500 watts is enough for GTX770

 

you only need 600 watts for R9 290X

get a 550, or you could get a 750 if you are going to sli in furture

a good quality 500w 80+ power supply should be ok.

That's pretty crap advice.

 

A 770 will use around 230W and most systems with a 770 won't use even 500W, so why does Nvidia recommend a 600W power supply? The reason is that many people have crap/old power supplies that can't deliver their rated Wattage, and it's simpler and cheaper to recommend a higher Wattage power supply than to deal with a bunch of complaints and tech support issues.

 

If you want to give your location, budget, preferred retailer and any other preferences we can throw some suggestions your way.

 

Back to the crap advice part, there's more to power supplies than the brand. Corsair and Cooler Master are not the only makers of good power supplies, and not all of Corsair and CM's power supplies are great. This is especially true of Cooler Master, as they sell many low-end cheap and awful power supplies.

That's bullshit, the PSU is fine and 80+ Bronze is only effiency, says nothing about the quality of the capacitors and such.

 

Thermaltake makes good PSUs, not only CM or Corsair.

We've also got EVGA, XFX, Seasonic and what brand not who make quality PSU's.

Reasons to not use that power supply:

1. Only has 1 6pin connector. Good luck powering a 770 with that.

2. Two 12V rails, one with 14A and the other with 15A. I would not be comfortable running a 770 from this, even with the right connectors.

3. No 80Plus Rating stated.

4. That model number (TT-550NL2NL) is not the ThermalTake Lite Power 500W. It seems to be a very budget unit made to be sold in that case specifically.

5. Even if it was the Lite Power 500W, it would be crap. No PFC, no 80Plus (website gives ~70% efficiency), 36A on the single 12V rail (again, too low), group regulated. At least it has 2x 6+2pin PCIE connectors.

To be honest, that case is crap. For about the same you can get a Corsair 200R or Spec01/02/03. They don't come with power supplies however.
