Gigabyte HD 6850 and Thermaltake Litepower 450w.

post #1 of 10
Thread Starter 
Hi, guys this is my first post here, so don't flame. I'm currently upgrading my PC, specs are in my signature. So, I was going to upgrade to the Gigabyte HD 6850 OC version, but there was one thing concerning me. That one thing is my PSU, which is the Thermaltake Litepower 450W, which I received with my Thermaltake V3 BE Case, so is there any chance this little thing can handle the hd 6850, until I purchase a new PSU, as I'm low on funds atm, and the price of the HD 6850 is starting to increase (been looking at it for a couple of months). I've searched a lot of places for answers, but it's generally different branded PSUs which have been considered.

Here are the details on rails for my PSU.

Yes, it's completely fine. Also I see no reason you would get flamed, welcome to the forum! Click the picture and you will see the full article. The test system they are using is a Core i7 970 (hexacore with hyperthreading) along with the X58 platform, which is going to consume a good bit more power than your current setup.

Thanks heaps man! Haha, its because I generally see newbs posting on other forums, majority of the time not searching(but i did of course), so they get flamed, but not here, gotta love this forum . Can't wait to get the card now, never realised how low power consumption is, even in crossfire two 6850s consume less power than a stock GTX 470. Again, thanks heaps for the advice

Does the psu have 6-pin connectors? If not definitely upgrade psu. The you don't want to be running off of molex adapters.

Edit: your psu seems to have only one 6-pin connectors and the 6870 needs 2. If I were you I would buy a higher performance psu.

If you're interested check out this link for some recommendations of 750w modular psu's. 750w will give you plenty of overhead for future upgrades and modular is just awesome.

well, if i was to get the 6870 i would of but since I'm getting the 6850 i wouldn't need such a high powered psu. But, another thing is the rig im building atm, will have no further upgrades made to it ever again, since my next build will be when i start uni in 2013 (most likely ivy bridge or whatever they have by that time).

Oh and thanks for the link anyways

You're absolutely right. The gigabyte hd6850 Oc edition only requires one 6-pin connector. Your psu is fine.

Enjoy the upgrade, and you're gonna love it!

6850 is not a power hungry card and you'll be fine.
