I need PSU/Graphics Card advice

ivext · Jun 17, 2013

Ok, So I've been battling with my PC for the past few days. Before anything here are my specs:

-Gigabyte Intel i5 Quadcore 2500k 3.3GHz
-Windows 7 64bit
-Intel (R) HD Graphics 3000
-500W "BREEZE" PSU (that's the name on the physical PSU)

Recently installed:

-PNY Performance Edition GeForce GTX 650 1GB GDDR5 PCIE 3.0

Issue: The card came with a V shaped external power connector. If I connect the two outlets to the PC, it turns on and off continuously and/or no signal on the screen. If I connect only one, it looks as though it functions (because of the fan running). The problem is that the computer does not recognize the graphics card at all.

Help I don't know what's wrong anymore.

I think you do not have enough power from your PSU. That seems to be a VERY cheap, low-end POS power supply, and is probably not putting out anywhere near its rated power.

I think the PSU might be the problem.

As such, you should upgrade

XFX Core Edition PRO550W (P1-550S-XXB9) 550W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Active PFC Power Supply.

Get rid of the BREEZE and grab this quality PSU.

For a system using a single GeForce GTX 650 graphics card NVIDIA specifies a minimum of a 400 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 20 Amps or greater and that has at least one 6-pin PCI Express supplementary power connector.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most important factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

The BREEZE 500W (P4-500W), with its maximum combined +12 Volt continuous current rating of 14 Amps and with NO PCI Express supplementary power connectors, is grossly insufficient to power your system configuration with a single GeForce GTX 650 graphics card.

The XFX Core Edition PRO550W (P1-550S-XXB9), that @SR-71 Blackbird suggested, is an excellent choice.

Thanks to everyone for the suggestions. I definitely appreciate the specifics.
