Summary: after having this for about a week (at the time) the PCIe slot decided to stop working. after thinking it was the graphics card. sending it back to evga and getting it back. the graphics card decided to stop working again. it turns out, it is this power supply. every 2-4 days i have to open my tower (after doing a hard shutdown) and switch PCIe power ports on the power supply itself. each time i have to do this i am damaging my OS more and more.
Summary: This power supply normally runs very quiet except sounds like a jet engine under load. I am running two GTX 560 TIs in SLI, and after about 15 minutes of Battlefield 3 the fan kicks in and my computer sounds like it's going to take off. It's loud enough that the guys that I game with can hear it over teamspeak. I've decided to return it and find a different power supply that is up to the task. Here are my specs in case you think I might be overloading the psu.
Summary: If you are looking for a portable typhoon for < 100£, this is a must buy. It is seriously loud under load and often won't back down until a system restart. I am rmaing mine just in case, but the voice on the net tells that is a model issue, rather than a faulty unit. If you are looking at spending this kind of budget on a PSU you can as well throw in some extra money and get a very good one that won't keep whoever is in the room next to yours aware of your activity on...
Summary: Bought this to power my Crossfire system. 2 x XFX HD Radeons 5870s. I already was using a XFX 650w PSU in this system and it works perfect but my 2nd PC was in need of a new PSU so decided to get this OCZ 750w and put the 650w in the 2nd PC. Completely modular, yes it is, no attached cables at all, excellent for managing cables. So I installed it and powered it up. First impressions was it's a bit louder than the XFX but not a big problem.
Summary: Estuve buscando una Fuente de Alimentación (F. de A. / P. S.) de entre 650 y 750W para mi PC que fuera modular 100%, o sea con todos los conectores enchufables. Vi una Coolmax que me gustaba en Amazon.com pero me dijeron que no la podían enviar a España y no la tenían en catálogo en Amazón.es. Opté por esta OCZ por ser la más cercana a lo que yo buscaba y además tenía en Amazon.es el mejor precio. Sustituí mi anterior F. de A.
