GTX 970 and 460W power supply

[Dafox481]

So I'm looking to get a new EVGA SSC GTX 970 but the power supply in my computer is only 460 watts. And even worse, it's the one that came with my pre-built PC from HP. Terrible, I know. But from what I can tell, it's fairly decent. I haven't had power related issues with my computer whatsoever, but I'm just wondering if a cheap 460W power supply will be able to run a GTX 970. 

 

In case it's needed, my PC model is the HP Envy 700-239  http://support.hp.com/sk-en/document/c04119451 < That's the link to the specs

 

Thanks in advance for any help.

No, not recommended. Get a new one.

I'd imagine the included HP 460W PSU would be a Delta so a PSU upgrade will not be needed unless the PSU doesn't have 2 6pin PCIe power connectors or what ever the GTX 970 requires.

 

If the PSU isn't Delta, Seasonic or Superflower I'd probably upgrade just in case.

 

I highly recommended one of these Power Supplies.

Edit: From looking at this image, I am pretty sure your PSU will be a delta.

Just Googled that PC for a bit and it looks to be a Delta PSU, which is one of the more reputable PSU companies up there with Seasonic and SuperFlower.

 

I believe the GTX 970 SSC needs one 8-pin (6+2 would work as well) + one 6-pin power connector. So if the Delta PSU doesn't have those, then you need a new one.

 

Anyway, what's the price of the GTX 970? Likely you can get a custom RX 480 for cheaper that'll only require an 8-pin.

For the love all things holy. Never use a Power Supply that comes with Computers already installed especially HP. But you are probably new to Computers so it's ok. Usually a 970 will require a 8 pin PCIE cable and a 6 Pin PCIE cable. Usually all newer Power supplies have the sufficient cables needed. The power supply that comes with your PC probably doesn't even have one Pcie

For indication, I'm running a 980Ti in a system with 450W PSU... I wouldn't worry about a 970 unless you're doing insane overclocks on it.

If you're going to put some big overclocks, or already have a power-hungry CPU, I'd suggest to maybe upgrade to be safe, otherwise, you're good.
