Is a empire 680w enough for this?

hi guys i recently upgraded my system so i want to know if an empire 680w psu is enough for this: core i7 920 @ 2.67Ghz Ati Radeon HD 5870 6GB DDR3 triple-channel ram asus p6t motherboard and a 1.5TB seagate HDD so what do you think?

More about empire 680w this
  1. Recommended wattage from the Newegg PSU calculator is 577 watts for your build.
  2. I wouldn't always put stock in a calculator for final needs. I have always been told to leave a ltle more then enough room. 150-200 watts or so. I cld be wrong but always better to be safe then sry.
  3. thanks guys if newegg is right i have 103 watts more than i need... good!
  4. ^ More than the wattage of the PSU, the Quality and the amount of amperage on the 12V rails are more important...
    For the components that you have listed, even a 500W PSU from Antec EA/ Corsair/ Silverstone/ Seasonic/ PCP&S can power it without any issues...
    And your "empire 680w" is not heard of...could you give more details about that PSU...
    If you ask me, for the amount that you are spending on the other components, spend more and get a Tier I company PSU(Companies that I have listed)...
  5. well there was no very good psu at the store.. well i will wite here whats on the box:max output: 680w
    input:110/220v 10/6a 50/60hz
    output:+3.3v +5v +12v1 12v2 -12v 5vsb
    amperage:32a 30a 20a 20a 0.8a 2.0a
    maybe it helps and i know that empire makes coolers too, anyway, they are not that famous too... i live in brazil and here these things are very expensive i payed 850 reais on the p6t motherboard, 920reais on the i7,660 reais on ram and 390 reais on the psu and 450 reais on the HDD, each dollar is 1.8 real(in the plural, reais) the only thing i haven't bought yet is the gpu
  6. guys i searched on the internet and i discovered that empire is brazilian (it can mea that it's really, really bad) and here is the website it's in portuguese, please i wanna know if the font would suport my system or if it is real crap.
  7. Well, gurus, I looked at and translated the advertised specs as well as I could. Here they are:
    +3.3V-30A +5V-28A +12V1-16A +12V2-16A -12V-0.8A +5Vsb(stand by)-2A
    1x 20+4 pin 1x 4 pin 3x molex 6x sata 1x fdd 2x 6+2 pciE
    Looks like 1x 120mm fan
    With the 10A at 110V input that would give a maximum input of 1100 watts in, which (at 680 watts out) would give it a theoretical efficiency of 62%. I have no clue if that reflects the actual efficiency, but that is what those wattages come out to. I would think it is fine; do you?

    EDIT: IGNORE THE EFFICIENCY NUMBER! It is worthless, see below.
  8. well elel's information is almost the same in the box the only difference is that the 12v1 and 12v2 have 20a well i don't think thats relevant btw
  9. lol 62% you would end up buying that PC twice over by the time the PSU dies in how much you need to pay for the extra electricity to power it lol.
  10. well... there is no clue that this is the real efficiency... if it is i'll have to buy a new one..omg

    Sorry to worry everyone with my efficiency calculation. If the PSU was taking in that much power and putting 650W out, that would be the efficiency. But for comparison I took a thermatek 750 watt 80+ bronze certified supply (whatever was at the top of newegg), calculated the efficiency using analogous numbers, and came up with about 65%. I'm guessing that the rated amperage is like maximum possible ever and more for figuring out breakerage of the circuit that it's on than actual consumption numbers. So - ignore the number.
  12. well thank ya... anyway i don't really know the efficiency of my psu, there is no info on the box... i could buy another psu but i don't have much money avaiable right now
  13. @elel that is not the right method of calculating the efficiency...
    For eg., take that Thermaltake is rated at 750W with 80+ Bronze -> ~85% efficiency...
    So it actually pulls about 750*100/85 = ~883W from the wall...
    So if that Empire PSU say has about 70% efficiency -> It would pull ~972W...
    If the efficiency is much lower, then it would pull even more...
    But again this also depends on the PFC...If that PSU has Active PFC, then only the above calculation applies...Else it would pull the full power that the wall socket provides -> 1100-1200W to give that 680W...
    So it is always better to get a PSU with Active PFC and efficient PSU to keep in check the power usage...
  14. Yes, I found that out. Thanks. I put a disclaimer in the first message, but I guess I should have known that people would see the number instead of the disclaimer. I'll edit the message so no one is confused. I guess this was a case of being too smart for my own good :)
  15. but i don't know if my psu will really "deliver" me 680w... how can i calculate it?
  16. There is no way to calculate that unless you know enough to design your own. You would need to know the wattage of the parts, the schematic, the heat transfer, etc. You generally look for the reputation of the manufacturer, except in this case no one knows about them. No mater how I search I don't seem to find any reference to them, but that is probably because I live in the US. Again, I would feel good myself, and what do intel builders think?
  17. well even in brazil there aren't that many references, probably because this is a relatively new brand on the market but i saw test that a 420w empire psu delivered 280w.. and it's very strange that on the box ther is no info about the efficiency
  18. ^ Assuming that the Empire PSUs deliver power in that ratio, the 680W PSU would actually give out ~450W of power and that too not guranteed - Which is very much low for a HD 5870 and i7 setup...
  19. well it looks like i'll have to use my old 7900 for a while.... but will this psu handle my pc with the 7900 properly?
  20. ^ That should not be a problem...
  21. thanx guys... i'll use 7900 until i buy my new psu.. thanks!!
