In order for the results from all current and future PSU reviews to remain fair and comparable, Overclock3D uses a custom built Power Supply load stress tester.
The tester will be placing the following loads on each of the Easycon XL's rails:
+3.3v - 20a Load
+5.0v - 20a Load
+12v1 - 10a Load
+12v2 - 10a Load
+12v3 - 10a Load
+12v4 - 10a Load
The results are collected from a Mastech MAS-345 Multimeter which logs its readings via RS232 to a PC.
Efficiency tests are performed by measuring the wattage consumed by the power supply at the mains against the power (in watts) consumed by the OC3D power supply stress tester. The results may not be as accurate as those produced by professional testing equipment, but will certainly come in handy when comparing several power supplies against each other.
Possibly the hardest part of any PSU review is summarising the level of noise given out by the unit. The threshold for what is considered 'noisy' varies from person to person and therefore what I may consider a quiet unit, another person may consider extremely loud. A common way to resolve this issue is to use a dBA meter to measure the units noise level, however this doesn't take into account the pitch (type) of noise emitted and whether it is likely to irritate end users.
For this reason OC3D records all power supplies at idle and load in wav format for you to make your own informed decisions. All recordings are taken at 30cm away from the PSU and outside of a PC case. You will need to remember that noise levels will be reduced by varying amounts once the PSU has been installed inside your PC enclosure.

At idle I found the TG700-U35 to be extremely silent with the 120mm fan running at a very low RPM. At load the fan speed increased to combat the extra heat produced by the components, but at no point would I have considered the unit to be noisy.
In my opinion, the TG700-U35 would be a suitable companion for a HTPC system and possibly even a silent PC build.
