Upgrading Thermaltake TR2 RX 750W to.....?

post #1 of 27
Thread Starter 
Hey Guys,

Ive been doing a lot of upgrading lately and look to upgrade to a new GPU and even do SLI/Crossfire. Figure along with those upgrade I need a new PSU to handle it, but since the psu has been the least of my worries I dont know anything about them.

I currently have a Thermaltake TR2 RX 750w. Overclocked 2600k and stock GTX 570 HD. I used a PSU Calc and figured with everything in my case, if I were to get another 570 HD I wouldnt have enough power to run everything. I believe I need 750-800w.

Now considering that fact that the 7xxx series gpu's just came out and kepler is right around the corner, I would want something that could support SLI/Crossfire for those cards..

Do my questions are:

How many watts do I need to support those types of high-end cards. Especially if I OC them (which I may, who knows)

What brand to buy? And further more, which rating? (gold,bronze,silver)

Thanks in advance for any help. I am sure you guys get this kinda thread all the time in this section. I hand out in Cpu and watercooling and you see the same threads over and over.. So i appreciate you puttng up with it

You'd probabally be fine with your current power supply for two 570s. If your really worried about overhead though I would look into a Seasonic PSU . They have a platinum and gold model in the 850 range. Both of them are basically as good as it gets as far as PSU quality.

Well according the the PSU calc. I used with the amount of fans in my rig, and the waterpump.. I wouldnt have enough for the second 570 let alone Overclocking them..

Now throw in the fact that I am interested in a 7xxx series GPU or a kepler (if they come out before june).. I think the power consumption would go up no? I think the new gpu's use more power if I am not mistaken..

I think corsair is where its at i was looking into those.. I dont know much about the other popular brands like the seasonic mentioned above..

Checked acouple other threads and I think the general idea is 850 will be enough for 7xxx gpu's.. any ideas on kepler cards?

Actually a proper 750W unit would be plenty for your current system.. however, the TR2 RX 750W is a poor HEC built unit that's anything but proper wink.gif

What's your budget?

I would say you'll be fine, but if it makes you feel better look for a higher quality PSU that can supply 750w.
If you're keeping your old one, I wouldn't be overclocking.

If you're going for a new one, check out the XFX 750w. It's a great PSU for the price it's at.

If you really want to future-proof the system, look for anything that meets your budget in the 850w+ range. I would recommend most products with silver/gold ratings from manufactures like Seasonic, XFX, Corsair, Antec, Cougar, NZXT, P&C, OCZ, or Silverstone.

Around $150? I mean a proper psu is an important component that I wasnt aware about when I first put the case together..
