Helloooo! I wanted to upgrade my alienware x51 to a gtx 760. I have a i7 -3770 dou core processor. And will be purchasing a 330watt to upgrade the current psu I already have. All I want to know is WILL and how it will perform on my processor combined w/ a 330 watt. Also is there anyway to upgrade the psu beyond a 330w? I know there are ALOT of restrictions on upgrading the x51. Thanks

Sadly, a 330W would not be enough to supply a 760 and the rest of your components. You will need at least 500W or 550W for extra headroom.

Maybe it could but I was trying to say was there was not enough headroom. ;)

Lots of people without Alienware x51 always say ohh your computer will go on fire. ooh you gpu will break, well I typed this for someone else hope this helps.

Guess What I two are in the same Situation and You know what Do it! I'm also pretty much did it I had a MSI 2GB GDDR5 and I'm upgrading to a EVGA 04G-P4-2768-KR G-SYNC Support GeForce GTX 760 4GB 256-Bit GDDR5 PCI Express 3.0 SLI Support SC 4GB w/ EVGA ACX Cooler Video Card

My old graphics card overheated because of a cable that got in the way. But lots of people with x51's are using the same exact graphics card as the one i have listed above. I'm a bit skeptical of when it hits its max power Supply but really using Google chrome, Steam and Photoshop i really only use 15 - 25Watts AT MOST. So the power supply we have Brother it puts a 19V Output so we pass the Voltage but the Minimum 500W PSU is recommended it will work but may i offer you to use the EVGA PercisionX 15 to regulate the Power use to go down!

Now the ACX coolers is going to make your GPU sound like a a wind Tunnel becuase of the Compact space in the x51. So at times it may be a bit on the louderder side but at least you know that its cooling and not risking damages.

Hope you have my word in this too!

Also I talked with staff of EVGA the Specs matched up with my MSI 2GB 760 so it will fit the case. Also the MSI had the same power consumption as like in the EVGA Graphics Card.

The max Power consumption is always going to be 170W to 220W. For this graphics card EVGA 760 with 4GB has a 170W which my old msi was the same it worked so I don't See why not it wont work for the EVGA.

85w for cpu, 50w for drives/fans/mobo, 75w for pcie, 150w for gpu. That's power potential for a single gpu w/i7 3770. Total = 360w. Granted you will not use all of the potential. You will kill a 330w psu not to mention probably damage the gpu. At 12v, a 170w card will pull 14.1Amps from the 12v rail. The psus i looked up carried 12v outputs ranging from 17A to 19A @330w. That leaves 3-5A for the rest of the system. No where near enough. Total wattage is based on a manufacturers idea of whatever they decide the formulae to be. Not that important. Total continuous power output on the 12v rail at 35-45° is most important.

It'll work, to surf the interweb, read some email, mebe a game of ms-hearts... But if you push that psu to its limits, somethings gonna give. Its too small. 520w-550 is whats needed for a 760, a psu with 40Amps output, not 20!

I'm not matching Max wattages here.

I included EVERTHING plus the mother board i came to a whopping 328.
You way over shot the fan wattage 50W way to much maybe if the fans had leds not mine. i have two small fans one for chassis and one for CPU fan. now the GPU fan is built in with maxmium consumption of 170w i put that into the Wattage as well. I under stand your point with pushing the PSU but really my MSI graphics card too also said you needed a 500W PSU well im not using well nothing over heats computer is silent as can be fans run smoothly using 3 Ultra wide monitors, yet nothing.

Used this site: http://www.buildcomputers.net/power-consumption-of-pc-c...

Alienware x51 has a output max i think 22V on its PSU if i read right. I don't know you need to have a alienware x51 to have a word in this. Oh well is the PSU goes. So will my computer and ill just buy another. If your a PC gamer it takes expenses and learning new things.

Also i have a 760 in their the only time is see trouble with it is when i overclock it. it shuts my monitors down. thats it. I'm sure this will work but like you said i'll push the PSU but really i'm really sick of this computer not being upgrade at all because of this PSU, but really for some reason the hardware i put in always works and never have problems intill i start messing with hardwares preformance.

Now i or he could use PercisionX 15 to control the power consumption so that could reduce crashing and risks!

Ok, also using Minecraft(512x512 Texture Pack), Chrome with YouTube, Photoshop the MAX power consumption all around is using a Estimated 23.21 and its peak was about 30.72W and a low of 12.31W. So really to be honest i could positively hit 330W but if i watch my consumption and motorize it really i should be fine and keep in mine im using multiple programs at the same time.

It's a chance i'm willing to take!

It's not about the wattage. Its all about the amperage. If a psu has a 20amp output on 12v rail, thats only 240 watts. The total of 330 is a made up number. The manufacturer uses a made up formula of mixing the 3.3v (usually 25-30amps, @90w) and the 5v (again 25-30amps, @150w) with the 12v output. You keep thinking 330 watts. In reality your gpu is pulling 170w from that 240w rail. Modern pc's use very little 3.3v and 5v, but the psu must still conform to atx standards.

Most fans pull @3-6w, average system having 3 fans, then add hdd, optical, motherboard and 50w is not hard to reach.

Every system is different, granted, but generally you really want to keep max psu @80% or do the wattage calculator and then multiply the answer by 1.5. Thats the size psu minimum you'll need to maintain a healthy pc. Anything less and you run the chance of undervoltage or undercurrent conditions, which will lead to early component failure.
