Recently CORSAIR psu got crashed and unable to supply full power to machine and machine keep rebooting intermittently, i checked with technician and he told that psu need to be replaced, CORSAIR psu is out of warranty
Now I have to buy new psu unit

I already have coolermaster mve 450 standard (white 80+) ready in hand
Will above suffice
OR
I should get 550w psu from cooler master or some other brand

Psu calculator showing i need 350w ( recommended)
Computer is used as hypervisor to run multiple virtual machines

Any pointers would be appreciated

Thanks

So 400w psu will do according to you, correct?
Is there any guide line that computer utilization should not exceed 80% than power supply rated output?
In that sense can I fine with existing coolermaster 450w psu?

Anybody can pl help me
If psu calculator showing 300w requirement for computer and 350w recommended, should I use psu with 450w with 80+ certification which eventually give 80% output of rated capacity which is equal to 360w
So in this case I am plus with 60watts so is it fine to use 450w psu?
