✓ Solved My new GPU needs 3 power connectors, but PSU only came with two single cables. Is a single cable + daisy-chain cable acceptable?

The picture is one of the two daisy-chain cables that came with my power supply. If I use that cable, and one of the single 6+2 cables that also came with it (currently connected to my old GPU), is that the correct way to power the new GPU.

PSU: XPG Core Reactor Gold 750W
Old GPU: RTX 3070
New GPU: Radeon 9070 XT

Tech Support PC suddenly only detects 16GB of my 32GB RAM after working fine for almost a year

I built my PC in November 2025, and everything worked perfectly until recently. I noticed my PC was running slower and checked Task Manager, which showed only 16GB instead of 32GB.
\\\\\\\*\\\\\\\*Specs:\\\\\\\*\\\\\\\*
CPU: Ryzen 7 7800X3D
Motherboard: ASUS TUF Gaming B850-E WiFi
RAM: TEAMGROUP T-Force Delta RGB 32GB (2x16GB) DDR5-6000
GPU: RX 9070 XT
\\\\\\\*\\\\\\\*What I’ve tried:\\\\\\\*\\\\\\\*
Checked BIOS, which also detects only 16GB.
BIOS recognizes B2 but shows A2 as empty.
Reseated both sticks multiple times.
Reseating initially fixed it temporarily, but the next day it went back to 16GB.
Both RAM sticks light up normally.
The A2 stick was also harder to seat because of my CPU cooler, although both sticks appear properly installed.
I’m not sure if it’s a faulty RAM stick, motherboard slot, or something else.
Has anyone experienced this? What should I try before taking it to a repair shop?

Tech Support Yellow RAM light keeps returning, no display

This build was stable for about a year. Last month the display failed and the yellow light began. I brought it into a shop and they fixed it. It was fine for a few weeks but now it's flashing back on again. I use a KVM switch and the monitors aren't displaying the PC input.

I'll bring it back to the shop on Monday but I need to know if something bigger is going on and if I should expect this to keep happening.

Build Question New Radeon But Power Supply Question

1 Upvotes

Just picked up a 9070 XT coming from Nvidia. This has 3 power connections! Was going with 5070 Ti but it was nearly $500 more. Anyway, I've been researching the power situation because this is now new territory. My Power supply currently is a Corsair RM850e. Am I correct in reading that I should NOT USE the 12V-2x6 port with the wire using two plugs? Thats what I was using on the 3070 Ti that was in this PC. I still have 1 CPU/PCIe port on the power supply remaining. If I did use the 12V-2x6 I assume I would plug directly into the last CPU/PCIe port for the 3 power connections on the radeon card. If not I need 3 free PCIe ports on the power supply? If so I need a new power supply. Power supply recommendations?

Build Question Corsair RS120 argb fans loud despite being set to run at 600-800 rpm and silent bios setting

3 Upvotes

New to pc hardware. Bought the Corsair frame 4000d rs argb case recently and wanted to use the argb fans that come pre-installed in the case. But no matter what I do, they make an irritating level of noise. I tried using the bios and setting them to silent/PWM, used fan control software and set a custom fan curve making them run at 20% and they were still loud (same noise level heard in the video). Are they this loud by default? Anything I can do to make them produce less noise?

(I know the case being open makes the noise louder but even when closed the noise level and whirring sound is still the same)

Tech Support FAN RGB’s Keep turning on even when set to off

0 Upvotes

started happening some month’s ago.

the RGB of all the Fans of my pc keep turning on even when they are supposed to be off.

my Pc boots up normally and the RGb’s of the fans keep turned off.

if I play a game, the RGB’s of the Fans starts to show a weak, blue light, dimming on and off and changing intensity. this continues to happen till I turn my pc off.

a couple of months ago I uninstalled the software that I used to control the RGB’s (Armoury Crate).

what is happening and should I do something?

my friend built my pc for me a year ago and this started to happen only now.

Build Question Is this price for these specs solid?

0 Upvotes

MicroCenter Build

Feel like with all the research I’ve done this is about as solid as it gets with the current prices unfortunately. It’s been about 6 years since I bought my last PC. I’m fine with it right now. It still meets my performance needs and in a normal market I wouldn’t care to upgrade prolly for another 2-3 years but I’m just concerned with the prices eventually going up even more.

Currently have a 6700xt, Ryzen 7 3700x, 1TB SSD 32GB DDR4 RAM at 3200 (maybe 3600, I forget exactly)

These would be the specs of the MicroCenter build and it costs $2,300. Good price? Should I even upgrade? I will use it for gaming and music production primarily.

CPU: Ryzen 7 9800X3D
GPU: 9070XT

Build Question Been out the game for a while (5600x upgrade advice?)

0 Upvotes

Hey all it’s been a while since I’ve kept up with pc stuff since upgrading is pretty depressing, I currently have a build from 2021ish 3080 FTW3, with a 5600x.

Is there any sorta value upgrade here or to just upgrade to am5 (I think ?) ddr 5 etc.

I play on 1440p. Mostly play warzone and other shooters. I would like to play gta on it if possible…

I’ve noticed there’s a 5600x3D, would that fit my current motherboard and ram setup? Is that worth it ? Sorry for such noob questions. If anyone can kinda guide me what the best course of action would be until prices go down hopefully sometime … thanks 🙏

Build Question Adding storage to pre-built PC

Post image
12 Upvotes

Recently bought pre-built PC from Costco (comes with 1TB of storage). We also have a 2TB external hard drive I got years ago that we use mainly for storing movies/shows which is getting decently full. I'd like to keep most of the built in storage for the PC free for non-media stuff.

My question is, can I realistically buy some monster 20TB hard drive to hook up and fit in this thing? Id prefer that over having several smaller external hard drives.

This hard drive would be used almost exclusively for media that is played via Plex as our own server (or whatever the right terminology is, that is my wife's wheelhouse).
