My System Specs

Default (Power supply for) NUC-like build

Now that I have ordered parts, I am planning to assemble a NUC-like box (in function, not size!) for my mum, who has been using a tablet, but finds it incredibly slow; the dozen or so competing wifi signals probably don't help. But I need to obtain a few parts, namely a GPU-having sold my old one-and a PSU, the only spare I have lacks the requisite ATX eight-pin power connector (and is likely of dubious quality).*

FreeGeekVancouver sells PCIe GPUs for $20 or less, I only need VGA/DVI to connect an old DELL LCD, max resolution 1280x1024. The system will only be used for web surfing, (scanning and) printing off recipes, maybe Youtube, possibly as stereo, etc.

She might also need a wireless card, depending where the system is located. But I am steering here into using a wired connection, if at all possible.

PCPartPicker estimated the system (890FXA-GD70, Phenom II x4 970, 8GB RAM, etc) will use circa 265W without a GPU. However, some of the parts being utilised are so old, they aren't included in the site's database, so the 265W is even more of a guesstimate than normal.

FreeGeek's price list ranges from $11.50 for 350W to $30 for a 600W unit, plus $10 for modular cables.

What size is actually need, 400 Watts? A Corsair CX Series CX430 430W is currently only $35 (after mail-in rebate), or would a used, name-brand unit be fine?

* I am assuming there is no advantage to upgrading my existing Corsair Professional HX850W.

Have you already ordered those parts? Used deal? Depending what you get for a GPU will dictate how much power you are going to need. If you use something low end a decent 350w will be fine. From there it will go up. The cx430 would be fine for most mid to low end GPU.

Honestly for those uses I would have got a cheap AMD APU or intel pentium and used integrated graphics.

My bad! The parts on order are for my Skylake build, my soon-to-be-old CPU-MB-RAM-etc is being rebuilt into an old case for my mum; such an approach is far cheaper than even an AMD APU. Besides, as much as she complains about her tablet, I have my doubts whether she'll really give up it's portability/ease of use.

I might not even need to pick up a GPU at all, if the ancient PCI one I came across tonight, while rummaging through my old parts' box, looking for a PSU, works. It must have come with my turn-of-the-century VoodooPC....

In any event, probably safest to research 400-500W units (at jonnyguru.com), in case I can't find a super-low end GPU or this turns into something else down the road, a living room Steam-box perhaps?

Thanks Bond007

That makes much more sense. I just looked at current prices and the cx430 is what I would grab for your build.

With my main rig heavily overclocked, (4790K and GTX 780 Ti) I'm drawing 375W max at the wall when gaming. I could run a good 450W unit but not much cheaper than any 550W PSUs. You can run your box with a 300W unit like those Seasonic OEMs.
