We really need to know the rest of your build to comment accurately on PSU's, but I'm pretty sure the strider is a tier 3 PSU

If a PSU seems like it's really cheap for the wattage, there is a high likelihood that it's sup-par. If I was looking for a 1000w PSU on PCCG, i'd get the EVGA SuperNOVA 1000W G2 Gold Power Supply $259. That being said, i've got a 750w strider in my rig that hasn't caused me any trouble, but it would be running at about 50% draw. What is the rest of your build? You might not even need 1000w.
