xfx 550w pro core edition 80 plus bronze is good enough for gtx 770?

my rig
gtx 550 ti upgrading for gtx 770/970
i5 3330
4gb ram
GA h61m-s1
aerocool strike x one
1tb hd toshiba
250gb hd western digital
dvd player
mouse and keyboard
my psu is the XFX pro 550w core edition 80PLUS bronze
one guy recommended this psu for me when i asked here which psu should i buy for the GTX 770 (http://www.tomshardware.com/answers/id-2173087/buy-ps4-gtx-770-psu.html)
but i'm a little afraid of using it with the gtx 770
because NVIDIA recommends at least 600w but i already buy the PSU
so what should i do? can someone help me?

  1. It will work fine, but personally, I'd rather have a 600W version of that PSU for a little more headroom. Nvidia has to aim a bit higher because they have no idea what kind of "600W" PSU folks will try to use.
  2. I have a 550W PSU for my GTX 780, no problems.
  3. The next model up is the 650w, you should be fine with the 500w but I would have coughed up the extra 35-40 for the 650 myself. If the part is still in the box unopened you should be able to return right or did you buy it back in June?

    i live in brasil and the price here of the 650 was 125RS more expensive compared with the 550w 295RS wich is very high price so it was out of what i could expend and i would have to buy the gtx 770 only in the end of the year instead of buying it in 10/15/2014
    and the version of the PNY gtx 770 that i'm going to use is the one with 3 coolers

    You'll be OK, then. The XFX is a good brand, well made. My XFX 850W BE has lasted through several builds. That 550W is probably the equivalent of many lower quality 600W - 650W PSUs.

    man i hope it didn't pfft (sound of a burning psu) when i install it ty and have a nice gameplay :P
  7. Yep the power consumption of a 770 is like 300W-400W including system max and the psu is good so it'll handle it with overclock too

    one more thing,sometimes my pc takes long to open windows explorer and other apps, is this caused by the 4gb of ram (it is called markvision)? it is the lowest price that i found, so i bought it , it is 1333mhz should i buy more 4 or buy one of 8 from corsair or other good brand? if it is not caused by the RAM, so what it should be?
    i already defrag the HD and i used the ccleaner

    then, the psu will handle and nothing wrong will happen?

    You may have too much stuff starting with Windows. Check your TRAY and see how many of those apps you can live w/o. Either uninstall them or at least disable them from starting with Win. Run them as necessary.
    You can open System Configuration/Startup and uncheck the boxes you don't need. I only have 5 boxes checked for comparison. How many do you have?

    Do you have a network Hard Drive connected to your router? A NAS? Sometimes Win will wait for a cantankerous network device to finally register.

    You should always buy memory in matched pairs or sets of 4. Dual channel memory is very fussy about matched RAM. Timings, voltage, speed, even manufacturer and lot number.

    all programs are disabled i open them manually when i need
  13. i'm sure you all know better than the manufacture on this but like this evga gtx 770 states -- 600 watt or greater power supply with a minimum of 42 amps on the +12 volt rail.

    but i'm sure the 50w wount hurt in the short run [???]

    dude i will wait a little more and get gtx 970 instead of the gtx 770 nvidia recommends at least 500W for this card and it is faster than gtx 770 :D

    what if i buy gtx 970 instead of buying gtx 770? gtx 770 consumes 230 and gtx 970 consume 145, is this a good change? but to get gtx 970 i will wait till 11/30/2014 should i wait more?
  16. GTX 970's are out now , just selling out fast , wait and get one.
