Hi Tomshardware,

I have a bit of a problem. I've looked around on the internet for an answer but i cant find one. my motherboard has an 8 pin CPU power slot. I have a power supply with an 8 pin power connector but it dousnt work =|. so now i have to use my old one. but it dousnt have an 8 pin power connector. i can fit it's 4 pin power connector into the motherboard. but im a bit worried it wont be sufficient for my cpu, so i havn't actually used the new mobo yet. I've got a few options.

1. Should I buy an adapter? like molex to 8 pin?
2. Should I buy a new PSU?



MOBO: Gigabyte GA-990FXA-UD3
CPU: AMD FX 8120 3.1Ghz
PSU: Thermaltake 500w HERE: http://www.pccasegear.com/index.php?main_page=product_i...


Thanks in advance.

For a system using a single GeForce GTX 660 (non-Ti) graphics card NVIDIA specifies a minimum of a 450 Watt or greater power supply that has a combined +12 Volt continuous current rating of 24 Amps or greater and that has at least one 6-pin PCI Express supplementary power connector.

For a system using two GeForce GTX 660 (non-Ti) graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 600 Watt or greater power supply that has a combined +12 Volt continuous current rating of 36 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated @ 45°C-50°C ambient temperature, is the most important factor.

The Antec VP Series 550W (VP550P), with its combined +12 Volt continuous current rating of 45 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single GeForce GTX 660. It is also more than sufficient to power your system configuration with two GeForce GTX 660 in 2-way SLI mode.

Antec VP550P 550W Power Supply for $65.00 AUD

^ Antec makes good PSU's.

This corsair is on sale for $38 with MIR.

This Silverstone is modular and $70 after MIR.

For SLI, I run this 750w PSU:

~$100 after MIR.


This 750w Antec is an impressive value @ $70
