hi...:) 
my power supply silverstone element 850W died on me the other day, I mean it still powers up all components and the fans all spin but I dont get no display.I've tried it in another pc and I gert the same result. anyway I was wondering which of these psu's will work best for my system:

core i7 920 @2.66 GHz
OCZ3 platinum series DDR 3 pc 10666 ram @1333MHz
P6T deluxe V2 motherboard
XFX radeon HD 4890 1GB GDDR 5 graphics card
X-FI elite pro sound card
LG blu-ray multi blue disc drive
WD 2TB hard drive
samsung 500GB hard drive
Hanns G full HD 28'' monitor @1920x1200 resolution
antec skeleton pc case

these are the psu's:

www.ebuyer.com/product/152008

www.ebuyer.com/product/204354

www.ebuyer.com/product/152506

I remember that I need at least dual +12v rails to power something ( I think it was either motherboard or cpu ).

thanx for any feed back...;)

Hi.

Here are the system requirements for the 4890.

ATI Radeon™ HD 4890 Graphics System Requirements

PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard
500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for ATI CrossFireX™ technology in dual mode)
Certified power supplies are recommended. Refer to http://support.amd.com/us/certified/power-supplies/Page... for a list of Certified products
Minimum 1GB of system memory
Installation software requires CD-ROM drive
DVD playback requires DVD drive
Blu-ray™ playback requires Blu-ray drive
For a complete ATI CrossFireX™ system, a second ATI Radeon™ HD 4890 graphics card, an ATI CrossFireX Ready motherboard and one ATI CrossFireX Bridge Interconnect cable per graphics card (included) are required


The recommended PSU is for the entire system. OCZ don't make very good PSU I would go with one of this:

1- Corsair 650W HX Modular PSU
2- Corsair 650W TX Series PSU

Both can handle ur rig and a future upgrade to 57xx series or 58xx series and Crossfire.

OK - to answer your question any of those PSUs would work with your rig. None of them would support crossfire. (you could run 2x Radeon 5770 though because it only uses 1 x 6pin PCIe connector, 4890 requires 1x6pin and 1x8pin IIRC). I would get the ModXtreme one though, for better cable management (although I have heard that modular PSUs can be less efficient)

Im using 2 OCZ PSUs in two of the machines in the office where I work, I built both machines myself. One is a 700w ModXtreme, and the other is a 400w StealthXtreme. The OCZ PSUs have been great value for money for me. But for my home computer (see bio) I have a Corsair, which would wipe the floor with oether of my OCZs.

i've looked into the corsairs but on the P6T deluxe V2 motherboard forums, alot of poeple have been complaiming that corsair psu's don't work properly or something like that so I thought I would go for the OCZ psu's

Both Corsair and Antec have 8pin 12V that is the same connector that the P6T Deluxe V2 needs.
