  • Good morning mga sirs. Do anyone of you tried to use Cooler Mater V650S? Ive seen little reviews of this "wonderful psu unit" but I want to personally hear from the master's of this thread how effective this psu in real-world use. I am planning to build a gaming rig with the following specifications:
    Core i5 4570
    Gigabyte G1 Sniper B5
    Gskill 2x4gb DDR3 1866 CL8
    Samsung 120gb EVO
    Wester Digital Blue 1TB
    Noctua NH-U12P SE2
    2 High Performing 140mm case fans (Cougar/Corsair AF14)
    3 Corsair SP120 High Performance Ed
    XFX R9 270X/Sapphire R7 265

    Thanks po! Hoping for your immediate response.
  • Hello Guys. may Problem ako..

    I recently upgraded from this system spec:

    Athlon ii x2
    Am2+ asus board
    1gb ddr2 ram
    160gb HDD
    1Tb HDD
    1ODD
    asus r9 280x dcu ii top v2
    Antec True Power New 750w(bought and used since 2011)

    to this

    amd apu 7850k
    asrock fm2+ extreme 6+
    8gb ddr3 2133 cl9 dual channel
    2Tb SSHD seagate
    1Tb HDD
    1ODD
    asus r9 280x dcu ii top v2
    Antec True Power New 750w(bought and used since 2011)

    The bold ones are from the Old System.

    I came into problems like frequent restarts and grounding. I fixed that. now, ok na may OS na yung new rig ko. Kaso every 5-10 mins it restarts.. turns off and on again. wala naman BSOD.. so ibig sabihin hndi hardware failure(like RAM or HDD or Video card).

    I suspect that the culprit is the PSU.. parang di nya na kaya yuing system ko..
    kahit naka safe mode ako ganun padin eh.

    What you think guys?

    Please help me.

    Thanks!

    Update.. Changed my PSU to a CM V1000.. Still having the random restart issue..
    Assume lang natin na psu sya mainly considering the point na nagrarandom shutdown sya kahit sa safe mode pa lang. Kung ganun, dapat sa normal mode, magpopower cycle sya immediately dahil ganun na nga kababa yung output nya. Presumably, di na dapat sya makakapasok sa windows dahil pag check pa lang ni OS dun sa video driver nya, magshushutdown na sya. Di na sya mag-aantay pa ng 10min or so. What do you guys think?
    Right now we can eliminate yung about sa PSU Issue sit... kasi nag upgrade nako.. still having the issue...
    Tried Reseating the RAMS..Ganun padin..
    Mobo Issue na kaya ito?
  • @ rhumbutler

    are you going to upgrade graphics card in the future? if no, 650w waaay is too much for your rig.

    to answer your question, V650S is a good unit, with great voltage regulation. I would recommend that if you want to buy it, but I still prefer a seasonic branded PSU because of their awesome warranty length, not to mention its distro is awesome as well. not sure kung sino distro ng CM dito haha at alam ko 3 years lang ata distro warranty nyan, or maybe less.


    @ tuklap

    try mo yung magic linis ng ram contacts using eraser baka umayos xD

    run mo RAMs using memtest86+ and leave it for at least 6-8 hours per stick, pwede din dalawang stick sabay though. kung sa first 6 tests (actually first 3 tests lang) madaming error na lumabas, ram yan. otherwise, baka motherboard nga. unless lemon din yung V1000 (wag naman sana) which is malabo mangyari, but possible.

    also, pwede mo itry ilabas yung buong pc sa loob ng case, baka iba behavior nya pag lahat nasa labas. pag wala problema pag nasa labas, baka nasa case or wiring yan.

    ipatong mo na lang yung motherboard sa box nya to avoid grounding issues.
  • @Dyaems Thank you fpr your response. For the graphics card, I am choosing between those two mentioned cards and MSI gtx 750Ti. I guess overkill nga ang CM V650s. So I will buy (most probably with 80 chance) seasonic g550. With lots of good reviews and capable of powering my rig (and its more than enough I suppose), seasonic g550 will be the best buy. 80+ gold pa kaya power efficient. I am not planning to upgrade my grahics card probably for my next rig which i think 4 to 5 yrs from now. LOL. Thanks ulit. Truly, seasonic is the monster psu these days.
  • you can also go with Antec Earthwatts Platinum 450w if you want a cheap alternative from G550. 450w is pretty much more than enough for the specs you're using. Di nga lang siya modular.

    G550 is a good choice as well, kung may budget naman, why not diba :D

    a little bit of a trivia, ang Seasonic sa china at taiwan ay lifetime repair warranty, 5-7 year replacement depende sa model. grabe!

    Will try the magic linis eraser later(sana gumana).. if not.. will use memtest86+..
    weird lang kasi nung una, akala ko PSU. nag upgrade ako to 1000w tapos ganun padin akala ko mawala na.. meaning hndi nga dun sa psu problema...ngayong lang talaga ako nag ka problema about this build sa lahat ng nabuo ko na pc. ito lang talaga. iniisip ko na baka yung SSHD ko problema pero malabo din naman..

    GPU seems fine naman..burn test using mining pero ok naman wala naman issue...

    which narrows down to Mobo, RAM and APU(7850k)(baka nag ooverheat, using stock HSF)... lugi nako sa PC na yun.. di ko magamit ng ayos.. lagi restart..
  • @Dyaems being modular is really a big factor for me in choosing my psu. Ive read a lot about Antec Earthwatts. Medyo hindi kasing efficient ng seasonic g550. In the long run efficiency is important ksi tipid sa electricity :)). So mababawi din namn eventually. I think sa mga rig, psu is one of the most important factor to consider. In fact im looking for seasonic x560 kaya lang parang wala dito. Hehehe. Im not sure about this but I think cm v650s uses seasonic oem with added freebies kaya siya higly efficient.
  • platinum efficiency ang earthwatts platinum, kaya nga platinum eh. hinde yan bronze haha

    v650s is not a seasonic psu, enhance electronics oem nyan. yung mga walang S like V700 or V1000, yun ang seasonic based psu
  • Ah ok. Akala ko seasonic sya. Thats the point for antec ea. Platinum sya but not as efficient as others. I think mas ok pa ang fsp aurum 92+ compare to antec ea. Medyo mahal lang ng konti. :))
  • you cant get everything with a 2800 pesos psu lol. still better price/efficiency for 2800 pesos range psu. again, if you have the budget, go for the expensive ones. its your money and no point debating this one. im just suggesting another option lol

    EDIT earthwatts platinum is based on FSP aurum at nireplaced ata ang few caps para maging platinum if im not mistaken :P

  • Thanks for the suggestions. Yes i completely agree with you. Afted some research, for a gaming rig, it doesnt ,
    Make much difference with bronze vs gold. In fact halos wala or i significant. Hahaha. Im stil. Looking for a psu with high value for money that is modular. And at this point my reference psu is seasonic m12ii 520w. Not the cheapest but great performer.
  • i say get seasonic para lang sa 5 year warranty specially kung may budget naman. nagpalit ka na ng computer, may warranty padin yung psu mo haha

    meron din naman effect yung efficiency kahit gaming, pero matagal pa ata para mabawi yung extra cost na binayaran ng gold compared to bronze. may rough calculation yun dati sa isang thread dito e. G550 vs S12II ata yun xD
  • Ah tlaga. Wow! Saka mas powerful ang g550 ksi single rail lng sya unlike m12ii na dual rail for 12v. Sabi dito sa thread, mas magnda ang single 12v rail
  • observed this system for multitasking:
    Biostar G41D3+
    E8300
    1x4GB @ 533MHz (7-7-7-20)
    ST250DM000-1BC141
    Samsung SH-224BB

    powered by:
    Huntkey Stone 500

    with connecting components:
    -one USB webcam
    -standard mouse + keyboard
    -Hanns.G HH181 (1366x768@60Hz)

    along with (in a Huntkey surge protector):
    -a DSL-Wifi modem
    -a 4-port routerExternal Image
    actually pilit lang etong load (four 1280x720 MMORPG windows, VLC movie, iTunes, browser window with several active tabs, widgets, etc.) pero pag naka-minimize lahat (Show Desktop) eh naglalaro lang sa 89w

    special mention to sirs Helly and Dyaems (alam na ü)

    P.S.
    open nyo na lang link sa new window/tab kung fail to load man. di kasi makita rito, intermittent kasi net. pagpasensyahan nyo na screenshot ko.
  • @all

    fixed the problem.. it's not the gpu, mobo or RAM.. its a plain USB driver error.. crap :/
    Salamat sa mga tumulong ^_^
