I need new PSU for HD2900XT Crossifre and the OCZ Silencer Quad 750Watt came very highly recommended from almost anyone I asked and it also got the "Crossfire Certified" stamp and is mentioned on ATI's supported PSU page.
and you're already hitting 780 Watts, way above the 750 Watt so called "Crossfire Certified" PSU, not even taking into account the rest of the system (mobo, hdd, etc.).
Can somebody please elaborate on this ? I fully agree the 750Watt Silencer Quad is a super PSU, but based on above findings I have serious doubts it will suit my rig. Please prove me wrong because it has good price/quality ratio
it says HD2900XT Crossfired takes 581 Watt at Full Load (at stock speeds; not oc-ed).
Actually what is said was that the WHOLE SYSTEM drew 581 watts.
Test System Setup
Processor(s): Intel Core 2 Duo Q6600 @ 3GHz (333MHz x 9)
Motherboard(s): ASUS Blitz Extreme
Memory: 2 X 1GB Corsair XMS3 DDR-3 1066MHz 7-7-7-21
Hard Disk(s): Hitachi 80GB 7200RPM SATA-2
Operating System: Windows XP Professional SP2
with two HD2900XT in Crossfire
But guess I'm now going for the 100,- cheaper OCZ Silencer Quad 750W
You're sure right ? so I can OC the hell out of the Quadcore and OC the hell out of 2 2900XT's and the Silencer would be like "hey dude, is that all you've got ?!"
By the way system will be pretty basic : Q6600, Ultra 120 Extreme + Silenx Extrema 120mm, 2x 2x1GB PC6400, Maximus Formula, 2x2900xt or 2x 3870, Silencer Quad, CM690 with 3 casefans, 1x DVD-RW, 1x 500GB Samsung HDD, Vista 64
So no 5 HDD's or anything like that drawing extra juice
read a review there on the Thermaltake Thoughpower 1200; again highly recommended. It may be pretty expensive (250 Euros) but then again you're ready for a looooong time and can upgrade to whatever you like.
Really doubting 750W Silencer Quad, top PSU, 150,- Euro, or the Thoughpower 1200W, also really good, 250,-.
Think I will spent the extra 100,- and go future-proof with the latter
about that psu... it has quite a bit of juice... i suggest, you probably wont ever need to upgrade it, ever... i ahve a feeling i could switch to the worlds most powerhungry system and this could still power it...i think if i got a new computer, i'd just run 2 computers off the ones psu... lol anyway, the OCZ750 is great, but if you think the extra 100 is worth it, i say go for it.
