Is 500W PSU good enough for a GTX 1070?

[chris10123]

Hi all

I'm looking into buying a GTX 1070.

My current system is as follows:
i5 4690k (overclocked as far as the stock cooler allows)
16GB 1600MHz RAM
GTX 670
Corsair Builder 500W Bronze

The full model name (from Amazon) of the PSU is:
Corsair CP-9020059-UK Builder Series CXM500 ATX/EPS Semi-Modular 80 PLUS Bronze Power Supply Unit, 500 W

Will I be alright if I replace the 670 with a 1070, or am I cutting it a bit thin power-wise? Since the 1070 is already a fairly hefty investment, I don't want to have to replace the PSU as well (it's only 2 years old), but I have the funds if it's necessary.

If you do recommend that I upgrade the PSU, could you please suggest one if you have one in mind?

Thanks in advance!

Sure the 1070 requirement is 450~500W so your with in the requirement. Plus the requirement is a bit overstated.

The CX500M can run a 1070 , but not the greatest in terms of quality , the CX550M is one of the improved platform models by released CWT.

A GeForce GTX 1070 needs 30 amps on the 12v+rail and at least a 450w - 500w power supply , usually with a 8 pin PCIE power connection.

The CX500M meets the requirerments.
