Worth it for an HTPC? I know it's complete overkill, but the price is hard to beat. Seasonic 300W SS-300ET is $44...

Of course, optimal efficiency is in the 50% of rated wattage range, right? I doubt I'll ever be pulling more than 150W with an i3-3225 + SSD + HDD.

CX430 is $24.99 AR, maybe better suited.

Good catch - I noticed the CX430 after I posted my queston. Seeing as how it frequently goes on sale for <$20 AR, I might wait for a drop...

Yeah, it was just on that deal (with $20 VISA GC rebate) a couple of weeks ago. I picked one up and just installed it this past weekend. Its very quiet and I liked the way the wires are wrapped in the sleeves. I haven't had the chance to install the PC and have it run for a period of time to give any other feedback on it yet.

$26.99 AR for me guys :(

Either way, I already went for the Antec 620 for $29.99 AR a few days ago

Appreciate the mini-review nonetheless!

Sounds like it'll be perfect for a small HTPC... I'm not in a rush, so I'll probably keep an eye out for another sale.

I got in on this too. It was the final piece in my ultra-quiet, power gamer build. Great piece of equipment! Highly recommended at this price!

Not worth it. You're better off buying a pico-itx fanless supply with an external AC/DC brick.
You're not going to be pulling more than 80 watts absolute maximum with this setup.

I have the cx 430 watt in my budget gaming build and it was surprisingly quiet. Really good PSU, awesome price, and a great brand. Corsair has amazing customer service, I know from first hand experience and as a result i'd be willing to pay more just for the corsair brand name, they are just plain awesome! I'll probably pick this up for my friends budget build.

Will this work with a UPS that doesn't output a true sine wave?

Just an update on the CX430...Over the past couple of days, I've been heavily using the PC that it got installed in, leaving it on overnight for a couple of nights as well (with power saving options) and its stayed very cool and amazingly quiet. So far, the unit has been very nice! I'm now waiting for another deal on it so that I can swap out the PSU from another PC in the house that has been really loud and I'm not too confident on.

Thanks again, this is very helpful information!
