Faulty Power supply?

post #1 of 20
Thread Starter 
So I bought this power supply back in august of last year, and since then Ive added a full water cooling setup (2 rads, 1 pump 1 res, cpu block) also have 11 fans, 10 on the rads, and an exhaust fan. Running the current gpu overclocked, cpu overclocked, I have 2 hard drives and an ssd drive, cd drive, and a light kit.

Yesterday my fans on one of the rads stopped working...Also I was playing BF3 and I was getting half the amount of frames. I thought it was drivers, so I uninstalled, then did driver sweeper, reinstalled new drivers. Even went to the extreme of reinstalling windows. Still. Also the lights are dim on the light kit.

Is this a sign of power supply failure?
If so is this a good replacement?

it is a very good replacement. i think you might have been at your threshhold witht he other PSU but you will have some overhead with that one. go for it.

That power supply will run 4x 6950s, it's a very good unit but a poor solution for your setup, you need something a lot smaller.. but first you need to make sure it is a PSU issue, you need to check the PSU voltages using a multimeter.

What specific Cooler Master PSU do you have?

Ive got this one.

Why do you say the one Im buying is a poor solution to my setup and why would I want something a lot smaller????

Because your system draws about 400W at full load and idles below 100W, and you don't wanna' keep your PSU below 20% load... ideally you want to idle at around 20% load and stay at around 80% when your system is under full load.

Look for something around 500/550W if you want to stick to a single card setup or 650/700W in you intend to crossfire.

UCP series was made by AcBel and they were very solid units, they also had 5 year warranty so you should call/mail Cooler Master and initiate an RMA

400W?? I think not. I think when I ran the psu calculator from overclock.net I was getting about 650-680 usage, using the psu calculator on newegg I was getting 780 usage.
I will be adding either a 6970 or 6990 to the mix, or switching out the 6950 for 2 570's.

Why are the lights going dim, fans stop spinning, (all 6 at the same time on the 360mm rad) and gpu usage shows 100% but Im only getting half the frames I normally get? this is with 3 different drivers now.

EDIT: I dont think I can RMA a sleeved psu....

You think wrong, I couldn't care less about what a newegg calculator suggests.. what power do you think your VGA and CPU are using?

6970 ~230W at full load(in anything except Furmark)
Nehalem @ 1.4v ~150W at full load
everything else <70W

ps. just saw you're running the card unlocked.

The lights are going dim probably because they're fed lower voltages than normal, that's why I suggested you get a multimeter and check them to know for sure..

ok thanks.

EDIT: At load I can be pulling as much as 400 watts on my cpu according to these guys.

Since you can't RMA the unit, I suggest you get either a Kingwin Lazer Gold 850 or a Rosewill Lightning 800, they are internally similar(they use the same platform) and are made by the same OEM as the one you linked in the OP.. but unlike your option, which is a solid mainstream unit, these units are high ends with better regulation, better ripple suppression, better efficiency and better components, they're also quieter and they run cooler.

If you look in the psu forum there should be a sticky there with phaedrus' psu calc. See what it says. I would then account for 10-20% overage. That was why I said the 1000w would be good. With all your components( similar to mine) I am getting 700w usage
