Didn' t any of the beta-testers use DAZ figures? Or were they instructed to use only Poser-certified stock content?
Since then, I never went cheap on the PSU anymore because that can cost you dearly.Wow! Have they screwed with the binary morphs! Whatever they did is just not good. It overheated, blew a cap, and took everything in the case with it. The computer I blew was using a cheap Enermax PSU that shipped with the case, and it cost me the mobo, memory, processor and even the video card. That's what keeps your system stable during 3D renders.
The quality and power capacity of your power supply is also important. This also depends a lot on the case you use, if it offers sufficient air flow during renders. Those will not take advantage of the 4-pin sockets. Even if the mobo offers 4-pin sockets, it's important to buy 4-pin coolers, for most are 3-pins only, which will still spin at a fixed rate. 3-pin sockets can only spin the fans are a fixed speed, even when the hardware needs more airflow. I strongly recommend mobos with 4-pin sockets for coolers, which allow automatic and real-time speed control depending on the cooling demands of your components. No matter what hardware you have, it's important to make sure your case has sufficient cooling to protect the components during extended rendering periods.
I have already blown 2 video cards (GTX 275 and GTX 480), and an entire system - motherboard, power supply, memory and processor, all fried during Poser renders. It's a conundrum, because slower machines will have to render for longer periods, so they tend to overheat and slowly degrade the components over time. 3D rendering is very taxing on the hardware, so it's not to be taken lightly. As for the causes, it is easy to assume that 3D rendering on such older machines can cause overheating, which shortens the lifespan of the components.
