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.

2. 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.

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

I'm currently using the 1KW OCZ ProXStream power supply on my new Asus P5B Deluxe Asus P5B Deluxe + E6600/E6700/Q6600. Once I figure out the P5B Deluxe, I'll come back to this thread for some proper system load tests for you all

The OCZ 1 kw seems not as long as the 1kw PC Power and cooling?

I wonder if it being smaller in size means it will run hotter than the PC Power 1 kw under full load?

eva2000

Yup much shorter at 150mm x 140mm x 86mm versus 1KW PCP&C SLI at 230mm x 150mm x 86mm.

But the 1KW OCZ ProXStream runs cool still so far from my testing

Excuse me for saying but is'nt it better to have a higher amp rating on each rail, 20amp for each rail seems way to low for a 1kw psu. I have a 500watt psu that has 40amp on each rail which is much better for todays hardware with dual core chips and multiple video cards.

eva2000

Not sure on the technical side.. I'm just an end user

But 20A is adequate it just depends on what the rail has sharing it's juices.

What psu you have that has multiple +12v rails with 40A each ? don't think I've ever heard of a 500W psu with such specs. Wouldn't matter anyway, you have to also look at max combined +12 rail amperage supported and I doubt' 500W psu with have a max combined amperage on all +12v rails exceeding 500W -/+ 5% otherwise it wouldn't be a 500W rated psu.

The 1KW OCZ ProXStream has max combined +12v rail of 70 Amps.

But bear in mind my above unit is pre-release beta unit, where final retail unit will probably have revised specs.

eva2000

Nice, the 1KW OCZ ProXStream handled my 920D@4600-4836Mhz on water Asus P5B Deluxe + Pentium D 2.8Ghz 920D > 4836Mhz



Next gonna try 955XE Presler to see if i can beat my previous H20 best of 4831mhz

alpha0ne

So is this just another FSP Epsilon but not as good, just like OCZ's other high rating PSU's ??
