Hey, don't get the Corsair VS450. I have several of those in my internet cafe. They run good even with 24/7 use. I've had them for 3 years. However, they are really cheap and low quality power supplies. Some of the PCs won't turn on because of them. The fans will start spinning then stop, then the PC will try to turn on by itself, then stop again, it does that over and over again. I usually fix it by re plugging the cables and resitting the RAM. It's okay for me to do that occasionally since the PCs are only being used in the internet cafe. However, for personal use, I would not recommend it. Get a SeaSonic S12II or M12II 520, or an XFX TS 550 if ever you would get a new power supply.
