Hi all,

I've pre-ordered the Lian Li EDGE 1000w 80 Plus Platinum Power Supply for my Lian Li build in preparation for the upcoming 5090 series cards. Specifically, I want to get the ASUS Astral GPU, and I wanted to know two things:

1. Does anyone know when this PSU will arrive - is it possible to get an estimate?

2. Is this PSU going to be enough power for my setup? The following is my build (except for the PSU and GPU parts, which will be used to upgrade the current components, which are an rm850x and a 3080 ti.
  • CPU: AMD Ryzen 7 7800X3D 4.2 GHz 8-Core Processor
  • CPU Cooler: Lian Li Galahad II LCD SL-INF Liquid Cooler
  • Motherboard: Asus ROG STRIX X670E-A GAMING WIFI ATX
  • Memory: Corsair Vengeance RGB 64GB (2x32GB) DDR5-6000 CL30
  • Storage 1: Crucial MX500 1TB 2.5" SSD
  • Storage 2: Crucial T500 1TB M.2 NVMe SSD
  • Storage 3: Crucial T500 2TB M.2 NVMe SSD
  • Graphics Card: Asus ROG Astral OC GeForce RTX 5090
  • Case: Lian Li O11 Vision ATX Mid Tower
  • Power Supply: Lian Li EDGE 1000W 80+ Platinum Modular PSU
  • Operating System: Microsoft Windows 11 Pro OEM 64-bit
  • Case Fans: 8x Lian Li UNI FAN SL-INF 120mm fans
Partpicker says the estimated wattage is 954, and I wanted to know if this won't be a potential issue in any way.

1000w is should be absolutely fine, and is the recommended about. Remember this accounts for those using power hungry Intel CPUs. I don't know too much about the PSU, but I assume it is good quality. Your CPU is one of, if not the most efficient CPUs. Who knows if the 5090 will draw the full 575w whilst gaming or in your specific use case. The rest of the build won't use much power at all.
 
All the power supply calculators from all the brands ie asus corsair. recommend 1000w at standard for a ryzen 7 and a 5090. If you use the overclock toggle on the calculator most if not all recommend 1200w. Not saying that's true but that's what they recommend
 
I've just decided to get the same 1000w lian li edge platinum. Do you think I should be OK with a 9800x3d, 360mm aio, mini itx motherboard, 5090, 2 ram sticks, 2 m.2 ssd and 3 case fans assuming a bit of overclocking?

Fair enough. I've decided to go for the 1000w as the psu is actually capable of 1100w, but i do have an itx board and less fans compared to yours.

Correct - I made a mistake in my OP, I actually have x11 lian-li fans not x8 on my case, and tbf, the price wasn’t crazy different between the 1000 and 1300 but yeah we’ll see.

I’m below 200 in queue for the 5090 on **********, but at the rate it’s dropping I think it will be 6 months before I get my hands on it

Just because a psu can deliver more than it's rating doesn't mean it's a good idea. It will be highly inefficient and won't last long if being consistantly abused like that. A psu is typically at it's most efficient around 50% load and starts tailing off quite quickly once past the 65-75% range. Constant high loads will also generate more heat and that will cause the fan to ramp up, something you don't really want to happen with this psu as going off the reviews it can get quite noisy.

Noted but 1000w is sufficient for a 5090 and 9800x3d setup.
