Need to know reason behind the PSU blow out

Archeritsme · Jul 8, 2014

Hi,

Yesterday i have installed Asus GTX 750 Ti on my motherboard. This Graphic card is really good it does not required any 4-6-8pins power supply, It take the power from PCIe.
My system specification:
Intel G35 Motherboard
6GB DDR2 Ram
Core 2 Quad Q6600 2.4Ghz Processor
Asus GTX 750 Ti (with a minimum 12V current rating of 20A)
Odyssey 450Watt Computer Power Supply SMPS
http://www.ebay.in/itm/450Watt-Computer-Power-Supply-SMPS-SATA-Connectors-2-Yrs-Warranty-/121178730283?pt=IN_Computer_Components&hash=item1c36d0af2b

After installation, Within 2 minute of game play (watch dog) i heard short circuit kind of noise and then the system turns off. It smells like burning, immediately i switched off the power and removed the graphic card and checked for all component of system for any damage or burn.
Luckily found no damage on any component except the PSU.

Just i want to know.
Is this happens because of cheap PSU.
Is this happens because of PCIe 3.0 X16 Graphic card on PCIe 1.0 slot.
or The graphic card is faulty.
Or my System specification are not meeting with the Graphic card requirement.

This video shows how the fifa 09 works on my PC after installing Asus GTX 750 Ti. This game works fine on Zotac 9400GT.
Is this a game problem or Graphic Card problem.
Please let me know, if this is a graphic card problem.

its a generic powersupply thats ur reason prob fried the rest of ur components

This is purely the problem of a wost possible quality PSU, with horrible capacitors and usually able to deliver only the half of their rated power. Nothing else. You are lucky if nothing else got burned. Get yourself a nice XFX 550w and call it a day.

Is this happens because of cheap PSU.

Yes.

Cheap power supplies = this http://www.youtube.com/watch?v=Ezk9OA7aKOE

This video should be playing on big screen in every single computer store. Always fun to watch, not so fun to the other components, though...

Dark Lord of Tech · Jul 8, 2014

I don't know why so many people build these real nice computers then choose a real cheap supply. :??:

iceclock · Jul 8, 2014

i beleive its a lack of education of the matter

Archeritsme :

From TOMS HW most recent build a PC tutorial:

Although it doesn't get its fair share of recognition, the power supply is the single most critical component for system stability and longevity. We've seen cheap models literally go up in flames, taking out several key pieces of hardware in the process

USAFRet · Jul 8, 2014

Because its a little black box that no one ever sees, and doesn't affect their uber frame rates.

Except when it explodes.

$400.00 cards and a $50.00 supply?

herrwizo · Jul 8, 2014

Yeah. One thing is universal, though, once people get burned, they never buy cheap psu again. This is also an education of sort, too bad its often an expensive one. Cheepskating is never worth it with psus.

iceclock · Jul 8, 2014

i never used generic well only once and never again

USAFRet · Jul 8, 2014

They get the cheap supply specifically so they can get the $400 card.
Or "I just spent $1500 on parts and don't have enough left over for Windows"

From a thread started a few minutes ago:
"I'm building an expensive gaming rig soon. The thing is, to save money, I'm going to exclude my HDD and Windows at the time of the intial build and buy them later."

Unreal.

Everyone is right. It took me a few tries to realize this. My roomates older computer had a Bestek (absolutely aweful) that came with it and it lasted a couple years. I unknowingly replaced it with another new identical one and it maybe lasted a year. So I replaced it with a higher powered one that was 35$ thinking by the fancy name it was better than the 20$ Bestek. This one in 4 months ... well, the machine was off and I was in line of sight of the machine and had the side off of it, and all of a sudden I see a FireWork show. Loud crackling and sparks flying out the side that was like 15 BlackCats going off. LUCKILY this did not damage the MB, processor, or memory or catch the house on fire. Bought another one for 65$ that is still going after two years and has had great reviews. I would do some research on the top rated midpriced, or higher priced if you can afford it. <:0)

Because this game works fine on Zotac 9400GT and Not on Asus GTX 750 Ti.

Which PSU best suite to Asus GTX 750 Ti:
(500-550Watt)
Cooler Master Thunder 500W 500 Watts PSU
Corsair VS550 550 Watt PSU
Corsair SMPS CX500 500 Watts PSU

(450W)
Cooler Master Thunder 450W 450 Watts PSU
Corsair VS450 450 Watt PSU

Or any PSU whatever you guys suggest.
