Hello everyone,

I need an advise regarding my custom build. Here main specs:

Case
CORSAIR CRYSTAL SERIES 680X RGB GAMING CASE
Processor (CPU)
AMD Ryzen Threadripper 3970X 32 Core CPU (3.7GHz - 4.5GHz, 147MB CACHE)
Motherboard
Gigabyte TRX40 AORUS PRO Wi-Fi 6: ATX, USB 3.2 - ARGB Ready
Memory (RAM)
128GB Corsair VENGEANCE RGB PRO DDR4 3200MHz (8 x 16GB)
Graphics Card
24GB NVIDIA GEFORCE RTX 3090 - HDMI, DP
1st Storage Drive
6TB SEAGATE IRONWOLF PRO 3.5", 7200 RPM 256MB CACHE
1st M.2 SSD Drive
1TB SEAGATE FIRECUDA 520 GEN 4 PCIe NVMe (up to 5000MB/R, 4400MB/W)
1st M.2 SSD Drive
1TB SEAGATE FIRECUDA 520 GEN 4 PCIe NVMe (up to 5000MB/R, 4400MB/W)
Processor Cooling
CoolerMaster MasterLiquid ML360 RGB TR4 High Performance Liquid Cooler
Thermal Paste
ARCTIC MX-4 EXTREME THERMAL CONDUCTIVITY COMPOUND
Sound Card
ONBOARD 6 CHANNEL (5.1) HIGH DEF AUDIO (AS STANDARD)
Network Card
10/100/1000 GIGABIT LAN PORT (Wi-Fi NOT INCLUDED)
USB/Thunderbolt Options
MIN. 2 x USB 3.0 & 2 x USB 2.0 PORTS @ BACK PANEL + MIN. 2 FRONT PORTS

The only use of this machine will be 3D stuff (modelling, rendering, simulations and so on). I will often have to leave the machine on for several days in order to render my job.

I made a calculation and it looks like the max power consumption will be around 920W (load wattage 850W).

Based on specs and main use which power supply you suggest for my build and why?

- CORSAIR 1000W RMx SERIES™ MODULAR 80 PLUS® GOLD, ULTRA QUIET
- CORSAIR 1200W HX SERIES MODULAR 80 PLUS PLATINUM, ULTRA QUIET

An automatic PCSpecialist pop-up suggests a 1000W power supply, but I'd love to understand what would be the best choice in terms of efficiency, power supply assurance and and (of course) bill payment :) I don't want to endanger some machine component or pay more than necessary in my bill.

I hope you can help me in my choice.

Thank you for your time!

If you've calculated 920W & go 1000 that's only giving you 20W headroom, so I'd say go the 1200 as this also gives you more headroom for upgrades in the future

Don't ever skimp on the power supply. It makes absolutely no sense to spend thousands on a high end workstation, only to start penny pinching on the PSU. You really do not want to endanger those expensive parts. It is simply not worth it, and of course investing in the PSU means a more efficient-running machine that is much easier to upgrade later.

That said, once you have a solid base like that, you can't go far wrong. I have had my Threadripper build since Dec and I love it to bits! I love it so much is is almost embarrassing. If you need it for your current workload, once you've got it, you will be wondering how on earth you ever managed without it.

All the more reason not to skimp on that PSU. You want to get the best out of that beast for many many years, after all.

I’m not skimping on the power supply. Far from it.

I don't care about the expense. I would just like to understand what is best for my machine in terms of efficiency. When the pop up on the site said 1000W fits well for me, I felt confused.

If my machine works at full load (920Watt, 20% of allowance included) is it better to have a 1000W or 1200W of PSU?

1200 as everyone has said, because you never want to push it that close to capacity & the configurator only thinks about now and doesn't account for upgrading and requiring more power a couple of years down the line
