power supply

I have a PSU for motherboard and a secondary PSU for GPU. Can I use 2 12v rails from separate PSUs? I know I'm going to get ridiculed for this question

Hi , i've got a new graphics card that requires more wattage than my current small form factor 240w PSU, and i've been wanting to get a new PSU but my motherboard : https://i.ebayimg.com/images/g/0-MAAOSwNoxkBut4/s-l1600.webp does have a 24-pin but instead it has a 6-pin and a small 6-pin. I...

Hey all! So a few months ago my PC started stuttering/hitching seemingly out of nowhere. I tried everything I could find online but nothing fixed it. I have switched every component in my PC, including switching my old drives to new ones, and trying OS with 2 new drives. I also changed my...

Is it normal for PSU to make this sound after I shutdown the PC?

Hi all I need your help in resolving an issue with my PC. I built my PC about 6-7 years ago, it had GTX970, some Intel i5 processor, 8gb DDR3 Ram, Corsair 750-Watt platinum PSU. About a month ago I started facing an issue with powering the system ON. I had to keep the power button pressed for...

They released a fan model called Hong Hua HA1225H12F-Z, which has a lot of bad reviews. People are looking for a replacement for it in expensive power supplies. Even found in Deepcool PQ850M. Can one of you write a letter to Hong Hua? Are there many of us like that?

How can I solve the fan noise problem with the DeepCool PQ650M PSU (R-PQ650M-FA0B-EU) ? Who else has come across it? Judging by the reviews, this problem occurs with many people. Other manufacturers also have a similar problem. But the squeak of the throttles is also added to it. Which PSU...

Hi all, I have been troubleshooting a GPU issue and though maybe I had a bad PS (Corsair RM1000x) at first. I ordered a second thinking the first was dead. For fun I moved ATX power to one PS and the CPU power to the other. PC didn't boot so I am curious how it knows it's not connected to the...

My pc has an issue when powering on. It goes on for about 1 second before turning itself off for about 1 second again then turning back on again by itself. This has never happened before. After turning itself back on it proceeding to operate normally with no other issues so far. My PC...

I have been offered a GIGABYTE AORUS GeForce RTX 3090 MASTER $800 Aud it's clean and when stressed tested by 3d and furmark does not go over 64 degrees. I heard about the vram issues but I only need something I can game on would it be ok?.

I have been facing a strange issue with my GPU as well as on-board graphics card. I have an Nvidia k620 that was connected to a monitor through the DP port. But it suddenly stopped working for no reason. In order to troubleshoot the GPU and monitor, I connected the monitor to the on-board...

A few months ago I upgraded to an RTX 4060 from a 1070. After a few days my monitors would lose signal a few minutes after boot, but the problem was fixed by reseating and dusting my connections. 3 months later, my monitors randomly lose signal almost immediately after powering on. I swapped in...

So short backstory, I built my PC about a year ago, February 2023 and it was dying a lot in an interesting manner. Freezes up for about half a minute and then black screen hard reset.. It was rare and I didn't think much of it. About 2 months later I upgraded to a more recent motherboard and CPU...

Hi gang, Amidst the many threads I see with 4080s not giving a display signal, I can't even get any lights on with mine. I recently purchased an MSI Ventus 3X OC RTX 4080 to treat myself after getting a new job. I am upgrading from a 3070ti. I made sure that the 4080 would be compatible with my...

I have an 3040 MT w/ i5 6500 + rx 460 and i want to upgrade to rx 470 but my power supply is 240w max output (PSU model H240AM-02) but i have no idea if that psu can handle it without blowing up, so what do u thinks guys

I have a small concern about my psu, I have a genuinely low power consumption system around 400w). The power supply I am using is the gigabyte ud 750 gm (750w), I am worried why the fan on the psu doesn't spin, the system runs fabulously with no problem and works well on though load, so can the...

so uh recently i had a power outage, and because of the stupid idiot that i am, i left the outlet plugged in with the cable, so after that, my computer started randomly shutting off and turning on, but its not the usual black screen thing, windows LITERALLY says "shutting down.." as if the...

Hi all, I recently built my first pc and I made sure everything went in the right spot. I tried to power on my PC but the only thing that turned on was the LED lights on my MB. I tried resetting CMOS and a bunch of other things but got the same result. I noticed that the fans on my PSU wasn’t...

If PSU calculators say that my build needs 350w then recommends a 850w PSU i think it's a big headroom for my build my question is what is the actual PSU wattage needed for the build to work very fine and handle all power spikes ? Build: MB: Asus Prime H510m-k GPU: AMD Rx5600xt CPU...

I recently encountered a perplexing issue with my PC after installing a new power supply unit (PSU). Initially, the system seemed to run smoothly after some stress tests. However, after about an hour of operation, the fans (possibly the PSU fan) suddenly ramped up to full speed, creating an...

Hi everyone, I've been having a couple strange problems with my computer and need to get it sorted out. Specifically, there are three main issues that I can't seem to figure out: 1. My computer frequently tells me that there are "not enough USB controller resources" when plugging devices in or...

I'm gonna try my best to put everything on the table with all the "evidence" of my pc being a little funky. About a year ago, I upgraded my old 2019 prebuilt pc with a better CPU, (a Ryzen 3, 2300x to a 5600x) and a new GPU, (gtx 1650 to a rtx 3070.) Everything was great, with games and media...

So I tried to push my power cord into the wall outlet and saw electrical sparks. Then the cord came out and I put it back in but sparks came out again so I quickly took it out, but the power switch wasn't turned off. After switching to another wall outlet, this time with my switch off, I turned...

I was wondering if 320w platinum power supply will work for GTX 970 ??

I was just curious if i use my type c port or usb port to charge my phone while gaming, it will use 15W(5v * 3A). So, will that reduce the performance of CPU or GPU because instead of power being used by them, its being used to charge

So we're trying to come up with our own CNC device. We want to use these components: 3 x Nema 23 stepper motors (3V, 3A) 1 x Nema 17 stepper motor (3.6V, 1.2A) 4 x TB6600 driver controllers (takes in 9-42VDC, outputs 4A peak) Limit Switches Raspberry Pi 4 other components down the line I want...

A week or two ago my computer started dying out of nowhere while gaming. It's not any new games nor settings and it still happens after having upgraded my GPU driver. I've been testing and monitoring and it seems to happen when the GPU has been at 76-ish degrees (celsius) for a while, so I think...

I'm looking for suggestions on the quietest components to support a PC with the following constraints. Don't worry about cost, I'm just looking for the best technical info: CPU: i9-14900K Power: motherboard will be set to enforce stock limits: PL1 = PL2 = 253 W GPU: Nvidia RTX 4090 RAM: 192 GB...

Hello, Is my PSU good enough to support my current setup? Recently my computer has been getting Event ID 13 nvlddmkm and crashing in games often (usually once every 10-120 minutes or so). After looking into it, the error seems to be related to the graphics card drivers/the card itself...

I can't decide what to buy since I can't find a clear winner, please suggest some good 80 plus gold fully modular 1000w PSUs.
