so you think my PSU can handle that much power SUSTAINED? because unlike Corsair or Seasonic, Many PSU companies out there write down the MAX output, not MAX SUSTAINED.... and the fact that i got this thing for 60 bucks scares me...

 

Yep your psu can take that. But Ultra isn't the best so maybe get a new Antec, Corsair, XFX, Seasonic psu.

They only rate it like 100 above at max.

i know, i would have bought an antec earthwatts, or the Seasonic 650W from NCIX, but i didnt know about this when i was buying a PSU.. so i cheaped out and grabbed an Ultra PSU... next time im grabbing a modular Corsair PSU.. but the idea is to not buy a new PSU, so...

true... so.. a 750 W PSU.. drawing 600W from the wall, .. at 78% efficiency is..about 470W and if my 750 watt PSU cant put out a tad over half of its rated power, then i would get really pissed off.... but then again, iv seen some pretty silly things.. my old 350W PSU choked on itself and started restarting my PC in games at a load of only 120W

 

Unless you're pushing everything consistently to 95%-100% usage, you won't be pulling 600w all the time. (unless you're running furmark 24/7)
You'll be just fine....how old is that psu?

about a year old, since i built the rig =P and its pulling 600W not outputting 600W, its rated for output, but i just need verification that my PSU can output the close to 500W of power that i need to run this settup, also your Tri-SLI is uber smexy

 

Indeed...what was I thinking.

Pity Phaedrus or TwoCables isn't around...I'd go with what either of them said.

I believe you'll be fine...for how long, not so sure.

 

Well, your system is only really pulling somewhere between 300-350W when factoring in efficiency, so even on a sub-par PSU, you'll be perfectly fine.

indeed, i hear some pretty nasty things happening during PSU degrade... and i forgot to register the Ultra lifetime warrenty within the month... so i only get 3 years XD

 

ok been reading around and according to people it performs like a 460w so no don't crossfire until you get a new psu.

 

You're pulling 400w from the mains on a 78% efficiency PSU... that's only 312w besides the 5830 is supposed to suck between 25~200w so you should be good, but as already mentioned Ultra's are of dubious quality

correction, 400W at 78% effeciency = approx 320W output, so that means that a second one bumps up input to about 600W, and output is about 500W, (closer to 470W) so i think my PSU should at LEAST be able to push that much.. but what about PSU denigration, how much will that factor in? and how long till it cant handle crossfire? 3 more years?

 

alrighty thanks guys... so what do u guys think? is it worth crossfiring another 5830? it would beat GTX 295 performance by a nice margin, and everyone remembers that massive mofo am i right

, so for 120 bucks is it worth it?

 

It's not worth it with your current psu as it will most likely die and could kill the rest of your components. Wait till you get a decent psu!!!

Yeah the LSP series was one of Ultra's Ultra failures. They still use cheap oem's to this day so Ultra psu is totally out of the question for decency.

 

mate as long as you have the physical connections available, yep your power supply is adequate.

ugh... thats disgusting... man did i get ripped off... but i built the rig as a noob so whatever...but i wonder... will Metro 2033 max out my system ? cuz i still cant beat that game, it lags at the part in the tunnel, and i am an OCN member, i allways run MAX

well the PSU came with 2x6 pins and 1x8 pin... so i would need to use the cables supplied to make the 2x6 pins needed for another 5830

also, please fill in ur system spec

Where do you get your info? A psu can have all the connections it wants but if it's running cheap parts (like the Ultra) it will blow out if you use them.

No, no, not at all.

 

about the cables thing.. i think thats what happened with early Dell OEM PSUs during the Pentium 4 generation, the thing had like 8 SATA connectors, and a 6 pin connector, but they could barely run what they could connect to...

so whats the verdict? yes or no? crossfire? or no crossfire?

ill reply in a bit when i finish my works cited

 

It should work BUT it would be highly ill-advised to do so, why not spend the dosh on a better PSU instead (buy the card later)?

hmm ic.. well i was hoping that if it did work then i could grab another 5830, but i dont want to waste money for another upgrade, as i wont be until after graduation, i probably wont even be playing that many games throughout highschool so theres no point in upgrade all the time, ill live with what i have and save up 2K for a nice rig in grade 12 =P

ill get a GTX 980 and an intel 64 core processor with an Asus Uber Pwn ROG board.. and a really smexy 2 gajillion watt PSU from Corsair, and a Petabyte SSD from intel running with SATA 1TB/s speeds

then ill continue to play crysis 1 with it and get 40FPS

thanks for the help everyone !
