Hi, I am having troubles with every PSU I've bought, the first one was a Generic 500W (not real) PSU that lasted for a year, when Iw as playing Crysis it burned...

Then I bought another one, it was a 600W Generic (not real) PSU. I was surfing the internet when the computer went off by itself and then I figured out that the PSU wasnt burned but woulnt give power to the motherboard.. So I changed for antoher one.

That next one was the same as the last one, a 600W generic. It lasted 2 months, While I was playing COD 4 yesterday with settings on max, the psu started to show sparkles of electricity and it went off, then it smelled like burned..

I had problems with this last psu before it burned because everytime I was playing a game like Crysis, Assassins Creed, or COD 4 MY PSU SMELLED LIKE BURNT , this didnt happened while surfing the web, it just happens when Im gaming.

Now I dont know what to do, I dont know if the problems Im having are related to the quality of the PSU, maybe I should buy a good one like a Thermaltake 750W toughpower. But I'm afraid I could burn that one too...

Can you guys help me decide here?? I really need help, I dont want to be burning more PSU's....

My system Specs:
AMD Athlon 64 X2 4200+
MSI K9N Neo Motherboard
2x 1Gb DDR2 Kingston 5200 at 667Mhz
EVGA Nvidia Geforce 8800GTS 320Mb
--------------------------------------------
Case:
Thermaltake MATRIX VX. 2 Thermaltake Fans/Front and Rear, Dust Suction on Front.

A Corsair VX550W should handle your system no problem.

A Corsair TX750 or your toughpower 750 would be very nice if you ever think of SLI/Upgrading machine. Stay away from VALUE PSUs !!!!

Follow my rule, if you ever had a beef heavier than your PSU, your PSU sucks !!!

thank you!

Then my problem is the cheap non-brand PSU's I'm buying. Im not planning on building a SLI system in any future, so a 550W-600W Real Power good brand PSU handle all my games??

I just searched brands like EnergeMax, Thermaltake, Corsair, BFG Tech, CoolerMaster.

then spend the money on something that lasts and don't be cheap being cheap can cost more in the long run if you constantly replace broken hardware

That will help to understand why NOT to buy cheap generic PSU's.
Good 450W like Corsair VX450 will do for You. But to leave a bit of headroom I would recommend 500W or more good quality PSU like radnor's recommended VX550

Great video. That's what my X's Brand PSU did, it blowed like that! Thank you.

I thought I needed something like 750W but reading the Corsair site I've realized that a 550W at 89$ would be great.! I've already spent like 90$ on 3 X's brand PSU....

One more question, what is it with this Corsair PSU's and their its single 12V Rail.. Isn't it better a PSU with more 12 V rails?

I prefer a huge 12v rail. The PSU distributes power.

Or do you prefer a 750W PSu, that only gives 240W in the 12v rail ? (PCI-E)
I prefer the whole 720W on the 12v rail if necessary. With a 750 PSU.

Imagine if you card uses 250 Watts in full load. And your PSU only gives 240 Watts. Bugger isnt it.

dual, triple, quad rails was just a marketing trick. Most of them still had one rail split in several current flows with a current limiter on each flow. And many did not have even that. What You want is a one huge rail. for example if You have two rails of 17A and cpu use 8A on one rail and video card 15A + other peripherials (5A) on second rail hten You run out off puff on second rail. If however You have one railwith the same combined current of 34A You are fine - 8+15+5=28. It is better to look for single rail. But don't worry too much as I said most that are advertised as multi rail actually are single rail anyway. Just a marketing trick to make people buy them.

i had the BFG Tech 550W PSU(mine was the GS series) but i upgraded my PC so i had to get a Ultra LSP 750 watt. the BFG is a nice unit. 135mm fan that sucked air from inside your box and out the back of it. really nice finish on it. sorta chrome-ish or a gun metal chrome finish.

you prolly don't want to hear what the finish is like. i was powering a P4 3.0 OC'd to 3.4; 2 gigs ram OC'd; 3 - 160GB SATA HD's and a 7800GS agp gfx card oh and 1 intake and 2 exhaust fans. the card alone req. 400 watts and i got a 15% deal on the psu.

i don't too much about output of the power as i dont know what a 12 volt rail is(i know what a 12 volt battery is :p ) but for the money and a Life-Time warranty you cant go wrong. But if your willing to spend the extra $$ to get the other unit - get it.

I actually almost bought a Corsair psu(750 watts) similar to the one u linked but i got the Ultra instead. it was like $60 cheaper than the Corsair and the Ultra has a 135mm fan on it(which i like), like the BFG and sleeved cables. the Corsair didnt.

BFG - $85 - Best Buy
Ultra - $106.99 - CompUSA in store
Corsair - $160.50 - CompUSA in store

really the only reason i didn't get the Corsair is because I only brought $160 cash, so i had to get the Ultra and it was the last one left. so i got lucky :)

I think the Corsair 550 was the best choice for your system of all those mentioned.

Remember the PSU powers all your expensive hardware, don't skimp on it.

its a BFG 550 watt and a Corsair 750 watt not a Corsair 550 watt.

Guys I was searching on Amazon, it is the only online store I can buy in USA and ship to my country ( I'm not from USA).

I think the best price for my Gaming Rig is this Corsair 650W TX Power Supply.
Everybody tells me that i should get a 550W Corsair. But I want to know if this one is better for my games.

http://www.amazon.com/Corsair-650W-Power-Supply-CMPSU-6...
Thats the link.

I cant buy the 750W too expensive dont have enough credit on my credit card.. I need a price below 100$ for the duty charges..
July 24, 2008 8:35:06 PM

what are your specs? cant really help you unless we know what you have. :)

The Corsair 650W will do fine also.

You'll be happy with a 400w psu on that little rig.
The power supply is the single most important part in stable running of your system. Why skimp on it?

You'll pay double the price of a high end psu after a few months with generic rubbish anyway.

Corsair makes pretty PSUs, so do Fortron source and "be quiet!"

Thanks, my Corsair 650 is on the way
