Hi guys,i have a Corsair HX850 PSU,and i want to get 2 R9 290X cards in CF,but if i do i will not have money for any other upgrade,so my question is will it work?I have an Asrock Z77 Extreme 4 mobo,i7 3770K CPU clocked at 4.5 Ghz,8 Gb DDR 3 ram,1 TB HDD+64 Gb SSD for Windows,and a Coolermaster HAF 932 case.I WILL NOT planning to overclock these cards!I will use them both in uber mode,i maybe let the fans go up to 100% if it's too hot,but i will not overclock the cards at all.
An can that cause any harm to the PSU or the cards?(or anything else) If not than I'm okay with that,since im not planning to overclock as I said,or install any new hardware for a time.
Nah, but I wouldn't push too much voltage in that 3770K. Power consumption can spin out of control on these chips. What voltage are you running for 4.5GHz? I don't think you will be able to bear 100% fan on these so consider thermals. Might be best to wait for custom coolers or install two yourself (watch out for height restrictions and airflow)?
No, i mean the noise. Running the cooler at 100% will keep the clocks up and the temps down; this can slightly decrease power consumption.

CPU will be more than 100W if that voltage is high (don't know about Ivy Bridge voltages). Otherwise yeah your calculations are pretty accurate. True, HX850 can do 1000W. I have the same PSU.
Water brings temperatures down, what do you mean by power consumption down?They use more fans, fan controller panel, and a pump or 2.
Yeah I have 12 fans and one D5 pump, both my 670's run at 1.212V and my CPU is at 1.4V when it ramps up so I was a bit worried that I was pushing it on only 850W.
Can bring GPU power consumption down 30W or more in many cases. Bitcoin miners watercool for that. Less heat = less transistor leakage = less current drawn - less power drawn. IBM watercooled one supercomputer of theirs to bring down power consumption 10%. The pumps and fans use a fraction of the power they save, especially when running fans at less than 100% and a pump on low with low-restriction waterblocks and radiators.
Well i have the cards,I tested heaven bench,crysis 3,3D mark 11,hitman absolution,everything was fine until i started a metro last light test...screen froze,i restarted,and BSOD...Could be a driver error,or the PSU is not enough?Or something else?This PSU is 3 years old i bought it around the summer of 2010.
I hope so :/ after the bsod windows offered me a repair option and warned me that recently installed programs could be removed,it removed catalyst,i reinstalled and i did not see my second card in cf...i restarted again,now it sees it again.Some info on the BSOD:"The system has rebooted without first shutting down properly. This error could occur is because the system does not respond, or collapse unexpectedly terminated the power supply" Not sure if this is accurate,im from hungary,so the messsage was in hungarian,i just used google translator" - EventData BugcheckCode 0 BugcheckParameter1 0x0 BugcheckParameter2 0x0 BugcheckParameter3 0x0 BugcheckParameter4 0x0 SleepInProgress false PowerButtonTimestamp 0
