Can't decide on a PSU for workstation build

Recommended Posts

Posted · Original PosterOP

Hello everyone! I'm building a new system intended for workstation use (I won't be gaming at all). I work with 3D animation/modelling/sculpting, 2D animation (vector/raster), video compositing/FX, digital painting, image processing with Python/ImageMagick/OpenCV, etc. The apps I use are Blender, DaVinci, Corel Painter, Clip Studio, OpenToonz among others.

 

CPU: AMD Ryzen 9 3900X

CPU Cooler: Noctua NH-D15 SE-AM4

GPU: GTX 2070 Super 8GB
Motherboard: Asus TUF GAMING X570-PLUS ATX AM4
Memory: Crucial Ballistix Sport LT 32 GB (2 x 16 GB) DDR4-3200
Storage: Samsung 970 Evo 500 GB M.2-2280 NVME
Others: 3x Case Fans (no RGB) / 1x SSD / 1x HDD
Notes: I won't overclock

Estimated Wattage: 484W

 

The PSU's on my list so far...

  • Seasonic FOCUS Plus 80+ Platinum (550W)
  • Seasonic PRIME Ultra 80+ Platinum (550W)
  • Corsair RM550x 80+ Gold 2018 (550W)

I already had suggestions not to go with either of the Seasonics (I don't know why though). When I added the FOCUS I got this message on PCPartPicker... ?

The Asus TUF GAMING X570-PLUS ATX AM4 Motherboard has an additional 4-pin ATX power connector but the SeaSonic FOCUS Plus Platinum 550 W 80+ Platinum Certified Fully Modular ATX Power Supply does not. This connector is used to supply additional 12V current to the motherboard. While the system will likely still run without it, higher current demands such as extreme overclocking or large video card current draws may require it.

I admit to some brand loyalty between Seasonic/Corsair over habit but I'm very open to any suggestions, I already use an RM550x from some years back in another build but I noticed now they list it as RMx 2018, is it the same PSU?

 

Should I go higher on the wattage?

 

My budget for the PSU is £130 ($150 ish) but I have wiggle room, I'm looking for long-term reliability, trusted build quality and efficiency but I don't know how to look for it, it's the most difficult and scary component for me to choose, thank you so much in advance for any advice!

The focus has problems with transient response, they fixed on the GX model but not the original focus. The prime is actually quite good, but usually overpriced.

 

It's hard to go wrong with the RMx. The one you're looking at is among the best in its price range (assuming USD)


I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k (won) - EVGA Z370 Classified K - G.Kill Trident Z RGB - Force MP500 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G2 650W - Black and green theme, Razer branwashed me.

Draws 400 watts under max load, for reference.

 

Linux Proliant ML150 G6:

Dual Xeon X5560 - 24GB ECC DDR3 - GTX 750 TI - old Seagate 1.5TB HDD - Dark moded Ubuntu (and Win7, cuz why not)

 

How many watts do I need? Seasonic Focus threadUserbenchmark (Et al.) is trash explained, PSU misconceptions, protections explainedgroup reg is bad

I wouldn't recommend the Corsair CXM or VS. the CX would be adequate, but honestly anything TXM and up is ideal.

 

There's more to it than brand and 80+ rating.
