what were you doing tho? prime95 + furmark? you had alot of things in the system that didn't really need to be there. fans running at max etc... from the vid, it peaked out at 680w which is easily handled by an AX650. it only becomes a problem if it was like 700W+ for a few hrs for something like an AX class PSU. the question you need to ask yourself is the type of load you are putting on the system, is it just benching for epeen purpose? or actual gaming load?

I'd imagine the 650 might be able to do it, but I still feel safer with the 750 to say the least. As far as quality, these definitely have a look and feel of excellent build quality. The AX750 might have prettier wiring, but even the cables for this thing feel tough. Very happy with it so far, can't wait to test SLI biggrin.gif

seasonic X and corsair AX are of equal quality. you can pretty much use the them interchangeably and never notice a difference. biggrin.gif yah the seasonic X fan wont even spin up unless it reaches something like 40%+ load. quality wise, you wont find many consumer grade PSU that are better. maybe something like the kingwin stryker is alittle better, but not by much. they are pretty much built like a server PSU.

Well I have asked myself what I will be doing, and it's pretty much 24/7 folding in the background on my X6, probably at 4.2... assuming I end up getting a really tough board, as that killed my last one. VRM failure on actively cooled 8+2 frown.gif

Just moved my folding over to OCN too biggrin.gif I -might- fold on both 470's but my now-2-year-old and some change card, probably has taken enough beating from F@H. I will update you with exact power draw when my card, motherboard and cooling arrive. thumb.gif Have a wall meter (AVR) which displays realtime load on my desktop if I wish, so it's pretty easy.

EDIT: And I hate my hard drives going to sleep, and always run my fans full tilt. These BitFenix fans are really quiet, even off straight 12v. As far as the AP-30's go. NO. Hence the PWM mod, I can't STAND them at full speed LOL.

what PSU were you using before? there is really only 2 things that can kill your system after the burn in test. one is heat, which we all know what poor cooling can do. the other is poor quality PSU. a poor quality PSU causes brown out within the system components which is REALLY bad. your PSU is both the 1st and last line of defense against component failure so it really makes little sense to buy a poor quality unit. unfortunately most people don't realize that part of the logic biggrin.gif they just think "oh i need a 1200w psu and everything will be good" but i rather have a high quality 750w then a crappy 1200w since everything connected to the high quality PSU will be protected with the poor quality 1200w will still suffer from poor voltage control during sudden increase in load.

Silverstone Strider 750 Gold frown.gif The PSU is fine itself, minus the really toasted the EPS connector. The board was what failed, VRM just couldn't keep up. That, and it didn't throttle to save itself, thank you Gigabyte LOL.

Definitely hanging onto that PSU, even if I might not use it for my computer. Really large DC12 power supply is useful for many things biggrin.gif

and one more EDIT, lol.

I wouldn't bother with a crap quality PSU, did that when I was younger and it hurt, pretty bad. Lesson leared. Bad experience with a really old Rosewill 500w PSU back in the day. Luckily, that was not with this rig, lol.

yah I had a pretty expensive piece of charcoal with antec sticker on it back in the day too biggrin.gif after that I started doing ALOT of research into PSU's and decided for an extra $50, i could have saved the rest of my computer biggrin.gif been buying seasonic since smile.gif

Just an update, I recieved my second 470, though still waiting for a replacement motherboard that supports SLI. Popped the card into my old M4A board to test it, started up a GPU instance of FAH, and yep. This PSU hasn't even broken a sweat, after seeing it sort of LOL at folding on only the CPU.. and pretty much LOL at CPU + GPU, I have no doubt that it will have plenty of headroom for a second 470 biggrin.gif

Now for a motherboard... and a soonish update for power draw at the wall, as it is inaccurate at the moment since I also have a PS3 running a unit.

remember back when you said this?

(I also know that PSU calculators have to account for not all PSUs being created equally). But a little user input is a lot more appreciated than just a calculator. +rep'd.

wait till you see what the watt meter says at the wall when you have your whole rig together. biggrin.gif
