Molex and SATA question

I am considering putting a Radeon 6970 into my machine ($240 au rather than $400+ for the 7900), and I have a 680w PSU. Weirdly enough though, I have a 6 pin pcie connector, but only one 4 pin molex and 6 SATA connectors. Would I able to use a SATA to molex adaptor to run an 8 pin pcie adaptor to run the 6970?

you would but i'd be very interested in what psu you have, as there might be a very good reason for your cable configuration.

Would there be any negative effects if I did this? Can't look at my PSU until I get home. All I have running off the SATA power is my hdd and DVD-RW drive.

if your psu is not good then it could kill your whole system-worst case, die-second worst case, or be ok.

Never herd of the brand, And it is a cheap one. I kinda think it'll work but perhaps consider getting a better one in the short future.

Hdd is coming of the SATA cables, and the DVD-RW drive is coming off the other molex using a molex to SATA adapter. I'll come off the DVD-RW as it doesn't get used as much as my hdd.

Or would I be better off putting an extension on my SATA power for the DVD drive and using the other molex strictly for the 6970 I want?

It lists nothing with regards to the 12V amps available. Which cables you use does not really matter all that much.

Do you have the funds to replace your whole system?

With regards to using it for the short term, be aware that it could fail instantly.

IMO not worth the risk.

NO NO NO

Get a good 600W PSU and you'll have plenty of power.

http://www.hardwaresecrets.com/article/TiVECO-TVPS450-P... is how wrong it can go, they have worse. Look for a 600W thats affordable and check with hardwaresecrets reviews.

UGH! - Bad decision

PSU quality far more important than watts.

per delluser1(status addict) from an older thread:

It's a discontinued model ( can't be found on Tt's site ) with a 65%+ efficiency rating and not really a 700 watt unit.
Combined output on the 12v is about 39 amps based on 5v and 3.3v combined max output ( may be capable of a little more on the 12v )
Specs here
It should do, for how long is anybody's guess.
