PRODUCT INSTALLATION AND TESTING
Mr. Bones is very impressed with how compact the GX 750W actually is. With the increased availability of high-performance mATX boards and quality small form factor cases these days, this PSU could be a real boon to enthusiasts wishing to build in a smaller chassis. He was also impressed by a video he saw in which this PSU was used to start a BMW M3. (You can see the video HERE
.) Neither of us would recommend that you use a PSU to start your car, but it is an interesting marketing tactic.
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.
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 all 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 measured voltages were very stable and very close to their respective targets and there was very little ripple on any of the rails. The fan was essentially silent throughout the several days of testing and, as one would expect from a PSU with this kind of efficiency, the Cooler Master GX 750W stayed very cool as well.
