My current PSU is enough or should I changed?



yeah I clearly missed the nexb, my apologies.

While i don't always agree with Chugalug on PSU issues (most everything else I almost always agree with him), I find he is a very knowledgeable guy. Personally I'd be more comfortable with a Tier 2 or better PSU. However if Chugalug says you'll be fine, he is most likely right. The longer you plan to run it the more I might consider a tier 1 or 2 PSU.
