Q: Does the Seasonic Platinum 1000w have ANY issues with coil whine?
Are there any chances of recieving one with coil whine or are they all very well quality checked for it ?
I ask becouse im going to be going SLI GTX 780's with my current rig. My CPU (3930k 4.6ghz 1.36v OC) accoridng to AIDA 64 can pull between 250 and 300w at full load. The 780's together have a TDP of 500w, so i need 800w at minimum. Giving head room for GPU OC'd , other devices, and enough spare wattage to not run at max all the time, im looking at 1000w.
1. I haven't heard any complains with coil whine on the 1Kw model. Mine does now whine at all as well. I've heard the issue goes with the 860w model, but the first version only.
2. 1 Kw is way too much for SLI 780's. I have had SLI 470's and Xfire 7950+7970's working just fine on a 750w PSU. The wattage you're calculating is based on a 100% load, which unless you're running BOINC/Folding, it shouldn't be that high. Also, even if it is 500w, you have a 250w headroom for anything else, which should be well within what a 3930k OC'd can eat, and anything else won't even consume even 20-40w of power altogether.
I went with a 1 Kw PSU because i plan to trifire later on, and i run BOINC, where my computer is never under 100% load. Add to that i watercool so everything i have is OCed to the moon and back, and you get a massive power need.
