Windows 7: bought gtx 680 wanna know if my psu is enough. (quick reply please)

i have a 600w coonix it is a dual rail i believe and only pulls 36 amps together and the minimum the gtx 680 says is 38 amps but it also said it was tested with an i7 3.2ghz processor and that also mean a high end board with other high end part. and i only have a fx- 4 core black edition. my mobo is a m5a97. 16 gb of ddr3 ram and one dvd-rw and one 7,200 HDD. so not much of a power drawer.

If you're looking for someone to bless the use of an expensive graphics card with a marginal power supply, you've probably come to the wrong place.

If the PSU fails due to being run close to its rated specs for too long, it can take most of the rest of the system with it.

some people dont realise but the PSU is the REAL heart of a system, CPU is just the brain

save up for a better PSU or u might have to save up for a whole new system

Stick with Seasonic, Corsair, Antec for your power supplies. There are a few other good ones out there, but these are probably the top 3.


From what I can see, the Coonix 600W has 2 rails at 18A each. For a total of 36A

To put things in perspective, a Seasonic 460W will produce 38A on a single rail. Many of the Corsair and Antecs can also match or exceed this PSU at 450-500W range.
And thats not even considering effeciency.

The 620W BobKn linked has 48A on a single rail, vs yours that 36A spread over 2.


I would look into putting a good quaility PSU in.
Huge fan of Seasonic myself, but have had both Corsairs and Antecs and they all havbe been excellent. (Most are made by Seasonic anyway) The one linked for example would be a nice upgrade.


--Also, if Im not mistaken, that AMD CPU will pull more power than a i3. Someone please correct me if wrong.
And, FYI, the number on the GPUs box that specifies min. wattage and amps is a generic figure and is intended for the entire system. Not just the GPU.

Coonix is not a very reliable brand. a PSU with more than one 12v rail is not much good, just make them cheaper to make.
As was stated, a good PSU id the heart of a good system and I would recommend you look into a minimum of 750W. 850W would be better.

I see you have has many BSODs, could be the bad PSU you have.

You should get a new PSU.. Get at least Cooler Master GX series or Silent Pro series with at least 750W or get Corsair HX 850W Modular if you can.

I agree Quality Psu is a must Vs cost you will end up spending more in the longrun if you don't listen to this good advice given to you

You can get a great 80plus for 100.00 or less depends on what you are going for Brand wise

If you plan on going Sli in the future go Big

If this is all you need then get something 700w 80 plus modular or anything with single rails going higher then 34

There is even this one not 80 plus but one rail is 52amp Newegg.com - COOLER MASTER eXtreme Power Plus RS700-PCAAE3-US 700W ATX 12V v2.3 Active PFC Power Supply

It get's the job done no doubt but I have it in another system running less specs which is great and not overkill especially if i add a more powerfull card

The GTX680 is a lot less power hungry compared to past Nvidia GPUs. Plus, most people buy more wattage than they really need. I could definitely see an excellent 650W PSU powering a GTX680 SLI config (long-term, even after some degradation). This is why a good PSU is often recommended over higher-powered PSUs from questionable brands/manufactuters (along with other reasons).

sorry guys i havent been on but ive been doing research and i like this one. Rosewill.com - Computer Case, Power Supply, Computer Accessories, Networking, Peripherals. Price, Quality, and Services.

also BSOD were because of bad mobo or ram had it fixed. havent had one since. my other choice would be a corsair HX 750 but thats another $50 so im not sure
