this is a 20$ PSU I got off ebay a year ago,the Fans died this year I love the no user serviceable parts thats so BS >< Plus you need to open them up once or twice a year and de dust them depending on how bad your dust build up it. I have checked the rails they run nice all in all not bad for something I got cheap and modded ^^
As long as you wear protective clothing and let it sit for a few days you'll be fine. You dust out your PSUs????
anything above 300watt thats completely furry inside would you rather wait it it overheats and fries? I also dust out my Comp and its fans. I be a uber geek
