My graphics card recently rested in pepperonis and I wanted a replacement. My GPU that died was the Radeon 7770, running on a 400W power supply. Would the GTX 760 be working with my power supply?

More about : 400w psu gold sufficient gtx 760

Depends on the exact model, but I wouldn't recommend it.

for gtx760 at least a 500w with 2x6pin pcie power cables capable psu will be needed. a 400w psu cannot run such gpu.

Depending on the model, and your other specs, it might work. What are your other specs?

You can run an i7 4770K and a GTX 780 Ti off an RM450

Assuming that would even work, it wouldn't take long for the RM450 to blow up.

The RM uses the same capacitors as the CX series and therefore has heat issues and a relatively high failure rate; I wouldn't recommend it to anyone.

But yes, it would run the GTX 760.

And FYI, some GTX 760s only need a single 8-pin: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

to sum up, i recommend these two. evga 500b if you have a limited budget, or best option would be the xfx 550w

yes depending model, factory overclocked may require more. the point is that psu of 400w and below are best suited to power gpu wihich draw power only from the pcie socket, such as gtx750ti

Edit: Slight mistake, it was a 4670K.


at idle room temps you can have it running.the wormer the enviroment the less the ability of the psu to output power. also he did stress test only the gpu. he didnt stress test both cpu and gpu. for several hours of gaming that wouldnt been possible and running the psu maxed out all the time would shorten its life span. no one recommends psu to be running maxed out or obove their rated power, even if they could. psu produce their best efficiancy while running at 50-60%. that is the way they are meant be be operated for long lasting operation and in order to be on the safe side.what he did prove is that you need a higher wattage psu

A 760 will pull a lot less power than a 780 Ti though, so there will be more headroom for his PSU, although we need the model as well as his other specs.

i said that rm 450 is enough for 760. i just dont recommend it. for the money rm costs you can get a better one, or still get a decent one with a lot less money. what would be a best fit will be defined by rest of the hardware

as previously mentioned for (almost) any set up these would fit best

Power Supply: EVGA 500W 80+ Bronze Certified ATX Power Supply ($34.99 @ NCIX US)
Total: $34.99
(Prices include shipping, taxes, and discounts when available.)

the seasonic made xfx would be best at such price and overclock as it gets!

And I'm saying that this 400w PSU might be suitable if from a good brand. Linus has used a basic 450w from Seasonic in a build with a 780 and it worked fine.

im sure he did! everybody wants their psu to last at least for 5 years, not 5 months!
