Using Antec's calculator pushin TDP, Peak Load 100% and 4yrs capacitor aging throws me out a 258 w requirement.
Problem I'm so desperately tryin to solve is a want to add a 9600GT, don't get me wrong the initial build was for the living room and preforms so well I've moved it up as my main.

Vista's 3.4 score on my 8200 makes me sad tho. So I have scoured all over on what i can do to crank it up just a bit more, and of course since it's my main atm ampin up my gamings a given. The Galaxy 9600GT is a green model stating a 40% reduction on pull, and checking GFX power guide here on Tom's Hardware states 104w while pushing 3D with a 9600GT 512mb. So estimating the 258w pull as is upsized by (40% of 104w= 62w rounded*) i'm going to need atleast 320w some what ignoring calc of 4yrs from original pwr req. Now my baby's case requires TFX for the power supply to which I have also hunted for to no avail. And Galaxy's website states that this model card requires a 350w pwr supply. The Antec MicroFusion Remote 350 comes with a 350 watt TFX, and I'm tempted to buy it just for the power supply but that'd be kinda obsessive.

So I'm left feeling heart broken and looking for any possible assistance on resources for a 350w or better TFX Pwr Spply, even a conversion between form factors, I'll go ahead and say I already trolled over antec's website and couldn't even find TFX pwr spplys for sale.

I thank you for the reply, but that power supply while small for such is an atx form factor, and the review states that the power supply gets loud after 220w.

The power supply in the picture is almost a twin to the one residing in my system now, and is one I already noted as a replacement if needed down the road. Tiny lil buggers being a big pain, and a suprise considering how popular both custom builds/mods and Htpcs are these days one would think this wouldn't be such an issue. Considering at 1200w newegg has plenty of atx just for example, asuming 30% of that would leave 360w TFX being small but I'd have to guess over 30% the size of regular ATX form factor.
