PSU woes.
PSU woes.
In recent months my computer has faced several issues. It runs an X470 with a Ryzen 2600, an RTX2060 and 16GB of RAM, all powered by a Corsair RM750x. This machine was purchased a few weeks after the RTX2060’s release, when prices were still below the advertised cost. It feels like a long time ago. A couple of years prior, it remained under warranty, but the CPU stopped booting when TPM was activated. Eventually, I switched to AMD through my retailer, who confirmed the hardware was defective. They provided a 2700x, but it kept failing. I upgraded the cooling system and installed a Thermalritght Peerless Assassin, which briefly stabilized things, though occasional crashes persisted.
Time passed, and I upgraded to a 5800X and added more Corsair memory. The instability continued, prompting me to reinstall Windows from scratch after several years. Eventually, I tested a MemTest86 stick and discovered one of my Corsair Vengeance modules was faulty. I double-checked the slot, ensuring proper placement, and confirmed the memory passed warranty tests. After contacting Corsair via their online support, I received an RMA, which is now being processed.
Currently, my RAM is at 16GB, and Lightroom works smoothly—previously it would crash. The GPU performance improved significantly, especially with AI noise reduction, cutting processing time from minutes to under five seconds per image. However, running games like Doom The Dark Ages or CS:GO caused random crashes, which I later realized stemmed from using an incompatible adapter and a faulty cable.
I resolved the issue by replacing the cables and switching to Corsair’s dedicated leads. Unfortunately, these seem hard to find right now. I’m considering purchasing another brand’s cables for stability, but I want to avoid mismatched connectors. I also bought a Corsair cable from Amazon, only to find it was a low-quality copy, so I returned it.
Sorry for the delayed reply. I was feeling off when I posted and by morning my body had turned into something almost human again. Thanks for your responses. First of all, the UK site didn’t have what I needed, but it was in stock which was convenient. At £24.99 I would have bought it, but with the postage it jumps to £35, making it a bit pricey for just a cable. According to my notes, I’ve decided on a different approach. Jaslion, I’d have thought the same. I haven’t checked any of these PSUs before. Some have standard rails for each voltage, while others include filters or separate circuits per socket, which might limit their use. Looking at the cables on Corsair’s site, single cables are rated for 300W and dual connectors at the PSU side for 600W. I’m keen to see a disassembly of this PSU or maybe do it myself. You might be right that there’s been an issue with this unit all along. Even though it still has its 10-year warranty, I’m not interested in the hassle of returning it and waiting without a PC for a while. So I’ve started exploring alternatives. Seasonic 100W Focus is £119, Corsair RM1000x is £109. I’m leaning toward the Corsair but either would work well. Should I consider other options? Once I decide and install it, I’ll request a replacement if it doesn’t work or get back in time for a low-end build. I could run some tests myself, but honestly, I’m too busy. I’m confident Corsair will either test it themselves or send a new one. My thought is the effort and time aren’t worth it.
