My recent venture into overclocking has led me to believe that my 550-Watt isn't up to the task anymore. It's an Antec TP3-550, made by Seasonic. I've had it for a little over 2 years and use it every day. For the most part, my system specs are updated. Long story short, in overclocking I get weird results and instability where others have had success. More often, stress programs/Windows freezes rather than spitting out an error. Also, not that I trust it 100% but I went here: http://extreme.outervision.com/PSUEngine and set in my config with 30% capacitor aging and it came out to 561 Watts. I think mine might be getting towards the beginning of the end. Anyway, I'm looking up PSU's and I like the CORSAIR 850HX (aside from the price ) but I'm concerned about longevity. I know it's a solid PSU made by Seasonic but how would it stand up if I'm using it 3 or 4 years from now with a totally new system? It's possible I might go SLI with a new CPU and overclock it as well. I probably won't ever have more than 2 hard drives though. I thought about this and looked at another option, the CORSAIR 950TX. I don't necessarily care about modular-ness but that thing has a lot of cables. I noticed JonnyGuru had a review on it and said it was made by CWT however looking at the Newegg pictures, it has the same UL number as Seasonic. I was wondering if anyone could comment on it, if they have one and could post the UL number? So my question would be, would the 850HX be enough for 4 years down the road with a higher performance system? Or should I go with the possibly lower-end 950TX? I dropped $90 on the PSU I have at the time and I hoped it would last longer and I don't want to make the same mistake.
