This is my new vid card

http://www.asus.com/Graphics_Cards/EAH6850_DC2DIS1GD5/

I have a 3 yr old HP computer HP h8-1160t bought at Costco

I tried putting in the card, sunggly in there, power plug plugged in.....turn the PC on and nothing pops on the screen. It's just black cycling through the inputs (HDMI, Digital, Analog...etc)

I'm guess this HP just doesn't have the power for this card?

It's sad...the card isn't super new, but I'm thinking my PC is a POS 😛
 
Your processor is 95 watts & card is around 150 watts, add the rest of the system, and there's no way a 300 will work.

lol @ people freaking out about vid card power requirements. 6850 is definitely in the lower end of power consumption range, I'd say 80-100w in typical 3d load (120 in furmark, unrealistic)
 
It is not just that it is a 300w model. It is a 3yr old cheapo HP 300w model that probably never did 300w in the first place.
 
Maybe so, but how do you explain it not being able to provide 15w of power? Just using simple logic, which situation is more likely?

1. Somehow, at the bootup 3d card goes into 100% 3d mode, running furmark/3dmark before the winOS even loaded.
2. Power supply failed already, providing precisely enough power for cpu only
3. Potentially old motherboard in an OEM computer doesnt recognize new pci-e 2.0+ standards, and BIOS update is needed
4. Video card is DOA

Perhaps I am ignorant of electronics engineering, and video card DOES actually pull 100% of max power in the first second of boot?

Where does all the 3d data come from in the first 3 seconds of boot to load onto its memory chips? Does it really need to power ALL of their 1024 shader processors, if so, what do all those shaders process besides some plain white text?

During post all devices will run at full bore until power management features go active. Even fans will be running 100%. So even for people buying just enough PSU to supply their whole system you still need to account for every max watt your system can consume even if while in the OS you might only ever hit 80%.

Its not about actually computing information. Its all because until told otherwise they run at 100%.

It could be worse. A decade ago pretty much your computer was at 100% or it was off. No compromise.
 
Can't you just look on the side of the psu and see what the amps are on the 12 volt rails? If the psu has a six pin pci-e connector, I doubt it is a 300 watt model.
 
looking by symptom, which is similar to when a card isn't connected to external power (as stated by other graphics card manual, pc won't boot), suggests that it didn't receive enough power or any power at all.
 
When I look up the pictures of that card, it requires two 6-pin power connections. I would be quite surprised if a generic 300-watt power supply in an HP would have both of those connections.

About boot power, I did find a youtube video that might help here. Pay attention to the ratios more than the numbers.

To save 5 minutes of viewing, here are his results in watts:
BIOS load: 300
Idle: 150
Max: 440

So, when booting you will have not quite max load numbers, but they do show that the video card and CPU are using a good bit of power until the OS tells them how to manage it.

Bottom line, what you are seeing and the hardware you have are a very strong indicator that a more powerful power supply will fix your problems.
 
My card does have two pin connectors but I only have 1 to plug into the card. I updated the BIOS, as per a few suggestions, and nothing.

Does anyone know if I can buy a new power supply for this HP?

I'd rather buy a power supply than build a new PC....very tight on money

Thanks everyone
 
If it has 2 PCIe connecter...then you NEED both hooked up, otherwise....no video!

FYI do you have a PCIe to molinex adapter - card usually comes with 1. Try using it - if you have - to connect to other PCIe connector. Might solve your problems - at least you should get video signal....

If you don't have one, PM me with your address and I'll send you one....I've got a bunch!

Yeah this is definitely it. The card won't work without both power cables connected. While a molex to pcie adaptor might get the card to turn on, the card still needs a 500w or greater PSU (per AMD). So either way, you need a new power supply.

The good new is that it looks like your HP uses a standard ATX PSU, which means you can get pretty much any aftermarket unit. A couple good brands to look into would be Seasonic, Corsair, and Antec to get you started. I'd probably go for a modular unit as there isn't usually a lot of extra space in those HP cases.
 
So, my power supply says 460 watts on the side, but there isn't another connector for the molex to 6-pin that came with the newer card.

So, guess I'm buying a new power supply.

How do I know the new power supply will have enough "wire guts" coming out of it to adequately power the card?
