PSU for 1080ti and 9600k

[tony888]

Looking at getting a psu for itx system and was wondering if this would be enough juice:

i5 9600k
Evga 1080ti SC2

Looking at the corsair sf600 or the EVGA supernova 650gm

I, personally, would get the 650W - especially if you plan on overclocking either component.

Stress testing will probably push it close to 600W if clocking but full on gaming should be comfortably within tolerance with a quality PSU.

Or, this Antec is quality build and probably very similar price to the 650GM:

My basket at Overclockers UK:

• 1 x Antec EarthWatts Gold Pro 750W 80 Plus Gold Modular Power Supply= £96.95

I use a Super Flower LEADEX II 650W with same cpu and gpu.

550Watt is probably enough if they're both run stock.
I've got a 850 Modular for a similar setup, primarily as I want to reuse/futureproof it if possible.

550Watt is probably enough if they're both run stock.

550W PSUs seem to lack two separate PCI-e power cables, which isn't good thing for high power draw graphics cards.
Cables split in the end compromise stability of 12V and ground reference, because of doubled voltage losses to two separate cables.
