Hello, I have bought a Gigabyte GeForce GTX 670 OC 2Gb graphics card, the windforce one with 3 fans. It has a 6 pin power slot and an 8 pin power slot, however my psu only supplies one 6 pin cable. The psu is a standard ATX 620 power supply. There are a few various cables that are free but im not sure if i can use an adapter on them.

I have one of this cable free: http://www.electronic-products-design.com/wp-content/uploads/floppy-berg-mini-molex.jpg

One of this cable free: http://upload.wikimedia.org/wikipedia/commons/3/31/Molex_female_connector.jpg (my ones colour is black not white)

And two of these free: http://www.quietpc.com/images/products/sata-molex-hdd-cable-large.jpg (the black one on the left).

Would i be able to buy some adapter that connects to any of these free cables and is a 6+2 socket on the other side, or do i have to buy a new power supply? My motherboard is an Asrock H61m-S and i have an intel i5 cpu from about 3-4 years ago.

Thank you.
 
Solution
27A (assuming it can really output that.) * 12V = 324W. REALLY low output for a "620W" PSU. Again, I wouldn't use it. A new PSU is in order.

I wish i could post photos from my phone, it literally just says on the sticker with all the info:

Model: ATX 620
ATX Power Supply
AC Input: 230V 50Hz 5A
DC Output: +3.3V 22A
+5V 40A
+12V 27A
- 12V 1.2A
-5V ---
+ 5V SB 2.3A
And on the side theres a random code that could possibly be a model number or something: S/N:64794437

Thank you.

It has a big fan in the middle facing all the motherboard and everything, it is a silver/grey colour and im not sure what sleeved mean but all the cords come out of one hole and it is not modular with the connections. I have currently been running a GTX 550Ti for about 3-4 years so far with no problems. Thanks.

If it is most likely better to just go for a new power supply, will any of these be compatible with my mother board:
Aerocool GT700S 700W Power Supply
EVGA SuperNOVA 750W B2 Power Supply
Corsair CX-750 Modular 80+ Bronze Power Supply

it might be a korean true rated?.. sleeved means the cables, if they are sleeved with black or just are just bare cables.

anyway i think the 27 amps on the single 12v rails is kinda low for a gtx 670 you must get at least 35-50 amps on the 12v rail to effectively run a gtx 670
