can i has 290?

[boggle4321]

i have a 550W power supply, and i plan to get an R9 290. but i dont know if i have enought power.

 

i have 3570k and 2X mechanical HDDs

might be a tad little, go and use a wattage calculator to find out if you can do it

Whats the efficiency

they dont have 290 as an option, so i guessed it would be similar to a 7970, and came to 530W

always add 20% over what any calculator tells you. so I would go to far as to say you can not has 290 on that PSU

[amintha1992]

it should be fine.

 

is your CPU overclocked? are you planing to OC the GPU?

[boggle4321]

it should be fine.

cpu is very lightly overclocked, gpu will not be overclocked 

[wtfxmitchell]

should be fine, i have a 7950 with a 500 watt psu

[legopc]

i think it will be just on the edge so do it  

[amintha1992]

cpu is very lightly overclocked, gpu will not be overclocked 

then it should be fine the CPU will pull about 100w at the max OC, and lets say GPU pulls just about 300w(that is what linus said that the 290x used) at the max that is still less than 550. its borderline but not bad.

 

you should be good but i recommend getting at least a 600w PSU as soon as you can.

 

hard disks and other things are negligible.

Max tdp of the r9-290 is 300w. Your cpy is around 100 oc'd. The rest of the system wilkbbe around 50. So 450w is your load which is perfect for a 550w. Especially b.c the xfx is a seasonic oem.

[EpicGeekonFire]

Ehh Bet thing when it comes to Power supplies is to not meet the reqs for the system wattage. Say your build uses 500 wats exactly and you have a 500 watt psu... its going to be working its butt off to keep the system up. If you get a 800 watt PSU you can give the Psu some room to breathe and also have space to had things in down the line.

Whats the efficiency

How does this matter here? Irrespective of efficiency, any decent 550W PSU will supply 550W of power to the system.

[VSG]

OP, what else you got in your system? Are you planning to watercool the CPU or GPU? Are you going to overclock/overvolt the GPU? If not, then that 550W PSU should be fine.

[flibberdipper]

If you are at all unsure, just knock it up 100 watts. Works for me.

In case it's some crappy PSU with horrible efficiency (the ones that come with $20 cases for example)

[VSG]

I think you may have confused PSU efficiency- bad efficiency only means the PSU will draw more from the socket to provide the 550W to the system. But yes, no one should cheap out on a PSU.

[lachyman]

It will be fine, feel free to get a new GPU.

[FernandoTeixeira]

I think some people are crazy about psu ... already run 2x 7970 with a CX600...

some people would say it's impossibru

 

 

and before people ask how, with molex adapter

[BatteryAziz]

An overclocked 3570k with all the other components combined take up 150 at max (ivys are efficient even overclocked). So I'd say you've got yourself about 350~400W headroom for the GPU alone. You should be fine, just don't go nuts with dice/ln2
