Do you think a 550 watt power supply will work with the specs below? =Specs= ||MB|| ASUS P5LD2 Deluxe ||CPU|| Intel Extreme Edition ||RAM|| Kingston DDR2 2x 1GB ||GFX|| NVIDIA GeForce 8800 GTX ||HDD|| WD Raptor 2x 78GB
wit the 8800 requiring 2 PCI express connectors, 550 is probably pushing it, you might want to consider over 600. i dont know whether the card will fit or not, i thinks its longer tham ythe 7950 GX2, which is a LONG card
what 550 is it? anyone can claim 550. it's the quality. You need at least 30a on +12v to power a single 8800GTX.
Should be ok. nVidia used to have a list of 8800-series approved PSU's for 100% certainty, but it seems to have 404'd in the last few days.
If you want to buy a second 8800 GTX it is not enough, I would take a PSU with a capacity of approx. 700W, then your are prepared for the future.
This thread is so full of crap it's unbelievable. People, take a look at the power requirements of tims bench setup in the G80 review, they used not much more then 300W at full load. Granted there's gonna be a bit more stuff in this box, but I'd be surprised if a 400 didn't cover it, and a 500W most certainly will with space for expansion. Of course SLI changes things, but SLI 8800's are miles out of everyones league for now anyway.
One thing worth noting on power supplies is that most list there maximum power output on boxes while the Geforce 8800GTX review here tested average continual power consumption. A power supply that is rated for a 400W maximum output may have troubles dealing with a 300W continual output. A 550W power supply (which I assume is maximum output) is recommended by nVidia as takes into account a fairly high end system build with a bit of room to spare in terms of dealing with continual power output. Also worth noting is that power supply efficiency changes with its temperature. An open test bench with a low ambient temperature will have a higher efficiency (and thus less power lost in the AC-DC conversion) than in an enclosed case system.
I meant for the entire system. Granted, i'd try to use something with more than 30a. Maybe the enhance ENS-5150, since it's still so cheap and provides 36 amps.
I went for the antec neoHE 550W 12V1 38A 12V2 19A 5V 26A 32,9 dBa at 266W/20cm efficiency 266W 89% efficiency 339W 77,4% 117 euro
The 8800GTX in a powerfull bench setup consumes about 320W of power under full load, 800W is overkill by a factor of 2. 550W should definately be enough for that system. You got fooled into buying a 1.1Kw PSU(sorry, it's harsh, but it's true) - there's no need for others to end up in the same boat though.
