I have just got a brand new Seasonic GX650 as a replacement for my Focus+ under RMA (Focus+ had a manufacturing issue that caused it to trip when it shouldn't) and I am still tripping the PSU when the graphics card causes power spikes. AMD recommend a 750w for this, but I was told a 650w that is decent quality would be enough. Well, it's not lol. Soon as a fancy effect(like an explosion) occurs on my screen, the screen goes black, fans hit 100% and it requires a hard reset. Before anyone suggests it could be my GPU, it's not. If I limit my GPU power draw so that it only pulls 150-180, this never happens (been running like this for 2 weeks waiting for RMA replacement). Even if I force the GPU to run at throttling temperature it's not happening. So I am after a PSU that is more than enough for this GPU and any future GPUs I may get, preferably overkill. Can someone spec me a 850w-1000w PSU for the following: Vega64 Ryzen 2700x x2 Crucial MX500 x1 3TB Western Digital Green Some corsair AIO I forget the model of Looking for it to be between £150-200. I'll sell on this GX650 to recuperate the cost.
