Im glad you and your friend got lucky! Even poor PSU's can still perform, but the risk is mostly mitigated when purchasing a good quality PSU and thats the point of this thread. There will be exceptions, like my two Corsair units crapping out on me, just like a known poor brand working well over time...
Built my new computer this week. Put it all together, cable management and all only to hit the power button and no go. Connected a back up power supply to make sure it was the PSU and computer cam e to life.'
Went back and exchanged the PSU the next day. Disconnected back up power supply and was smart enough to first plug in the exchanged BFG GS series 450 watt and again no juice. Connected back up power supply again and get a totally different brand.
BFG really sucks. They should fire the idiot who is testing their PSU's!!
They did fire me this week.
What's your build? How do you know you weren't overloading the PSU and protection was kicking in? Failure rate on those PSU's are less than 2%, so two bad ones in a row is really odd.
Keep in mind that a GS-450 is 450W peak and only about 350W continuous. It only has about 25A on the +12V rail, so if you're running any kind of high end graphics card, it's not going to power up.
What happened to the Antec Truepower "new" 750W? It was on the recommened list and now it's not? I bought it because of the recommendation and the jonny guru rating of 9. It's a seasonic built unit with a 80 bronze certification. I got it off the egg for $89.99, why did it fall off the list?
I personally dont understand why the 520HX and 620HX were dropped actually. They are still plenty powerful for ANY single GPU graphics card on the market and their quality was top notch.
I decided to just go with Seasonic's X750 in hopes it will be better.
Graphic card length reference:
ATI Radeon HD 5670 - 6.7"
ATI Radeon HD 5750 - 8.15"
ATI Radeon HD 4850/4830/5770 - 9"
ATI Radeon HD 5850 - 9.5"(ST45SF PSU recommended)
NVIDIA GeForce 9800GT - 9"
NVIDIA GeForce 9600GT/GSO - 9"
NVIDIA GeForce 8800GS/GT/GTS - 9"
NVIDIA GeForce GTS 250 - 9"
matt, you read that review i posted of the fanless. able to do 600watts, while fanless i would image the 460 would be able to get to 650 or 700 fanless.. built like tanks!
