I'm looking to replace my power supply since the one that came with my computer has a reputation for being unreliable and I've experienced inconsistent voltage, leading to random shutdowns. I currently have a 600w Apevia power supply. My setup includes an AMD Ryzen 5 7600 6-Core processor and an RTX 4070 graphics card, with 32 GB of DDR5 RAM.
I'm considering a couple of Corsair PSUs: one is the RM850e, which is fully modular and has low noise specifications, while the other is the RM850x with good reviews on quality. I'm thinking that either a 750W or 850W PSU would work for me. I chose Corsair because I've heard they're very reliable. If anyone has other suggestions, I'm open to those too!

Check out this PSU: [ASRock Phantom Gaming PG-850G](https://pcpartpicker.com/product/DKJp99/asrock-phantom-gaming-pg-850g-850-w-80-gold-certified-fully-modular-atx-power-supply-pg-850g). It's currently considered one of the best in terms of price-to-performance ratio!
A 600W PSU is technically enough, but you'll find that good quality PSUs at lower wattages are becoming harder to find. I recommend going for a 750W. I used to get the EVGA 650W for a decent price, but they seem off the market now. Generally, I stick with Corsair's RM-x series, but having a gold rating or better is what you should look for. You'll be fine if you follow that!
Either of the Corsair PSUs would be fine. Just a quick reminder: make sure not to reuse any modular cables from your old PSU. They can be incompatible.
I thought the new PSU would come with its own cables, so that should be fine!
Have you checked if the Montech Century II 850W is available in your area? It's a solid option if you can find it!
Yes, that's the one I was thinking about! I can see it on Amazon but no Microcenter near me.
Corsair is solid. I’d recommend the RMx models over the RMe. The RMx is a higher quality unit. For your setup, a 750W should be sufficient, but if the 850W is only a bit more expensive, go for that! It’s always good to have some headroom for future upgrades.
Thanks for the tip! I wasn't sure about the wattage since different calculators gave me varying results, but this helps clarify things.
