PSU requirements for my high-end gaming system

[andreas87]

Hello gentlemen,

Since I am an absolute beginner in PC hardware and components, I would like to ask you about the power/psu requirements for my new PC system.

System specification are as follow:

Intel Core i7-8700K | 6x 3.70 GHz, 12MB L3-Cache
Mainboard ASUS ROG Maximus X Code | Intel Z370
Graphic card: NVIDIA GeForce GTX 1080 Ti 11GB | MSI Gaming X 11G
RAM: 32GB Corsair Vengeance LPX DDR4-3000 | 2x 16GB
SSD (M.2 / PCIe) 512GB Samsung 960 PRO
Harddrive: 2TB Seagate IronWolf Pro
Optical drive: BluRay | Pioneer BDR-209EBK
Soundcard: HD-Audio Onboard
CPU cooling system: be quiet! Silent Loop 360mm | inkl. 3x Silent Wings 3

Is an 750 watt PSU (I chose 750 watt W - be quiet! Dark Power Pro P11) sufficient for my system or should I better play it safe by taking an 850 watt PSU?

I would be very glad about an informative answer from you!

Thank you so much in advance.

Andreas

That would be ample for your system. Its not a bad unit either.

Your system would easily run on 650, even 550W

Unit is decent
