Which would be better?

I'm thinking of upgrading the system in my sig to a DFI 875P-T with a 3.4E. Problem is that motherboard requires a 24pin ATX connection and my current PSU is only 20pin.

So which of these two options would be best?

1) Get a converter for the PCP&P 425 Deluxe

2) Swap the PCP&C for a Antec NeoPower


The most important thing is system stability. I'm also thinking off adding about 3 more hard drives for a RAID5 setup, a dvd-rom, and swapping the 6600GT for an eVGA 6800LE (underclocked Ultra), so keep that in mind.

well considering its you

I'll not bother to tell you to run the numbers
given there are enough amps, which I know you can determine
get the converter


for anyone else reading, this is a special case
with a very high quality supply and I still covered my ass


hmmm... just saw all those upgrades
now Im not so sure

run the numbers

ok, well a rough estimate gives me a max of 18.4 on the 5V line and a max of 27.5 on the 12V

both PSUs have plenty of 5V amps (38 and 40), so let's look at 12V

now the NeoPower has a combined 12V output of 33A, take off maybe 10A for safety margin and we're left with about 23A

the 425 Deluxe has 20A and if I remember correctly, PCP&C units are underrated so we'll say thats enough of a safety margin

so both seem kinda short of my requirements. I've all but ruled out the 6800 Ultra since my 6600GT does everything I need at 1280x1024, but I definitely want the RAID5 array, b/c right now I have nothing and it makes me very nervous. RAID1 kinda sucks, b/c you lose 50% off your space, but with RAID5, I'll have the added cost of a controller - anyway thats another thread.

I'm really leaning towards making the upgrade to the 510 PCI-E, since it's got a nice 38A 12V rating, has the 24pin ATX built in, and I should be future proof for a good 2-3 years
