HI! I currently have the Seasonic Focus GX750. Due to the new launch of RTX 3090 and the need for 3x8 pin i have chosen to upgrade my PSU. Some say 750 W is enough, some say 850W is preferred.

See this post i made on a thread over at linustech forum, and the answers it got.

I have:

mobo: Gigabyte x570 Aourus elite

CPU: 3900X, stock. Might go with 4900x once that launches. NHD-15 cooler, 2 fans

RAM: Trident Z neo 3600mhz 32gb (16x2)

GPU: Asus Rog Strix 3090 factory OC, 3x8pin 450w draw limit (currently have 2080ti)

Peripherals1: 5x 140mm fans, all the same(came with case),

Peripherals2: Razer huntsman keyboard, Razer viper ultimate mouse, Corsair and sennheiser headsets, wireless but they charge from usb slot every day

Peripherals3: Deepcool GH-01 A-rgb. GPU holder with RGB powered by motherboard.

Peripherals4: Odyssey G9 screen, and Asus PG27VQ Screen. I don't know if they draw any power for their usb hubs so i included them.

So that is my build. I currently have the Seasonic GX750w, and i am looking to upgrade.

Money isn't an issue (to some extent), i would like something that i can say is "one of the best" or "the best". And also it should be Future-proof with the wattage. I highly doubt i will ever overclock stuff myself, however i will be "chasing the tech" and getting new products in the next few years. I don't know anything about multi-rail, single rail etc.


What do you guys think? Appreciate the help!

I'd be shopping for a decent price on a Seasonic Prime Titanium 850 or 1kW. The Prime Titanium line has 20-30% OCP headroom and rock solid stability, which will go a long way to minimizing any potential issues from the 3090's high sustained draw and even higher transient spikes.

The 850W OCP doesn't kick in until >1000W and the 1kW OCP doesn't kick in until >1300W.

What would you say about
PSU be quiet! Dark Power Pro 12?

Edit: Big text? i'll leave it as is because it looks cool but yes, i am aware of my noob copy paste skills

Hahaha.

I don't really see anything to complain about except the price. You can get a prime titanium for $290 vs $400 for the be quiet! 12 1200w.

Pros for the Prime:

The Prime is significantly smaller.
Seasonic is possibly the highest end, most respected brand.
The Prime warranty is 12 years vs be quiet! At 5 years.
Seasonic will give you a free native modular Nvidia 12 pin cable if you buy a 3090 Founders edition.

If someone else has hands on experience with the be quiet! I'd like to hear their thoughts.

I've been using a Prime Titanium 1kW for years now.



Looking at the kitguru review for both, the Prime has significantly better stability while the Pro 12 has slightly better efficiency.

I've got a Seasonic Prime Titanium 1000W psu in my home server. It's a halo product. It's stability.
