Possible PSU Problem? Need Advice...

post #1 of 20
Thread Starter 
so basically, my rig is as follows:

i7 2600k @ 4.4ghz
Sabertooth p67 b3
16gb Corsair Vengeance 1600mhz
Gigabyte GTX580
OCZ 128gb ssd
Seatgate 1tb hdd
Western Digital 250gb hdd
LG bluray burner
Corsair H80 CPU cooler
Rocketfish 900w PSU
Antec df30 case

so this is my psu:

http://www.rocketfishproducts.com/products/computer-accessories/RF-900WPS.html

the full story is my computer was all working perfectly, but was running kingston 1.65v ram which i was recommended to replace with 1.5v, so i picked up the corsair ram and a bluray burner w/3d, when i replaced the kingston ram with the corsair, i booted up for about 5 mins and the computer turned off, went into the bios and realized that it was set for 1.65v to the ram and the kingston timings, so i set it back to 1.5 and reset the timings, then everything was working good, didn't use it for more then an hour or two at a time after.

last night i was playing swtor for about 4 hours and the computer just turned off, i booted it right back up and checked temps, then browsed the internet for about 1.5 to 2 hours and had no problems, i ran a mem test and everything came out good, i've also been playing around with and using 3d off and on lately as well since i picked up a 24" 3d monitor, i was thinking it might be the psu, it's about a year old, but sat in a computer i built and never used for most of the time, it's got maybe 50 - 75 hours on it. and is there a better psu to use on my df30 with the bottom mounted psu, or does it really matter?

the other thing i was wondering is i had a local computer sales guy try to sell me a $250 battery backup for my computer to regulate voltage going into the computer because he said the power here wasn't the best and he'd heard about people having problems running good gaming computers without one, any real truth to this? i never trust sales guys lol, thanks for any input.

sounds like getting an actual decent psu would fix your problem.

There are two kinds of battery backups. One is online (the one he's talking about) and the other is standby. I don't see much reason to get an expensive online UPS for a personal/gaming computer. If you had a mission critical server, then it might make sense.

where are you located? do you have brownouts? if not..the store guy is full of it
http://forums.anandtech.com/showthread.php?t=2065294 It doesn't look good for your psu...
aha! gtx 580..the power-suckingest gpu of them all..oops..that's the 480
The 580 is overloading the rail it's on, is my theory....
triggering your power supply's ocp....shutting down your comp
hey..at least the ocp is working thumb.gif
Here's a review of your power supply
http://www.hardwaresecrets.com/article/Huntkey-X7-900-W-Power-Supply-Review/1446/7

that's gotta be what's happening..gpu draws up to 363w @ load
12v rails on your PSU are rated @ ..just read this..
"Also, we couldn’t pull more than 21 A from each +12 V rail because the over current protection would kick in"
363(watts your gpu pulls @ load)>252(watts your psu supplies to it)
::sigh:: Yes..it's your power supply
..And i think the store guy was full of it rolleyes.gif

i'm in canada a town about 45mins away from edmonton alberta, and i remember the power going out twice in about the last 3 years, and ya i wasn't sure on the brand, but it's in the recommended psu's in this forum so i figured it might not be too bad, i used a psu calc from on here too and it recommended a 840w or 768 min, that sound about right? i'll probably just look for a 1000w corsair.

You don't need nearly an 800w or 900w psu. You would be fine with a 550w for your computer. A 750w would do for SLI 580's. The rocketfish was recommended on here? This would do fine: http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=7195038&CatId=2533

okay, i had a 500w in my old rig and it was just a dual core amd with 4gb of ram, 2 hdd's, and dvd drive, and an hd5770 and i got constant power warnings so i figured i would need alot more then that for my current one, and ya right up at the top under recommended psu's under the 900w section.

I see. That unit is supposed to be the Huntkey X7 900w internally. Even "good" units can go bad. Maybe the units that go on sale are not all as good or the same as what gets sold to people. It happens often enough in the psu world. besides the one review, I found several similar topics from owners of this psu with a quick search.

In all honesty that doesn't sound like a PSU issue... have you done any CPU+GPU stress testing?.. your PSU is a quality unit, that doesn't mean it can't be a defective sample, but I'd look elsewhere first.

i haven't done any gpu stress testing, i was working with prime 95 for cpu testing before when i was considering ocing a bit more but everything was perfect, but i've since just turned it back to the factory settings just in case, for the gpu, wouldn't it be more likely i would've had a problem before this when i was pushing out 3d, the night before i had the power down issue i was playing around for 2-2.5 hrs with everything setup for 3d, playing starcraft 2 in 3d, etc. i thought that would be alot heavier of a gpu load then swtor. is it possible running the 1.65v kingston ram until recently may have caused a problem with my cpu?
