Best Power Supply

[Cow2kie]

Im looking to get a new power supply. Whats the best most rock solid 550w power supply?

[bluediamond]

I have the Thermaltake Purepower 560 and I love it. I am running my wc pump, 2-120mm fans, 6-80mm fans, and 2 opticals without any problems.

[bluediamond]

The other advantage is that it comes sleeved and has two sata power connectors

Fortron FSP530-60GNA (http://www.newegg.com/app/ViewProductDesc.asp?description=17-104-968&depa=1) and the Antec TruePower 550 (http://www.newegg.com/app/ViewProductDesc.asp?description=17-103-910&catalog=58&manufactory=BROWSE&depa=1) are about as good as ATX PSUs get. (Or, if you have really insane amounts of money to spend get a PC Power & Cooling High Performance Turbo-Cool 600 ATX (http://www.pcpowerandcooling.com/products/power_supplies/highperformance/turbocools/index_tc_600atx.htm) unit.)

I'll prob go w/ the 550 fortron, since i like the 350 fotron i got for my sister.. and wtf that turbo cooled one is 350 bucks?!!?!?:eek: :eek:

If you get 550w Fortron/Sparkle/AOpen Power Units
please be aware that they have the 24pin ATX connector.

Also, there are two different models with different
amperage specs.


FSP550-60PLN = +3.3V=27A, +5V=-29A, +12V=18A,-

FSP550-60PLG = +3.3V=27A, +5V=29A, +12V=36A


NewEgg only carries the Sparkle brand "FSP550-60PLG".

Of course, the very best PSU are the PC Power & Cooling.
And they are expensive.

The PC Power & Cooling 510W Turbo-Cool Deluxe PSU is the best PSU short of $200 period. Stock, it ain't quiet - but PC Power & Cooling does modify it for you if you ask.

The, comparatively, low 510W rating should not lead you towards thinking that a 600W+ generic (or even quality) will be better. Power at room temperature of the PC Power & Cooling 510W Turbo-Cool Deluxe PSU is north of 600W.

No other PSU under $200 is as strong as this one. It will last far longer then the ATX standard will last. And I'm sure it will be powering BTX rigs (thru an adaptor of some sort) for years to come.

I agree 100%. It isn't quiet. And don't try to add a fan bus to the fan to quiet it down. They are temperature controlled. I tried and it overheated and shutdown. I had to wait an hour to restart it.(punishment for being stupid.):bang head

[Cow2kie]

I went w/ the fotron 550, I am not spending that kinda money on a psu.

[Hookem]

I hope you mean you went for the 530 Fortron...Unless you are running a dually the 530 is the one you want...;)

Just want to chime in and add a few words. The FSP550-60PLG at newegg comes with a 24-pin to 20-pin adapter and is perfectly useable on a regular ATX12V system. (I'm using it right now on a single P4 system as I type.)

Both models 60PLN and 60PLG are capable of delivering 36A total on the 12V rail. The only difference is that the 60PLN has *two* 12V rails, each capable of 18A whereas the 60PLG has only a single 12V rail with 36A. The rationale behind two separate 12V rails is that one rail is dedicated entirely to the CPU(s) for stability and noise isolation reasons, and the other rail is for everything else.

Both models 60PLN (under Fortron brandname) and 60PLG (under Sparkle brandname) are available at newegg. I've bought the 60PLG from them so I know it comes with the adapter, but I'm not sure if the 60PLN does as well. If not, you'll have to shell out an extra 10 bucks to get the adapter at ajump.com.

One comment I've seen about the 60PLG is that someone mentioned it emits a very high frequency noise somewhat like the soft high-freq noise you hear when you turn on the TV. This may bother you or it may not. I myself only started noticing it after reading that comment, and I don't find it bothering me much.

The main strength of the FSP550-60PLG is the 36A rating of the 12V rail. If you have a lot of hard disks and other devices drawing power from the 12V rail, this is the PSU to get, regardless of whether you're running a dual-CPU or single-CPU, ATX12V or EPS12V system. Very stable rails and pretty quiet operation (except for the soft high-freq noise mentioned above.)

Other PSUs with comparably powerful 12V rails are the Antec True550 EPS12V, and PC Power & Cooling's "Max-performance" series of PSUs.

That's fine but your question was 'What is the best PSU'. The answer is a PC Power & Cooling PSU, end of story. If you don't like the price, perhaps your question should have been what is the best PSU for the money :D The answer to that question IMO is the 530W Fortron.

[Cow2kie]

Yes, Fortron- FSP530-60GNA 530W, is what i meant.. not a 550

Great to know. :cool: :thup:

Yes but typically anytime you add a connection to the ATX plug you generally experience some loss... I have a 12" ATX extender that I had to use once, my voltages dropped pretty significantly. I liken it to a car... The motor puts out XXX HP at the flywheel and XXX - 20% (roughly) at the wheels.

That's not my experience though. My 12V rail coming out of the adapter is solid at 11.95V according to the bios menu.

If you look at the 24-pin to 20-pin adapter cable:

http://www.ajump.com/ajump/product.asp?dept%5Fid=4713&pf%5Fid=1F30230&sku=99%2D99%2D99%2D99%2D99%2D1F30230

I don't see how it's different than adding 2 inches of cable to the ATX connector. Ordinary cable should not add much resistance.

In your case, you added 12 inches of cable. A longer cable definitely adds more resistance. But I'd still be surprised if you're getting as much as 20% voltage drop.
