I am buying a new graphics card and the one have been looking at was a Sapphire Radeon HD 7750. I am looking for a new power supply so I can use the card. Recommendations? I have been looking at them all day but I keep seeing that they break in a few months.

I would go with a 500 watt psu depending on other hardware being used in your rig...i do not know your configuration but go with a seasonic, corsair or coolermaster. typically any brand will do. usually you will want a plus bronze certified or higher standard. I usually go for gold certified. I would also recommend a modular psu for the convenience of cable management and it looks nicer but these will cost more. what's your budget look like?

You don't want CM; their budget offerings are universally bad (with the exception of the GX450). With no further upgrades planned, one of the 300W Seasonic 80+ bronze units will be easily enough.
What is your existing PSU? It may actually be sufficient. In the recent $400 Spirit of Mini-ITX build, Paul found that his system only pulled 119W from the wall: http://www.tomshardware.com/reviews/mini-itx-do-it-yourself-game-console,3531-17.html

The 7750 is about the strongest discrete graphics card that does not need an auxiliary 6 pin psu connector.
It is powered entirely by the pcie-X16 slot.

Unless your current psu is abysmally cheap, it should run the card.
I suggest you try it first. If there is insufficient power, you might see artifacts or other symptoms.

Get the modular version though; the non-modular ones use some inferior Samxon capacitors that do not like heat and are known for early failure. The modular ones (although they're all made by CWT) use all-Japanese capacitors.
Another inexpensive option is the 380W Antec Earthwatts, also sufficient for any graphics card with a single 6-pin PCIe power cable.
