its a crap psu, it can;t make its rated power.
its only as good as a 800w psu. be warned.
errm, firstly even [H] point out the conclusion that it was decent enough and they tested at HIGHER than rated temps. 99% of psu's are rated to the figures on the box at somewhere between 25 and maybe, just maybe 40c. that was either in a 45c box, thats the ambient, the actual temp was shown to be way higher 76c exhaust temp, thats just the air, the components will be hotter than that and very few people live in 45c ambient temps. even the tests in outside 20c the temp inside was above rated. almost everything you read on every psu specs rating is BEST CASE SCENARIO, nothing more, nothing less. you will never ever see those amps/wattages in real life usage, not on this BFG< not on a pc power and cooling, or an enermax or an ocz. you can expect a high percentage of the "rating" your psu has to be available to you.
but the other side is true, most specs(intel being a big exception) quote, as you should be law, the theoretical absolute maximum load they can draw. again in real life situations you will never have every part of your computer drawing its maximum wattage. if your hdd and mem are maxed out to supply your cpu, your cpu is waiting on data, thats life. if you're gaming, your hdd's aren't maxed, your cd/dvd will be doing nowt and so on. Intel only propose "average" wattage usage and refuse to tell anyone on earth exactly what counts as average usage.
just to throw this out there, i'm wondering if the supposedly insane power draw specs of ATI's R600 is really a change in the way they are giving out technical stats, used to be average usage, now owned by amd, the number has jumped from average to maximum.
because theres no standard its very hard to really tell what chips use less power, which chipsets are more efficient and what psu you really need.
but have you ever wondered how people had 7800gtx's in sli in a shuttle on a 350w psu with overclock cpu and 2gigs mem? its all baloney, read between the lines and make a sensible decision on what psu to get.
if a quad core cpu and sli with loads of hard drives and 4 gigs of mem can run on a 600w psu now, why would you need a 1k unit? oh yeah, marketing
EDIT:_ read the temps wrong, exhaust was only 60c, but the components will be hotter. thats the first psu they've used their test setup on, so no control at all, if every single psu fails worse that would make the BFG the best available. atx specs call for all printed specs to be rated at 25celcius according to [H], i don't know if thats component 25 c or ambient. they went with 45c in the case as thats what high end computers system temps are(apparently) but people with hot computers should know their psu's won't perform as well at higher temps, but everyones current psu's already work the same. if you've got a 700w rated psu, and your case temps are 40c you won't be able to get 700w's, simple as that.
