PRODUCT PICTORIAL AND WALKTHROUGH
Ultra also includes an ample supply (ten to be exact) of zip ties to help with cable management. As you can see, they also include five each of the two styles of mounting screws. I don’t know about you, but I’ve got gremlins under my bench that quickly grab any dropped items and disappear with them. Having an extra screw around doesn’t hurt a thing. The anti-vibration gasket is also a nice addition, though I’ve never been overwhelmed by their ability to reduce apparent noise. Again, though, it’s included and can’t hurt a thing.
PRODUCT INSTALLATION AND TESTING
For this review, Mr. Bones has chosen the following components:
MSI DKA790GX Platinum motherboard
AMD Phenom 9950 BLACK EDITION Agena 2.6GHz 140W CPU
OCZ 2GB (2 x 1GB) OCZ2F10662GK RAM
EVGA 8800 GTS 640MB graphics card
Western Digital WD3200 hard drive
Samsung SH-S203N DVD writer
Mr. Bones, while being very vain and shallow, has unimpeachable integrity and will be overseeing testing. Let’s proceed.
The X4 is a relatively simple PSU to set up. One really can’t hook up anything wrong; the connectors won’t allow it. The fully modular design could be a real asset in a cramped case or in the event one would need to tale the PSU out of the case, change some hardware, and replace it.
At any rate, the X4 went in this Panzerbox chassis without issue. In this instance I was able to make all the mobo/peripheral connections and then install the PSU. It was then a simple matter to optimally route the cables and plug them in to the X4.
Testing consisted of monitoring voltages from the +3.3V, +5V, and +12V rails while the system was at idle, and during multiple passes of OCCT on both cores while running loops of 3Dmark05. Voltages were monitored with a digital multimeter. Over several days of testing, including overclocks exceeding 22%, rails were rock stable and not one power issue reared its ugly head. The results are as follows:
The results were excellent and unsurprising, given the specifications. The +12 voltage was a little higher than I’d like to see, but still within the latest ATX spec, otherwise the measured voltages were very close to their respective targets and there was very little ripple on any of the rails. The fan was pretty quiet throughout the several days of testing, though not as quiet as one would expect from a PSU with this kind of efficiency. Also, exhaust from the rear panel was a bit warmer than I would expect from an 80Plus Silver rated PSU. I don’t quite know what to make of this and without the kind of detailed, reliable data one can only get from sophisticated testing equipment, I hesitate to speculate. I can say that the X4 performed quite well for me and I had no issues with it.
