GTX 770 4GB: 600 Watt Power Supply?

Matthew-san · Mar 5, 2014

I was wondering if a 600 watt power supply was enough to power a GTX 770 4GB gpu? It also has to be able to power a FX-8320 processor, 1TB Hard Drive, 970A Motherboard, and 8GB of RAM. If not, then what would be sufficient?

Exact power supply?

Although technically it is enough if it truly provides that wattage.

600w is the listed requirements so you will be fine, some people can probably get away with 550w or 500.

A 600w PSU should be enough to cover everything. I did a quick check using the OuterVision PSU calculator website, and your rig will draw around 500W to 533W.
If you decide to add more hard drives, fan or a waterloop, you might find yourself exceeding the 600w limit, but your current build should be OK.

In addition to what ak47 (please actually do some research before posting!) a 500w would NOT cover your system, and a 550w would be limiting your options.
As always go with a NAME BRAND PSU. There are a ton of those cheapo 1000W power supply units out there that will simply blow up if you draw anything over 600w from them. Corsair, SeaSonic and OCZ are forum favorites. If you need help finding a decent PSU you need only ask.

Don't take my word for it:http://www.guru3d.com/articles_pages/msi_geforce_gtx_770_gaming_review,5.html

Dear,

600W is plenty for your system. Make sure that it has 40+ Amps on its +12v rail(s).

Matthew-san · Mar 5, 2014

Thanks for all the answers, I have a Thermaltake PSU and I'm not sure about the 40+ Amps but I'll make sure it does before I install anything new. In the near future I plan on adding another hard drive, upgrading to 16GB of RAM, and possibly running two GTX 770's in SLI config. What do you guys suggest I would need for that set-up? (I don't plan on overclocking)

Matthew-san :

With two 770s you've to pick 750W PSU.

Matthew-san · Mar 5, 2014

Alright, in the future I'll probably get one of the modular 750 Watt PSU's from Corsair.
