what do you recommend for a full modular PSU - Page 3

Anyway, if you want fully modular units, you don't have a lot of options.
- Corsair AX or Seasonic X (same units, different stickers)
- Silverstone Strider Plus or Strider Gold units
- OCZ ZX
- Enermax MaxRevo

All of them are very good, so whatever offers the best value for your money would work... also like other people have said, 1200W is downright silly, you'd be very comfortable on 850W. As in, that's overkill already.

And I wouldn't get the SeaSonic X over the Corsair AX because you can typically get the AX for the same price or less, and Corsair has a 7-year warranty instead of 5.


You think CORSAIR Professional Series Gold AX850 would be plenty of power for 2 loops including 2 ek blocks on the 6970's, 2 pumps, 2 rads 1 triple and 1 double, couple fans, 5 HD's?



If so I would be happy to go with an 850 vs. my 1200.

Believe it or not you could go with as low as a 650w, but yes an 850w would be perfect in my opinion.

Some of you have probably seen this already, but here's an experiment I did for power consumption on my sig rig.

Stock:

Idle: 174W
CPU load: 258W
GPU load: 338W
CPU + GPU load: 424W

CPU OC:

Idle: 196W
CPU load: 309W
GPU load: 359W
CPU + GPU load: 480W

GPU OC:

Idle: 174W
CPU load: 259W
GPU load: 357W
CPU + GPU load: 447W

CPU + GPU OC

Idle: 198W
CPU load: 311W
GPU load: 378W
CPU + GPU load: 496W

CPU + SLI GPU OC

Idle: 215W
CPU load: 333W
GPU load: 592W
CPU + GPU load: 715W

The PSU I'm using is the Enermax Revolution85+ 1050W which is rated 80+ Silver, I'm in New Zealand so AC input is 240VAC, which gives my power supply an efficiency of 85%-89%-85% at 20%-50%-100% load.
The figures in the results are the AC watts measured with a power meter, so actual system consumption is about 85-89% of that.

As you can see my setup with two GTX 570's OC and OC'd i7 920 just touched 715W AC (~622W DC) when under full load. So a 750W PSU will be plenty beefy enough for a setup like mine, you might even be able to get away with a 650W since loading both the CPU and GPU 100% is a pretty unlikely usage scenario.
Stock is stock frequency with all power saving features enabled (C1E, speedstep)
CPU OC is 3.6GHz @ 1.32500 vcore, 1.30000 vTT, all power saving features disabled
GPU OC is 800/1600/1950 @ 1.025v/1.000v
For Idle I let it sit on the desktop with no active windows for a minute and watched for the peak.
For CPU load I ran Prime95 small FFT for a minute or so and watched for the peak.
For GPU load I ran 3DMark11 GPU test 1 and watched for the peak.
For CPU + GPU load I ran both Prime95 and 3DMark 11 at the same time.

Hope that helps some people decide on their PSU choice.

I would say go for the AX850 or the X-860 if you want to go with gold rated. They are pricey but they are great power supplies.

Also in regards to rebrands of Seasonic I believe the only one that isn't a Seasonic is the AX1200 which from what I remember is actually made by Flextronics as opposed to CWT and Seasonic like the rest of the AX units.

Yes, 850W would be overkill for that. I'm not sure why you bothered mentioning the waterblocks and the rads since those are basically glorified chunks of metal that do nothing for your power consumption one way or the other All that matters here is your two pumps and the fans, none of which are major power hogs (unless you have those crazy SanAce 6000 RPM / 48W fans that sound like there's a helicopter in the room).
You'll be fine

You got something against high powered fans??? There is nothing better then the sound of 3000 RPM Scythe Ultra Kaze Also the fact that they will be watercooled does make a difference if OP is planning on adjusting the voltage cap. With the 69XX series the power consumption goes dramatically up when you go past the original voltage cap. If OP is not going past that voltage cap a 750 watt will work fine. If OP is going past that power cap then an 850 is what I would recommend.

Yea I remembered hearing that it was an in house platform so I looked it up and that's what turned up.

Silverstone Strider Plus series.

You won't need 1200 for two gpu's and a loop.... 750w at most.

The AX1200 IS the best modular psu on the market. but not because he is using it
It is overkill for most people and expensive, but worth every penny.
I wish they did a 900W unit based on the same platform.

Normally I would agree. It depends on if the OP is going to adjust the power cap on those 6970s. Their consumption goes up quite a bit if you do unlike most graphics cards. Because of that if he does adjust the power cap then I would say 850 for both of those cards.
