View Full Version : Question on PSU is this good enough??
I just got in my QX6850 CPU and 2 8800 Ultra superclocked cards i have a Seasonic S12 Series S12-500W 500W Power Supply does anyone know is this going to be good enough to handle the power?

For starters it only has 2 PCI-E connectors so that is a down fall as you need 4. Only has 34 Amps of total 12v power. IMO you need a much bigger unit. There are not too many out there that have 4 PCI-E connectors either. I have the PC Power & Cooling Silencer 750 Quad and it does but it is expensive. You are looking at a Quad and 2 8800 Ultras I would not even think about skimping on the PSU. At bare min I would want 40 amps of 12v power really 50+ would be good. Don't look at the wattage so much and focus more on the amperage as it is what really counts.

Ehhhh, I think that system would have a heart attack if you tried to game on it with that PSU.
I would go for at least 700W for that system.

LOL, never though someone would put it that way.
750W plus seasonic, corsair or Antec Quattro as a minimum. That psu wouldnt do a power on for that system. Try also Enermax or Silverstone PSU's, just make sure you dont skimp on the psu or youll have the world most expensive paper weights.

Not enough power for the two graphics cards, upgrade by at least 200 watts IMHO.
Ok seems like you people made it quite clear that it won't be good enough.. Now the question is what would be the best PSU to use for this unit?
Thanks guy for all the info.

Some of my favored units: Ultra X3 or X-Pro over 750W; Seasonic over 700W; PC P&C Silencer 750W; Silverstone Zeus, Decathlon, or Olympia over 750W; Thermaltake Toughpower over 750W; Antec TP-Quattro over 850W; Zippy Gamer or Serene over 600W.

Enermax galaxy 1000watt. nvidia recommends a 1000 watt psu for dual 8800ultras.

so you could run 2 ultra's, a q6600, water cooling (mcp655), 5 panaflows? on 850?

Looks like there are better options. I would have a good hard look at the PC P&C Silencer 750 Quad. Many say they are really loud when loaded. Mine runs nice and quiet, I think in the new revisions they did something with the fan to quiet them down.

i assume thats a 8/10? i'm happy with it, though its my first pc, so i don't really have any experience to compare it to. but its nice to find out i can run a q6600 and sli 8800ultra's.
So you think i should go with the Enermax Galaxy DXX 850W? Would that be my best bet.. Or do you think the PC Power & Cooling Silencer 750 Quad??I just don't want to cut myself short here.
Thanks alot guys for all your input

Csst,
If OW says "fine" and you want your own peace of mind and would feel more comfortable, go the bigger unit. You win either way!
i do want peace of mind i hate sounded like a broken record but i just want to make 100% sure this is the way to go that's all.

I'd pass on the Topower Tagans they aren't near the Zippy, or a Win-tact.

Burebista,
Agree. We could name a dozen or more capable power supplies, he had it down to two great ones. Adding more just causes confusion. There is absolutely nothing wrong with the two mentioned. Both are winners.

that made me laugh.... i bet Tagan's test bed for the psu's is a SLI/CF setup with a midly oced cpu with one cd/dvd,one HD,2 gigs of ram... if they consider that real psu load testing... seems they need to take a page from some nit picky psu reviewers. that tagan admin made it sound like such a big deal that someone spoke out about the regulation problems and over wattage of the psu. i wonder though if the psu is just 1300watts peak for 5ms.

You are indeed tilting at windmills. The OP speaks of an 8800 Ultra SLI and you recommend a 400W unit? :confused:

Goonda you misunderstand me. I never suggest to OP to go for 400W PSU with a Quad and 2 Ultra's.
All I want to say is that I'm a 400W guy for a normal rig single CPU/single GPU. In fact Corsair VX450 is my first recommendation for any combination single CPU/single GPU with decent OC.
FYI we have here a test with 2x 8800 Ultra + QX6700 @ 3.5 GHz = 497W DC in 3D Mark 2001 Nature on Sirtec HPC-500-A12S. 11.97V on 12V rail, but it was just a test, not meant to be run 24/7.
For OP a good 750W unit is more than enough. OW pick (http://www.ocforums.com/showpost.php?p=5272672&postcount=9) some for him.

The fun part is what I didn't say in the review is that I had to get two units. The data published was from the cleaner/better of the two. So they sound rather silly with their comments as two bad samples in a row doesn't make for as likely an outcome given the Topower lineage as it just being well a Topower....and I published the raw data for people to see in the oscope output.

Ha yeah. In theory the bead cores/ferrit cores/EMI filters (call them what you will) should help.....in practice though I haven't had any that did make a difference in our published reviews and the unpublished work I have done. For all the units I have had in that had them they would be better off taking the money spent on them to work on the secondary filtering instead.
From the same Tagan thread:
REMI Technology is actually a EMI (Electromagnetic Interference) protection by using a ferrite core and a shielding for your cable.
This will make your computer more stable by helping your wire output a lot less noise and ripples and therefore affecting a lot less your frequency sensitive hardware.
I think every PSU should be equiped with these.
German engineering
They think about everything !!Pure nonsense. First off, it is NOT German engineering. Next, EMI has NOTHING to do with ripple as being measured in many ATE based PSU reviews. One look at the timebase will tell you that. Ferrite beads are not broadband, so there is only so much you can filter. Nothing a properly shielded cable cannot take care of. Plus it does nothing to shield against EMI due to a high switching frequency. The case should take care of that or there ought to be proper selection of the toroid's core material. Sometimes, short of draconian measures nothing can be done about it to justify the pricing scheme.
I may be going far here but I wonder if you are exposed to electromagnetic frequencies for a long time if there is a possibility of being radiated...
But most PSUs and computer hardware have EMI shielding now, but I personnaly take it off on my motherboard to reach higher OCs...
But as far as PSUs go, I say you can't go without EMI shielding.
This guy is talking out of his ass. Where is he removing the EMI shielding on the MB? Most EMI emissions occur from the high freq traces on the MB, but having proper routing and ground planes, separation between Analog and digital sectors..etc will minimize that. Unless he is ripping apart the ground plane, I don't see how you can get rid of EMI shielding on the MB.
A quick biochemistry class about radiation.
I'm not sure if you guys have seen how cells regenerate.
Actually, they duplicate each other.
Like let's say to restore skin.
You will have one cell spread into two then these 2 will spread in 4 and so on.
If you expose a cell to radiations, you let's say alter it, or damage it because of oscillation in the atoms.
I'll keep it simple though.
If your cell is damaged or deformed by radiation it will then duplicate itself like the body is supposed to do and then you probably understand
that you will regenerate deformed cells and this is how a cancer works.
Defective cells spreading.
If you guys think i'm crazy or you don't know how EM Radiations works you can probably find it on wikipediAll I can say is OMG! This dude is YARWM (Yet another retarded Wiki-master) who has no contextual clue about what he is talking about. Bring on the tin-foil hats!
Paul, you are doing good work man. Don't waste your time on these morons. :)
