Want to upgrade but unsure if my PSU can handle it

Hi, I'm new to your site but registered to ask a question about upgrading my video card. Basically, I am thinking about upgrading my card due to the slew of games coming out this fall and am a tech noob. I want to know if my current PSU can handle an upgrade and, if so, what is the best card I can upgrade to with my current setup. I've been to power calculators on the net but they seem very thorough and every time I do use them they estimate a power consumption that is higher than the one I actually have. Here's a list of my specs:

-675 Watts - Thermaltake Toughpower XT TPX-675M 80 Plus
-Azza Solano 1000 Full-Tower Advance Cooling Case w/ 230mm Fan + Extra 3 120mm Fans
-Samsung SH-B123L 12X BLU-RAY Player & DVDRW Combo
-AMD Phenom™II X6 1090T
-CoolerMaster V6 GT CPU Cooler
-INTERNAL 12in1 Flash Media Reader/Writer
-1TB SATA-III 6.0Gb/s 64MB Cache 7200RPM HDD
-30 GB Kingston 2.5 inch SATA Gaming MLC SSD
-4GB (2GBx2) DDR3/1600MHz
-GigaByte GA-870A-UD3
-Killer 2100 NIC
-Aerocool Touch 2000 Dual Bay Touch Screen Fan Control
-NVIDIA GeForce GTX 460 SE 1GB 16X PCIe Video Card
-Logitech G35 headset
-Logitech G9x mouse
-Logitech G15 Keyboard

Thank you for any help.

  1. I can't find any reviews of that PSU so it's difficult to determine the quality. The specs claim 56 amps. on the 12v rail so I'd suggest buying a GPU that uses 300W or less under max load. This would give you some safety margin if the PSU is marginal in quality and power output.

    It looks like you could move up to a GTX 570 or HD 5970.


  2. thermaltake is a good product. you're good to go for a gpu upgrade.
  3. I would say go ahead and get another GTX460 for SLI.Your PSU can support it.

    I know for sure that with the new 9xx series mobo's you can do SLI but i'm not sure if you can on the 8xx series.You should look more into that
  4. he really wouldn't want to do that 460 "SE" sli.

    i'd say it more economical to invest on a 560ti/6950 or better.
  5. I didn't see it was a SE.Good call.

    I also agree the GTX560ti or 6950 is a good choice.
  6. thanks for the replies; definitely helped a lot. I'm assuming the 560ti and the 6950 are pretty similar, gaming wise?
  7. Yeah GTX 560 Ti is your best bet.
  8. Yes they are very similar.
