Need a good PSU for GTX 660 Ti. Help?

post #1 of 6
Thread Starter 
Hi,

I'm looking to replace my dying GTX 660 Ti with a GTX 770: http://www.overclockers.co.uk/showproduct.php?prodid=GX-202-MS
However, I am concerned that my current PSU (Antec 520w High Current Gamer) is not sufficient, so I will need a new one.

Can anyone recommend a good PSU for my rig?

My rig is:

(1 Terabyte Hard Disk,
Windows 7 Home Premium 64 Bit,
Nvidia GeForce 2GB GTX660Ti,
Intel i5 3570k,
ASRock Z77 Pro3 Motherboard,
8GB DDR3 1333Mhz Memory,
Antec 520w High Current Gamer Power Supply)


Thanks.

Your current PSU is a quality one and is more than enough for your setup including the 770.
Your whole system with the GTX770 will consume less than 350w under full load.

Here's how to put your rig in your sig:

Are you certain? Nvidia recommends a 600w power supply for the GTX 770.

GPU manufacturers vastly overstate the recommended minimum to cover themselves for people that buy really crappy powersupplies.
Your rig wouldn't use more than 350W at full load.

This iChill HerculeZ X3 Ultra clocked at 1150MHz consumes around 200w under 100% load.

The 600w rating by Nvidia is for crappy Peak-Power PSUs (which there are a lot more of them out there than good units), but yours is a quality unit that can deliver +500w all the time.

You dont need a new PSU as said Nvidia are talking about units that can do up to 600 watts or peak rated units which in other words are crappy PSU´s

Yours is not so you dont need a new PSU
