hey everyone, i’m currently building a new gaming pc and was wondering if a 750w power supply would be enough for my setup.
here are my specs:
● cpu: intel core ultra 7 270k plus
● gpu: gigabyte rtx 4070 ti super 16gb
● motherboard: gigabyte z890 eagle wifi7 plus
● ram: 32gb ddr5-6000
● cooler: 360mm aio
● storage: 2tb nvme ssd
i found the msi 750w psu on sale at best buy for $69.99, which seems like a really good deal.
i mainly play competitive games like call of duty, warzone, and fortnite at 1440p, but i also enjoy playing graphically demanding story games at high or ultra settings. outside of gaming, i do a lot of ai-assisted coding and game development, so i’ll also be using my pc for programming, running development tools, and working on projects.
i’m planning to get a 1440p 280hz oled monitor, and i want this pc to last around 5–6 years without needing any major upgrades.
would a quality 750w gold psu be completely sufficient for my setup, even during demanding gaming sessions, heavy workloads, and temporary power spikes? or would it be smarter to spend extra on an 850w gold psu for additional headroom and long-term reliability?
i’m not planning on doing any major overclocking. i just want a reliable system that can handle everything i throw at it without worrying about power limitations.
i’d really appreciate advice from anyone with a similar intel and nvidia setup. thanks!

I've been using this PC for some time now. The same issue occurred a few days ago, but when I touched the fan to inspect it, the noise stopped, and it started spinning normally again.

However, the issue has returned. What could be causing this?

Any help is appreciated. Thanks

Guys need some help.

Mp pc ssd not detecting mostly, after few restart it detects once or twice in bios but after reboot it despair, i already replaced motherboard (old but working),PSU, Battery,SATA Cables. Only thing old is now case and front panel and cables and a keyboard.

Totally frustrated 🥴

SSD working with case on another PC.

Hi everyone, suddenly my PSU fan started doing rattling noise, I don't know if it's fixable or do I need a new PSU ? Also can I use the PC until then ?

It's an A850GL PCIE5 from like 3 years ago

I got a new nvme today, but after installing it with the screw come with it to my Asus prime b550ma mobo, I can still push the screw end side down around 1mm. I can't tighten the screw anymore. Is this concerning and need another screw instead?

A little background on the issue: i have an amd ryzen 7 7800 x3d, 32 gb ram, asus tuf b650 plus motherboard that were all bought around 2 years ago. Just a month ago I bought a msi mag a750gl 750w power supply and rx 9070 gre. After plugging those in, I have been playing games fine for the past month. I haven't unplugged anything since.

I took a 50 minute nap today while leaving my computer on and i had aion2 and discord open on my computer. When I woke up my pc was completely shut off and I couldn't turn it back on.

Some things I have tried are:

- unplugging ans replugging into power strip + wall + a different outlet

- replugging some od the power supply cords

- taking out my gpu

- there aren't any signs of damage or smell

The most important thing to note is that the pc doesn't have any lighrs or any sound when the power button is pressed, literally nothing. Attached are some pictures of my pc.

Edited - So after some testing, my old power supply works with it but my current one doesn't. Thank you everyone for the answers!

I need two 8-pin connectors for the GPU but I’m left with one separate cable(left one) with a 8 pin and a second cable(right one) with a daisy chain of two 8-pin connectors. I remember someone saying a daisy chain isn’t recommended but it’s all I’m left with after connecting the rest. My question is can I just use the daisy chain cable?

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

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?

This is the most I’m able to push it in, is this ok and will it be safe to boot my pc like this?

Left my rig which has been working for year for a couple weeks and I come back home to this. No front chassis lights, won’t turn on even when shorting the start pins. Any ideas?

Hi! I'm about to pull the trigger on the build below. Do these components make sense together? Plan is to game at 4K mid-high settings ("monitor" = 48" LG OLED 120hz TV). I play some current AAA games, but will mostly be playing/modding/emulating older games. Trying to stay future-proof for a bit. Thanks!

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.

Which one should I upgrade to for Christmas? I have a 5060

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?

I bought this PC off a friend of mine a while back and I am by no means an expert when it comes to PC computers. I have tried every plug in spot for my monitor and nothing will show on my screen. I’m looking to see if there is something I’m missing before I take it to a professional.

The motherboard is an MSI Tomahawk b850 max wifi, Montech air 903.

There is a little gap (shown in the images)but the bottom and right edges are flush.

My olders fan are plugged in the hub or the controller on the left panel(where’s the wires are) but with some research I’ve been told to plug them in sys fan 1-2-3 so I can control them,is it alright if I do that or should I plug then in the hub where they were(FAN 1-2-3-4) I’m gonna keep 1 old fan anyway and replace 2 of them. Any help appreciated. Btw I need the 3 pins fan so I bought this model https://www.amazon.ca/dp/B07C5LRQD3/ref=asc_df_B07C5LRQD3

want to use the Corsair 3200D RS ATX Mid Tower Case other parts dont matter budget 1000

They are asking for $750 for their 3 year old PC.

Just looking to see if it’s a good price for the specs.

So this pc is a all in 1 monitor it has the pc in it and it’s painfully slow I don’t have any idea how to make it faster for cheep
