The ripple problem's been addressed in production units by using larger caps.
Go back one page in that same review and look at the cold tests. The temperature delta is much lower on every test. It's not as if the power supply runs hotter at hotter ambients. If it did, the efficiency numbers would be drastically different. It's because the PSU can't push all of the heat that's being pumped into it.
It's not as if the heat is not coming from any part of the PSU. Any heat that comes off of any PSU is from the power conversion itself. The "problem" in the tests actually come from the fan not pushing enough of the hot air that the PSU is sitting in out of the back of the unit. So this heat builds up inside the unit until only very hot air can be measured coming out of the back. Sure, this problem can be addressed with a faster fan, but the tests aren't realistic enough to justify ramping the fan up on this unit. Power supplies aren't typically the only exhaust in the system and constantly sucking in 40°C plus air. As it is, Andyson initially designed this unit to not spin a fan at all until internal ambient temperatures hit 50°C. I personally didn't like that idea, but do you think they would engineer a PSU that put out that much heat to run fanless until it hit the upper echelon of it's operating temperature?
Can you comment on the amazing results seen on the BFG EX-1200 in Tweaktown's testing? How does the EX-1200 differ from the EX-1000? Does it have beefier caps or something? Will the EX-1000 post as good results as the EX-1200 in its 'revised' edition?
If I were to pick a PSU today, would I be better served with the EX-1000 or the EX-1200? Anticipated load would be 3x Crossfire 5870 OC + PhysX card + i7 OC + 4-5 sata drives.
Shelf space. The PSU section at Best Buy is only so big.Why isn't Best Buy selling the EX-1200???
My psu crapped out and this is on sale at newegg
saynotobfg said:Pros: none
Cons: BFG Tech is out of business (no warranty)
Power supply internals are GARBAGE, may explode if pushed
Won't put out anywhere near 1000w
probably 1000 PEAK... and that is a stretch
Other Thoughts: Huntkey made?
Xion is not a well-known brand, but they are a good brand when it comes to their higher-end products. They sell rebranded Superflower PSUs, which are generally very good quality units.Xion is not really one of those "good" brands.
It wasn't crap, it just failed. That can happen to any PSU, including a good one. Granted, it wasn't a fantastic unit, but it was decent enough.Well the 850 was crap...
I bought this for $50 bucks refurbished from Geeks few month ago and it's still working well.
I jumped on that same deal. I've been using it in my Phenom II x6 system for the past month and a half. It's been great so far. You couldn't beat 60 bucks shipped.
