    Default Super flower golden green 750W help

    Hey guys, I have this PSU (its the non modular version, can't find link to it on its website, its named the same as the modular)
    http://www.super-flower.de/index.php?id=97

    I'm a bit of a newbie about PSUs and I wish to know what is the max continous power it can take safely from the wall, I use it for VGA cards only (+sempron 145). I have a wattmeter attached to it, could it take 700W from videocards and the rest for the cpu+mobo?

    The 800W version was reviewed here and it says 88% eff on max load, this psu should be similar, does that mean it can take 850W~ (*.88 = 748W) and use 748W in the system or it can take 700W and use 616W ?

    thank you!

    yes, the wattage rating is dc...what it can supply the system.

    What you measure going in (AC) will be higher as you calculated.

    750W, maybe a bit more, before protections kick in.

    Power from the wall accounts also for losses due to conversion within PSU, which are not load. 750W is the max load.

    thanks for replies.
    So what you guys think, how long can it power 700W~ 24/7 ?
    Also I kinda need some help with molex cables. A molex can supply 60W on a +12v single cable, but from the PSU, at least 4molex cables are in serial, so if I plug 4 of them, can they supply 240W all together ? I don't know what kind of cables are in the molexes that are connected one to another.

    For the warranty period, certainly. Overall I'd expect good several years from it.

    This PSU already has 4x PCI-E, what sort of monstrous GPU configuration is this supposed to power up (actually this should be asked first)?

    Let me guess, BTC mining?

    Would have to be Litecoin or something else - Bitcoin mining without specialized hardware these days is a giant waste of time.

    Yep, but it doesn't mean some folks won't still bother . I had people trying to build dual 280x rigs 2 weeks ago on other board for BTC mining. When pointed out profitability is questionable at best, they just said "whatever, I'll do it anyway and sell cards if it really turns out that way".

    yes ofc for scrypt mining, you gotta be braindead to mine btc with gpu
    Here's the stuff I want to do.
    Have 3 280x right now, I can undervolt them and right now 2 uses 550W and it will be about 750W for 3. (waiting for risers, they are in the socket now)
    But the psu has only 4pcie connectors, was thinking about using 2molex to 1pcie but I dont know how much they can take, normally it should be impossible to give 150W or even 75W from a molex that is classified as 60W. So the cables in serial (3-4molex on one big cable) how much they can supply safely?
    its either this, or I hookup another 750W (i have already) to 1x card and wait for the next card. dont wanna go for 5-6 card/rig.
    what rig you have wolf?
