I would say minimum of 1000w if you're going to be overclocking.

Also a good brand PSU is needed (seasonic/corsair for example)



Minimum:
• 500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors Recommended:
• 600 Watt and four 6-pin connectors for ATI CrossFireX™ technology in • dual mode)

More importantly what are you doing with 4 5870's. I am asuming using linux, dummy plugs and... Oh, wait we can't talk about that anymore, um I geuss that or some type of server but I have no clue the wattage needed.

What a second 4 5870's with a pentium D I smell funny business alot more now.

EDIT:
