pin is usually needed. If it needs more power then plug in the 6 pin @ProgrammerGirl

@ChatBotJohnCavil that;s a lot of commands bub

Bob

@JourneymanGeek uhh... my graphics card only takes the 6 pin ones :P

allquixotic

basically your PSU needs to have the plugs that the video card has holes for

Bob

so-called PCIe power connector

allquixotic

i believe 8-pins are for PCI-E 1.0 cards and 6-pins are for the newer revs

Journeyman Geek

or did I get them confused

allquixotic

3:21 PM

fewer pins, more punch... somehow

Bob

@allquixotic you can get molex => pcie adaptors, I think

allquixotic

@Bob yeah but isn't that a voltage conversion from 5V to 12V? :/

or is it 5V anyway

Journeyman Geek

lol

Bob

@allquixotic molex has both a +12V and +5V

and sometimes a +3.3V

allquixotic

ohh TIL

Journeyman Geek

3:22 PM

@ProgrammerGirl: what was your actual question? ;p

allquixotic

we go off on tangents sometimes

Bob

@allquixotic You do end up drawing more power from a single wire, though

allquixotic

soon we'll be debating electron flow

ProgrammerGirl

Great, thx. My GPU has 2 x 6-pin going into it. My PSU has either 2 separate 8-pin-to-6pin, or 1 8-pin-to-2-6-pin...do I use the 2 separate ones, or the single one that has to 6-pins on the end? How can 1 single one handle the same juice as 2 separate ones if the head connecting to the PSU's are the same on both? :(

Bob

so higher losses, inefficient, possible damage to the wire

Journeyman Geek

3:23 PM

ahh.

allquixotic

@ProgrammerGirl the two separate 8-to-6 should work fine

Bob

but in most cases it just works

Journeyman Geek

@ProgrammerGirl: they're connected to the same rail at the PSU

so don't worry about it

ProgrammerGirl

So I should use the 2 separate ones then?

Bob

@ProgrammerGirl what's a 8-to-6? o.O

@JourneymanGeek not always

allquixotic

3:23 PM

i've never seen a single 8-pin connector that splits out into two 6-pins

Bob

some PSUs have multiple +12V rails

allquixotic

@Bob it's an 8 with 2 pins that split off :P

Bob

@allquixotic oh, those things

be careful

they might not be a PCIe one

allquixotic

yeah, could be for the mobo :P

ProgrammerGirl

My PSU is a Seasonic 860W Platinum (if it helps)

allquixotic

3:24 PM

fully modular, nice

80+, niiiiice

ProgrammerGirl

The 2-in-1 cable says "PSU" on one head, and "PCI-E" on the two other heads.

allquixotic

quality brick there

Bob

@ProgrammerGirl that would probably work

though it's normally recommended to get them from different cables

that way you draw less current from a single wire

Journeyman Geek

wait

allquixotic

special features -- "high +12 V output"

Bob

3:25 PM

lower losses, less heating

Journeyman Geek

the 8 pins is at the PSU ?

its not a splitter really, then

allquixotic

seriously unless you're running like dual GTX TITANs, I wouldn't worry about the rail configuration on that high-end PSU

Journeyman Geek

so yeah, I still think its not an issue

allquixotic

just pick one of the two plugs and plug it into your GPU :)

it will work

Bob

@allquixotic again, be careful

allquixotic

3:26 PM

that is a seriously great PSU

ProgrammerGirl

Yes, the PSU head has 8 pins (if I look inside, only 7 have metal in them). I'm talking about the 2-in-1 cable.

Bob

there are connectors with the same number of pins with different pinouts

brb searching for a diagram

ProgrammerGirl

On the single cables, the 8-pin PSU head only has 6 holes with metal in them...

allquixotic

@Bob the one that goes into the mobo is 8 pins, and both her GPU plugs are 6-pin, so they wouldn't be physically compatible

ProgrammerGirl

The GPU head of the cables are all also 8-pin, but I say 6-pin because that's what my GPU needs.

allquixotic

3:27 PM

i think her modular PSU just gave her two different ways to produce 8- or 6-pin PCIE plugs

Journeyman Geek

yup

Bob

here's a good guide: moddiy.com/pages/Power-Supply-Connectors-%26-Pinouts.html

Journeyman Geek

makes sense tho

allquixotic

makes good sense

Bob

you might have the "6+2 Pin PCI Express (PCIe) Power Cable Connector", a little over halfway down the page

allquixotic

3:27 PM

that PSU can probably support two high-end GPUs in SLI/CF

Journeyman Geek

nearly everything breaks out from the 4 pin connectors on my m12

Bob

confirm by matching up the wire colours and locations...

allquixotic

@Bob meh. if the cable has "PCIE" printed on it as she says it does, no need

ProgrammerGirl

All my cables are "black". ALL OF THEM. Doesn't help... :(

Journeyman Geek

lol

Bob

3:28 PM

@ProgrammerGirl O_O

Journeyman Geek

@Bob: thats normal

allquixotic

normal for modular :)

Bob

@JourneymanGeek black heatshrink bundles, sure

but black wires is weird

ProgrammerGirl

So basically, the only difference btw the individual cables and the 2-in-1, is that the PSU end of the 2-in-1 has 7 metal holes, and the individual ones have 6. How can just 1 extra metal hole provide twice the juice?

allquixotic

@Bob here's why I don't think she has any possibility of error. the 8-pin motherboard connector is this, and that's the only potential physically compatible connector that would fit in a GPU external power socket... BUT... hers are all 6-pin, so it wouldn't fit at all.

if her GPU had 8-pin PCIE connectors she'd have to "be careful"

as it stands there's basically no way she can go wrong

unless she tries to jam an 8-pin connector (with no 2-pin split-off) onto a 6-pin socket o_O

Bob

3:31 PM

@ProgrammerGirl you split off wires in parallel, which are at the same voltage

allquixotic

@ProgrammerGirl if the individual cables connect separately to the PSU, they could also in theory be using different +12V rails

ProgrammerGirl

OK, so should I just use the 2-in-1 to minimize clutter?

Bob

but it's normally recommended to plug the GPU into two separate cables all the way to the PSU to minimise losses in the cable (higher current => higher losses)

personally, I just used two on the same cable

allquixotic

the 2-in-1 could be using the same rail, depending on the layout of the rails as they map to the holes in the modular supply interface

Bob

@allquixotic almost definitely if there's only one extra pin on the PSU side

allquixotic

3:33 PM

the risk being that overloading one rail when you have more than one rail could potentially put undue current through that rail

ProgrammerGirl

Both the individual cables and the 2-in-1 have the same 8-pin PSU head, with the difference being an extra pin with metal in the 2-in-1.

allquixotic

so you would need to use a lot more holes in the modular interface for the two separate connectors than the 2-in-1

that's certainly a downside, if you have lots of stuff

Bob

@ProgrammerGirl without tracing wires, it's impossible to be certain what that does

allquixotic

what GPU out of curiosity?

ProgrammerGirl

@allquixotic: correct, that's why I'm not sure what to do.

I don't want to fry my GPU or PC, but I also don't want extra cables if I don't need them...

GPU is a Radeon 7950

allquixotic

3:35 PM

I really wouldn't worry about it -- unless you are overclocking and stress testing that in worst case conditions, you aren't going to come near TDP in most cases, and the wires should be built to withstand even that worst case scenario

the 2-in-1 should be fine (*)

Bob

@allquixotic could stress test it and feel the cable

if the cable doesn't feel hot, you're probably fine

allquixotic

I mean, this is a very, very good PSU -- there has to be a lot of margin in that stuff

if this were a cheapie I'd hesitate

Bob

heh

I wuoldn't worry about the PSU side

it's the cable itself I'd be a little more concerned about

allquixotic

@Bob if the cable is manufactured by Seasonic (it'd have to be, to fit in the modular PSU), it's probably just as good as the PSU itself :P

which from the looks of it, is top notch

@ProgrammerGirl I think the verdict is, if you have enough spare holes in the modular interface on the PSU to use the individual cables, it's safer in theory to use the separate cables, but on the other hand, if you need the holes for peripherals, fans, etc, then I see no reasonable reason to be concerned about safety or reliability by using the 2-in-1

they wouldn't have given you a 2-in-1 cable labeled PCIE if they didn't expect you to use it with a gaming graphics card

ProgrammerGirl

OK, sounds fair. I have spare holes, so I'll go with the safer bet then.

allquixotic

3:39 PM

and Seasonic doesn't seem like the kind of company to do something really stupid and inadvisable like give the consumer a plug that would catch on fire

ProgrammerGirl

If I end up crossfiring in the future and need more holes, I'll use the 2-in-1's...

allquixotic

yeah

@ProgrammerGirl Welcome to the Root Access chat for Super Users! Please don't ask if you can ask or if anyone's around; just ask your question, and if anyone's free and interested they'll help.

allquixotic

:p

our bot likes to welcome people, but he doesn't get to do that very often anymore

ProgrammerGirl

It just really threw me off that the ONLY diff btw the 2 was an extra metal connector. Anyway, thanks for all your help, guys. You're awesome! =)

allquixotic

3:43 PM

until today I'd never even heard of Seasonic

that's very odd considering how good the product appears to be

do tell us if you have problems with this PSU; your silence will be interpreted as an implicit endorsement ;-)

usually I expect this type of rugged quality from Corsair, but maybe Seasonic is just as good

Darth Android

I've not used a seasonic, but I've also heard very good things about them

allquixotic

looks like they are a PSU-only shop, but they also happen to sell a gaming keyboard

being a PSU specialist is a pretty nice thing though, shows that they are focused on capturing market share in that area

Journeyman Geek

lol

allquixotic

here's another indicator of quality: here -- $239.99 USD... for a PSU, that's pretty expensive

Journeyman Geek

I like their PSUs myself

allquixotic

3:47 PM

cost != quality always, but it's certainly at least weakly correlated :P

> +12V@83A

never seen a 12V rail that high amperage lol

Bob

@allquixotic some fancy mech-rubberdome hybrid switch :\

that's 1500W...

@allquixotic whatf

allquixotic

@Bob huh? 12*83 = 996

Bob

@allquixotic whoops, must've been a typo somewhere

ok, now I'm on channel 11 + 7

and it actually works

allquixotic

although, if you took all 83 Amps on the 12V rail, that leaves 4 Watts for the rest of the rails :D

that's pretty funny :D I guess it can go a little past 1000W though, wouldn't surprise me
