Good to hear.
Although, I don't believe for a second that a 650W PSU would power all but the top top top end of specs, as stated above.
My 3GB 580 Phantoms in SLI coupled with the entire system would buckle with a 650W PSU.
Do the math.
Brush up on Watts and Amps required etc.
So yeah, better to be careful what you say. Some might even believe it.
*Pretty rude and presumptuous there. I'll reply with a suitably rude response.*
Oh yeah, coz SLI/Crossfire is a typical system
You also seem to have completely skipped my entire point - one needs to know what the user's spec requirements are before one recommends any PC component willy-nilly. But I digress...
For years 'PC enthusiasts' have been mislead by marketing from PSU companies to believe they need a much higher PSU rating than they do so people buy more expensive PSUs and upgrade more often. These mislead people then frequently offer mislead advice to others on forums and the misinformation spirals. In actual fact, CPU and GPU manufacturers constantly produce more efficient components so power requirements don't actually go up much, if at all, with every GPU or CPU development cycle.
I'd like to know how you do your maths because I actually monitor
real-world, load power draw using a reliable power meter on the PCs I've built and also from reliable and industry renowned technical sources such as The Tech Report. Not just estimates (which is essentially what your 'maths' is) or quoting some guy on a forum.
Power draw of the following
very high-end system under load:
Core i7-3820
Radeon HD 7970 CHz
CrossFire
16GB (4 DIMMs) DDR3 SDRAM at 1600MHz
OCZ Deneva 2 240GB SATA
= 545W. Yes. For the whole system. Under load. Also, as it's a mains power draw figure it actually includes PSU inefficiencies on top.

Would I recommend a 650W PSU for the above? Of course not. You want some overhead as no PSU is 100% efficient (though that is taken into account above as stated) and people swith such systems often have a couple of mechanical HDDs, water cooling, OCing etc. on top. But how many people have a system of the above spec? And if they did, I doubt they'd be on an AV forum asking which PSU they should get (no offence whatsoever intended to the OP). The above spec is one of the few times anyone would ever need a PSU above 650W, no matter what you've been led to believe by PSU marketing types or your rudimentary 'maths'
Anyway - Good to hear you've got a PSU - I just bagged a 1200W Platinum Modular PSU for £150 and was well chuffed. Arrived today.
Prob wont go in my build for a few months lol
Speaks volumes
