Seasonic X650

[big dad]

Will this psu handle my set up? Seasonic x650 is on sale at NE and its full modular.

asus p8z77 - v pro
i5 3570k
2 gtx 670
1 ssd, 1 hdd,

+ water cooling (1 360 rad, swiftech mcp655)

 

[Tsumi]

Yes.

 

[Ali Man]

The X750 would be better for two 670's.

Seems like it would be pushing it, assuming you're gonna OC. I mean Seasonic units handle their rated power well, unlike some PSU's, but I personally like to give myself headroom.

 

[ParasiticJ]

You should be fine.

 

[Profumo]

Comfortably, that's a <500W system at full load.

 

[big dad]

ill probably go for 750. just have to wait for a good deal. Thanks

If you're willing to hold out for BF, you might get some good deals. I got my antec earth watts 750w for $40 two years ago. Though it's not the best PSU I'm sure you can get a nice unit sub $100.

Though it might be hard holding out that long if you have all those components ready to go

Right now I have a Antec HCG 520w. for now, will this hold 1 gtx670? So i can wait for BF to get a new psu?

 

[Tsumi]

The HCG 520 has 480 watts available on the 12v rail, and it's a Seasonic design.

Assuming everything is at stock:
Each GTX 670 is less than 200 watts under load.
The 3570k is less than 70 watts under load.
System peripherals are less than 50 watts.

Yes, you will be fine putting both 670s on the HCG 520.

And while you're holding out, just look for the Seasonic X750 to go on sale for ~$110. It does this about once every 2 months or so.

yeah I think Tsumi's math works out pretty good. Maybe monitor the rails during some heavy benching and run that machine stock until you can snatch up a good 750-850W PSU.
