Will this PSU run a GTX 760?

Will this PSU run a GTX 760?
http://www.techpowerup.com/reviews/MSI/G...ng/25.html

indicates power in the peak gaming at 152 watts,
furmark stress test max load is 210 watts.

210W/12V = 17.5 Amps // worst case
152W/12v = 12.6 Amps // peak gaming

This is the label on a stock PSU from a dell xps 8700, and I'm wondering if it will run the card above.

18A
16A
8A


CPU is a core i7 4770, no overclocking.
8GB memory,
Hard Disk,
will have an SSD someday
DVDR, bluetooth, wifi

The PSU has 12V connectors to run a Dell version of a GTX 660, which look like they will fit the 760.

do you-all think it will work?

RE: Will this PSU run a GTX 760?
It looks like you could skate by; although, most PC manufactures aren't known for bundling quality PSUs in their case. Even if it meets the requirements on paper. The 760 doesn't use a great deal more power than a 660 though, so I wouldn't worry about it too much. The 760 has both a 6-pin and a 8-pin connector, but it comes with adapters, so you should be good there, as long as there's a nearby molex connection.

Are you saying it already has a GTX 660 installed? If so, I guess the real question would be this: is it worth it to upgrade a GTX 660 to a 760? It depends on the game and resolution, but it seems like you'd be spending $250 for a 10-15% performance gain. You may want to just grab the SSD or something else first, and maybe save up for the new PC. Of course if it doesn't have a GPU at all, ignore this...

Sorry for not clarifying. This system has a GT 635.

I am looking at some options and alternatives.

To clarify the rest of the puzzle, My son has a nearly identical system but with a MSI GTX 760 and a Seasonic X-650. I'm considering upgrading my system, but considering future options.

If I get a MSI GTX 760, matching the one he already has, in the future these could be paired in SLI and from what I read, will have pretty good performance. It would be in a completely new system built from the ground up so this may never happen, but having two matched GPUs could be a starting point.

Another option is to get a better single GPU for his system in a year or so after the new models come out, and "hand-me-down" the GTX-760 to this system.

A question I've not asked is at what point will a non-overclocked core i7 and DDR3 1600 be a bottleneck? Will a GPU in the GTX 780 range bottleneck this CPU and memory at 1920x1080 resolution. Typical games are AC4, Skyrim V and likely future games in this general direction.

tnx in advance,

ps: SSDs are planned. just need to find a day to re-install everything.

RE: Will this PSU run a GTX 760?
Nah, your CPU and RAM wouldn't be a noticeable bottleneck, unless you were going with a 3 card setup, or something crazy like that. Of course, that would be a total waste for a 1080p display!

I think tossing a 760 in there for now is a solid move. You'll just want to scale back some settings, especially Anti-Aliasing (AA) in newer, more demanding games. (http://www.anandtech.com/bench/product/1038)

Another consideration may be heat. I don't have much experience with those Dell towers, but make sure there's some air moving heat from the card out of the case. If the GPU has a shrouds that directs all heat out the back of the case, you probably don't have to worry about it. If there's room, you could even stick a 120mm fan inside the case, facing the rear and blowing over the GPU.

Oh...make sure you measure the case and the card dimensions, to ensure it will fit. Smile

Thanks. sorry I wasn't clear, I have two almost identical dell xps8700s. One is my Son's and I already added upgraded the GPU to a GTX 760 along with a nice PSU. It is a snug fit, but works great. heat is manageable.

I'm looking at options for mine, and one option is for me to take the 760 and get a better GPU for his. Or, get another 760 knowing two in SLI might be a nice alternative for a new system.

RE: Will this PSU run a GTX 760?
if you follow the label on the psu it will handle it. your gonna be pushing 300w on the 12v rail with all other 12v components added together. BUT, those cheap chinese power supplies most of the time can only handle 50-75% of rated wattage before they start throwing ripple current on the 12v line. put it simply, if it were me id invest 60-70 bucks on a descent psu if i were gonna add a mainstream gpu.

good luck

Thank you. This was the piece of the puzzle I was missing.
