Multi PSU setup

post #1 of 4
Thread Starter 
Hey guys, I'm building a new case and I was planning on using 2 PSUs. Trust me that it's not what you think.

I am planning on using a MINI ITX PSU and a 5.25" bay PSU for the graphics card.

Now my questions and planned setup are as follows:

Mini ITX PSU will run these things:
Mini ITX MB
2500k
2 Dimm of memory
3 HDD
Corsair H60

5.25" PSU will run the graphics card, 2 6 pin power or more.
1 card only.


Now, question: How much wattage do I need for the core parts? i.e. the ITX PSU.
What do you guys think?

Not much, probably 350w at max. If you're not planning to OC then around 250w - 300w possibly. Also, Google "PSU calculator", and choose the first one. select your whole system minus graphics card and it will tell you what you need.

Every 5.25" PSU on the market is a piece of garbage. Get one of the FSP or SeaSonic small form factor PSUs, the 300-350W ones should handle up to like an HD6770.

That's about what I thought. I'll just make it a little bigger and use my regular PSU for it.

Thanks for your help.
