I'm looking for a replacement for my OCZ Fatal1ty psu.
I came across Sharkoon, but I'm not really fammiliar with PSU's.
Would this be a good psu?
My current system runs well on a 550W psu, so the wattage shouldn't really be a problem.
I wouldn't touch it with a 10 foot pole. Only get a PSU from a proven reliable brand such as Antec, Corsair, Enermax or Seasonic (best ones). How much are you looking to spend on a PSU?
You should also know that super cheap PSUs cannot reliably output their labeled wattages. Hell many OCZ units go out of ATX specification when running their labeled wattage. You've seen those $20 "500W" PSUs right? Look at what they're really capable of. About 200W.
And what about Silverstone?
I'm looking for a PSU that has 4x pci-e connector (6 or 8 pin doens't matter)
Let me say a max of 85€/$
Silverstone is a mixed bag like most companies. For about $85 get an Antec TruePower New 650W. It's a great PSU built by Seasonic with only Chemi-Con Japanese capacitors, DC-DC converter, dual layered PCB with decent soldering and it's very capable. An alternative to this (if it costs too much or can't be found) is the Corsair HX650 which isn't quite as good in performance, but has more modular connections and might cost more.
Modular isn't required 😀
I'm gonna buy this one. A friend of me reviewed it and said it is better than the antec you mention.
Little question still, 4-pin cpu power or 8-pin cpu power? What is the difference, and is it really needed to connect an 8-pin if the connector is an 8 pin?
