Yes, 1998 3 into 1 splitters would be needed.  The break down is as
follows:

Three of the original power connectors would need 400 splitters, while
the remaining two would just need 399 splitters.  This would result in
4001 power connectors, or 4001 disks.  Because it's a Friday, here is a
simple program that verified my findings.

int main(int argc,char **argv)
{
    int con_a,con_b,con_c,con_d,con_e;
    int pow_a,pow_b,pow_c,pow_d,pow_e;

    con_a=con_b=con_c=con_d=con_e=0;
    pow_a=pow_b=pow_c=pow_d=pow_e=1;
    while(1) {
        con_a++;
        pow_a=con_a*3-(con_a==1?0:con_a-1);
        if(pow_a+pow_b+pow_c+pow_d+pow_e>=4000)
            break;
        con_b++;
        pow_b=con_b*3-(con_b==1?0:con_b-1);
        if(pow_a+pow_b+pow_c+pow_d+pow_e>=4000)
            break;
        con_c++;
        pow_c=con_c*3-(con_c==1?0:con_c-1);
        if(pow_a+pow_b+pow_c+pow_d+pow_e>=4000)
            break;
        con_d++;
        pow_d=con_d*3-(con_d==1?0:con_d-1);
        if(pow_a+pow_b+pow_c+pow_d+pow_e>=4000)
            break;
        con_e++;
        pow_e=con_e*3-(con_e==1?0:con_e-1);
        if(pow_a+pow_b+pow_c+pow_d+pow_e>=4000)
            break;
    }
    fprintf(stderr,"con_a = %d, pow_a = %d\n",con_a,pow_a);
    fprintf(stderr,"con_b = %d, pow_b = %d\n",con_b,pow_b);
    fprintf(stderr,"con_c = %d, pow_c = %d\n",con_c,pow_c);
    fprintf(stderr,"con_d = %d, pow_d = %d\n",con_d,pow_d);
    fprintf(stderr,"con_e = %d, pow_e = %d\n",con_e,pow_e);
    fprintf(stderr,"pow_a+pow_b+pow_c+pow_d+pow_e =
%d\n",pow_a+pow_b+pow_c+pow_d+pow_e);
    return 0;
}

Yea, but: "Say the power supply had five 5.25" drive power connecters"
:)
