FSP and Fortron the same thing?

Hi

I´m going for a new Amd x2, X1900 crossfire rig and was looking for a good PSU. Saw the X-bitlabs review of PSU today and they recommended the FSP Epsilon FX700-GLN. Saw that the Epsilon FX700-GLN went under the Fortron namne..Is it the same brand as FSP?

And to another question. ATI recommends 36A on the 12v but I cant seem to find any PSU to meet these recommendations..Should I go with the Enermax Liberty EL T620AWT instead..? When comparing the FX700-GLN to the Enermax liberty, the FX700 has 4*12v at 15Amps and the Enermax has 2*12v at 22Amps..What does this mean?

Hope somone can help me..
 
FSP is Fortron, Sparkle and Power Man...so if you buy any one of those three brands you're getting a FSP built PSU.
 
ATI recommends that Amp across a Dual 12v rail. So basically my understanding is that you add the 2 12v rails together. So the Fortron has a quad 12v at 15A each making it a total of 30A where as the Enermax has a Dual 12v of 22A each making it a total of 44A. Now this is just my interpretation of what its supposed to be and I am probably incorrect in there somewhere. But that should give you a bit of an idea of what you are looking at.
 
12V rails aren't additive!

For that rig, you can't go wrong with the PCP&C 510.
 
Both Epsilons will power Crossfire easily, as the PCI-E connectors are on seperate 12v rails, but I usually suggest strong single 12v units for such high draw systems.

PC P&C 510W, Silverstone Zeus ST56ZF, Sparkle FSP550PLG-SLI, OCZ Powerstream 520W, Zippy HP2 460W and 500W, or the monster Zippy PSL-6701P are my usual recommendations.
 
1) if you look at the specs for the Enermax liberty Enermax® Liberty Series Power Supply - ELT620AWT (620 Watt) You'll note that it has 2 rails each capable of deklivering a max of 22A. BUT as Bbq says the rails aren't addative. you can see that the maximum combined 12v loading is 432W (36A).

2)The FSP as said has 4x15A rails which = a total of 60A now do the math 60Ax12v = 720Watts So again like the Enermax these aren't addative. The Full load shows what is available & is shown in Table. 1 Loading Table for Efficiency Measurements (Page 5)
3.3V = 10A = 33W
5V = 10A = 50W
12V1 = 13A= 156W = CPU1
12V2 = 13A= 156W = CPU2/PCI-E 2
12V3 = 12A= 144W = Motherboard, SATA, 4-pin molex
12V4 = 12A= 144W = PCIe 1
Total = 683W

So in summary the FSP 700 has 50A compared to the 36A Enermax.
Running a Single/Dual core rig SLI will give 12V2 =13A & 12v4= 12A
Compare this to the power consumtion here:-
Power Consumption of High-End Graphics Cards 103.1W /12 = 8.6A so FSP700 looks good. Enermax 620 No way.

Well... Now that my most common mantras are being regurgitated to the masses, and I now have 40 power supply reviews under my belt, I may just retire! :)
