Recently i upgraded my psu to something just a teensy weensy bit more beefy.
what i had: 300W generic PSU (brand name: Omni)
what ive got: 550W enermax PSU
for now ill ignore the wattage and current differences as it would be like comparing a ferrari to a skoda
differences noted:
1. product weight. the enermax unit is almost 3 times the apparent weight of the very light and flimsy omsi unit.
2. the enermax unit has 2 fans, rear and bottom.
3. fans are covered in nice looking gold coloured grills
4. many more (and much longer) connectors. the enermax unit also has 12V lines for the P4.
the old omni unit had 4 molex connectors and one fdd connector, so even if i wanted to add another drive i couldnt without a spare connector.
operational differences
1. fewer bootup crashes which seemed to be plaguing me. but they still occur unfortunately, final conformation that ive fried my mobo due to overclocking.
2. +3.3V line ,5V line & 12V are much closer to what they should be.
3. the voltages DONT drop as i overclock
4. the pitch change & rpm drop of the HSF fan is gone now. before if i went from idle to full load i could actually hear the whir/whine drop a note.
5. the 5V line doesnt drop either. a steady 4.92V, instead of 4.76 idle, 4.72 full load.
6. casefan speeds have increased some +50rpm.
7. HSF fan is now doing 4500rpm exactly, up from 4350rpm.
8. CPU temp is also a degree lower on average, probably due to the extra psu fan.
what i found most pleasantly suprising was:
9. noise of the PSU fans are impossible to detect, even with my ear up against the rear.. they are inaudible over the casefans & HFS fan.
and
10. despite the powersupply rating almost doubling, the expected heat output increase wasnt there... infact after a 4 hour stint at full load the PSU's heat output is far lower than the old unit. EXCELLENT for my conditions.
11. fan speed of the bottom psu fan also is monitorable via a independent 3 pin line, and at rare occasions it approaches 2000rpm. usual is 1700rpm. think my mobo needs another fan line
in conclusion i love this unit... and will keep it for years to come. course i could have probably lived with a 420 or even 350W version... but i needed the ego boost. and besides, with the way im going i can see myself with a watercooled unit and a peltier in a years time *grins*
