Can I run this graphic card with my PSU?

My PSU is 450W and want to run a Radeon HD 6850 thus, upgrading from a Radeon HD 6670. Do I have enough juice on my unit to run it?

Hi,
Did you refer to the spec's sheet of the card ?
I doubt they are very different between those two versions.

I don't think that the difference is huge. All I was going for was the sharper images. Also, I wanted to know if the PSU that I'm currently is actually powerful enough for either card, especially the newer one.

Hi,
Post a link to the new card I hate looking them up it might be different manufacture....

There's this link to the card.
AMD Radeonâ„¢ HD 6850 Graphics

Hi,
They don't say really on the foot note

1. AMD Eyefinity technology works with games that support non-standard aspect ratios, which is required for panning across multiple displays. To enable more than two displays, additional panels with native DisplayPort™ connectors, and/or DisplayPort™ compliant active adapters to convert your monitor's native input to your cards DisplayPort™ or Mini-DisplayPort™ connector(s), are required. SLS ("Single Large Surface") functionality requires an identical display resolution on all configured displays.
2. AMD App Acceleration is a set of technologies designed to improve video quality and enhance application performance. Full enablement of some features requires support for AMD Accelerated Parallel Processing (APP) technology and/or AMD's Universal Video Decoder (UVD).
3. AMD PowerPlay™ and AMD Accelerated Parallel Processing (APP) are technology platforms that include a broad set of capabilities offered by certain AMD Radeon™ HD GPUs. Not all products have all features and full enablement of some capabilities and may require complementary products.
4. AMD HD3D is a technology designed to enable stereoscopic 3D support in games, movies and/or photos. Requires 3D stereo drivers, glasses, and display. Not all features may be supported on all components or systems - check with your component or system manufacturer for specific model capabilities and supported technologies. A list of supported stereoscopic 3D hardware is available at http://www.amd.com/HD3D.
5. AMD CrossFireX™ technology requires an AMD CrossFireX Ready motherboard, an AMD CrossFireX™ Bridge Interconnect (for each additional graphics card) and may require a specialized power supply.
6. Minimum recommended system power supply wattage is based on the specific graphics card and the typical power requirements of other system components. Your system may require more or less power. OEM and other pre-assembled PCs may have different power requirements.

Hi,
Here it is 500w

• PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard
• 500 Watt or greater power supply recommended⁶
• Certified power supplies are recommended. Refer to http://support.amd.com/en-us/recommended/power-supplies for a list of Certified products
• Minimum 1GB of system memory
• Installation software requires CD-ROM drive, a keyboard, a mouse and a display
• DVD playback requires DVD drive and a DVD
• Blu-ray™ playback requires Blu-ray drive and a Blu-ray disc
• For an AMD CrossFireX™ system, a second AMD Radeon™ HD 6800 Series graphics card, an AMD CrossFireX™ Ready motherboard and one AMD CrossFireX™ Bridge Interconnect cable is required

Thanks so much for your help! �� Now I know that I need to get a 500 watts psu then. I appreciate the help!!

Hi,
Post to your existing card it might be the same recommended size :)

Your 450W PSU may be adequate. It would be helpful if you told us what PSU it is. (There's usually a plaque on the PSU that lists its model and specs.) If you were to upgrade, it would make sense to go larger than the suggested minimum. PSUs aren't created equal: a good 450W one may be more suitable than a poor 600W one. (The power specs aren't regulated by any law.)

Example: good 450W: https://www.newegg.com/Product/Produ...0967-_-Product Rated at 37A on the +12V rail.

Cheap 600W: https://www.newegg.com/Product/Produ...0967-_-Product 30A on the +12V rail.

The suggested minimum for the 6670 is 400W.

One thing that you'd need with a 6850 is an auxiliary 6 pin PCI-E power connector. (Or, and adapter to take two HD power connections into a single PCI-E one.)

I see that the 6850 was introduced more than 7 years ago. I hope that it will be a free upgrade. An nVidia GT 1030 (low end current model) would have better performance. The recommended PSU for the 1030 is 300W and up.
