Is it my powersupply?

post #1 of 16
Thread Starter 
So I spent $1700 on a new rig and got everything new except my old PSU because I recently got it September of last year and it's a 850w, I thought it would do fine...
It's a TR2 RX 850w Black Widow ThermalTake PSU.


Here are my new comp specs:
Intel 2500k Sandy Bridge CPU
MSI P67a-g43 MB
GTX 570 SC
my old GTX 275
Intel SSD 120gb SDD (system)
1tb WD Black series HD (data)
2x4gb Patriot 1600mhz RAM
Frio CPU cooler
(all that wasn't 1700, I got some other stuff that I thought was irrelevant to post, let me know if you need any other specs)


So I got this rig set up two days ago and did some overclocking and had Prim95 running for 8hours+ with temps never exceeding 59c.
I also did some GPU overclocking and never had temps pass 85c.


But yesterday... some very weird things happened.
I was simply working on some Word documents and studying for finals when all of a sudden after LESS than 3 hours of being turned on, my computer froze. I restarted and began working again. In less than 2 hours, it happened again.
-I took out the GTX 275, since I only had it set up as a dedicated Physx card. I restarted again and left it on while I watched some TV - IDLE, nothing running at all. I'm pretty sure the time was 4:30 when I started it up. When I came back to check on it - at 6:10 or so, it was frozen and the time was stuck at 4:51... only 21 minutes had passed and yet it froze again.
I reset the GPU overclock back to stock settings and lowered my CPU multiplier from 45 to 40.
The computer ran from 8pm until 11:50pm or so when I turned it off and headed to bed.
It's only been on 30 minutes for now, and it seems okay so far.


I'm just trying to figure out if this PSU is total crap and is causing all this or not... it's really weird because everything was working when I set it up and I STRESS tested both the CPU and GPU for a LONG time (8 hours) and nothing ever crashed, but now that I'm not even using it... it's dieing on me. (freezing)


I burrowed 300 bucks from my dad so I can spend a good amount of money trying to fix this, but I don't want to buy a new PSU only to keep having the same problems... and to my knowledge, there is no way to stress test the PSU or something like that, so I'm trying to see what you guys think.


IF this problem is caused by the PSU, I was thinking of getting this:
http://www.newegg.com/Product/Produc...D=a63rwyqt3d9e
OR
http://www.newegg.com/Product/Produc...D=m7v63b1axb71


Price is the same because Corsair has the 10$ rebate + FREE shipping which makes it 125 and the XFX has a 5.99 shipping cost which makes it 126.


I'm really thinking it's the PSU mainly because when stuff like this happens, the freezing, it's a good indication the PSU is about to die and because of the fact now that I reset GPU back to stock and lowered the CPU multiplier from 45 to 40, it's working. (At least 4 hours)
I also read on some forums that the TR2 series from ThermalTake is a total piece of junk quality PSU that only really puts out 300-400w but is advertised as 850w.... which really makes me upset because I am pretty noob at this stuff and I went into Best Buy last September because my old PSU blew and I saw a Corsair which was maybe 5 bucks more and asked the guy working there which was better: the corsair or the ThermalTake, and he said the ThermalTake by a long shot... I REALLY don't ever want to go back to best buy again.. lol!


Any tips/suggestions/tips/thoughts would be nice.

EDIT: Sorry about my signature, that's my old comp - I'll try to update that! ~done

join the club. Seems like this is happening alot more! Many posts on freeze ups with SB. I fixed my issue, which was a power source connector issue to the cpu. Doubt its your psu. Might be, but doubt it with all the SB freeze ups lately. Cant hurt to have a solid Corsair or Seasonic psu though!

I've been pretty stable once I switched to 4.0 instead of 4.5, never got any blue screens - just freezes. This is why I am thinking it must be the PSU - I mean I survived 8 hours of Prim95, my temps are amazing, and I don't get bluescreens - but freezes.

I'm thinking the PSU prob can't put out as much power as it advertises... I read somewhere someone had exact problems with their ThermalTake as it was advertised 850w but only really put out 300-400. Low quality junk was the term I believe... let me see if I can pull that thread up.

EDIT: here they are:

and this one about 750w edition:

Quote:
According to our methodology, Thermaltake TR2 RX 750 W cannot deliver its labeled wattage. It burned after one minute delivering 750 W at a room temperature a little bit above 45º C. Thinking that we may have got a defective unit, we asked Thermaltake another sample, which burned exactly the same way. In both units the component that burned was one of the +12 V rectifiers.

Apparently it's not a good PSU.

It's junk. To be avoided. It's OEM'd by HEC, which for the most part don't create anything good. Its ripple is off the charts and out of spec and it can't deliver its rated wattage.

ALSO, Someone at hardforum was having issues with this PSU as well.

I think it's going back, something is making the system shut down with no warning now. Nothing else changed. I ordered a corsair hx850 a little while ago , $10 cheaper then this thermaltake. now just hope the rest of the system is ok.

yea you have the bad thermaltake psu's unlike mine, mine was recommended by johnnyguru and is actually a decent unit.
post #6 of 16
If u multiply the volts by the amps u gets wats or thats what im lead to beleve

So for exzample 12v rail 1 has 30amps
12*30=360wats on that rail

Add all the rails together for what u should have for 12v

Hope this helps

This doesn't work in most cases. If a 600W PSU has 4 (virtual) 12V rails of 20A each, you can't add them up because that would have you end up with 80A which is 960W, and more than what the PSU is rated for. Most of the time, the manufacturer will display the combined wattage on the label.

Example.

The PSU has 3 rails, 18A each. But the combined wattage is 504W (42A).

yeah that is true im guessing they have more amps to make it so u don't blow it up but pulling a few too many lol

in any case if your looking at PSU this post contains info on power supplys and tones of it

hope this helps with finding a new PSU

Well a good and bad update.

I ordered a new PSU (the corsair I linked earlier) and it will be hopefully coming in Friday, if not then Monday.

Bad news is... last night my GPU blew. I was changing some wallpaper and all of a sudden... the computer turned off. Automatically started up again and POP... fried smell... turned it off ASAP - but it was too late obviously. I luckily got an exchange for it from Frys and asked them if it was caused by my PSU, but they didn't know much. They told me "I'll be safe" so I decided to plug in the new one and here I am...

I reset the BIOS to default so no overclocking at all and I'm just hoping this will make it through until Friday/Monday without happening again... I'm thinking the high ripple and noise was too much for the system to handle? Basing it off ko888's post...

One question I have... how can I turn off the ability for the computer to automatically restart? I found a option in the BIOS that says "Restore after AC Power Loss" but it's already on "Turned off" and the other two settings is "Turned on" and "Last state"
Could there be any other possible settings?
