As previously mentioned, the NUUO is a bit longer than standard ATX power supply by about 15mm together with the modular mounting which takes up another 8mm. The top blower of my inexpensive Aspire X-Dreamer case must be removed to accommodate the NUUO. Yet, Lian-Li PC6X has no problem at all. Not a surprise, the Transformer case
has plenty of room left even when fitted with the original top blower.
A few of my test systems are preoccupied. The most popular DFI nForce4 Venice system would have been ideal for this test. So, here is what I could offer for test bed for the moment; sizzling 30°C room temp and low humidity making the test a bit tolerable without A/C running.Testbed:
AXP-M 2600+ Test Setup - Ambient temp during test ~30°C
|CPU || Athlon Mobile 2600+ @ 2.60 GHz 1.85v Vcore|
|Mainboard || Abit NF-7S|
|Memory ||1*512Mb PC3200|
|Other ||ATI 9000 Pro 128Mb |
Two Optical drives
80 GB PATA Hard Drive
1x120 mm radiator fan double duty as exhaust; 1x80 top blower
Cooler Master Aquagate Mini R120
Sunbeam Transformer case
With the overclock, the low power consumption test bed is estimated at about 292 Watts, although Sandra says the CPU alone is >130 Watts (I certainly don't believe that). (according to this online calculator
with none-overclocked CPU at 47W, the overclocked output is close to 100W !)Click to enlarge
The advantage of modular cable system allows the use of what is needed making wiring/cable arrangement easier than otherwise. However, working in a small area (unlike the huge Transformer case) will make the connection a bit difficult if the cables are not "pre-plugged" prior to mounting the PSU in placed. I chose to use up the "inner" plugs first and work my way "outward" in the event I add components later on.Performance
To measure the voltage, I use Prime95, MBM5 and a Sears Craftsman 82028 AutoRanging Multimeter. I first tested the PSU without the Fan Controller, which means the fans are running in auto mode.
All three rails are holding really good with very minimal jitter from idle to load in meter measurements; while more fluctuation with MBM5 which could be the result of how well the motherboard circuit is holding.
Next, I installed the Fan Controller with Temperature monitor which is the second center piece of NUUO. While I enjoyed the installation insofar, I can't speak for the Controller for a couple of reasons.
A) Using Sunbeam's own Transformer case the controller does not fit and can't be installed due to mounting incompatibility;
B) The power cable is too short to reach inside the case for connection.Click to enlarge
My curiosity in knowing how hot inside a power supply ended very quickly, as the monitor reached the high of 49°C after I ran Prime95 for 20 minutes and about 30 minutes of game play. During the entire period the fan noise remained unchanged bear in mind the room temp was rather high. I turned the dial up to maximum; the loud noise came through the air overcoming the sound of the 120mm radiator fan at 7 Volt. Auto mode is plenty good for me; and not knowing the temperature inside my power supply does not bother me at all, perhaps to some folks it matters I imagine.
Although there are two temperature sensors and connections in the Controller, there is only a single readout coming from the right connector located next to LED panel. The 49°C mentioned before was the heatsink reading while the second sensor located near the 80mm fan showed ~37°C.
The fun is over. Let me summarize my thought on the matter. ->
