PSU that can handle 3x R9 290's

[target39]

I'm not looking to go 3 way now, 2 way first then I'll see how I go.

That's a bit cheaper but it's only a silver. With 3 290's I want a platinum.

If you can wait until May, then sure, the Antec HCP-1300 is your best bet.

You got the dates around the wrong way mate haha It'll be in stock in about 3 days. 5th of Feb.

The Seasonic I posted is not that far off from 80 PLUS Platinum though. At 50% load it reaches 91.4% efficiency at 115V. Platinum is 92% at 115V (it's 94% at 240V, but the efficiency of the PSU increases with the voltage too).

See just how close it came to Platinum (less than or equal to 0.6% difference):

R9-290's OC'ed can consume up to 360W of power according to a fellow on the TS.  Before he returned his, his OC'ed 2600K @ 5.3GHz @ 1.48V and an R9-290 @ +50% power blew the breaker on his 650W PSU lol.

A good PSU over 850 should be able to handle it without overclocking. If you want to OC or like to run P95+furmark all day then get 1000+

Even the best 650W's won't be able to handle that kind of overclock. In his situation honestly the CPU overclock is pulling a lot more power then the 290 overclock.

Sorry to open up a new portion on this discussion more than a year later. I have the Xfx 1050 pro gold with triple XFX DD R9-290's, fx 8350 water cooled, 14 gb Gskill, Asus CFV, 1 SSd, 4 hdd, and 6 case fans. I run 4k on a 28 inch Samsung monitor. Is this PSU enough or will I burn up the PSU. It's only two weeks or so out of the box?
