I currently have a R9 295x2 with a 1000w PSU and intel i7-4790k I was wondering if anyone knows if I could put a R9 290x in and do trifire, but I'm not sure if I have a big enough PSU
\
Again, he has a very high-end PSU that can deliver 1000W to his computer 24/7 if it's ever required. What, do you think that pulling 1001W would hurt his PSU? This thing isn't a toy, you know. It's also not peak-rated, it's CONTINUOUS-rated.
And I think that he would be wise to test it and to also use a wall meter to see what his power consumption is while gaming. Why should he spend that much money on a new PSU in addition to the R9 290X before finding out if he even needs to?! A wall meter is only about $20!
You have a continuous-rated PSU.
Dude, I'm still waiting for him to answer my questions that I posted in Post #2! Let's relax a little bit while we wait? Y'know? Let's not jump to conclusions?
Do you realize that 1000W at the wall with 90% PSU efficiency is 900W? For his PSU, delivering 900W out of the 1000W continuous capacity that it has is pretty easy.
He will be so close to maximum or over that it will be a problem in the long run. The power draw is going to fluctuate and if hes pulling around 1kw it may spike up and or increase with temps. He didn't mentioned if he intends to overclock them as he won't be able to. He could just overclock his 295x2 to get better performance while it wont match trifire in a game that supports good scaling. I honestly couldn't recommend him doing trifire on 1kw psu myself, as many others here have posted who do have the hardware.Originally Posted by TwoCables
Sigh...You guys aren't listening. I'm sorry, but you're not!

Dude, he has only made one post, and that's the original post! I'm still waiting for him to reply to my first post in this thread. So, I'm not going to jump to any conclusions until I can do a Q&A with him. So, his reason for not mentioning overclocking yet is he hasn't been back to OCN yet.Originally Posted by DividebyZERO

Do you plan to overclock the CPU? Ever?
Why?
Why not?
Because, AMD GPUs like the 290(290x/295x2 use XDMA engine, which uses PCIe bandwidth,therefore 2x gpus would be using 8x bandwidth, i havent seen any test with 16 lanes, just people running PLX
lol, it's not a lane doubler. It's not magic ppl. The PLX is a multiplexer, it's like a crossing guard directing traffic. All that traffic still has to go thru the original x16 lanes on the cpu die.
Sigh. Would you drop that attitude already? Good lord, dude. I am waiting for him to tell me if he will ever overclock his CPU. Did you see that? He doesn't have his CPU overclocked right now, so the logical response is to ask if he will ever overclock it. Did you also see that he will NOT overclock his 295x2 anymore once he puts the 290X in?
