Nvidia GTX 960, 970 or AMD new R9 380 or 390 and remember you probably need to change out the powersupply.


be carefull of seller arguments.
The gtx 960 is given for approximatively 120W, any modern cpu with NO low power cosumption is about 70-90W .
a hard drive is a joke -> about 10W..
let's be crazy and say the whole motherbord consume 50W
we have total of approximatively 250-260W ..

with a supra shit 400W 60% power supply, indeed it's dangerous.. with a 80% which is a standard now, it's enough.
so think to change your power supply if you're not sure or under 400W.


All is on 12V so you need at least 15Amp for 960 20amp 970 and 380 30amp for 390 so a 400W powersupply is to litle in the lowend they have maybe 15amp on 12V then they start to burn, better to go for overdimantion powersupply then start a fire.

And ofc with age it start to deliver less.

all depends on manufacturer.
Indeed, starting a fire or just blowing your PSU to gain 20$ is not a good idea.
In the contratry, buying an over rated PSU is a completely loss, since the effiency decrease on low power load

some system specs sources:

Code:
Power consumption Radeon R9-390X

    System in IDLE = 94W
    System Wattage with GPU in FULL Stress = 342W
    Difference (GPU load) = 248W
    Add average IDLE wattage ~10W
    Subjective obtained GPU power consumption = ~ 258 Watts

the chart on guru3D show big difference between GPUs. (beware GTX980 and GTX980TI are not the same GPUs : GTX 980 = 171 W, GTX 980 TI = 250W)
this chart is calculated, and seems to be on the wire, so real power consumption factured (with the loss of the PSU).

I'm sorry but I stick to my first idea that power consumption is often (not always) over rated. There is no need to have a 800W or 950W PSU because you have 4 HDD, 8Fans and a kick-ass GPU..
For me, having a 100W margin power is what you need when you buy a new PSU, more is wasting money and power. Less is indeed, a little risky.

PSU's are maximally efficient at half load. The correct goal is to get a unit which is at half load when you're using the most power, because that's when efficiency matters the most. So if, in a game, you're using 400W, you want a PSU of about 800W capacity. And that's a quality PSU, not a POS that supplies half its power at 3.3V and 5V. It should also have only one 12V rail, so you don't run into balancing issues.

PSU max efficiency starts at 50 % load, and keep it approximatively until 80-85% load...
if you use your PC like a game console, it could be a good idea to calculate everything to be around 70% load... ok, if you want.
but even your 50% load calculation is bad idea ! everytime you don't play game using max resources, you're loosing more power than what you gain at max efficiency. PSU are a lot less efficient on low power thant on high power consumption.
And I know no one powering his computer only to play games (of course it's only a personnal feeling).
Even me, at my WoW time, my computer could have been at 30% load average. because, there is no 100% playing on machine uptime. count the time your computer just idle because you're to lazy to switch it off (or you'll be back in 30min), time surfing web, time watching porn, time on facebook, eating, time powered on all night because you're downloading something ....

finished here, my last post.

Something like Corsairs CX 750 for high end and CX600 for GTX 970 then you have so you should not have any problem even after 2years and not that expensive.
