550w power supply enough for i7-4790k, 980ti and 2x3.5 hard drives?

[bydus]

Like in the title will 550w power supply handle such config without skipping a beat?

[jurian123]

Should be yeah.

Depends on what psu it is.

A good quality one from let's say Seasonic, XFX, EVGA should work fine.

Easily.

[cragger89]

If your chip isn't over clocked, I would say it'd be OK

 

Personally, I would want a little more headroom, but my entry level Corsair which is a CX430 handles my i3 4160, SSD and HDD and R7870 GPU without any signs of struggling.

 

What is the make and model of your PSU?

Depends on the efficiency.

650w gold 80+ psu would be enough.

[Goldensapling]

Yes

[Shadow-R]

Terve!

You'll need to tell us what 550W PSU.

Cannot tell you more right now.

Also: If you have a crappy PSU, I would not take the risk of your PSU killing you nice new GPU.

Sayonara!

[MegaDave91]

I'd go with 620

Efficiency has nothing to do with the wattage.  A 550 crap power supply will still supply 550 watts, but may draw 650 watts from the wall, where a good one will also supply 550 watts, but will only draw 600 watts from the wall.

no it doesn't.

He better go with a quality 500 Watt PSU, then with a crappy 620(?)Watt one ...

[Speaker1264]

OC3D has a nice graph that shows the power consumption of their system with an overclocked 4960x (Uses ~50% more power than a 4790k), 4 sticks of ram (Uses ~100% more power than 2 sticks of ram), and an overclocked gtx 980ti drawing only about 457 watts.  Taking the power supplies efficiency into account this means the whole system only required about 410 watts to run.  I'm pretty sure 550 watts is more than enough.

[MegaDave91]

no it doesn't.

I made no mention of a "crappy" 620W...

[paprikman]

no it doesn't.

 

Ok, let him install 600w psu with 10% eff and ruin the system.

[Duskie]

This was already explained by Speaker..

you obviously have no idea about PSUs and therefore better avoid those threads in the future.

still a higher quality 500/550W psu is a better choice, than a lesser quality 620W one

Not sure if all crappy PSUs live up to their ratings

[MegaDave91]

And vice versa for the 620w...not sure what you're alluding to.

How will He have 10% efficiency ?
