Hello there, i have a question regarding PSU. My current PSU is 700w. my current pc build is dual xeon x5650, 16gb of ddr3 1333mhz server ram, gtx 960 4gb. i have a Dvd-rom drive for burning discs, i have a speaker. As a whole my machine is a fujitsu celsius r570-2 workstation as you can see. I plan to upgrade to a gtx 1070ti and dual xeon x5690's and 32gb of ddr3 13333mhz server ram. So my question is will this 700w power supply be enough. Do i need to uprgade that as well. Also i have 2-3 big fans inside dont know the measurements anad 1 small. Also if its not enough give me some examples if u will for a psu that will suit best this build ( brand, watts, etc.)
 
Workstation PSUs tend to be rated at continuos power and not peak advertised power so they're usually better than they would seem.
You 2- CPUs 130W+130W and GTx1070 150W= 410W so you should be OK.
I would like to point out that LGA1366 Xeon CPUs support 3 channel DDR3 1333 RAM. This means set of three modules, not 3 pairs.
Good RAM configurations will be divisible by 3, such as 24GB,36GB 48GB. They CAN run 2 channel, and even some strange Flex Mode setups but all with significant loss in performance.

Thank alot for the answers. So it should be all good. The smaller parts of the pc such as the fans dvd rom etc dont draw that much power? Also i know this is a bit out of topic but you mentioned 36GB of ram? Didn't get that part well. I currently have 4 pairs ot 4gb of ram installed on the sockets(1333mhz).My wish is to upgrade to 32GB in other words its not gonna be 32 but 36GB? Also can you recommend me some ram setup, should i run 4x8gb or shuld i run 2x16gb if i find any?
 
You should run 3, or 6 modules in sets of 3. For example 3x8GB +3x4GB=36GB. This is what allows these old workstations to still be relevant.
Does your MB have 6 RAM socket for each CPU? ALL LGA 1366 CPUs have the memory controller on the CPU. They all support 3 channel RAM which has 50% more bandwidth than 2 channel DDR3.
The manual for that shows 3 RAM slots for each CPU.

3x4GB for each CPU would be (6x4GB) 24GB. The next step up would be 3x8GB for each CPU (6x8GB) 48GB. DDR3 1333 RDIMM ECC

Ah now i understand! Thanks alot! And last question with that amount of ram the 700w psu would still be enought right? And yeah the Ram sockets are 6. The motherboard can have up to 96 or 98 gb of ram forgot witch number was it.
