Please help me find for 50 bucks that can power

Made by the best = SEASONIC.

Will easily power a 770 and allow overclocking.

With 44 amps on the 12v rail , will meet your needs.

Please do not buy a cheap PSU. It will save you lots of headaches to just buy a nice PSU from Corsair that is 80$ now than it will be to replace $1200 in damage caused by a cheap PSU surging.

Dark Lord of Tech · Feb 11, 2014

i know xfx is good i was replying to the other guy

Dark Lord of Tech · Feb 11, 2014

The CX500 is a poor power supply with cheap capacitors , get the XFX linked above..

sweenytodd · Feb 11, 2014

With that budget, 550W would be the minimum power you need with that system. This XFX is made by Seasonic http://us.ncix.com/products/?usaffiliateid=1000031504&sku=59615&vpn=P1550SXXB9&manufacture=XFX&promoid=1363

Some people buy refurbished Corsair power supplies on NCIX for cheap and they have good experiences with it.

marc79 · Feb 11, 2014

CX500 is budget mediocre psu, the XFX is better and has a 5 year warranty as opposed to 3 years.

Dark Lord of Tech · Feb 11, 2014

Already posted the XFX 500W above.

Chitownkid · Feb 11, 2014

blackbird i really apriciate it but i have a strict 50 dollar and no mail and rebate limit sorry but thanks

Chitownkid · Feb 11, 2014

Dark Lord of Tech · Feb 11, 2014

Going to cheap puts your other components at risk.

Thanks for posting in the forums.

marc79 :

well lets just say you had to pick between the cx or an evga same wattage what route would you go

You need a power supply with at least 443W on the combined +12V rails.

Without over clocking, the cheapest power supply you could get away with is the Corsair CX 500.
You will be loading this unit at about 75% of rated power when playing games.
This means efficiency will be down to just over 80% and it may be a little noisy.
The cheaper capacitors used in these units will also have a reduced life span compared to better units.
The Corsair CX 600 is of similar quality, but the higher rating will make it quieter and last longer.
You would have to choose the 600W unit to safely over clock.

The XFX Pro550 is a big step up in quality from the above units.
Depending on the web site you may find this as "xfx pro 550" or "xfx core editiion pro550".
The 550W rating is much safer than choosing a 500W supply.

You can also have a look at this list:
http://www.eggxpert.com/forums/thread/323050.aspx

Anything from tier 1, 2 or 3 should be OK.
Choose a unit at least 550W preferably.

Dark Lord of Tech · Feb 11, 2014

Both are about the same quality.

SO http://pcpartpicker.com/part/ocz-power-supply-ocz500mxsp this is fine, people said only prob is warrenty

Chitownkid :

EVGA and Corsair both sell good models and bad models.
Spending over $700 on a video card, cpu, motherboard and RAM then using a $50 power supply is just stupid.
The XFX supply recommended above (by pretty much everyone) is great for $70.
Here is a Seasonic branded unit for $74.99 as well, which is 80 plus gold rated:

Just to add some more variety.... http://www.newegg.com/Product/Product.aspx?Item=N82E16817139028

VincentP · Feb 11, 2014

Quality is OK, but this unit is rated at 34A (408W) on the +12V rail.
This isn't enough to run this system reliably.
The EVGA 600B would be OK, but this is no cheaper than the XFX Pro 550.

I mentioned the Corsair CX 600 above.
It would do the job, quality is OK for a budget supply.
