I don't know about others but I did read it. It's good information.

People do have different opinions and thoughts, Why is it the PSU threads always go here?

Most people consider the PSU and a necessary evil and a place to cut the budget, they aren't the sexy part of the rig and don't express the same commitment like the Mobo, CPU, Ram and GPU's do, heck even the CPU cooling takes a more importantly sexy role. In reality I think most hear at SF would attest many a problem posted can be traced to a under performing or failed PSU. The fact remains that this is one key component that when running is easy to overlook but when failing or being pushed too far is challenging to diagnose. Like horsepower in a car or dynamic headroom in an amplifier extra capacity is a very good thing. I mate all my systems with extra wattage as well as stabilized UPS line power battery backup. For me it makes me feel safe knowing my system has clean, stable and plentiful power.....your mileage may vary.

Still, it's important to know that a good quality-made PSU is usually able to deliver its rated wattage 24/7 very easily as long as its internal temperature stays under 50C. If the temperature goes above 50C, then the continuous capacity diminishes - but of course it returns to normal when the temperature goes back down.

I personally only recommend PSUs to people that fit the above description. However, there are still PSUs that are safe to recommend that are rated for 40C. Some decent PSUs out there that can be recommended are even rated for 30C, but these are generally only recommended to people who are on an extremely tight budget, meaning it's so tight that they're already cutting corners everywhere else and can't afford to increase their costs by just a few bucks.

I think these are good threads, it is good to get different opinions. I just see that sometimes members get argumentative with each other. We are all here to help, and as the op said he has learned something.. so in the end it worked out

You're very welcome! I thank you for saying this because now I truly feel that I did a very good job here. It's a common belief that PSUs are all about wattage and nothing else, yet the wattage capacity can sometimes be completely ignored - especially when comparing something like a cheap peak-rated 600W PSU to a high-end, continuous-rated 450W PSU. The low-quality 600W unit in this example would have a +12V capacity of about 432W, or 36A but possibly even less while the high-end 450W PSU would probably have a +12V capacity of about 444W, or 37A. Not only that, but the quality of the power that the PSUs deliver would be almost total opposites (practically speaking).
