Hey guys, I'm trying to make a Mini-ITX computer for my Robotics Team so it has to be generally small and portable. The idea is a small, clear-case driver station to see all the hardware inside. It creates an awesome visual and a little show off to the other teams. The problem I'm running into though is that I can't stick a PSU onto the build because it's big and heavy. Is there a way to run it from something similar to a laptop battery? I don't know a whole lot or next to anything about power(I'm on the programming team, I tell the robot what to do and the rest is up to the electrical team). We're a bunch of high schoolers and this is a bit over my head. the total wattage for the computer as a whole is under 350W if that makes a difference.

Computer Specs:

  • ■ Intel Core i5-4570 Haswell 3.2GHz LGA 1150 84W Quad-Core Desktop Processor
    ■ ASRock H81M-ITX LGA 1150 Intel H81 HDMI SATA 6Gb/s USB 3.0 Mini ITX Intel Motherboard
    ■ SAPPHIRE Ultimate Radeon HD 6670 1GB 128-bit GDDR5 PCI Express 2.0 x16
    ■ G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600
    ■ Western Digital WD Blue WD10EZEX 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5"

Not exactly. I'm looking to know if I can run it from a battery. Similar to a laptop. The PSU converters and such are a nice help but actually knowing if I can power a 300W system isn't given. Thanks though!

Your system sucks a lot of power, so powering it will be difficult.

I would start by knocking down the wattage...can You pull the video card and go back to onboard video?

As for the battery...Lithium batteries are much lighter per Amp-Hour.

I'm sorry that I can not point You to a DC/DC power supply that will do what You want.
