I would not buy the EVGA SuperNOVA personally, but again it's a matter of prefference. Buy what you like and what you think is the best bed.
I just ordered the Corsair Professional Individually sleeved DC Cable Kit, Type 3 (Generation 2) including AXI/AX/HX/TXM/CXM/RM, 2x 4+4 pin ATX/EPS, 6x 6+2 pin PCIe, 4x SATA, 3x Molex.
That supports the following:
AXI Platinum Series - 1200/860/760
AX Platinum Series - 860/760
HX Gold Series - 1050/850/750/650
TXM Bronze Series - 850/750/650/550
RM Gold Series - 450/550/650/750/850/1000
CXM Bronze Series - 750/600/500/430
Giving me a wide range of upgrade possibilities.
On a side note: Shilka and me are from the same country, but we do not agree upon this matter, at all to be honest. - There is one thread on the Internet towards the RM1000 - that is made my Shilka. - I do not call that proof I call it preposterous.
All cards have coil whine! Some more, some less but its always there as long as there is electronic circuits with coils!
An electronic circuit is composed of individual electronic components, such as resistors, transistors, capacitors, inductors and diodes, connected by conductive wires or traces through which electric current can flow. Like other inductors, a choke usually consists of a coil of insulated wire often wound on a magnetic core, although some consist of a donut-shaped "bead'' of ferrite material strung on a wire! Thus coil whine!
As i said before:"Coil whine is mechanical resonance of the coil with the frequency of the signal passing through it. Physically, a coil is just loops of wire, sometimes with a core other than air. If the frequency of the signal is in resonance with the physical wires of the coil, the coil may vibrate! The vibration is beyond human hearing but other times it's in the range of human hearing.
There are many electrical parts/circuits which can cause whining noises, so don't just assume you are hearing coils. Annoying buzzing/electrical sound(s) are unlikely to emanate from a coil - you have something else making noise. Whining is caused by a part (or parts) physically vibrating.
Unto itself, voltage is not going to cause a whining sound. Voltage is electrical potential (actually, EMF); current through a device is dependent on the voltage across it. With a GPU, changing the voltage changes the operating frequency of various components within the chip, however something is probably in resonance with the signal."
Well shilka IS our resident PSU guru, (not always right like you and me, we are not absolute all knowing) and like you he is entitled to his opinion! My opinion on the RM PSUs is they could have being built better, even Jonny Guru says it!
