Best PSU for this build

Hello experts. This is my second post here.
I just bought a new PC for my assistant with a config. of:
ASUS P8-H61-MLX
Pentium Duel Core G620- 2.6 GHz
4 GB DDR3 1333MHz Memory
MSI GT 610 (1 GB DDR3) Graphics
500 GB x 2(TWO) Samsung SATA 3GB/s HDD
ASUS DVD RW

Now my query is what power supply will be best for this build. I am planning to buy Gigabyte PoweRock 300W. Will this be enough??? Or I need 300W+ PSU? Please let me know your thoughts..


Thanks in advance.

    Plenty, doesn't leave much in the way of upgrade room though

    Not much. You'd better take 500/550W PSU. I highly recommend getting this or this (much better option, but only if you can afford it).
    And I suggest that you stay away from Gigabyte's PSUs, they make total crap in that segment.

    Why ?

    56 watts running Prime
    http://www.legitreviews.com/article/1665/15/

    68 watts running Prime
    http://www.xbitlabs.com/articles/cpu/display/pentium-g850-g840-g620_7.html

    78 watts running Prime
    http://www.bit-tech.net/hardware/cpus/2011/10/31/the-best-100-processor/17

    Add a 29 watt GT610 to that, where's the need for 500/550 watts ?

    Some people around here recommend secondary PSU to power a handful of fans so I stopped asking.

    Many geeks just like recommending ridiculously oversized PSU by default even though a fully-loaded single-GPU single-CPU system rarely exceeds 300W, just need a real PSU rated for actual sustainable continuous power.

    You said it yourself, previously: so that he won't have to change the PSU when the time comes for him to make upgrades, in the future.
    I've recommended the "buy once & use without any problems for 5+ years while sustaining ability of future quality upgrades" PSU to him, while 300W~400W would become pretty much useless even after he makes just a little upgrade to the current build (not even to mention the entire or almost-entire upgrade).

    OP, you (of course) can do whatever you want, it's for you to decide in the end, but remember this:
    Most of the people that recommend such things, just simply cannot afford a really good High Tier/Top Tier model, or don't think about their PC's future at all.
    If that's your case, then, of course, you can get 300~400W PSU, no problem.
    But if you have money to spend, you should really take what I've suggested, you won't be disappointed even one bit.
    PSU is one of those cases (along with CPU Coolers and Motherboards) where buying something just because it's cheaper, would be a major mistake.

    With the 400 watt psu reccomended by Finneous, he could add a HD and some fans and any video card that requires a single 6 pin connector and not have any power worries
    With a good quality 450w unit he could add a $400 GTX670 and an I7, really don't see that happening considering the $340 ( no case/ psu ) H61 system he's starting off with
    Extreme overkill in the name of " future proofing " is even more silly when starting off with a low budget system

    It would make (some) sense if the PSU was intended for future transplantation in a higher-end system or rebuild.

    For the system as-is presuming the OP has the system he has because this is either all he can afford in the foreseeable future or all he needs, I agree, completely overkill.

    "Just bought a new PC for my assistant" sounds like it falls in the "all that is needed and unlikely to ever get a major upgrade" category: computer used for lightweight business use.

    Agreed

    Exactly my thoughts when I see specs like the OP gave

    Just for kicks I put my GTS450 in a somewhat similar system ( no quips about the dust, it mostly sits on a shelf ;) )



    P8H61 M
    I5-2310
    2x4Gb
    250Gb WD RE4
    Asus DVD/RW
    SS300-ET
    265w from the wall running Prime and Furmark
    172w running the Heaven demo

    Extreme OVERKILL


    I friggin' LOL'd. Totally ROFL'd. Since when 500W is an "Extreme OVERKILL!!!!!!!!!!!!1111"? LOL, I guess Corsair's 1200i would be a SuperNova to you...

    Anytime it's reccomended for a system that's only going to draw 100w, but then that's the issue with most people, no idea about system power consumption
  11. Hey friends please stop this debate among ourselves.
    Everyone of you have some point of what you have said. So all of you are right to some extent.
    Let me tell you one thing(I missed this in my original post)....
    I HAVE NO PLAN OF UPGRADING THIS PC IN THE FUTURE.

    Thanks...
  12. Get the 400 watter then.

    To be fair though, the way PCs and PC components are marketed, branded and sold, only the most aware of consumers have any idea of how much power their PC will end up using and how much of a difference a good/poor PSU can make. More is usually better than not enough, which makes it much easier to over-inflate recommendations than custom-fit them.

    Again I agree with what you're saying, but if someone is in the power supply section of the forum making reccomendations they should have a clue

    this seems even more brilliant =o 80 PLUS GOLD and the same amps on the 12V rail. On top of that Seasonic is arguably the best name when it comes to PSU's.
