Need recommendation on a new PSU for 9950x3d and 5090

Yeah its funny when I built PC's 20 years ago I never cared, but now im getting to the point Im getting more picky. Now you got me thinking I should just go back and get the titanium. Or get the Noctua edition :ROFLMAO:

The 1600w Titanium is A+, the Noctua is A++. will you notice a difference between those and an A- rating? Who knows. I would think probably not.

Maybe, but I'm already knee deep in soundproofing my basement office, so lowering the noise floor I might just do that. Pack my desktop with fans and lower the RPM as much as I can. Working from home and having as much quiet as I can is just so zen. Though I might just be talking myself into this. LOL. Thanks for all the info. I'm suddenly rethinking all my wiring and setup after getting the 5090 now. Also making sure my room ducting it up to snuff. Since having a 1000w+ heater and my monitors and one I'm setup my sim rig. Its gonna be one hot office.

Hopefully it's got a window you can open in the winter at least.

But yeah, I guess you'd want supply & return ducts to circulate the air if this is basically a sealed off room.

If I was enclosed in a small room I'd take the radiators and pop them on the other side of the room. Brings the noise down even further and removes a bulk of the heat source.

The wall where I have the external radiators I was tempted to do it myself but there is stuff on the other side.

So after some more digging I found I can get the TX-1600 possibly price matched to memory express for the same price I paid for the PX-1600. So I might just swap those out. But since then, I realized in my fan thread that my case might be too small to fit the 5090 width wise. So I'm trying to see if I can buy a 90 degree 12V-2x6 cable now. But Seasonic makes it really hard to find a seller of their 90 degree adapter. And I'm not sure I would trust any 3rd parties. I did look at thermal grizzly's option but they are only doing pre orders for thier new monitor device.

I would just go vertical mount, but I plan to put in a SFP+ NIC so I'd have to give that up. *edit* reading your thread it looks like were both in a similar situation since you mentioned you have an SFP+ as well.

I am planning to add some insulated ducting in the ceiling that will route to my storage room and hook up with a temp sensor to a booster exhaust fan in the storage room. Thats where my servers live as well so I am hoping to put another booster in there that hooks to my cold air returns to pull heat out. If all this fails I might have to look into a mini-split down the road.

I like the idea of a remote setup. I am running core-line conduit from the storage room to my office, so I might have a look into run a few fibre optic display ports and HDMI's. Im already going to be doing that for my AV equipment to my TV in the rec room.

So I did end up getting the TX-1600 after a price match, and paid $12 less after returning the PX-1600 thanks to price matching! I did have to mount the 5090 vertically as there just was not enough room. Im just going to look at something like the O11D EVO XL in the future. Everything is alot quieter now. I just need to get some chromax fans to get that last little bit down.

I am having one small issue though. After I installed the Asus GPU Tweak software, it shows pin 5 is maxed on the 12V 2X6 cable at idle. Tried both 12v 2X6 cables with the Seasonic and different ports. No change. I think it might be a bug, but just in case I ordered a Thermal Grizzly Wireview Pro II. Also have a Kill-A-Watt on the wall and my system was pulling only 180W for the whole desktop at idle when the software says it was pulling 16.384A from one pin while 1A on the rest. As one last check I tried it in HWMon and it said the same thing. So for now I'm just going to keep an eye on it and see what happens.

Love the 5090 so far. In my small testing where my 3090 would be at 100% to render 140fps the 5090 is barely using 25% to do 165. So I'm very happy about that!

Did you try the Octopus cable? 12v cables are notoriuosly flaky.

I never used anything but the octopus cable. There are also leds at the connector. Should be red when system is off, and off when the system is on.

I haven't tried the octopus connector. I will give it a shot.

I figured the problem with 12v 2X6 was at the connector going to the card. Apparently 16.364A is the max reading. No weird temps or anything. Card is stable though.

I cant really see any LED's by the connector. But that could be because I have the card vertical. I tried to see on the backside of the card but couldn't see anything.

Looks great and glad to hear it’s doing everything you want!

I am not sure I would run the card with that much of a difference in amperage on the cables…that has risk of melted connector vibes.
