Closed Palit GTX 670 with HEC Raptor R500, is this ok? Tags: Graphics Cards Gtx Palit Raptor Graphics Last response: January 6, 2013 2:28 PM in Graphics & Displays Share bcarb January 5, 2013 1:12:01 PM In the Palit GTX 670 Jetstream, it requires 500w PSU with minimum 12V current rating of 30A. I will be upgrading but want to know if I can keep my PSU. Would this be fine with a 3rd gen i5 system (no overclocking) using a HEC Raptor R500 PSU? I have few HDD drives,SSD and fans but will only use single gpu. What does the minimum 12V current rating (30A) mean? Do I need to add the rating per rail or is the 19A rated in HEC the one to check? The HEC Raptor R500 specs are: +3.3V = 22A; + 5V = 15A; Combined: 130W +12V1 = 19A; +12V2 = 19A; Combined: 384W -12V = 0.3A; +5Vsb = 2.0A; --------------------------Total Output Power: 500W Thanks! =) More about : palit gtx 670 hec raptor r500 Best solution siddharthmukul007 a b U Graphics card January 5, 2013 1:39:40 PM use this link: http://www.extreme.outervision.com/psucalculatorlite.js... always remember no psu in this world has 100% efficiency. it ranges from 80-90% bcarb January 5, 2013 1:53:12 PM Thanks. From the link I got 430W. I'm wondering if the two 19A rating per 12V rail of the HEC Raptor is enough for the Palit Jetstream GTX670 30A minimum requirement. Is it wise to get a new PSU or no need to spend on a new one?
