Thermaltake 430W Power Supply enough for e6400+7900gt OC?
Does this Thermaltake 430W Power Supply have enough juice to power a intel core 2 duo e6400 and BFG 7900GT OC? I won't be overclocking. I also have one Seagate 7200.10 320GB perpendicular recording SATA II HD and 2GIGS of OCZ Platinum 2GB Ram. Thanks
The four HD's might be pushing it especially under a gaming load.
One of the sticky's here has a link to a PSU calculator.
On another note Antec whined a little about my dead NeoPower 480 being too small for a non-OC AMD X2 4400+ and a 7800GTX with 1HD and 2 DVD drives. The calculator said I would be pulling about 450W MAX with a little insurance. Everyone else has said 480 should be no problem even if I add a 2nd HD.
I am still waiting to hear back from Antec on the cause of the failure.
I realize the e6400s don't consume a lot of power, but with that 7900GT OC in there, I would shoot for more than 18A on the single 12V rail that PSU has. That PSU has caused random reboots on 3.0ghz Pentium 4 builds with midrange graphics adapters for me in the past. Just FYI. Good luck.
Personally I'd say with an OC 7900GT you would have more to fear from the Amp load on the +12v rail than the total wattage.
I killed a Thermaltake 420w with an overclocked Athlon 1800+, 512MB, 2x HDD, and an FX5900XT.
Their PSU's I wouldn't personally recommend. I have had Antec for my last two and won't be changing anytime soon.
Do yourself a favour and get a NeoHE 550w. Have piece of mind that you have more headroom in terms of power (particularly if you want to OC your CPU too), your PSU is quieter, and that it is more efficient (save on those leccy bills).
What about Nexus NX-5000 500W? It has +12V1DC/15A and +12V2DC/16A (full info here). Would it run Core 2 Duo E6400 / 2Gb RAM / 320Gb HD / Radeon 1900 XTX (or DX10 video card) / DVD-RW / Sound Card / WLAN PCI-card without any problems? I've noticed that quite many 400-500W PSUs have two 14-18A 12V rails. Do they equal single 18-22A 12V rail PSUs? There's also Zalman ZM460B-APS 460W with 12V1/16A and 12V2/18A for 2.0 motherboards. Its specs claim that it has 20A and 22A lpeaks on those rails.
The best alternative for me would be Antec P150EC ATX case with Neo HE 430W PSU, but video card manufacturers seem to mention in product details that Radeon 1900XT(X) require at least 450W PSUs, and 430W wouldn't probably be enough in the future when DX10 cards are released.

use this to help you work it out, it gives lots of options and is easy to use.
I have first hand experience with that actually. I purchased that 430W about 3 weeks before i upgraded my machine for like 35 bucks or somethin like that? i upgraded to my 7800gt(evga) and it wasn't enough powa! we need more powa! so, i had to go purchase a 550W for about 100 bucks at compusa, lol. so, when it says it needs 450W, it MEANS it needs a 450W. Otherwise it will kick u to ur desktop while playing a game, or restart your computer. Those are two known issues for not enough power
