Few questions about new low-size/power build I have planned

post #1 of 8
Thread Starter 
I want to base the build around the Galaxy 1GB GTX460 WHDI (mainly so I can use a projector in another room without dragging cables). But a few questions:
-I'd like to use a 160W PicoPSU for the CPU, SSD, and mobo, and a 5.25" bay PSU for the GPU (to save space) - so if I connect the 6-pin connectors to the 5.25" bay PSU, there's still 75W of power from the PCI-e slot being provided by the mobo (and therefore the Pico-PSU), right?
-How would an i3-2100T pair with a 1GB GTX460 for 720p gaming?
-What's the maximum amount of power an average SSD and average optical drive can take each?

My main concern is that between the ~40W (under load) of the i3-2100T, the 75W of the PCI-e, the power required for the other motherboard components (RAM, miniPCI-e wireless card), and the SSD and optical drive connected to it, that the picoPSU would be too weak and fail or something.

The drive bay VGA PSUs weren't that great quality (jonnyGURU.com had two roundups), so I'd suggest you just go simple and get a single PSU that can run your card. What case were you planning to use? The 2100T should be okay for gaming, but you should just go with the regular 2100 because there is very little actual difference in power draw (silentpcreview.com reviewed the 2100T). The only time you'd want the 2100T is if you are severely power limited, such as trying to run off a 60W PSU.

Regarding the power draw of the 2100T, the 35W TDP includes the integrated graphics. Thus, the CPU by itself won't draw that much. An SSD will draw probably 1-3W. WiFi card will probably draw under 1W. Don't know what an ODD draws. GTX 460 can draw around 160W peak, I think, but the card you are choosing may draw a bit more, but "peak" means something like Furmark, and gaming probably won't run that close to peak.

Well the reviews of the FSP X3 I've seen say it's actually pretty good, and I'd assume that the X5, with the many good reviews on Newegg and it being the only such PSU still in stock, would be a good choice too.

In any case, if I do end up going with a traditional PSU instead, a quality 500W should suffice even if I went with a i5-2500 for the CPU, right?

Proper review of FSP Booster X3. Newegg "reviews" are just people saying that it worked for them, and are not "proper" reviews done with load testers and oscilloscopes.

The review said it was just okay. Biggest problem was the cost (very few watts per dollar) and the inability to handle higher temperatures without going a bit wacky.

I actually owned one, and I didn't like how the bracket bent when trying to plug in a power cord, plus it powered some GeForce 8800 GTS but not 8800 GTX at the time. Really strange because it should have been more than enough power.

If not overclocked, a 2500K CPU with a GTX 460 should only need around 300W of +12v power, meaning any PSU with 25A or more of continuous and combined (not added up, but true "combined") +12v power should work.

Let me ask again... what case are you planning to use? That might have a big part in determining what kind of power supply you end up with.

Sorry, forgot to mention, I'll be using a custom case, since there isn't any other case I'd like that meets my needs properly.

And I guess I'll use the Silverstone Strider Plus 500W, since that's the smallest fully modular PSU that's good as far as I know...and it matches the blue color scheme I'm going for.

Actually, now that I think...the Silverstone SG07 is only a bit bigger than the case I'd like to build, so I may save myself the trouble of building the case and buy it. I do want to swap out the PSU for the Strider Plus 500W anyway, and I'm sure it'll fit given the small size of it.

Have you looked into the Silverstone SG05 or SG06? Those are smaller than the SG07 and use an "SFX" sized power supply. The cases come with power supplies in 300W and 450W versions. I don't know about your particular card choice, but in general GTX 460 fit in those cases. In fact, the 300W PSU that comes with them are pretty robust and have been known to power GTX 460. The 450W version seems to have some QC issues.

BTW all of these cases (SG05/SG06/SG07) use slim optical drives.

I've never used an SG07, but have an SG05 and like it. The SG05 and SG06 are identical except for the front face. It can hold the slim optical drive, one 3.5" HDD and one 2.5" SSD/HDD.

Hmm, never thought about the SG05...and Silverstone does make a separate 450W SFX PSU if anything...but my only issue is that it's not modular, and there isn't a modular PSU that can fit in it AFAIK (and I want modular both for easier sleeving and easier cable management - I'd rather cut/shorten replaceable modular cables than something hardwired).
