Title: Please recommend PSU for 4x 7950's Post by: Mortimer452 on January 22, 2014, 03:43:33 PM Good morning all
Can I get some recommendations on a PSU for my 4x 7950 rig setup. I originally purchased a cheaper CoolMax 1200W 80+ certified PSU and blew it up after just a day of mining. I am "getting by" on 2x REALLY CHEAP Kingwin 750W PSU's (came free with cards) but I don't expect these to last long either - they already occasionally glitch out and reboot my machine, even with just 3 cards running. I am looking at the ThermalTake SP-1200M, any experience with this brand? Any other recommendations? Trying to stay under $250.

All of these units are $250 and under: XFX ProSeries 1250w (http://www.newegg.com/Product/Product.aspx?Item=N82E16817207020) (Seasonic rebrand) Out of Stock @ newegg (maybe fine elsewhere or set auto-notify) LEPA G1200-MA (http://www.newegg.com/Product/Product.aspx?Item=N82E16817494011) (Enermax rebrand) Out of Stock @ newegg (maybe fine elsewhere or set auto-notify) SilverStone Strider Gold SST-ST1200-G (http://www.newegg.com/Product/Product.aspx?Item=N82E16817256082) In stock Rosewill LIGHTNING-1300 1300W (http://www.newegg.com/Product/Product.aspx?Item=N82E16817182063) Out of Stock @ newegg (set auto-notify) All good PSUs and up to the task. 4 7950s will come very close to 900-1kw and thus a 1000w unit is really on the red line. Most 1200w units are only a couple bucks cheaper as it is. The LEPA is best bang/buck followed by the Silverstone. I am currently using 2 of the LEPAs and for 9 months now they have been going strong @ roughly 1kw load each. I have a Silverstone 1500w unit on 4 290s and it's been rock solid for the last week. I would expect the 1200w unit to be of the same build quality. The Rosewill units are Newegg's house-brand so you won't find them anywhere else, but regardless they are worth mentioning as they have good user feedback / 3rd party reviews that reflect a solid build quality.
