Antec TruePower 550w 20-pin ATX12v?

It may say it on the site, but the site doesnt like the model number, so im to 100% on it, but is this "Antec TruePower 550w" going to work with my Gigabyte GA-K8NS Ultra-939?

Mobo:
#1 ATX power connector and ATX 12V connector (20 Pin)


Edit:
Oh ya i found it for 90 bucks or so, and with a 5 dollar promotion i found its only 85 with free shiping!

The power supply likely comes with an adaptor to convert the 24pin psu to a 20 pin layout. If the system you're going to power is in your sig, I'd definately go with a 500w fortron. Buy it from either www.actbuy.com or www.ewiz.com (i went with act buy) as they're both under $80 including shipping. You won't be dissapointed.
