According to this, the 12V rails combined can output 404W, about 33A. Might be ok, but it'll be cutting it pretty close.

I'm planning to grab a 5850 sapphire toxic this weekend and wondered if this PSU:

http://www.tigerdirect.com/applicati...984&CatId=1079

is it good enough o_O?

AMD athlon X4 630
1 HDD // DVD-RW and that's about it...

that is all folks !

WHY would you buy a PSU from a company who is going belly-up?

Oh yeah...if you don't already have the PSU...DON"T BUY IT. If you do already have it, it should be ok.

BTW all but one of the pictures on TigerDirect's page for that PSU are pictures of the BFG MX or LS...not the GX. The GX DOES NOT have Active PFC. another reason to hate TigerDirect...

Anyway, the GX is closer to a 450W PSU at room temperature.

I already have the PSU...it's on the sig. :(, 2 years of use and going strong on my browsing rig. My plan is to grab another one through FS/FT forum because: it's modular...affordable.

But I can stretch my wallet a bit, because i'm going to use the GPU on the HTPC rig.

OK, since you already have one...yes, it should be enough for what you've listed.

Don't get another one used.

Is this cheap enough for you? Corsair Builder Series 600W, $50 AR.
40A on the 12V rail should be enough with a bit of headroom.

You most likely won't have any headroom with the BFG PSU and pushing a PSU to its max is never a good thing in the long run.

Fixed. :(

Anyway, the GX is closer to a 450W PSU at room temperature.

I thought it was "rated" at 550W 25°C, meaning 450W "real world" power. Dunno, JG would know for sure.

Not that it was running higher than room temperature, but at a LAN party I once load tested three PSUs.

The back story is that a case/PSU was donated to the event as a prize. The PSU was basically a Deer or Powmax or whatever (really short, red label without brand, "450W," rear grill stamped out of casing, came with $30 case). I was with BFG at the time and got permission from the director of marketing to donate a GS450 as a replacement for that crappy PSU, and got permission and OJT from JG on using one of BFG's Sun Moon load testers. Got the thing programmed for 350W total (the continuous rating for the GS450).

At the LAN, hooked up the GS450 and it ran just fine. Hooked up the mystery "450W" PSU at 275W (75W was on the 6-pin PCIe which it didn't have) and after merely a couple minutes it failed. Sadly no big flash/noise/smoke. Voltages just went haywire before it quietly gave up the magic smoke(less). Someone had an HP rig there with some 300W Bestec or something, and he wanted me to test it. Also worked just fine (at 275W). Then, hooked the GS450 back up and just let it run during the LAN. Awarded it to the winner of the (now PSU-less) case at the end of the event.

I suppose you'd know about the status of the company. Sad to see them fold. I knew from various reports that it was happening...I didn't know they were completely gone.

when I said room temperature, I actually meant normal computer operating temperature
