Hello everyone, my first post although I've been lurking for years. I'm getting ready to upgrade my HTPC, to start I upgraded my PSU from an Allied AL-8250SFX that came with my old MI-008 m-itx case, to a Corsair CX430 (I know, but hey, $25?) in my newer Silverstone ML03. I was rather surprised to see the idle power jump from 28w to 34w, and load from 51w to 73w, that is with the optical drive now removed (it won't fit, going external to save power anyhow). The question that is really bothering me is, what was not getting juice before the upgrade? Is it just that the new psu is underutilized (for now) and is therefore not as efficient? Or was something being underpowered the whole time I was using the system? Was I inadvertently underclocking my cpu? Was that why my memory always seemed to be wonky? And on my PC too? Once I upgrade, I'm sure the psu will be more efficient, I don't think the old one would power my new build, or if it did, it would be stretched. Feel free to comment on that, and on my new build if you want, I'm open to suggestions! Thanks! btw, I was originally looking more for a psu in the 300w range, but I just couldn't resist this deal.
