Wattagez

[Paralectic]

Would a Corsair RM 550w 80+ Gold PSU be a good enough power supply ( in terms of wattage ) for this build:

Core i5 4690K overclocked to 5Ghz with a H100i on a Z97 mobo.

Geforce GTX 780Ti overclocked to it's maximum potentional or a GTX 880/R9 290X.

1 SSD, 2 HDDs with a few peripherals ( Headphones, speakers, joystick, xbox controller, keyboard, mouse ).

 

Would it ever need more power than the PSU can deliver?

Just curious on your opinion, I have done several wattage calculator tests but they vary alot.

I it should be ok, 780ti TDP is 250 watt under full load

and its 130 for the i5

 

Its cutting it close I would say get 650 watt to be safe

I don't see a single GPU of the Maxwell series draw more than 300, say 150 for the i5 there's 100 left for the drives and peripherals so I indeed doubt it will ever lack.

 

650 over 550 isn't required ever and would be a waste of money I suppose.

yeah as I say it should be ok I only got an 850 because I plan on a second 780ti so 550 should be okay

 

Its very rare you would be anywhere close to 100% usage

Should be fine but why are you asking this lol? You should know this with all your experience and advice.

It's enough.

It give one some reassurance to hear a forum of other people agree with you. I get it.

Btw, if you're going to be pushing your components as far as they'll go, I'd recommend a higher quality Power Supply. I know the RM850 series is 'good enough' and maybe I'm being a PSU snob, but I wouldn't want those crappy capacitors in a build where to power supply will be pushing close to its full load once overclocked.

Go for a Seasonic rebrand

The Cooler Master V650 fully modular Power supply is a Seasonic KM3 rebrand (meaning all Japanese capacitors) , and comes with a similar warranty period.
