Do i really need to upgrade my psu?

I wanted to buy a radeon hd 7770.My system specs are as follows:
fx 6300
78lmt usb3 mobo
4gb of ram
450 watt frontech psu(local psu not branded)
with +12v-19Amps
I want to play battlefield 3 at ultra
it is not important that bf4 runs on ultra(at high would be more than enough for me)

I actually wanted to ask that if it is possible that my stock psu can be used because I dont have enough money to buy a hd 7770 with a branded psu

  1. Yup. I'd call that a fire hazard

    A good 500W+ PSU from the second link in my sig should be invested in ASAP.
  2. i dont think ultra is going to happen with the 7770 unless your at like 720p

    get at least a r9 270 and a new 700w 80+ if you want to crossfire it
  3. Let me rephrase your question:
    -"will the 7770 be able to run bf4 on ultra?"
    -"will i need to upgrade my psu as it is a 450 watt local psu?"

    the answer to that is:
    You will not be able to play bf4 with 7770 on ultra.
    You will need atleast an r9 270 or r9 270x or a gtx 660ti.

    for the psu, you should get atleast a decent 80+ bronze certified 500 watt psu. ( I have been running a fx 6300+ r9 270 with cx430v2 for about 6 months without problem on stock, but i still suggest u buy a 500 watt psu)
    but if you want to stick with the 7770 then a 400watt psu should be enough.
  4. My 6850 which is a little faster than a 7770 (7790 is a little faster than 6850) could not max out BF4 on with my i7. I was close but had to turn down a few things but still got it to look good. When I got my gtx 670 of course I was able to max bf3 but it could not max bf4 which is why I got a 780ti. Excluding the 780ti I ran the first two cards on my 400w OEM PSU and both overclocked with no issues for years.

    Performance wise you should at least go 750 ($100) or 750ti ($150) both of which beat a 7790/260x. This site has helped me cherry pick GPU's over the years helping me get the most performance for my money:

    Just ignore the 2-in-1 GPUs on this site they are only measured on single card performance.
  5. Passmark is still pretty inaccurate, even ignoring the whole dual GPU issue.

    750Ti isn't a good pick for the money.
  6. GTX 750 is dead even with 260x/7790 and can be found for $100. The cheapest 7790 I have been able to find is for $125. 750ti for $150 is always faster than 260x/7790 OP wanted a 7770 which I was trying to talk them out of.

    You could be a little faster with a $150 r7 265 but also have higher power requirements.
  7. Tom's seems to think the 260X is about as fast as the 750Ti for more money: http://www.tomshardware.com/reviews/gaming-graphics-card-review,3107-3.html
  8. I checked out a few more benchmarks, all the cards are close with 750ti being on top most of the time by a small margin but also with a slightly higher cost. R7 265 seems the be the new value leader @ $150.

    that means my radeon hd 7770 will work perfectly on an oem psu....

    I was lucky and also didn't have the option to get a 750ti which is a lot more power efficient and still my recommendation with your PSU.
