    AW 17 240W PSU adequate?

    Hello,

    I am in final stages to make a purchase of an AW17 and was wondering if the stock supplied brick of 240W is enough for maximum performance at stock levels (no oc) as some research brought into my attention that most people try modding for a 330w even in m17x models..So I'm not sure if I'd also need that so I could plan accordingly.
    The config mainly has:
    GPU: Single Nvidia 880M
    Proc: Intel 4710mq (could possibly upgrade to a 4900mq factory OC)
    Ram: 32GB
    HDD: 256Gb ssd +1tb hdd
    Display: 3D 120hz

    On a sidenote: Any advise that if this machine is costing same as an AW18 with CFX R9 M290X, 16GB lesser Ram and a better cpu (4810mq), which machine would be a better deal considering they are more or less the same price?
    I would have to let go of the 3D display and nvidia gfx in return for an xfire r9 m290x setup and no 3d display and possibly bigger footprint etc and a SLi 880M would add like $700 to the price difference.
    But just need a general idea what the community thinks about this if a single nvidia gpu 880m is worth it against an xfire setup or if the $700 more is worth it?

    Thanks. Regards

    Yes is enough, your sistem without overlock drowns 215W max....your psu is 240W. So if you dont do extreme oc it will be enough

    Also if the cpu is upgraded to a 4900mq which is factory overclocked 3.0/4.0 it is still stable with the psu they provide?
    Ofcourse the system would have warranty and I'm assuming they are giving an overclocked cpu with an 880m and a 240w psu it should be fine?
    thanks

    4900 is 47w and 4710 is also 47w so they consum the same amount of W, if you overclock it and the card burns and they find out somehow that you overlock it you can say bye bye to your waranty

    Actually it is overclocked from them by default upon purchase if i wish to purchase an overclocked 4910mq. So if in that case something goes wrong its on them cause they sold an overclocked upgrade with the initial config? I'm not sure how much an oc 4910mq would utilize if its oc'd to be at 3.0 normal and 4.0 turbo freq. And in which case would the 240W supply provided by them still be enough? I'm hoping they do know themselves the power supply they are providing is to be enough to run a processor they are selling at an overclocked level?

    Remember that many of the modders do have R2's. We have dual GPU and need more than 240.
    If we overclock the GPU's and the CPU's we also often need more than the 330 can give to.

    Reading this towards the end:

    We see drawbacks primarily in the weight and noise production. It is also upsetting that the GTX 880M lowers its clock during full load (should not happen in gaming routine). Apart from that, the XMG P704 is a very good and individually configurable gaming laptop.

    Isnt reducing clocks also reducing power consumption? Changing VBIOS to stop the lower the clock should increase the top current i would guess?
    But still it should perhaps be more than enough using the 240 that normally can deliver way above 240.

    That pretty much explains it, I was worried if the AW17 (which I doubt even has SLi/CFX capability for future) would run into a power issue by running the 880M under powering it or under powering the 4900mq cpu using a 240W brick.

    So from my understanding the 240W is fine and won't be reducing clocks of 880M and a [email protected]?

    Yes it will be fine. I have a 240W brick and with my 3940XM at 4.1GHz and my 7970M at 1050/1450 (stock is 850/1250) I was able to complete 3D mark 11 benchmark halfway through before I ran out of juice.. I wouldn't have that issue if I had a 330W brick. Your not going to be doing any such mad OC like that so 240W will be enough..

    Yes I won't be doing any oc, the intel chip 4900mq is factory oc'd at 3.0 (4.0 turbo) upon ordering

    Well even more reason not to worry.. My chip was running at 4.1GHz.. Just ran intel stress test and my CPU was pulling 63W...So even with Haswell being more inefficient than Ivy Bridge, your never going to reach 57W let alone 60W :D

    I had just tested my Alienware 17 it has an overclocked i7 4930mx. Tested machine with the new test skywalker in 3dmark. My wall-mounted power meter showed a consumption of about 249 watts under this new test. Remember Hotwell processor uses much more watts than the old versions of the i7. I have a little Overclock on my gpu at 78/200 (849/1450) with the original VBIOS. If I use a modified VBIOS on gpu, and clock my cpu higher, I now have no choice other than and buy new 330W power supply.:thumbsup:

    Yeah, an overclocked Haswell is definitely a huge power hog.

    Just grab yourself a 330W PSU for home use. Use the 240W for travel.

    The best of both worlds.

    Amazing at 3.7ghz- 4ghz my overvolted 920xm pulls more than 150w haha

    Now there is a real power problem for you lol

    I just hope that your motherboard doesn't fail due to such a power draw.. That's almost 4 times what the CPU is supposed to draw...

    You are not familiar with the 920xm I guess. Just stock it can pull over 100w by itself.

    I am pushing things a little sure. Luckily the m15x is a tough cookie.

    Wow.. Didn't know that.. Its a bit wrong considering Intel lists the stock TDP as 55W... Bloody Hell.. Well gl and hopefully your M15x stays alive ;)

    Yeah hopefully. I might even overvolt it some more haha!!

    Tdp doesn't translate directly to power in wattage used. It is more towards thermal wattage. According to throttle stop thermally Iam at just 87w tdp lol the higher the over clock the more heat the higher tdp to remain stable without throttle unless you modify your cooling accordingly.

    Sitting close behind a 4700mq in pass mark however gives me great satisfaction and in winter I can do it while simultaneously heating my living room. Pretty fantastic ;D

    Have you done a 1024 test in T-stop?
    If so, what is the score you get?
    I get just below 400s stock voltage 26X and 5% in BIOS.
    Clocks then hover around 3650 max.
    You will thrash that score. :)

    28x is only 3724mhz so not much higher than your 26x plus 5% BCLK OC. The scores translate as such. So far out of 2 runs my best is 390.24 secs. 29x might be stable for TSbench though although it isn't for prime 95 nor video encoding so for me I don't really care to test it. Unless you want me to of course :D

    Then again I may just bump up my own BCLK. At 140mhz I should be up to 3920mhz lol. I will let you know how that goes...lol

    Ive never been able to run overvolted on my CPU with those clocks for the entire 1024.
    The temp increases and throttling is result, the higher voltages would need outside temps to be very low.
    I run it stock voltage. :)
    Best run: 397.
    Ive reduced the speed now. Seems it snags every now and then when doing BF4 so now im running 25X and 3% since it seems enough.

    I do howevver have a 940 CPU that I was able to run harder. That one did the 32 test with 4K clocks.
    Since i use heatspring now, im not going to disassemble for running with the 940, the 920 is way better at stock voltage than the 940. (the 940 has a damage, and my 920 is extremely good compared to most others)

    Fair enough. I can run 3.73ghz 1024 and temps don't reach 90C. Video encoding pushes temps towards 95C. Ambient temp around 26C. Japan is warm.
    I guess my 920xm ain't a bad chip! In winter I might add another 50mv on top of the 160mv already overvolted and aim for 3.9ghz across all cores :D
