ya alot of guys are biased against them cuz they USED to put out crap psu's with no efficiency ratings
but now there are 1 or 2 types of thermaltake that are good...specificaklly their 80+ gold series that are used for servers and rendering computers.
but as a gaming psu i still dont recommend them....their tr2 psu's are terrible
I agree with this fella since I'm running an 80+ Bronze (supposedly Silver, but Tt had it downgraded) Toughpower XT 675 PSU. I got it since it was getting agreeable reviews across the board and is readily available in my country. I would have gotten something better, just for the peace of mind, but the model i wanted wasn't at the store so I had to resort to the Tt Toughpower XT. Anyway, it has yet to fail me.
Is it a safe bet to upgrade to that?, not just because of the extra 50W but for the 80+GOLD , flat cable modular and Haswell Ready..mine (the 1st linked above) is still alive n kicking for more than 4-6 years
