Possible to replace GT640 with GTX 960?

[Rambor]

Hey, so my plan is to replace my GT 640 graphics card with the GTX 960 graphics card in my HP envy h8 desktop pc (460W power supply). I was wondering if this is possible as i'm new to the pc hardware world.

Thanks in regards!

Assuming the HP PSU is good quality, I see no reason you can't. As long as you have the room for the length of the card that you choose. Measure to be sure.

Btw, check that your PSU has the necessary 6/8 pin connectors for the card you choose. If not, then the PSU is probably over-rated.

System Power Supply Requirements for a single GeForce GTX 960
• NVIDIA specifies a minimum of a 400 Watt or greater system power supply. (Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz 130 Watt TDP processor.)
• the system power supply must also have a maximum combined +12 Volt continuous current rating of 28 Amps or greater
• the system power supply should also have at least one 75-Watt 6-pin PCI Express supplementary power connector. There are some non-reference design cards that require two 75 Watt 6-pin PCI Express supplementary power connectors (e.g. Gigabyte GTX 960 G1 Gaming 2 GB [GV-N960G1 GAMING-2GD REV.1.0], Inno3D iChill Geforce GTX 960 2GB Ultra) or one 150-Watt 8-pin PCI Express supplementary power connector (e.g. EVGA GTX 960 SSC 2 GB [02G-P4-2966-KR], MSI GTX 960 Gaming OC 2 GB [GTX 960 GAMING 2G]).

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical 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.

Your HP OEM 460W PSU has a maximum combined +12 Volt continuous current rating of 30 Amps and has only one 75-Watt 6-pin PCI Express supplementary power connector.

Thanks for the fast answers.
The PSU is a HP AcBel PCA246 460 Watt Power Supply an has an extra 6 pin connector (don't know if it's 75W though). It also has enough continuous rating on the +12V I think (18, 12 and 10). So am I good to go with the GTX 960?

According to NVIDIA's system power supply requirements, yes. As long as it's an NVIDIA Reference Design card.

The 6-pin PCI-E power connector is 75-Watts as defined by the PCI Express Standards.

If those are amps, you should be good. Hopefully the total wattage of the +12v rail(s) is at least 300W. Some GTX 960 require an 8 pin connector (150W) instead of a 6 pin (75W). The New Maxwell-equipped GTX 960 is a power sipping GPU anyway: http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-960/specifications

Personally, I would have no issue going with the GTX 960 if that were my system.
