Help Me Decide if i should go for this PSU

I can get an amazing deal on it (45 dollars after an MIR) and I know thermaltake makes decent stuff. It has every single connection i need as well as cables that are already coated black. Seems like a solid power supply to me.... Does anyone see any problems with it?

If 550W is enough for you i'd say its a really good deal for 45 after MIR. 

well im on thermaltake... and it's 6 years old. cant complain tbh

That's basically where I was at with it. Yes, 550w is enough because I think the most powerful card I'd really even get would be a 7870 tahiti le. I'll have to think it over for a day or two.
