What PSU should I use?

Hello,
I am currently building a home server/Media HTPC, and these are the component list
CPU: Intel J1900 Celeron
MOBO: ASrock Q1900-ITX Mini-ITX motherboard
RAM: 2 X Samsung DDR3 PC-10600 2 GB 204-pin SO-DIMM
HDD: WD 3TB NAS Drive
Case: DIYPC HTPC-Minicube-Silver

So the system only draws around 30W at maximum. Is it okay to cheap-out on PSU, by using something like $15 logisys 350W ones, or should I at least use descent Seasonic PSU that costs $40?

  1. Don't cheap out on it. Seasonic, XFX, Antec or Corsair it's up to you.
  2. Get the seasonic for $40

    Power Supply: SeaSonic 300W 80+ Bronze Certified ATX Power Supply ($39.99 @ Mwave)

    or this one:

    Power Supply: Antec Basiq 350W ATX Power Supply ($30.11 @ Amazon)
  3. will those cheapo ones wouldn't even support maximum load of 50W?
  4. Oh they will but I'm thinking a longer work time per day and you want it to last.

    The cheap ones may or may not work, usually depends on luck. But keep in mind that they are usually outputting less than they state. For instance the Logisys I took a look at only had 12a on the 12v rail which gives you a max of 144w for the CPU despite being called a 350w power supply. Also they like to use the terminology of maximum output rather than minimum so you aren't guaranteed a thing.

    Yes, I am actually very well aware of that. I once made a mistake of using a Prescott Pentium 4 system on a 300W cheapo-PSUs. Let's say it ended up in fire :(.

    However, that was a "Prescott" which was a power hog. The baytrail-based celeron system won't draw more than 50W even during maximum loads....that's why I can't decide :(. Plus I already used up all of my budget and all I have is about $20.
  7. If you can, try to scrape together an extra $10 for the Antec I posted. I just can't bring myself to recommend the logysis power supplies no matter how low the system consumption is haha.
