on newegg there are some pretty bad reviews witch seem pretty bad
Here's a post I had made regarding reviews you see on Newegg and such:
"Generally, PSUs reviews from sites like Newegg, Amazon, etc. aren't all that useful. Normally, they plug it in, and if it works, they either give it a positive review and sometime even over-glorified it or not post a review at all. And then people that do complain are usually a small number of people in comparison to the number of people who bought it.
DOAs can be explain by the handling of the shipping company from the time it left the manufacturing warehouse in China all the way until it finally reach your system. During the quality control everything ran fine, but due to possibly that the boxes that holds these units may have been drop numerous of times at Newegg's storage warehouse, shipping trucks, etc. something may got loose or even damage.
Then issues like PSUs failing in a few months time can be explain by certain quality control issues that have been overlooked (remember, they have to look at thousands of units. They are bound to overlook something eventually). For example, the robots didn't put enough solder on one of the joints. Even though, it did not have an immediate affect, over time, during heat/cool cycles, it may crack and fail. Or a batch of components are partially bad that didn't show any immediate signs of failure and is able to pass and slipped by QC test. It may take a few months or years for issues to manifest itself.
Of course, these issues can happen to any mass-produce electronics. Not just PSUs. If you want to get a good idea of how good a particular PSU is, it is best that you go review a competent, more professional review site. TBH, the understanding of the inner workings of a PSU of those reviewers (Newegg and such) are usually very little. Reviews sites such as HardwareSecrets, Jonnyguru, TechPowerUp, HardOCP, etc. are good."
Even some of the best build, server grade PSUs has some complaints on them; however, that does not mean it's a poorly design, flawed unit.
Anyways, here's a review of the PSU on Hardware Secrets: http://www.hardwaresecrets.com/article/Rosewill-HIVE-650-W-Power-Supply-Review/1460/1
It's most certainly better than the Thermaltake TR2-600 unit that you got which was an inefficient, outdated design, that didn't perform well electrically.
