Hello,
I have a working TYAN S2912E server motherboard (http://www.tyan.com/manuals/m_s2912_E_v10.pdf) with two Opteron 2347 CPUs and am considering to reuse it inside an eATX case for a small project. The mobo's manual explicitly states on page 32 that only the SSI/EPS12V (24 pin + 8 pin +4 pin) power supply must be used (ATX 2.X is categorically not supported and may do harm).
I don't want to spend a fortune on a PSU, so I looked around and ran into an offer of this Thermaltake unit: http://www.thermaltake.com/products-model.aspx?id=C_00002713. This PSU may be bought for 50 E from a local reseller who states that the unit is "Intel ATX 12V 2.3 & SSI EPS 12V" (http://www.bpm-power.com/it/product/1563216).
So far so good, but the unit has one 24-pin connector, and one ATX 12V 4+4 pin connector. I think I could easily convert the latter into one EPS12V 8-pin and one EPS12V 4-pin by creating an Y-split and using the right EPS formfactor connectors) to match the TYAN S2912E specs as described on page 32 of its manual. Then I would measure all the voltages and ensure that it all looks like SSI/EPS12V.
This PSU should be providing enough power for two CPUs and 3 HDs. TheThermaltake states that it will be at max of around 504W sustained for +12V with max continous power of 600 W.
Of course, I have some doubts about this strategy, and this is why I am placing a question on this forum before spending 50 Euros and/or burning the good mobo. Any hint/advice would be greatly appreciated, thanks a lot in advance!
Andy.
