PSU

I once had a PSU from SuperFlower, a 320Watt dual fan. It was decent, and silent. How about this one…

A 400 watt PSU was provided with this case

Some specifications

Model No: P4 SF-400TE



But what a disappointment! This one is really loud. Looks like some extremely cheap fans used with this PSU, possible a relabelled no-name PSU!

The voltage rails after running 3DMark to stress my system were:



You can clearly see on the first graph were I start up 3DMark.

What can we notice? Well first of all, the unstable Vcore of my Asus p4p800 Deluxe.... Besides that, extremely stable +3.3 V and + 5 V rails. In idle position, the 12 V rails is higher then most PSU's I had until now, reaching no “out of bounds” values. This had its benefit, especially while stressing the computer. All the other PSU's I had, dropped to 11.7 on the 12 V line, while this one only drops to 11.9. This can improves stability, especially when you are overclocking your system.

So, I installed my computer, looked at the included cooling and stressed the PSU, time for a conclusion I would say.
