Corsair HX620 versus HX850 on OCCT PSU Test
Posted: Sat Apr 24, 2010 4:34 pm
I've never used the OCCT power supply test before, but just tried it out on my AMD test system... I'm not sure what to think of the results!
The test system:
AMD Phenom II X4 965 BE
XIGMATEK HDT-S1283 CPU Cooler
Gigabyte GA-890GPA-UD3H motherboard w/ BIOS F7B
4GB Kingston HyperX T1 DDR3 1600Mhz modules at 1.6V
ATI Radeon HD 5870 Video Card
Corsair P64 SSD
1x DVD-ROM
First up is the Corsair HX620W Power Supply from over 3 years ago:
Now is a brand new Corsair HX850W Power Supply that was just opened up and taken out of the box this afternoon:
Corsair HX620W Power Consumption:
76W Idle
196W Load w/ POV-RAY
Corsair HX620W Ripples:
3.3V - 59.33%
5V - 54.05%
12V - 8.90%
Corsair HX850W Power Consumption:
77W Idle
189W Load w/ POV-RAY
Corsair HX850W Ripples:
3.3V - 58.85%
5V - 1.05%
12V - 8.42%
How should I interpret these results? A ~60% ripple on the 3.3V rail would appear way too high... Is OCCT reliable for PSU testing?
