I've had a pre-release beta 1KW OCZ ProXStream Quad PCI-E power supply since last month. Specs aren't final yet.
I just started to test it with my new Asus P5B Deluxe
Asus P5B Deluxe + E6600/E6700/Q6600.
Here's some preview photos and preliminary tests.
At first, I thought it was the retail version of 850W OCZ GameXStream which has quad +12v rails rated at 20A/each. However, I noticed this power supply seemed slight smaller than usual and the fan placement is different in that a 80mm exhaust fan is at the side instead of a 120mm fan at the bottom of the power supply which the GameXStream series has.
The 1000PXS measures 150mm x 140mm x 86mm !
Here's the 1000PXS Quad SLI power supply on the right next to 700W OCZ GameXStream psu on the left.
Here's a side shot of the 700W OCZ GameXStream (left) and 1000PXS Quad SLI power supply (right). Notice the 1000PXS has a double decker PCB layout to keep the power supply shorter than other 850W-1KW power supplies I have seen.
The 1000PXS Quad SLI power supply has the usual 24pin (20+4pin) ATX connector design, but now has separate 4pin and 8pin connectors unlike the GameXStream and EvoStream modular power supplies I have tested (which have a single 8pin connector which splits to separate 4+4 pin connectors). Below you can see the 24pin ATX, 4pin, 8pin and Quad PCI-E power connectors numbered PCI-E1 to PCI-E4.
The rest of the connectors include:
- 6x SATA connectors on 2 cables with 3x SATA connectors each
- 6x 4pin Molex connectors + 2x FDD connectors on 2 cables with 3x 4pin moldex + 1x FDD connector each
Test Results
Did some initial power supply tests. Now that I have a
Power-Mate power meter as well I also can measure real power draw from power supply. I used 2 psu testers for this and my trusty Digitech QM1538 digital multimeter.
- Ultraproducts.com Ultra PSU tester http://ultraproducts.com/product_det...&productID=242
- Antec PSU Tester http://www.antec.com/us/productDetails.php?ProdID=77203
These are just quick tests to ensure psu is okay to plug into a working live system.
No load DMM test
+12v = 12.08v
+5v = 5.03v
+3.3v = 3.330v
No load DMM test
+12v = 12.04v
+5v = 5.000v
+3.3v = 3.299v
Fan load tests
Here's some pictures of the fans I used to lightly load the 1000PXS Quad SLI power supply.
- 2x 120x38mm Delta FFB1212EHE 3A startup / 2A operating fans
- 1x 120x38mm Panaflo FBA12G12H 0.6A fan
- 4x 120x25mm XINRULIAN RDL1225S 0.18A fans
- 1x 80x38mm Delta FFB0812EHE 1.35A fan
Total AMP startup =
8.67A =
~104.04 Watts.
Total AMP operating =
6.67A =
~80.04 Watts.
Note: I didn't end up using the 60x38mm Delta 1.2A fan shown in pictures.
According to
Power-Mate power meter the above listed fans drew a peak of 118.2 watts at start up only and minimum of 92.4 watts with average of 92.4-94W.
I conducted three fan load tests:
Test 1: 1x 120x38mm Delta FFB1212EHE 3A fans = 3A
Test 2: 2x 120x38mm Delta FFB1212EHE 3A fans = 6A
Test 3: All listed above fans = 8.67A
3A fan load test
+12v = 12.03v
+5v = 5.002v
+3.3v = 3.299v
6A fan load test
+12v = 12.03v
+5v = 5.003v
+3.3v = 3.298v
8.67A fan load test
+12v = 12.01v-12.02v
+5v = 5.002v
+3.3v = 3.317v
