SSI CEB : first use

[XZed]

Hello,

I'm studying a next upgrade : will keep current ATX case (Sonata III) and try to setup dual Xeon on it.

Even if SuperMicro has some Dual Xeon ATX boards, i found right now a board model matching more with my needs : Tyan S7002.

I didn't notice this because i searched filtering non ATX boards.

But, i found that SSI CEB form factors only is 1 inch larger/deeper and has all the same mounting holes / io connectors positions.

So i measured the interior of my Sonata III case and a SSI CEB board would enter correctly (unless i'm wrong).

What i'm afraid is mainly about power subjects :

- I read many articles about EPS 12v : resuming, could we consider that a PSU is EPS compliant as soon as it has 8pin connectors ? (Antec EA-500D has 24 + 8 + 4pins).

- Tyan specifies :

Power SSI 24-pin + 8-pin + 8-pin power connectors / EPS12V

Does it require a specific PSU or any ATX one w/ 8pin connectors are sufficient ?

- I found that front panel is a "SSI 24pin" one....

Could it be used w/ classic front panel connectors ? What is the minimal cabling required ? PWR/RST ?

- Opting to a progressive upgrade, i planned only using one CPU for the moment and then, upgrade to 2 Xeon replacing, by the way, the PSU.

Indeed, i have read some Patrick's articles and thought that a dual socket board could be used w/ only one 8pin connector if only one CPU is setup :

One important note to those not familiar with multi-processor systems is that many consumer PSUs are not going to be suitable for use with multi-CPU setups because they have only one four or eight-pin PSU connector. Dual-CPU motherboards generally require dual 8-pin CPU power connectors so users looking to build a DP system, or looking at potentially upgrading in the future from a UP system should look for a server PSU (versus a consumer PSU) with dual 8-pin connectors even if redundancy is not required. This saves a lot of troubleshooting headaches or the need to re-wire a setup.

But i read this :

TYAN S7002 supports EPS 12V/SSI
power supplies. All 3 connectors
must be used.

Unless are they referring to a full dual xeon setup ?

Sorry to ask such questions but i prefer taking care for such a setup.

Thank you.

Sincerely
