The PSU Thread: New Products and Reviews

  • Mga sir itatanong ko lang sana kung pwede ko enable yong c6/c7 sleep state sa procie ko. I5-4690K, my PSU is Seasonic M12 II 520w Evo po. Thanx
  • ^ Sa Bios saka bago ka mag enable nyan make sure na supported ng PSU ang C6/C7 state
  • hi ask ko lang po sa mga marurunong kung advisable ang 90w pico psu sa a10 7800 na build? ang ilalagay ko lang pong kasama niya ay 16 gb na ddr3 memory at 1 ssd sata 3.0 thanks
  • ^ Pwede yan since FM2+ APU ay may CTDP (Configurable TDP) pwede iset yan sa 65W o 45W para hindi masira agad yung PSU
  • ^

    salamat po boss
  • guys suggestions naman ng good psu, bumigay na kasi kagabi yung corsair hx620watts ko halos 7 years ko na siya nagamit

    eto sana ipapalit ko ok ba eto corsair parin naman (Corsair VS550, Corsair CX600, Corsair VS650) nag re range ang price niya sa 2,000to 3,000

    specs ng pc ko lang naman ay

    core i3 3.30ghz
    asrock h61m-dgs motherboard,
    evga gtx 750 video card
    4gb corsair vengeance
    1tb western blue
    1 optical drives
    3fans
    later on mag upgrade ako sa liquid cooling kapag may budget na,


    ok ba yang choices ko na psu, hanggang ganyan lang budget ko kasi wala naman ako balak mag overclock or mag sli, ayoko na bimili na masyado mahal ngayon.. any suggestions???
  • Seasonic na lang sir, eco 400bt or 500bt or s12ii pasok naman lahat yan sa budget mo.
  • ^oks naba yan sir kahit 400 watts lang or 500watts, e kapag nag upgrade din ako sa core i5 kayanin paba balak ko din kasi
  • Kaya nyan kahit i5 na sandy, yung s12ii 520w at mataas efficiency kung talagang gusto mo makasigurado.

    Pero kahit yung eco 500BT kaya naman yan, sinubukan ko sa calculator yung specs mo palitan ng i5 ivy, lagyan ng water cooling kit, 1 HD, 1 SSD, 1 dvd, 4 usb devices, 2 120mm led fan, 2 80mm led fan, maximum load, maximum capacitor aging, 410 lang total.
  • ^
    salamat sa suggestion sir mas ok ba seasonic sa corsair? kung ok siya i'll go sa seasonic s12ii 620 watts nasa 3,300 siya
  • Short answer oo. Eto medyo informative at kakaupdate lang na ranking ng mga PSU: <click here for link>
  • @ warpspeeds

    bro wala pang 300w konsumo ng rig mo, at most 250w siguro yan after mo palitan ng i5 in the future. Get Seasonic 400BT na lang unless magpalit ka ng mas malakas na video card sa future.

    Di sulit binabayad mo sa 620w, max na siguro yung mga 520w ng seasonic just in case magpalit ka nga talaga ng video card sa future.


    EDIT: out of stock na yang mga S12II kung di ako nagkakamali. ang iniistock na lang nila M12II EVO. 1k din difference ng 520w at 620w EVO, at mas malaki pa matitipid mo kung mag ECO 400BT ka na lang.

    Sir yung Corsair HX620W mo is based on an older design of Seasonic S12II 620W model, so kung papalitan mo siya go with Seasonic ulit :-)

    Try mo maghanap ng Seasonic S12II 520W or 620W model pero kung wala ng stock like na mention ni Dyaems, go for Seasonic M12II 520W EVO. Yung Seasonic ECO BT series maganda din sir at very affordable pero hindi ako sure kung may same 5 year distro warranty sila. Yung S12II and M12II models have a 5 year warranty :-)
  • repost ko lang, nakita ko kasi may nagbebenta nito locally at sabi niya seasonic made daw. So chineck ko ang manufacturer at affiliated nga siya sa seasonic. Totoo din yung 80+ certification niya. First glance looks more like a Seasonic S12II psu. Ano sa tingin niyo>

  • ^ Seam good unit but warranty nalang ang problema sa ganyan unit
  • Di sulit binabayad mo sa 620w, max na siguro yung mga 520w ng seasonic just in case magpalit ka nga talaga ng video card sa future


    mukang napaisip ako dito ah, sa bagay kung hindi ko naman magagamit yung buong 620 watts sayang nga lng talaga ibabayad ko doon, kahit siguro mag upgrade ako ng mas malakas na video card in the future, at mag i5 tapos mag water cooling pako sapat na siguro yung 520watts..

    nasanay kasi ako sa dati kong psu na 620 watts, parang kakatakot kasi kapag konting watts nalang natira sa psu ko kapag nagkabit ako ng ngkabit baka mag KABOOM hehe..

    atlis meron nako peace of mind ngayon, try ko yang seasonic, sa pchub madami pa, siguro ill go sa m12II 520watts modular narin yata yun eh..

    by the way salamat sa sumagot nakatulong talaga sa akin, pati sa bulsa ko..
  • ^ hindi sayang ang 620w. tandaan mo may wear ang tear ang psu. bumababa ang output nito overtime kaya hindi porke mataas wattage mo eh para sa mas malaking headroom lang. para din to sa pagtagal ng psu mo.
  • Check nyo yung test system ng Hard OCP sa review ng GTX 980 <click here for link>

    Core i7 3770K @ 4.8 GHz + GTX 980 ay nasa 312 watts lang during gaming

    Take note na bababa pa ang power draw kung stock speed lang yung CPU at mas bababa pa kung Haswell CPU


    Ang mga high quality brands tulad ng Seasonic, may safety allowance ang rated power. For example, a 520-watt PSU
    can actually deliver more than 520 watts. Based on various PSU reviews I have read at Hardware Secrets, the safety allowance ranges from 50 to 100 watts

    Take note mo din ang effect ng wear sa PSU not only in wattage but also in ripple, noise, efficiency, heat output etc...

    HardOCP - SilverStone Olympia 1000W Power Supply 7 Year Redux
    <click here for link>

    After 7 years yung Silverstone Olympia nag out of spec na ang ripple / noise specification when loaded at 75% capacity, 100% capacity, and 80% capacity under hot conditions (torture test). So hindi na siya papasa sa HardOCP review and would not get the same rating as before. Note that the Silverstone Olympia is a server grade PSU and during the course of 7 years hindi naman siya used at near 100% capacity. Imagine mo nalang if you were using a consumer grade Seasonic PSU on an overclocked system for 5 years and more at 80% load. I'm sure baka hindi magiging stable ang overclock over time and you would have to lower speeds.

    Maganda din yung may konting allowance sa wattage ng PSU even if it's only by 100 watts para hindi aabot ng more than 50% - 60% load during long term usage. Ang difference in price on a Seasonic 520W PSU and 620W PSU is only Php 690, maliit na cost lang yun for the extra allowance of safety. I don't think you can spend that Php 690 any better to help extend the lifespan of a computer component.

    Also hindi rin natin alam if next generation videocards will have higher power requirements 3-5 years down the line. If you remember nung lumabas ang mga R9 280X and R9 290 videocards meron ilan napilitan mag upgrade ng PSU from a 500W model to a 600W model dahil nag-increase ang PSU requirements ng videocard. If they bought a 600W PSU from the start I'm sure malaki din natipid nila.

    Anyway there's nothing wrong in buying a 500W PSU and saving money. But there's also nothing wrong in spending a few hundred pesos more and getting a 600W PSU if you plan to use the PSU over 2-3 PC upgrades :-)

    Hard OCP made it clear that their test cannot be used to make a definitive answer or conclusion

    "We also want to remind readers that this entire conclusion is editorial in nature and that the results we present here are NOT meant to be a definitive answer or a scientifically rigorous answer for how use and age affect a power supply"

    They just tested one unit and the usage of the PSU during the 7.5-year period was not specified


    Imagine mo nalang if you were using a consumer grade Seasonic PSU on an overclocked system for 5 years and more at 80% load. I'm sure baka hindi magiging stable ang overclock over time and you would have to lower speeds.


    If we are talking about a modern high-end gaming PC with one GPU (Intel Haswell + NVIDIA Maxwell), it's hard to reach 80% loading on a 500-watt PSU

    And that "80% load" is not actually an 80% load since high-quality PSU's are under-rated


    Ang difference in price on a Seasonic 520W PSU and 620W PSU is only Php 690, maliit na cost lang yun for the extra allowance of safety. I don't think you can spend that Php 690 any better to help extend the lifespan of a computer component.


    Good point here but when the budget is really tight, that Php 690 difference can be used to get better components like CPU cooler, motherboard and casing

    I think this is about how each person sees the benefits and risks of their decisions and their speculations on the trend of energy efficiency of GPU's and CPU's

    Here's an example for GPU's
    5 generations of GeForce compared - power draw <click here for link>
    5 generations of Radeon compared - power draw <click here for link>

    If you'll ask me, I'll use the trend of NVIDIA GPU's in my purchase decision for a new PSU if I were to build a new PC. Performance is increasing while the power draw decreases

    Some may base on the trend of AMD GPU's in their purchase decision for a new PSU


    Which is right ? Nobody knows, only time will tell

    Well for me I have always preferred to go with a higher wattage PSU for long term usage, 5 years or more. If you have the extra budget there is nothing wrong with spending it on the extra PSU wattage unless budget is so tight that it will mean getting a slower processor or slower videocard or a case with less fans, or no CPU cooler etc.

    PSU wattage is fixed, so whatever PSU you get now you are stuck with that wattage limitation for 5 years or more unless you replace the PSU. Other components like harddrives, CPU coolers, case fans, memory (and even videocards) can be added on to your PC to increase capacity or performance. But with a PSU if you need more wattage you can't just add another PSU. You have to replace it with a higher capacity model and that will be more painful to the wallet.

    If also sticking with a lower wattage PSU will restrict you in the choice of videocards or hardware components you can use then that's not good. You want to be always flexible with hardware component choice especially if it means switching between Nvidia or AMD videocards in that 5-year span. Saving a few pesos on the PSU now can hit you hard in the future if you want to upgrade to that next generation AMD videocard that pulls more than 40A on the 12V rail. This has happened before.

    Ultimately its up to the buyer where he / she wants to prioritize spending the budget. But spending a bit more to get extra allowance on PSU wattage is a good decision for long term use.
  • ^ As I have said, only time will tell :)

    My basis in choosing a PSU is based on current trends of the energy efficiency of CPU's and GPU's. And based on the current trends, CPU's and GPU's are getting faster while requiring less power.
  • Ngayon ko lang naalala na i-measure yung 12v ng PSU ko kasi sa software ang laki ng tinatalon eh, from 12.250v nagiging (up to ) 11.6v pag umandar na yung video card.

    Sa chipipay (Newstar) na DMM na gamit ko nasa 12.16v ang reading nya, minsan nag drop to 12.15v pag medyo madami na nangyayari (sa games).

    EDIT: using molex method while playing/stressing/benching sa page 678

    EDIT2: apparently useless daw mag measure ng 12v @ load using DMM through molex. QQ na lang ako haha
