cooler master 520w real power pro m520

[Jingibi]

my system specs are:
cpu i5 4690k + deep cool captain 120 liquid cooler
mb asus maximus VI formula
ram 2x4gb corsair 2400mhz
1x ssd
gpu ati 7850 2gb
psu cooler master 520w real power pro m520
3 120mm fans.....

my question is: is this PSU enough for crosfire with another 7850?
my cpu is not OC, everything on stock...

If you have enough PCIe power adapters, it's enough power, dual 7850 cards would use about 200 watts of power under gaming. But... that power supply is not very good quality, so the risk is there for crashing with dual cards. If you want to try it and see if it runs stable or if it simply crashes without any damage to the parts, up you to. If it was my system, I'd really think twice about adding a second card without changing for a better power supply.

It should be. I calculated it on http://outervision.com/power-supply-calculator and it said youll be using about 430.

i dont have second 7850, but i can i take it very cheap, so its better to change the PSU ? and idk is another 7850 will help increasing the fps?

If you only have 1 7850 then youll for sure be okay, you should even be okay with 2 7850. But youll see some increase. What games do you play?

You may want to sell your 7850 and replace it with a nVidia GTX 950 or 960, less power use, should be about as fast as dual 7850s, and with the money you get for the 7850 and save by not getting the second one, it should be the same cost.

gtx 960 is 128bit, is it better than the 7850?

 

[Jingibi]

also checked the PSU calculator, if thats true i can run 2 7850s, and idk but i think they should run better than that gtx960, imo
and i cant afford new card now or new psu, i can get that 2nd 7850 (old card) very cheap and if this will improve the performance of the games and "if" that psu is enough ... why not geting this card then?
first askin coz i dont wanna fvck up my pc
thanks btw guys for the quick response and sorry for my bad emglish

A second card will improve game speed for sure, but like I said, the power supply is not the best to run dual video cards. I'd wait for a bit till you can just sell your existing card and get a single better one that will use the same power.

While the memory bandwidth on the 7850 is better than the 960, the 960 is still a much faster video card.

So, i decided to buy new card.
ASUS GeForce GTX 960 DirectCU II OC 2GB GDDR5 128bit 220euros
or i can take for 30 plus euros this one
MSI Radeon R9 380 4GB GDDR5 256bit 250 euros
the ati is 4gb and 256bit, im no expert but for 30 more E this card seems better imo

For overall speed at something like 1080 resolutions, the 960 and R9 380 are about the same. For some games, the extra RAM and memory bandwidth would make a difference though, and if you play on higher than 1080 then the R9 380 is better in many cases, although by not a huge margin.

Take a look at this http://www.eurogamer.net/articles/digitalfoundry-2015-nvidia-geforce-gtx-960-2gb-vs-4gb-review it's exactly what you need to check out. I'd get a GTX 960 4 GB version and overclock it a bit, or get an OC version of the 960. Less power, same speed as the 380 and should be cheaper for you.
