PC Power & Cooling 850 ETX (SSI)

[Teknet]

Hi...new to the forums here...and in the process of piecing together a SLI system based on the A8N board. Been reading quite a few posts about the various power supplies being used. I was thinking about the PC Power & Cooling 850 ETX (SSI) which should be released towards the end of the month. Specs say it is a 4 rail PSU with over 60 amps available, but doesn't give the breakdown for each rail yet. I was curious if anyone out there has heard anythiong good/bad about this PSU.

Thanks!!

It's PC Power and Cooling. It's liable to kick ass and take names. However for the price this may be also a good option.

Thank's ribbon! The zippy you linked to looks great also...and it's just over 100 bucks cheaper than the PC Power & Cooling.

Here's a link to the pre-release info...forgot to put it in my original post.

850 ETX (SSI)

Whats the 4x2 pin connector for exactly? Wonder if this would fit in the Lian Li V-1200...

ETX SSI just as the name implys. It's for Serv/WS boards.

I've talked to the technical rep at PC Power and Cooling (Larry, I think...) about this psu for about a half an hour last week. The 8 pin connector is basically 2 12v 4pin connectors, since it is intended for use in a dual cpu motherboard. I told him I was thinking of getting one and what I would be powering with it and he simply asked "why?". He said the 510 sli is plenty for any single-cpu sli system. He also said that they could make an adapter for the 8-pin 12v connector for a small charge.
It sure does look bad, though.

So it sounds like I am heading for overkill and throwing cash away...is there generally a good power supply recommendation for an FX-55 SLI system with 2 6800 GT cards (BFG OC), 1 GB memory (Corsair XMS 3200XL), 3 SATA hard drives (74 GB Raptor & 2 NCQ Maxtors), and 2 optical drives (SATA DVD writer & SATA DVD)? I'm working on getting a good list together before I start ordering everything...appreciate suggestions.

Ammm yea.. its called the pc&c 510 sli

 

[govern1]

Like I said, the rep asked why I would spend the extra money on a psu meant for a dual cpu board. He said the 510 sli is more than enough. I run the 510 pci-e version (1 pci-e power connection) and have zero psu-related issues.

Thanks...do appreciate it!

If you don't mind looking at other brands the 520W OCZ Powerstream is a great PSU and it costs less than the pc &c 510 sli. The 550W Sparkle is also a good PSU for what you're doing.

A 4-rail PSU wouldn't even be compatible with single-CPU MBs. I mean, how would you make use of the 3rd and 4th rails? And of the remaining 30 amps on two rails, you'd encounter the current limitation on 2-rail PSUs, which is that any excess amperage on one of the other of the rails can't be used. It's possible that using the PCP&C 850 would NOT be sufficient to power an SLI system with two power-hungry video cards. How's THAT for ironic?

I have an almost identical setup but with 1GB more memory 2 74GB Raptors a 400GB Seagate and another 34GB Raptor, an Audigy4 Pro, Belkin Pre-N card, and a couple of thermal gauges and it runs beautifully on the PCP&C 510 SLI.

How I'd do is:

1 rail-mother board, around ~22A
1 rail Molex to video cards around ~18A
1 rail for drives around ~14A
1 rail for case fans water pumps ~6A

This would give great power and signal integrity to IC's.

Sounds good to me!!!

You can always parallelize the rails, so current is drawn from all four equally.

OCz Power Stream 520

I assume that since it has two PCIe graphics card connectors that they are targeting this at the nForce Professional motherboards that support dual CPUs and dual graphics cards.

Just a warning: The Zippy doesn't work with the DFI nforce4 boards...

I had been thinking about getting both ( i have a zippy 400w, that is pretty damn solid and is powering my 6800GT rig in SLI right now qith out a problem... but I am using the asus board)

Out of curiosity...why doesn't the Zippy work with the DFI boards?
