I tried this PSU calculator: http://extreme.outervision.com/psucalculatorlite.jsp
and it seems like it is giving me a low estimate for the power supply I would need to run the following system:
Core i7 920 stock
"high end desktop"
2 sticks ddr3
one sata hard drive
one radeon hd 5870
dvd burner
1 PCI card (I did this to represent a sound card)
2 regular performance 250mm fans
1 regular performance 120 mm fan
capacitor aging of 20%
90% system load
It said I needed a 395 watt (continuous I am assuming) to run it. I have an Antec TruePower Trio 550 watt (continuous) right now and the following are my specs:
Intel Core 2 Duo E6600 2.4 overclocked to 3.15GHz, 1.35 vcore (just guessed, don't remember)
8800GT 512MB
3 sticks ddr2
one sata drive
one dvd burner
asus p5b deluxe wifi-ap (don't know if that qualifies for "high end desktop but I will use that anyway)
one sound card
3 120mm fans (LED)
2 80mm fans (LED)
floppy drive
35% capacitor aging (3 years old)
The one for my current system says 383. Why then do I have a 550 watt? Is that accurate?
Also, I know the PSU rails have a lot to do with requirements as well. Let's say I have one 12V rail. In what situation would only one be bad and why? I know very basic stuff like if you have parallel circuits the voltage is the same on all of the wires, does this have to do with the amperage available per rail?
Thanks. I was building a mock i7 system and it got me thinking.
