I was looking at purchasing 3 x TPS80W power bus boards for a DIY case, giving me plenty of juice. (9A ± 12V), originally with 3 power bricks.
Although, there is a lot of juice, its only 60 headers. I’ve looked around for other options that provide the ability for multiple bus boards on a single PSU, however the -12V rail isn’t as juicy. Find most of them lacking in that department in comparison to the TPS80W.
2 x TPS80W still gives me 6A on the ±12V rails, which is still enough for my case requirements.
So I’m wondering if its possible to purchase only 2 TPS80W bus boards with 1 power brick and attach additional 3rd party bus boards (giving me more headers), provided I stay within the specs of 6A?
OR… would it be more suitable to get TPS30 MAX x 4 (6A) which gives me the same spec of the TPS80W x 2 (6A) but with 80 headers. With this option, would I need two power bricks or could these be chained?
The projected case size is 10U (9U + 1U) 168HP.
Anyone done this? Recommendations?
