That's an alright power supply. First, it won't blow up in your face. More often than not, the stated info on the PSU is accurate. Then it's delta. They can make very high quality power supplies if they need to (they build PSU's for a lot of comps like antec) but usually the OEM ones they make, although not very efficient or high in quality, they'll do their job.
Just don't expect it to power anything above a mid range card.
