Hi, I'm a low level-mid range gamer (I don't do anything extreme) and I am looking to upgrade my PC however in order to continue upgrading, im going to need a better PSU, and I need a PSU with a PCIe connector and at leats 500 WATT, is this one any good??
Well, the internet appears pretty lukewarm on that PSU. Some fan problems in particular are mentioned often. Personally I'm not a huge fan of the Thermaltake brand, but that's just because I have other brands that I like more. I would look around a bit and see what else you can find. But if you're set on it, it's not a bad choice as long as you save the receipt.
The rest of your system looks fine. 600W should be plenty of power since you're not overclocking.
