    OK, I've had some fun checking out video card power consumption:
    Report: the true power consumption of 73 graphics cards - BeHardware
    BeHardware includes a chart comparing power consumption via the PCI-E slot.
    Power Consumption of Contemporary Graphics Accelerators: Spring 2010 - XbitLabs

    Product survey: 7 power supplies for less than 45 Euros - page 7 includes a review of the Heden 500 watt psu.
    I hope your drooling doesn't result in crying tears.

    The enclosed charts are from the BeHardware article.
    Download and zoom in to read the numbers, they will be readable.

    Chuckle ,
    Yeh PJ ,Actually my mistake on the psu the pos one I bought was also from pixmania ,but they have 2 different branded crap psu's in their range.The one I bought was was the advance 480w model to exactly use up the amount of credit i had left.
    Rest assured tho Im sure it s performance under testing would be equally crap.

    The gx card charts are interesting for the pci slot draw too even tho mine isnt on it ,but the slot power draw does seem to vary a lot.However thx to your link I did find my exact gx card power consumption under load(at out of the box clocks).
    gainward gs.
    This is a little more optimistic and along the lines of my original estimates in that 400w 12v output should be sufficient for the system on my "good" psu but on the edge if overclocking hard (the gx card).
    Assuming the rails are balanced of course.
    If there is some 50+ w running around "free" on the 12v side,id like to tap into it,
    for "small bucks"tho .

    1.Its strange the price of the connectors I need to do that when u include p+p amount to 30% of the price of a more expensive option and with no guarantee of success.
    I would be interested to know how the EPS 12v supply to the mbrd is distributed on board.I know the cpu wont work without it ,but has Gig directed all of that input to the cpu or is some distributed around the board depending on load.
    (that is beyond the scope of this article )

    As I said before my current psu is good imho...
    As it is, from the more definititive information u guys have supplied .

    I can hold my 500/2000 fsb overclock and leave the gx card as it arrived out of the box.(700/900)full test
    I can run at 490/1960 and run gx at (800/1000).full test
    However as its set right now anything higher on gx or cpu in combination leaves me with nothing to spare on load.


    Further to your earlier suggestion PJ, of the cheap psu for the fans.You meant an external 12v one yes?. with wires running to the interior of the case?

    What about Lian Li Dual Power Supply Adapter Cable - FrozenCPU.com

    I think I may have an old at power supply around somewhere.Once again tho $15 is $15 and having a psu running at low load just to power a few fans would be very inefficient and messy wiring.
    Anyway back to price scanning ,before I go crazy and spend the huge $10-$40!

    My el cheapo, mickey mouse idea was to use a 2 - 3 amp A.C. adapter similar to what comes with a digital camera, external hard drive, etc. I'd have no qualms slicing and dicing the AC adapter's 12 volt output wires for multiple 3-pin fan connectors, something like this one, where it would only power your cooling fans.

    **edit** I think that that ATX_12V (4-pin) and EPS_12v (8-pin) connectors provide power ONLY for the cpu.
    I'm reasonably (OK, somewhat) sure that the 12 volt wires on the 24-pin main psu connector provide the remaining 12 volt power to the rest of the motherboard.

    The Lian Li Dual Power Supply Adapter Cable - FrozenCPU.com that you asked about should work with a secondary psu, as long as there's enough electrical load on the 2nd psu. Some power supplies might have problems with an electrical load that is to low.

    OK, I did some checking and I'm positive that I'm correct about the ATX12V and EPS12V connectors, in fact, I'm willing to bet your life that I'm right.

    The following links from PlayTool.com cover most of the basics about power supplies:

    Default Re: EP45-UD3 power distribution opinions.

    Yeh i had been into that selection of links before.

    Seems to me the single rail 12v supply if it is rated high enough and is wired correctly has no disadavantages over a multi rail 12v system.
    Its only in the last couple of years that multi rail 12v have been allowed to have one of the rails in excess of 18a rating

    There are other factors ,theres no denying the gx card pumps a lot of heat into the pc case when its used hard and with limited fans everything gets hot compared to my previous setup .The airflow (visual guess )looks like 80% of the heat into the case and 20% out the back .thru a partially obscured pci vent.
    Im not going to mess with the gx card airlow directly .
    but thas another story.

    Extreme conditions : reviews show i have nothing much to spare on power supply for cooling .(fans)
    My mch temps now reach 44-45c,maximum i ever had before(without failure) was 42c ,but that probably shows my positioning of the sensor isnt close enough to the core(more of a heatink reading) and readout is affected more by case interior heat.

    System temp is much higher also which actually gets nb/memory fan up to speed , but once again that increases power load.
    Another consideration is the heat going out thru the psu.
    If it gets hot ,its efficiency/power output/stability will drop off etc.


    I could be happy with
    (a)no gx card overclock beyond 800gpu/1000 mem,max fsb 1960.
    I think the maximum power drain from gx is about 30% more than my previous card at heavy load.The problem is headroom.

    (b)I mentioned a cheap 750w modular psu awhile back ,actually its a lower rated version of Wazza's psu..http://www.advancetec.co.uk/acatalog...t_modular.html
    I mean the manufacturers may overstate capabilities a bit ,but if you factor that in buying 1000w rated for $70 might be within limits for its lifetime compared to say a 750w rated $150 unit,you could be ok.

    (c)Im so close as it is(mho) ill try one cable change tomorrow.
    If that doesnt work out ill buy the $45 750w(pos or otherwise).My present psu cost $80 equivalent.

    There is no "balance your 2x 12v rails to get max amperage spread" device so unless this StarTech.com 4 Pin to 8 Pin EPS Power with LP4 Cable: Amazon.co.uk: Computers & Accessories
    in conjuction with another cable works: ill hold as is or go the new cheap psu,but hopefully better route.

    edit:
    Option (c) (rail balancing ,drawing some possible power from 12v2)above made no appreciable difference
    Do remember tho ,this is test hard! occt psu is linpac and gpu test combined.
    I tried simulating the same thing with kombustor and occt regular and kombustor and linpac(occt) but i didnt get the same "kill your pc" strain.

    However
    "on the limit " or max power/heat 490 fsb with the gx card above 800mhz gpu ,1000mhz mem produced graphs /results/ripple much closer to atx limits than my old card ever did.
    Id produce loads of comparison screenies ,but hey Im not getting paid for this :0

    500fsb/4ghz cpu and 800 gpu/1000gx mem produce "duck quack" under test after 20 min.related to power and insufficient heat disappation(mho)
    things like fewer fans,mem sticks on 2.2 v instead of 2.1 well over 5w per stick etc.

    ..Other thoughts
    Cheap 750w psu with all the connects.. yeh ive already loaded up the credit for it.. but may not buy it.What if its a 500w branded optimistically(shafted)

    Dual or triple psu,I have my normal psu,I have http://www.pixmania.ie/ie/uk/569892/...er-supply.html actually rated 18a on 12v1 and 12v2(probably 20A max single rail, heh when u load it).I also have a couple of single rail at units rated 9 and 8a.
    The thing is now we "have to" buy 1000w psu to get rails for the gx card(s). Especially if going sli xfire.

    If you have a big enough case you can fire up additional psu's and just have them power the gx cards. The only thing is to have only one psu connected to the mbrd.The others can power the sli gx cards.
    All you need is a 12amp rated 12v supply per gx card.
    the 80% efficiency thing . even the crappier ones get that at low load anyway, so we dont have to worry about saving the planet.

    My r2 case is "cool" tho .i think in a not like all the others way,but another psu in there.. forget it.

    Default Re: EP45-UD3 power distribution opinions.

    tested a
    jeantech 250w psu(single 12v rail 15a)in conjunction with my
    jeantech 500w psu(dual 12v 18+18a) and the dual psu setup seems to be working well.

    The 24w(rescued from a dell) 92mm fan seems to be really good .
    Its a self speed regulated one ,as 2 of my 80mm 4 w fans are .
    it is a "mini tank" tho as you would expect from the power consumption rating

    When its pushed (exhaust temperature gets high) it speeds up(max speed around 5500 rpm) and the noise increases its nothing annoying tho.

    250 w psu is powering the 2 ,6 pin pcie gx card connectors and the 24w fan.
    It seems good.for now full load. there is a lot of air being moved.

    Of course the second psu will have to exhaust vertically out of the case and I will have to break down the whole pc for cutting and drilling..
    metal shavings floating around inside a pc arent good..
    Should have it completed this week.there is hardly room inside the case for anything else ,but the testing is so good I dont care.

    No you don't. Multiple rails is a pointlwess waste of time. A single rail PSU is all you need. And you certainly don't "need" 1KW for anything but two GTX 480's or QuadFire. You could SLI two 460's on my system and be more than comfortable with a HX 650. Multi rail PSU's are used either to comply with an outdated health and safety standard or because nieve people think multiple rails are "better" or "more stable", which is rubbish.

    Throw this pile of sh1te in the bin. You can't even get a decent premium 120mm/140mm fan for 17 euro. a 15A 12V rail means it can only output 180W on that line, and IMO that'd be pushing it. The only time I'd use that PSU is if I really didn't like a person I was building a PC for and wanted to set their house on fire.

    Also be ware of using that 250W psu as a 12V only supply. 99.999% of PSU's REALLY don't like supplying 12V with zero load on the 3.3 and 5V rails. They hate it so much it can cause them to blow.

    From the sounds of it, I really wouldn't leave your PC on unattended as what you're doing is extremely dodgy, especially with your choice of cheap-ass PSU's. Invest in a fire extinguisher...

    There are no multiple 12v rail psu's not really.
    There may be some server type psu's with independent 12v rails.
    For most of us were encouraged to buy the ooh multiple rail 1000w psu ,which is actually
    a "single 12v rail" with current limited outputs.
    For the newer power hungry gx card's at least.
    I think I expressed further back my preference for a "single rail" psu I dont have one so Ive worked on other options .
    Even on single 12v hi amp output rated psu's the connections have to be there and spread correctly.

    Some psu's require a minimum load on 3.3v and 5v outputs,some dont.
    Minimal research will confirm that.
    You can run fans or apply a resistance across the outputs of a second psu lower voltage outputs if you feel the need.
    There are whats termed "supplemental" psu's sold ,which are in essence a second psu wired up to start with the "main psu"..
    Some even have very hi amp/wattage ratings.
    Hah and yeh current limited "multi rail" like 650w and 20+ amp per 12v rail
    Mainly on the 12v output,,since they are really sold as "pci express 6/8 pin additional" power units.

    They dont include any sophisticated feedback.
    They are basically hog units for connecting to 6/8 pin connectors or 5v external items.
    In other words they are a second psu inside your pc,just not connected to the 24 pin mbrd atx supply.
    The price of these items tho is close to what is termed a "good" full 600 w psu.
    Considerably short of the cost tho of a ,you gotta buy me cos im the company flagship 1000-1200w psu.

    Recent testing has included an old at psu (maximum total 12v output 8 amp)
    jeantech 250w,180w constant on 12v)
    advance 480w (supposedly 18a 12v1,18a 12v2)
    and original 500w psu.

    New case .well actually an old type case
    rascom.at - Willkommen
    will be appearing soon with
    rascom.at - Willkommen
    and
    rascom.at - Willkommen

    The case ,mainly because it over 20 cm wide(heatsink clearance) and provides good filter options.
    The other items,because they were dirt cheap.
    I still have to determine the best drilling site/location for secondary psu/psu's.
    250 w one mounted with the exhaust fan venting out of the case top looks promising,but im not 100% sure and will need to be before the "case cut" even tho case cost is like $20.
    The best ripple and voltage variation havs been with the jeantech 250w additional psu even with the 24w/2.0 amp fan.

    In short gimme some more + feedback/advice, as I progress,like Pro J.
    Wavey arms in the air and call the firebrigade.its possible yeh but just an opinion.
    Independent 12 v rail psu's are supposedly the best.How that determined I dont know since there seems to be very few in existence.
    Dual or triple psu,(if you need it)should provide the same thing,provided you have the case room and the wiring doesnt get like spaghetti junction.

    Default Re: EP45-UD3 power distribution opinions.

    Best advice is to dump both low end power supplies and buy a decent high quality unit.
    A modern "multi" rail setup will work equally well, if the built-in protections are implemented correctly.

    On the Antec website, all/most of their models have OCP set significantly higher than the maximum rated current for each rail. All of the TruePower New models (550, 650, 750) have OCP set at 40 amps per rail. I'm not loosing any sleep that my TP-750 has "trapped" power on any of it's 25 amp rails.

    From Jonnyguru.com - NZXT Hale90 850W psu review
    (marketing features)
    • Strong Single Rail Design: A single +12V rail provides stability and ease of use making the most out of your power supply. Offers stable & clean current delivery under heavy load.

    -Sigh... another one falls to the single 12V hoopla. While it is true that some old units did multi-rail overcurrent protection all wrong, for the most part we no longer need to worry about this. Unless you are Peter Peltier with the peck of powered pelts or Howie Hard-Drive with the hankering for hundreds of hexabytes, there simply is no advantage one way or the other to which design you choose. Unless you're looking at something with a single massive 100A 12V rail or something... then you're starting to run into a "maybe it will, maybe it won't shut down in time to save this computer on a partial short circuit" issue.
