Powerful enough PSU?

post #1 of 27
Thread Starter 
Hi, after having my PSU explode after overclocking a bit to far, I want to know the safe wattage of PSU I could have with my rig

Currently I have:

700w ACE PSU
ASUS P8 Z77-V
i5 3570k (4.5GHz, 1.35)
GTX 460 (I had the voltage at 1087mv when the PSU exploded, the GPU did not reach above 80 degrees C))

What psu would be able to cope with my graphics overclock, without exploding? smile.gif

Thanks

This is the type of outcome (lesson) easily avoidable by simply asking around a bit (here maybe, or similar places) before buying a PSU. smile.gif

What you have there is ~300W system at full load, that means that a solid 300W+ unit is all you need. The problem with your current PSU is that its rating is fake, and thus irrelevant, it is a cracker, it's made in an undisclosed location, by undisclosed under aged kidnap victims, or in the back of a Tuk Tuk... take your pick.
What is your budget for a new PSU and where would you be buying from? (I suspect you're in UK, so maybe scan/ebuyer?)

Thanks for the fast reply
I don't really understand how it can be fake; I bought it right from scan a few months ago (http://www.scan.co.uk/products/700w-ace-psuace700br-black-with-red-12cm-fan-atx-v23-psu)
Is there any way I can test it's true power without blowing it up again.

If I were to get a new psu, what would be the cheapest safe option to go for? And again if buying off scan, how could I tell if its rating is real?

Thanks

He means it's fake in that its actual wattage output is overstated by a large margin. PSU manufacturers and vendors can label the PSU whatever they want, there's nothing they have to do to prove that its maximum output is valid, and they'll just avoid the 80+ tests and put a fake sticker on it. We know that it is a bad product because we can find out what sort of internal platform it's based on, or if we can't find that, find where someone has taken it apart to look at the internals which will tell us everything we need to know about it. Occasionally review sites will also go out and buy these questionable models on their own to prove that they're junk.

The rating isn't fake but rather it is uncertified. 80 Plus certification guarantees that the power supply will have at least an 80% efficiency at 20%, 50% and 100% load. So the ACE power supply you have is not efficient which would mean that it is made from lower quality components. You will also find some brand names like corsair that have uncertified power supplies.

Look for a power supply that is 80 Plus certified. You can tell by looking at the technical specifications of the power supply on the scan site. The pictures will normally have an 80 Plus icon on the lower right hand corner.

Get one that either has

Any competent power supplies will be rated at DC output. If it isn't, then it is a trashy unit. In other words, efficiency is irrelevant in this discussion.

It means that the 700w is exaggerated and most likely it is only a 500w unit or less.

So would any of these PSU's work for what I need, and for any future upgrades (New GPU, second HDD, ect)
