My old one, still in use, makes incredibly loud clanging sounds (as if the fan is cutting into a wire, even though it isn't, I've checked) and is dubiously unreliable. So, I need a new reliable and cheap-ish power supply, hopefully quiet too, but that isn't needed, and I thought coming here is the best thing to do since most of you have had hundreds of power supplies that have been over-used and abused until you've found a perfect reliable PSU. I don't need a very high power PSU, but around 600w would be fine.
I would personally recommend the Antect HGC 620w M to anyone, I have used it constantly for the past year now and have had no problems. It has a 5 year warranty, all Japanese capacitors, and over all a really good build quality. And of course it is 80 plus certified. On top of all that awesome stuff, if you delve a little deeper into its review it provides some of the cleanest power out of almost all power supplies. Well maby other then its bigger more expensive High Current Platinum brethren.
