My BFG LS-450 Died, and now I'm paying attention to a lot more stuff, as opposed to just watts and cost-effectiveness.

My DFI X58-T3Eh8 RMA process is underway and I hope than when a replacement arrives, I will not repeat the same mistakes I made before. When I made the i7 upgrade from P45 i HAD to compromise somewhere. Sad thing was that I didn't overclock much, the LS-450 was just a stop-gap measure.

I am just wondering if you Gurus here might chime in on this situation: am I making the correct approach?

i was indoctrinated by PC Power and Cooling's commandment about single rails being the "be all and end all", it was only after being a regular troll here that I discovered the benefits of a "smart implementation" of multi-rail design. 3 rails seems like the sound platform for my the reconstruction of my pc, it simply makes sense to have three dedicated rails for three different component categories.

I am using an i7 920, 3 sticks of pc3-12800 ddr3, a passive 4550 from sapphire, two wd 640GB caviar black sata drives, and a wireless pcie adaptor. I think that with this motherboard, and the intended use, these products should suffice.

I use this rig mainly for work, school, and watching movies, so noise was a concern. Some might wonder why I got such a high spec mobo for my intended use, but I feel that the DFI BIOS is an invaluable tool for underclockers, green folks & the like.

For a gaming rig I would probably go with a Zippy, but I don't want my bedroom to sound like an airport. So what do you fellas think?

A 525W Pro82+ for the current setup, assuming I don't need to upgrade for a while of course, or 625W for some leeway and some future flexibility...OR... 720W infinity, which, even though it exceeds my requirements is only a few dollars dollars more at buy.com (http://www.buy.com/prod/enermax-infiniti-ein720awt-atx12v-eps12v-power-supply-720w-enermax/q/loc/101/204224892.html)

any ideas?

The number of rails is insignificant when it comes to modern PSUs. It doesn't matter if the PSU has one rail or ten as long as they are balanced properly. From a practical perspective, neither the single-rail or the multi-rail approach has any real advantages over the other.

The 525W PSU would be plenty for your PC and would still have a lot of headroom left over considering the fact that you're currently running a very low-power GPU. There's no reason for you to go with a higher-wattage PSU.

A high-end single rail rail PSU's will always have one major possible advantage & one major probable disadvantage.

Possible Advantage: Improper load distribution either by poor PSU design or client having a very unusual system is impossible.

Probable Disadvantage: At +12V@40A and above, Over Current Protection (OCP) is unlikely to be effective. In other words a 1KW single rail will usually clear all shorts instantly by vaporizing a lan or something.

The unit referred to in my sig, below, was a very high quality, highly recommended +12V@50A PSU.

Multiple +12V rails exist for the sole purpose of safety, so that effective OCP on each rail will be effective in shutting down the PSU, when required.

As to size, we want to load between 40% & 60% of the rated capacity, never exceeding 70% for continuous operation. This provides the overhead necessary for cool, quiet operation and proper response to transients.

Best Wishes,

Can Enermax 525watts Pro82+ can safely handle my PC?

A good 400-450W PSU could even handle it fine.

edit: oh, I see you already got another thread running, same answers.
